I would have to go with M1 TDT 5w40.

I was looking at OVERK1LL's UOA and then looked at the PDS for M1 TDT. All things considered (performance & availability), M1 TDT is the best oil out there IMO.

I would not hesitate to use this oil in a high performance gas engine either. I know it's holding up very well in many of the VW engines too. All things considered, I'm not sure this oil can be beat. Rotella 5w40 & SSO would be up there also.

I think the best oil is the single quarts of Havoline I picked up off the highway after the Walmart truck rolled over and broke open. I felt it was my duty as a citizen to help clear the roadway to get traffic moving....

I would be inclined to say Amsoil 0w30, as you could run that in just about anything and it has awesome long drain capabilities. So if any oil deserves the title of best overall oil that can be used in just about any engine, I'd have to say that one.

I would have to say PP.

Cost and availbilty is a factor.

That being said, I almost never buy it. I have a bunch of M1 and SynPower I bought on the cheap right now.

Best to me is like the Goldilocks Fable. Not too big...not too small....but the right oil for the right application at the right viscosity at the right time & price too. This goes for oil filters as well. Not to mention the right oil change interval.

I'd pick an Amsoil Eao oil filter.

Amsoil 5W-30 HP for this weight is great!

I'd run it 7500 miles....though it can go longer.

With 31 years of successful engine maintenance, as in very clean, long lived, and never a failure. I most humbly choose for my future motoring excellance, joy, and complete confidence, the choice of auto engineeres around the world, M1 oils.

I'm just amazed an experienced guy like Buster started such a thread!

M1 TDT 5W-40 is indeed a great oil. But I would not run it in a XW-20 Honda. I won't give a real answer but I would think an XW-30 could better straddle both sides of the viscosity question if you could only pick ONE oil.

Just having fun with it. I know there is no best but I was just saying if you had to consider ONE oil as the BEST, considering performance, availability etc..

M1 TDT & Amsoil SSO would get my vote. SSO would be 2nd though due to price and availability.

TDT could be run in a Honda although it would not be ideal.

I dunno. I read stuff and think about stuff, and sometimes change my mind. Right now my opinion of RP, Synpower and Syntec are about equally tops but for different engines.
Flat lifters, RP for sure.
Synpower? Hard to beat their confidence in the 300K guarantee.
Syntec? Well it has lots of molly...maybe better for startup on a lower usage vehicle. (Maybe)

Guess I'll go with RP.

In Canada I'd have to say Esso XD-3 0w-40 or 0w-30 given that it's probably equal to TDT in most every respect and sells for almost half the price of any other synthetic here.

Delvac 1 ESP 5w40 is generally considered a better oil than M1 TDT 5w40, looking at the approvals and certs it has vs. TDT, and the assumed basestock.

I'm running the older TDT, the CI-4+ formula which is identical to the older Delvac 1, and has all the same certs.

It's a slow mover up here, so there seems to be lots of stock of the old stuff.

Redline 5W-30 for high temp performance and deposit control/film strength/HTHS/wear control.

Amsoil SSO for extended drains.

Since I don't like the idea of 15K+ mile OCIs, I'd have to go with Redline.

Dead serious, why? Do you like VIIs, do you have something against POE's inherent superiority regarding high temp deposit control, film strength, and it's ability to cling to metal; or against Redline's moly/ZDDP heavy add pack?

Yes, cost no object with sub-10,000 mile OCIs in mind, I would pick Redline every time.

Yes, he does. Try out the other thread "only the facts" and you'll see the hatred for Redline.

I just saw we're only doing one oil. It would have to be Redline 10w-30. It can satisfy the 40wt specs and as I've proven it can be run in 20wt spec'd engines. 5w-30 I'm sure will do the same thing.

The question is kinda like asking, "what is the BEST detergent out there? And by the way, I mean *ONE* detergent to wash your car, your dishes, your laundry, your hair, your dog, mop the floor, clean the windows, shampoo the rug, clean the oil stains off your concrete garage floor, and your wife's antique wool sweater that belonged to her grandmother."

Given that, I'd have to pick Woolite. It might suck at cleaning the garage floor, the dishes, the car, and most everything else but at least my wife wouldn't cut parts of me off for ruining the sweater.




I think I get the basic idea, though, and I agree that M1 TDT is a pretty solid all-around pick. But back to the detergent example... I've got 3 engines that really don't want Xw40 oil. Of those, 2 are flat-tappet muscle car engines, and one is a modern roller-cammed economy car engine. One size just doesn't fit all, so I use RTS, RP 5w30, and M1 5w30AFE in my lil' fleet at the moment.

