There are a lot of people that aren't going like that you mention T6 and Amsoil in the same sentence I agree, by the way. I've always had good results from Rotella. People still like to use expensive fluids because it makes then feel warm and fuzzy, though. Or maybe they have a specific reason they need to use it I dunno. Either way, it's still one of the best-kept secrets in automotive fluids.

 

 

It's good that you have a point of reference and data to back your decision, though. Most people are like, "I run only AMSOIL 24/7" but when you ask why, they don't have any quantitative info. Just something along the lines of "I don't like to take chances" or "Because I only run the best". At least your decision, as well as a select few others, has solid reasoning behind it. For those that run W2W/endurance racing or run a bazillion WHP, I could see how AMSOIL could be a necessity. At that level, I'm not sure even I'd trust testing out oils.
At least it's actually a decent oil so people using it should never have a negative experience. I've never heard anyone be disappointed in AMSOIL. It's like using a Rolls Royce to go to the grocery store.

 

 

Same here. Or, rather, "same level of protection required by my engine". I just don't like waste, be it money or otherwise.

 

 

I'm curious about this as well. I will be sending in a sample to Blackstone soon, from my car that runs e85 only and using brad penn 10w 30 after 3k mile interval. I would like to see others results of E only cars.

 

Lol watching Street Outlaws listening to them trashing their bearings from too much ethanol in the oil made me think about this thread lol.

 

Lol love that show. Do you run e85 only?

 

 

lol I'm assuming it's a built block that sees a lot of race time? I've decided I'm not gonna risk it after I put on the FP red and just go with full synthetic VR1, then send a sample after 3k. If I spun a bearing running Brad penn + E85 I would blame myself big time. Not gonna risk it.

 

I have used Rotella T6 5-40 over the years in 4 different vehicles including my Evo. Recently there has been a formulation change by Shell and there is some argument whether this is a good or bad thing. The Evo has never used any oil between changes, so there is no difference. On two high mileage BMW's and an old Land Rover Disco there is definitely decreased oil consumption between oil changes. FWIW.

 

Same here. The change has me concerned as I can't find any info on exactly what changed. I've only heard rumor is not as good, now. I swapped to Castrol this time, though, to see if I can cure lifter tick (two sets of lifters. still tick. Checking rockers next time). I notice the Rotella has a pretty strong e85 smell when I change it (every other track day, plus some in town driving). If the Castrol has the same smell, I'll go back to Rotella. I've used T6 since about 2010 (I think) and have had zero problems. I love the stuff. Or I did before the "change". We'll have to wait and see.

 

I've always been curious about sending in a sample. Used Amsoil Dominator for the longest time but switched to synthetic VR1 a year ago since it's ridiculously cheaper. Car feels like it runs just as good but don't have any actual evidence to back it up.
