UB or other guys that do HPDE. How often are you changing engine, trans, and diff oil? I do 4-5 sessions in a day and presently change the engine oil after two track days. Is this excessive or in order?

What is the current amsoil recommendation for the mt82 and diff?

Thanks for the tips!

Beating a dead horse here so please forgive me. The new update has me a bit confused. I run amsoil 10w30 in my 2013 5.0 full bolt on cobra jet car on e85. I live in south Florida. The car sees weekly trips to Mexico (numerous runs) and drag strip also it is my daily driver. Most trips range from 10-45mins. With the occasional road trip 2-3 hours. With the new revision in your suggestions what is your recommendation for me? Appreciate the time and effort you put in to help us all.

Thank you!!

Thank you!!

as in Cobra Jet intake manifold car, or a real Cobra Jet? I'm assuming intake manifold car, since you said "Mexico".

The reason why I changed to 5W-20 Signature Series in my bolt on only 5.0 is.......I beat that car up for nearly 10,000 miles with that lubricant, and the UOA came back flawless. After 30+ track passes on the 1/8 mile too. I was shocked. Your engine is good either way.

All recommendations for your car are in post #1, and covers the rear differential and MT82 transmission. Two track days is excessive for Amsoil Signature Series, but not so much for cheap lubes. I've seen UOA's from dirt track cars running the same fill of Amsoil for 4-5 weekends. Guess what, the lubricant was wasted when it was drained, with the exception of high lead from leaded race fuel. You don't have that problem.

Thank you for the input. I'll stick with the 5w 20 SS based on the advice in that post and do more than two events. I think I'll also try the amsoil dot 4 fluid.

There isn't a UOA thread in the S550 section so I guess I'll put this here. This is with ~200 miles of track time at Circuit of the Americas being the first mileage on the sample, and the rest is daily driving here in Texas. I know some folks have been waiting for a sample of the new 0W40 SS. I ran this car pretty hard at COTA, probably about as hard as you can run this car considering how fast and hard that track is on cars. I think 0w40 was perfectly up to the task according to the results.

I switched to the Amsoil 10W-30 SS back early this year after running Motorcraft since the car was new. At the time I switched the car had right under 20K miles on it. Just ordered some of the ALM 5W-20 last weekend after seeing that the thread has been updated. The car has 25K on it now so I know it's a little early to change the oil already but my conscious wouldn't let me go any longer, lol.

FWIW mods are in my sig and the car has been a daily driver since last August.

Hey guys, just picked up my '14 GT M6 last month, during my searches of the interwebs, I came across this thread. Just wanted to say thanks to everyone who helped contribute to this wealth of information as its been a big help for me as I decide which fluids to run in this thing as a daily driver.

As Budwise stated above. There is no UOA thread for the S550s.

My car just turned 14k miles and have driven it, brand new since Dec 2014. I have been running Pennzoil Ultra Platinum 0W-40 since 2k. I just got my Flexfuel tune and will be running E85 virtually 100% of the time going forward.

In reading another post by Unleashedbeast, he stated to run Dominator 10W-30 for those running E85 or over 600rwhp.

Are folks running e85 with occasional drag strip and hard street driving running that oil? Or is 10W-30 SS OK instead?

Thanks for any help.

Do we have any analysis information on Joe Gibbs Racing Oil? Tim @ MPR said that is what he recommended when I dropped my motor off to get built yesterday. Was curious because I haven't seen it listed on here yet.

You probably won't find it on here. I'm just about the only contributor to this thread and all I run is Amsoil Sig Series 10w30.

Another sample coming up in the next month or so, should have 15k miles on this one.

Thanks, JDos1.

Are you running E85?

I am not. With 14K mile intervals the oil's additive package would have been long depleted. Can't afford E85 anyway, I drive close to 3500 miles/month.

I ran Amsoil 10w30 SS N/A and the 0w40 boosted before I blew the motor. Gonna try the Gibbs Racing JR20 as I'm sure Tim knows what he's talking about. I'll do an analysis and post it here when I change it

So far, I am very impressed with Amsoil AZF 0W-40. It's performing as expected, and look how low wear metals are for this 6,000 mile sample AND 200 miles of HPDE. What I've learned about 0W-40 thus far, it shears to a heavy 30 grade with some miles. That's expected of a lubricant with an SAE wide spread. Example, 0W-40 would have a higher percentage of shear than a 10W-40 would.

Great sample, I'd be smiling if that were my engine.