I love the fact that Redline uses majority POE base stocks, but that doesn't mean it's a better oil than one that is majority PAO based.

I was just toying around with the idea that if you had to pick ONE oil, what would it be. SSO is high on my list. Redline's UOA's have been very mediocre, for what they are worth. (opinions vary)

TDT and D1 have always been a cut above the normal Mobil 1 line. Different oils for different applications but in their respected categories they seem to hold up a lot better than Mobil 1.

I would have to use TDT also,GREAT oil!!!!

i thought about buying a 55 gal drum of it for all my stuff and family.

the only reason i think i haven't is because i like shaking my oil and kinda hard to shake a drum,lol

I can't believe that nobody on this forum has said GC or asked if said chosen oil could be mixed with auto-rx.

If I could only run a single oil it would only make sense to choose a grade that can be run in the vast majority of engines so a 5w-30 is probably a fair place to start. Some older vehicles don't like synthetic oils because there are too many leaks so I'd eliminate synthetics and go back to a blend.

So my choice would be any 5w-30 blend and the OCI can be adjusted to better suite the cars needs.

I've seen some pretty outstanding Redline UOAs, especially consecutive UOAs.

But what really makes a UOA mediocre? A few ppm of a wear metal or two? I will admit Redline falls short of Amsoil's TBN retention, but as someone who doesn't like the idea of going over 10,000 mi OCIs under typical mixed driving conditions anyway that doesn't concern me in the least.

I love the fact that Redline uses majority POE base stocks, but that doesn't mean it's a better oil than one that is majority PAO based.


It does mean that it will have some inherent performance advantages though, and it will have the potential to be a better final product assuming the blender knows what they are doing. I truly believe Redline knows what they are doing. Every Redline product I have ever used has been absolutely top notch, be it fuel additives, assembly lube or grease. Amsoil and Redline are the two boutique manufacturers that I actually trust.

True Ben.

German Castrol was the oil of choice a few years ago. Today, not so much.

I was just thinking the other day as to how far I might push my Sienna w/ the present regimen of adding a qt of synth every 2k and just not OC for a good while. Presently I'm dropping in PP on top of the original Pennz. HM & PP mix fill. But I was thinking, to do this right, to hit the oil with the most robust topoff available and seriously extend the OC - that would be M1 TDT (assuming an original M1 fill).

How do you know the M1 TDT/PP/PHM add packs won't compete with one another?

I really don't understand this fascination with mixing oils. I can see it in a pinch, but that's about it.

Dead serious, why? Do you like VIIs, do you have something against POE's inherent superiority regarding high temp deposit control, film strength, and it's ability to cling to metal; or against Redline's moly/ZDDP heavy add pack?

Yes, cost no object with sub-10,000 mile OCIs in mind, I would pick Redline every time.

Sorry, it's hard to tell on the 'net.

I know a few people running Redline in street cars, but they are usually pretty serious street cars. The kind of cars people don't mind plunking down $9/qt to protect. If I wasn't a tightwad, I'd run it in everything.

Ben99GT and Buster. I have no fascination w/ mixing oils. I fell into my present mixing of PHM and PP due to a need to use some the last of my stock of each. And concerning mixing in the TDT - re-read my previous post - I stated "assuming an original fill of M1" (in the event of adding TDT) - I wasn't stating that I'd add TDT to PP, etc. That's sick.

Cool. Makes sense then. Nothing wrong with it at all as all motor oils are compatible with one another but you don't get to see the full benefits of a single formulation when mixing. In your case it's different.

Ive seen Redline throw some junkie UOA's but really its only the first two or three UOAs and then the wear metals go way low and everything seems smooth.

I run it in my primary vehicle. I would trust Redline to any high performance\high demand application that would see severe use.

If you wanted a great oil in ANY car for long term OCI's Amsoil SS0

hmmm, for me, Mobil 1 EP. I have used Mobil 1 since 1983. I have used Mobil 1 more often then the sum of all the other synthetic oils I have tried. It's easy to find, priced at a price I am willing to spend and never had a engine fail or need rebuilding in any car that I have used it in on long term basis. I never buy new cars. I buy used cars, approx 5 to 10 yrs old and keep them until they are ready for the junkyard. Last car I junked out, the engine was still running great @ 320,000, but everthing else was falling apart on the car and the rebuilt trans was failing. I have never owned a high performance car, so I have not felt the need to try Redline, Neo or Amsoil. I may give Lubro Moly a try or GC next oil change....bottomline is I have confidence in Mobil 1

The question is kinda like asking, "what is the BEST detergent out there? And by the way, I mean *ONE* detergent to wash your car, your dishes, your laundry, your hair, your dog, mop the floor, clean the windows, shampoo the rug, clean the oil stains off your concrete garage floor, and your wife's antique wool sweater that belonged to her grandmother."

