I’ve been using the 15w-50 for track use like the manual says,but I was wondering if anyone has tried the 0w-50, mobile one calls it a track only oil. https://mobiloil.com/en/motor-oils/m...l-1-racing-oil

[Try2paz]

id stick with the 15W-50

[SoCal Smith]

Stick with the owners manual and look into the 0w40 coming out soon.

I would stay away from M1 ESP 0W-40 on the track, at least until we receive an explanation regarding the asterisk*.

Here's my assumption... Since it specifically says not applicable to the ZL1 1LE... The tires are stickier and can endure more cornering g's. It's probably a little on the thin side and has a potential to starve the oil pump on sustained cornering.

Food for thought!


If you have a catch can and are not warranty complaint.. I'd use something with a higher TBN number (More additives) hence will not be LOW ASH.. basically not emissions friendly may lead to more soot build up(catch can will take care of this).. but, it will have a lot better heat protection and anti wear protection.

We all know DI has a problem with soot or build up on the valves because the way the fuel is introduced into the combustion chamber vs. port injection. The soft metal additives are typically what build up primarily (zinc, calciums, ect..), the new 0W 40 ESP low ash oil, low TBN number, and lower additive formula is a way to sorta combat this better and make way for emission compliance cleaner burning and the heavier weight will combat oil consumption as well.

The drawback is, lowering the additives and the TBN which go hand and hand... they do 3 things really good anti wear protection, resist heat, and longer intervals.. The higher the TBN the more of these additives are used. but, the higher the ASH is the downside for DI and emissions.

5w 30 and 0w 40 esp mobile 1 both have a 8.5 TBN that's pretty low for what's available on the market. You can get that in walmart synthetic oil.. and it has a ash content .08%

On the other hand the 0W 40 European mobile 1 or the 1 year and advanced oils have a TBN of around 12.5 they have a lot more additives also the ash moves to 1.2%... the European engines or standards are higher than the USA standards and use a lot more of these anti wear properties and go longer on interval changes..

ASH percentages..

0.5% to 0.8% considered low
Less than 1.0% medium
greater than 1.0% is high

If oil protection is a big deal and you want the most protection possible not caring about your warranty if your modded items like headers no cats and a catch can... I'd run the something with a higher TBN Maybe even a Euro oil since most oil companies do not post there full analysis this might be the only way to determine your getting ultimate protection. I notice that Castrol, penzoil and quakerstate had little to nothing in there make ups posted especially under the ash content and the tbn.

If your under warranty I'd probably look at schaffer's it seemed to have the lowest ash content at 0.7% for a synthetic i could find and they were on the dexos list not sure if they are 2 compliant yet though but, since the the TBN is lower I would change it more often but at least it would be the most emissions and lower soot oil for DI!

just FYI a little personal info

I have been using TRC oil for years at work they offer free analysis if you buy there product they will have a lab independently test it for free to see if its suitable for continued use.. In 20 years I never lost one motor gas or diesel and I was able to go from 100 hour as manufactured suggested to 400 hours. I did have to rebuild EZgo motors it would not of matter what oil i used they seemed to burn oil and foul the plugs at about 12-1400 hours. I never figured out if it was rings or valve seals I just did them both since i pulled the motor(never did i have to replace any bearings, camshafts, rods or cranks it all looked brand new). anyhow the inside of the ezgo motors looked new every time I couldn't believe it.

With my car I chickened out at 16000 miles on the same oil that came back saying suitable for continued use..

I have to admit I'm skeptical for a good oil not to be sold on shelves and only by selling door to door and customer recommendations.. I used there oil in my truck and 5th gen I haven't done so yet on my 6th gen mainly cause I don't have the proper weight laying around. but it has a TBN of 15 plus which is unheard of and some companies will say that impossible. Take a look at AMSOIL its TBN is up there actually the highest you can buy at a retail outlet.

I'm no way a oil specialist but, I have attended a lot of educational classes and meetings on lubricants with sales and chemist. FYI the best grease I have found has been the TRC Paragon 2000 i'm on my 4th year equipment lease and I have only replace 1 roller bearing out of about 200 on our fleet in the past with using the manufacturers grease by John deere (they recommended) it would of been 5 or 6 rollers a year if not more.


remember oil is oil lol!

Interesting theory. Makes sense, especially with a wet sump.

ESP 0W is recommended for the LT5. ZR1 cornering Gs exceed or are at least on the same level as the ZLE. Dry sump oil delivery may very well be the difference maker. That would explain the recommendation for Z06/LT4 as well.

I like the way you think.

Great info and insight. Thanks for posting.

I'm thinking the lower Ash content is also beneficial to CATs and (at work) Tier 3 and 4 diesel particulate filters.

I'm holding off on the CC until I get good info on any warranty issues that it may create. So, low Ash content, low TBN and frequent changes will be the route that I choose until then. You are right about Amsoil, great stuff, but getting it shipped here is cost prohibitive for me. I like Mobil 1, but I'm truly impressed by the properties of Motul 8100 X-clean (Dexos 2). Until I hear from Chevy about the * regarding the RPO A1Z, I will probably go that route.

Thanks again for posting. Really good info.
