E85 specific oil

[Reaper]

Well ill be boosted on e85 exclusively on the 19th and right now I'm leaning towards 5w 20 amsoil dominator after learning up a bit. I like its high zddp and since Subaru recomends a 5w30 for the fa20dit this heavier 20 makes me feel more comfortable than 40 rotella or tdt. I will post regular uoa, most likely blackstone. But has anyone used amsoils uoa?

It depends on the oil. Not the brand, but the additive pack, HTHS, and viscosity. Check the uoa thread. There are boosted and tracked cars running Red Line 0W-20 with very good uoa's. Most off the shelf 5W-30's (non Euro oils or non racing oils) sometimes shear to a thinner viscosity than some xW-20's.

I stopped using Blackstone because I kept finding so many mistakes in their uoa's and just because of the goofy comments. A turbo Outback owner posted an RT6 uoa at subaruoutback.org and the ZDDP levels came back lower than Resource Conserving 5W-30, which is impossible. I told him to contact BS and they said it was a equipment calibration problem. They re-tested his oil and it came back with 10-20% higher additive levels across the board. I've also spotted similar uoa errors at nasioc.

Oil Analyzer's Inc. (Amsoil's) is cheaper than BS (even with a non Amsoil discount) and it includes TBN, oxidation, and nitration. The only thing is that oxidation levels on ester based oils may read high and the lab may flag it as a problem when it's not. It's best to do your own virgin (unused) oil analysis, but the voa in the link above gives you a good view. Although oil formulations can sometimes change without notice.

Their uoa test methods are similar, but if you want to step above a uoa that is for more than entertainment purposes it'll cost a lot.
Many people go to Dyson if a Blackstone or UOA starts to show a major problem. Dyson helps you get to the root of a problem (BS just makes random comments) and helps you choose the best oil for your application. The amount of detail is just amazing (audio recording with your uoa).

I know there's a thread with a bunch of uoa's here, but I don't recall if there's one on E85.

Is there any truth to the claim that Dexos rated oil offers more protection in engines running E85?

The only 0W-20 oil I've found so far that's dexos-rated is Mobil-1's.. although the bottle itself doesn't have the dexos stamp of approval yet.

I've been running Amsoil's Signature Series 0W-20 oil exclusively since I've gone to E85 ~25K miles ago.. so far so good, but I don't track or autocross, just DD'ing with spirited backroads driving. And because of this, I'm probably going to switch to Mobil-1's 0W-20 now that my Amsoil supply has run out. It's cheaper than Amsoil, dexos-rated, and like you mentioned I can just change the oil more frequently.

That was released in 2011. I thought they had an e85 now

pennzoil 0w20 is dexos rated too.. so is castrol..

Thanks! Found a more comprehensive dexros list.. Pennzoil is on there, but Castrol 0W-20 isn't.

the edge will soon be on it.. says my castrol rep..

I'm not sure. I wouldn't believe anything that is pure marketing, like that web site. I couldn't find anything officially about it.

GF5 already has improvements over GF4 in regards to E85 rust protection and emulsion retention. Whether or not dexos adds anything to that I don't know. http://www.gf-5.com/the_story/performance/

dexos supposedly does offer better wear protection than GF5 alone according to this comparison tool. http://www.lubrizol.com/EngineOilAdd...l/default.html

Keep in mind that Amsoil Signature Series carries no formal dexos, API, or ILSAC certifications, although the XL and OE lines do carry API and ILSAC certs. Amsoil claims that XL 0W-20 exceeds dexos detergent specfications in regards to sulphated ash. If you want to see some GM/dexos bashing, just have a look at bobistheoilguy.com

That lubrizol site is very informative, thanks! Yea the more I read, the more basing I see against dexos.. I think I saw somewhere that says GM charges oil companies a substantial fee to get the dexos certification. Which might explain why some companies don't bother to get their oil dexos certified.

The GF-5 requirements are very reassuring. I think I'll just stick to the cheapest FULL synthetic 0W-20 GF-5 oil, and change my oil every 3-4K miles.

Looks like there's a new GF-6 standard coming out too.. just hope that doesn't skyrocket the cost of oil.

GF-6 has been pushed back a couple of times because there is some concern about 0W-16's providing adequate engine protection. Basically they have to design engines that will work with this oil.

The reason cited is delays in engine test development.

In a few years, the new BRZ owner's will be saying that 0W-20 is too thick and you have to run 0W-16.

Probably don't have it in US but

http://www.nulon.com.au/products/Ful.../#.UylKQM64PbI

Yep is 5w30 but it get hot here 100F + and if it gets much below 50F everyone would think the next ice age is coming.

Ambient temperatures shouldnt be the only way to judge what viscosity oil you run. Many people have raised concerns over tighter clearances in the engine leading to requirement of thinner oils. Also thicker oils tend to run hotter than a thinner one, its reduced flow leads to poorer cooling effect on critical engine components which is one of the oils main purposes. the Fa20 runs at around 95-100C, would a difference in ambient temperature from a "cold" 20C to a hot 40C really have a significant effect on oil temperatures(and hence viscosity)? you have to remember this car has no active oil cooling solution so oil temperatures arent directly proportional to ambient temps.

sorry for going slightly off topic

Boosted, E85.

What oils would you recommend and what change interval? I know you are not going to give me one, but give me a list to choose from... PLEASE

I've been running Motul X-lite 8100 0W-30 since boosted....

I find it interesting that Subaru does recommend 5w-30 for the FA20DIT engine. Would seem that for a boosted application that is the way to go (same internals both).

Ive been using Motul 300v 5w-30 and i have no issues at all

Today will be my 2nd Oil Change using this.

I do it every 5k miles


I love boost!!!!!!