Given that, I'd have to pick Woolite. It might suck at cleaning the garage floor, the dishes, the car, and most everything else but at least my wife wouldn't cut parts of me off for ruining the sweater.




I think I get the basic idea, though, and I agree that M1 TDT is a pretty solid all-around pick. But back to the detergent example... I've got 3 engines that really don't want Xw40 oil. Of those, 2 are flat-tappet muscle car engines, and one is a modern roller-cammed economy car engine. One size just doesn't fit all, so I use RTS, RP 5w30, and M1 5w30AFE in my lil' fleet at the moment.



The best detergent is Gain,hands down ;\)

For me; it's Valvoline Synthetic.

The Shell Helix racing oil used in the Ferrari Enzo must be the best; it's the most expensive!

Or is it the oil used in the Bugatti Veyron? Oops, I think it's something like Mobil 1....

I agree, but we can't get it here.

So I'd choose Motul 300V 0W-20. I know it's a bit heavy but it will have to do until they come out with their 0W-10.

An oil that would work in everything and cause no engine problems would be most synthetic HDEOs. Rotella-T 5W-40 would be my choice.

As for a 30 weight oil, I think Pennzoil Platinum shows exceptional results every single time it is used. Especially how long it can go for the price. 10k miles seems to be nothing stressful on it in most every UOA.

I would have to go with M1 TDT 5w40.

I was looking at OVERK1LL's UOA and then looked at the PDS for M1 TDT. All things considered (performance & availability), M1 TDT is the best oil out there IMO.

I would not hesitate to use this oil in a high performance gas engine either. I know it's holding up very well in many of the VW engines too. All things considered, I'm not sure this oil can be beat. Rotella 5w40 & SSO would be up there also.



Buster:

Please report to the nearest woodshed for your richly deserved spanking.

Seriously though, this sort of question is fun, but impossible. The only reason it is remotely workable is that we're a bunch of oil-obsessed freaks who like to talk about this stuff. My wife thinks we're all certifiable -- and I don't mean API or ILSAC certifiable. . .

So what of M1 5w-40 TDT? Looks like a great oil, but it's utterly worthless to me. In fact, with it's 100C vis (40 wt of course), it must be on my NEVER USE list. Given a "gun to the head" choice between TDT and DD* 5w-30, I'd take the DD every time for my cars.

* DD = Decapitated Dog, a/k/a Wolf's Head.

M1 5W-40 TDT in CJ-4 form disappointed me in the category of deposit control in my VW 1.8T. It varnished in one 5K mile OCI.

I still haven't found what I'm looking for. Probably because I want free oil that can clean an engine in one OCI, last >10K miles in all of my engines without causing deposits, and prevent wear as good as the best of them. I am SO tired of having to change the oil in my VW 1.8T every ~3300 miles just to keep deposits from getting worse. Amsoil needs to make a 40 weight version of SSO!

Pablo, is DEO any better at deposits than TDT?

I can't say with data - on paper it should be, and users report good cleanliness. There are at least four or five guys here using it. One guy posted a pretty good UOA.

I wonder who that guy is It'll be a while before my VC comes off though.

JAG, you might also try a 502.00 5w40. Appears to be many 1.8T owners who can go 5K miles with them.

I am very surprised a good CJ-4 5w40 varnished up so quickly though.

Stock, or modded?

DEO looks very similar to TDT. Maybe give Redline a shot?

Ya. me too. And those 55 gallon drums are kind of flimsy when they are completely full, and often collapse when I am holding them over my head giving them a good shake....

No but I have considered it. I'm a little turned off by using HDEOs in gas engines now. It may be human weakness...painting broad strokes based on experiences when they should be thin.

Yes to Red Line. After my bad TDT experience and my ever-present varnish battle, I have begun using some Red Line for its high ester content which acts as a better solvent for varnish than Groups III and IV. So far I'm pleased but I have been to afraid to go 5K miles again to get a more direct comparison to the TDT "failure". I also scored on a Target sale of M1 15W-50 EP for an amazingly low price of $1.79/qt. which I could not pass up. So I've started blending that with Red Line 5W-30 and a little Synpower 5W-20 (don't ask why...no great reason other than wanting a thinning oil) to get a ~14 cst viscosity at 100C. Happily, the engine has never started and run so smoothly in its 120K mile life! The improvement in startup sounds and smoothness is is blatantly obvious so you can take this to the bank. When my ghetto stash runs out, I'll need something else to use. Pep Boys has begun selling M1 5W-40 ESP Formula M and 5W-30 ESP Formula for $6.99 qt. which meet some uber-rigorous oil specs so they are on my mind. They are not great for winning high-ending TBN battles but my VW ruins oils via deposit problems before the TBN is too low anyways.

