When people say: "Omg.. my oil is black! I need an oil change" we all know that the oil being black is not an indication it needs to be changed. Is the same true for oil being relatively clean? In my case: Amsoil SSO in use (in a Honda) for about 15k km and the colour is like maple sirup. Does...

It was a bit awkward though as it was a present from my brother-in-law for my father. I saw the bottle and I had to laugh and asked: what's this? My fatehr said: that's for my car. So I said: that stuff is NOT going into your engine, over my dead body. My sister was a kinda upset, so I...

Well.. I'm not posting the UOA because its not mine but I was surpriced to see Redline 5W-20, used in an F22 engine (Honda S2000) shear down to 7.81 cSt in only 1300 miles. No fuel dilution, high flaspoint. TBN was 5.6 According to the website this oil starts life at 9.1 cSt. The "30 weight...

Hi, Do you get the Honda 2.2 i-CTDi (N22A2) diesel engine in the US? It's been around since 2003 overhere (Europe). If so, what oil do they recommend in the owners manual? A search for "honda" in the diesel forum only produced 19 hits. I'm thinking it would probably be a 30 weight, but who...

Why? Because I'm looking for some posts about Redline 5W-20 in the PMCO forum. So I search for: Redline. What do I get: a lot of Re: Redline 0W30, almost a full page of it, the other 7 pages look the same, replies, replies. Next search: Redline -(minus)Re What do I get.. see above. Somebody fix...

Hello I've searched this forum using the word "mixing" (in the subject) as the key but found nothing. I have a 2 types of brake fluid left over. Both are not old and stored properly, one in a steel container (ATE) Point is, what is left over per type is not enough to do a complete fill & bleed...

Hello, Over a year ago I bought 2 x 4 liter of Valvoline XL-III 5W-30. For a coupe of weeks I've been trying to get some more but were unable to find any at all. Automotive shops in the Netherlands (at least in the area I live) don't have it anymnore and are unable to order it, a while back I...

By looking at it I mean. Would it show up at a UOA? If so, how? I bought some cheap 10W-40 this weekend, unknown brand, no website. The oil does have an API SL/CF, ACEA A3/B3, MB 229.1 and VW500.00/505.00 qualification. On the label is not a word about recycled oil. It is labelled as semi-syn...

Hi, Is the Valvoline Maxlife FE 5W-30 (FE = Fuel Economy) new or old stuff? I can't find it on the Valvoline.com website. There is some info on the Valvoline.nl site but not much. Google found the product specs as an official Valvoline pdf. Those specs say that it's a "premium synthetic blend...

Wear metals not that bad. Original visc = 9.6 cSt @ 100C Fuel dilution is still present. Could that be that I only drove for about 15-20 minutes before taking the sample? How about the TAN? Is this good or bad? Will the oil last me 30k km next time with a filter change at 15k km? Thanks for...

Early this week the Amsoil SAE 190 finaly made it across the big pond and on tuesday afternoon it went in my aftermarket geared diff of my Honda S2000. Honda specs a SAE 90 for the diff, Richmond recommends a 75W-140 for its gear sets. This syn single grade will be more shear stable then the...

As the title says, if I mix some leftover SAE 90 with a -24C pour point with some SAE 85W-140 with a pour point of -12C in a 1:4 ratio do I get (4x12 + 24 = 72, 72/5 = )-14.4C? I guess it works with viscosities, does it also work like that with pour points? The leftover SAE 90 has an additive I...

As in the title, is there a straight SAE 20 oil? This question is coming from the SAE 30 debate / posts. A straight 8.8 cSt (or so) oil would be nice to have, wouldn't it? With a search could not find anything here and all the oil manufacturer sites I have seen don't list it. (Shell, Mobil1...

The oil went in at 115200 km and was changed at 126012 km. During those 10812 km I added 4.5 liters to keep the level up. Fe is kinda high. Why only Fe and not also lead and copper? Flashpoint was lowered because of fuel dilution. Now I'm using an extra PCV valve to create a vacuum in the crank...

After reading a lot of thin vs. thick posts I have made up my mind about oil at operating temp. Currently I'm using 0W-40 and after reading about that oil on this forum I'm going to get 0W-30 (GF-4) next time. Less VII is better I guess. But how about the differences in oil at a cold start. Lets...

Hello, I'm saying "vs" in my topic title because of this: cars are being recalled back to the dealer all the time to solve mechanical issues, the S2000 had a modification of oil jet bots and spark plugs. There are maybe more, I have to check the S2000 forum on that one. My point is, the owners...

Hello All This is my first post inhere, thanks for the Junior Membership I own & drive a Honda S2000, of about 6 years old with 115500 km on the clock. Lets get straight to the point: Last weekend I changed my engine oil & filter from 5W-40 to 0W-40. Same brand, being Shell Helix Ultra. On...
