https://540ratblog.wordpress.com/ Not sure if anyone has posted this yet....did not go through all 27 pages haha. A buddy of me sent it to the other day. A very long read but interesting and very infomative.
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!!
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!
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.
Thanks, JDos1.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.
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.