D1 ESP is too expensive and I expect some similarity to M1 5W-40 TDT CJ-4.

Schaeffers 9000 5W-40 has shown too many high lead UOAs for me to try it.

I used many VW 502.00 oils: GC, Syntec 5W-40, M1 0W-40, previous formula of Valvoline Synpower 5W-40, Lubromoly 0W-40 and 5W-40, and the original formula Amsoil 5W-40 that met VW 502.00.

I hold M1 0W-40 in high esteem for deposit control and good gas mileage. The Amsoil 5W-40 I used was good except the engine felt sluggish on it and gas mileage dropped relative to M1 0W-40. Valvoline 5W-40 was good all around. The rest disappointed excessively in one or more ways.

My 1.8T is stock. I do mostly 35 minute trips. I also do hard-driven interstate trips once a month or two. That probably has something to do with my varnish battle.

M1 5W-40 TDT in CJ-4 form disappointed me in the category of deposit control in my VW 1.8T. It varnished in one 5K mile OCI.

I still haven't found what I'm looking for. Probably because I want free oil that can clean an engine in one OCI, last >10K miles in all of my engines without causing deposits, and prevent wear as good as the best of them. I am SO tired of having to change the oil in my VW 1.8T every ~3300 miles just to keep deposits from getting worse. Amsoil needs to make a 40 weight version of SSO!


JAG:

Please forgive me if you have already told the story in more detail -- I get spread pretty thin between my insane job, and trying to keep an eye on as many fora here as possible. That said, is there any possibility that the varnish episode is chargeable to a problem with the car, not the oil? PCV or cooling issues come readily to mind, but there could be something else. No CEL, I presume? And I don't know what the oil filler opening in your car reveals, but I shine a flashlight into mine at least once a week, when I check oil, to make sure that I can't spot anything starting. Are you unable to routinely look inside?

Buster it's ok to change your mind, but I preferred your original thought.

I have no evidence that there is anything currently wrong with the PCV system (replaced once already) or the cooling system. No CEL either. The oil filler opening in this engine reveals valve cover metal, cylinder head metal, and plastic cam cover. So it's decently revealing about top end varnish and I do usually check it pretty often. I slacked during the M1 TDT run and didn't notice the increase in deposits until I changed the oil at 5K miles. The PCV hoses and metal vent for the valve cover had some serious deposits in them that were not there before using that oil. The valve cover region that I could see had just a little more varnish than was there before. A typical owner who looked at it probably wouldn't have even taken notice...it was a matter of increased browning, not a blatant black and white difference.

Those driving conditions are nearly ideal, engine always gets warm and the highway trips get things really warm. No seeing any really hard conditions.

Hm. Might try a 504.00 oil? They are backwards compatible with previous sparker specs. Mobil 1 ESP 5w30, ELF/Total has 'em too.

You have the VW or Audi 1.8T, 150, 170 or 180 HP version?

Today I was reading a book online at Google and it discussed oil degradation. According to that my driving style takes a relatively high toll oxidatively on the oil. Shorter trips were said to take a bigger toll on the detergents (think TBN). That makes sense since I'm seeing high temperature deposits which are largely an oxidation by-product. I'm sure that I'm NOT knocking down the TBN anywhere near 1 or 2 in <5K mile OCIs.

Mobil 1 5W-30 ESP Formula is a possible candidate. VW 504.00 is one of the most stringent gasoline engine specs according to the spider diagram at Lubrizol's site (or maybe it's the other big additive company). That's intriguing but so is Mobil 1 5W-40 ESP Formula M (MB-229.51) and Mobil 1 5W-40 Formula M (MB-229.5). I can get the latter from my local MB dealership from their bulk tank for $4.25/qt. which is probably too hard for me to pass up. Noise, vibration, and harshness with this engine feels better with thicker oils IMO so I'm leaning away from the M1 ESP 5W-30 Formula.

I have a VW 1.8T with 180 hp. It's funny how I have so little to talk about oil-wise with my BMW 135i and Subaru WRX STI engine. Hopefully it will stay that way!
