Actually now that I think about it, that would be Grp 5 oils, correct?

Agreed. I used the original Mobil 1 for many years successfully, doing one year, average 18,000-20,000 mile OCI's. Since most M1 formulations are now SM's, I use M1 10W30 High Mileage, which is still SL. I use it in my Pathfinder and all of my small engine outdoor power equipment.

Try putting a little motor oil and some cooking oil on a hot surface exposed to the air. After a half hour, which do you want on your cylinder wall?

There are vegan motor oils?


Yes, somebody posts a link to the latest wonder every few months. They will work with enough antioxidents in them, at least for a while.

Over THIRTY years of service with a product that has not given you any problems vs TWO internet posts?

PS: If your post was sarcastic I did not get it... Hopefully it is.


It has to be sarcasm. I guess the new BITOG is not going to change, newbies just need to learn how to interpret the writings here. It's like the guy who posted the "top 10 Syns" - he hadn't actually used any of the oils, but by God he has a list of the top ones........based on what he sort of cursorily read on BITOG. Scary [censored]. scary [censored]. scary [censored]. scary [censored].


thats funny..

Amen. +2

Oh, also no mineral oil nor olive oil will go in my motor.

C. Killing babies/ etc

If I had to choose an oil not to use, it would be House Brand oil. (IE Advance Auto parts brand 5w30)


I share your opinion on the ads. But, as to the house brands... there are some very good oils NAPA is Valvoline. Auto Zone is I think sopus, WalMart is Warren Performance these are all very good oils. Who makes PEAK? I only see that at Pep Boys. But, I do respect your opinion.
 
Without reading any of this thread:

I will never use any Mobile 1 oil.

Based on the fact that M1 5W30 clearly does not meet claimed specifications.
 
Pretty bold statement without any proof to back it up.. XOM is the 800 lb Gorilla when it comes to synthetic lubrication. They *are* the benchmark.
 
Agreed.

M1, Amsoil, Redline, R Purple is the top category for synthetic oil. all previus data posted here is proof enough for me.
50% of Nascar uses Mobil 1. Those guys know a thing or two about lubrication. On the amatuer Motorcycle racing circuit almost all the guys use either M1 right off the shelf or Amsoil and some Castrol.
That doesn't make it the only good oil but, it's a great oil.
 
Hey I have idea based on e-mail Newsletter I got, anyone willing to test theri oil and post the results ?

***

I just have got an excellent short article from SynLube (and no I am not promoting their products, but I do use them so I am on their NEWSLETTER e-mailing list).

Simply this PAO and Esters conduct heat differently and have different heat capacity !

I did not know that, so instead of super expensive test by IR you can actually in your own kitchen find out HOW MUCH synthetic is in your oil (what ever brand you are addicted to).

Here is the link:
http://synlube.ning.com/notes/index/show?noteKey=MAGIC_%231_%E2%80%93_Lower_Operating_Temperature

And here is my idea.

Get plain PAO 6 from company like ExxonMobil
Get plain API SA SAE 30 motor oil form place like Wal-Mart

Put an electric heater and thermometer into any convenient container (I prefer chemical glass column) and time the heat up from 100F to 300 F.

Then you can do that with your favorite oil, and the FASTER it heats up (less energy it takes to elevate the temperature) the more PETROLEUM is in the blend!

I could se NO difference between petroleum and supposedly "synthetic" Quaker State ! But a big differentce between the SA and PAO - so this apparently does work!

Interesting, but then QS is API Group III "synthetic" so this simple test really works !!!

(My idea of course, but I discussed it with the Guy at SynLube).
 
I cant say that I would never use a certain oil but I am not real fond of SOPUS brands,Castrol or Havoline.They may be good oils but I prefer to avoid them.

I do like Mobil oils,they are really my first choice in oil but the local china mart doesnt carry the weight I want in the 5 qt. bottles.I also use Super Tech and have used it quite a bit and may use it in my next oil change in a few days.

This is how I would probably rate my choices:

1.Mobil
2.Super Tech
3.Havoline
4.Castrol/Sopus
 
In no particular order:
  • Anything from Valvoline (as long as Ashland owns it)
  • Any discount or regurgitated oil like Ring Seal, Top Kote, etc. (my engines are worth more than that)
  • Any boutique oil like Amsoil or Royal Purple (price and availability)
  • Anything from Citgo (up yours Chavez)

SOPUS has the majority of my business because:

  • I personally know people in the Pennzoil organization and I am supporting them and their families
  • They make some great products at a good price point (are SOPUS products the most widely used???)
  • SOPUS products are available most everywhere
  • With names like platinum and ultra how can you go wrong? (j/k)
 
For me this is a no brainer. If a oil does not meet current specifications for my vehicles or the ones that I service then they do not go into the crankcase. Name brand and reputable certified house brand dino oils are fine by me , and satisfy the requirements of 90% of the vehicles on the road. If it is a high performance or turbo/supercharged vehicle it will get a dose of Mobil 1 or a quality SOPUS product. In my opinion a boutique oil such as Redline , RP or Amsoil is unnecessary, while great oils I do not believe they perform any better than M1 ,PP,Edge etc in a real world setting.
