Best oil for the 86

Hey Dennis,

Yep she's a stocky running shivs E85 tune and his OFH going in soon. Would like to think that a grp 4/5 20 weight oil would suffice. It's a dd and has an easy life, 60-70% freeway, very little idling, a few spirited drives, gets min 30 min twice a day, oil gets to 100C within last 10-15min of drive, no freezing temps, decent summers. My recent UOA's look promising although it's early days, there are more coming. Fuel dilution could be an issue, both kV & TBN looks good on 0W20 on this fuel. Amsoil has been highly recommended I see, I like 300V 0W20 also but will it be OK for an extended period like 3125K miles ?

Cheers buddy,

Doesn't the Aussie manual specifically allow 5W-30? Our manuals don't define an additional viscosity but do state that a thicker viscosity might be a better choice under heavy loads. Having said that, 3.7 is fairly robust and will behave more like an xW-40 in the bearings.

In all likelihood, there's a very good chance that Dominator doesn't use any VII's which is the reason for the low VI.

Oh, you're in Oz too? Yes, Motul is fine for 3,125 miles (if that's what you mean). No Pennzoil Ultra there. The group V racing xW-20 oils usually do hold up better, without the need for going to a 30 weight.

I'm even tempted to try Rotella and change it more often considering it's price.

Loving them comments, sounds good to me The Aussie manual states 0W20 as the oil of choice but also states another as you mentioned - 5W30, but only till the next service after which it should be changed back to 0W20. Not sure if it's fuel economy driven or engine design, I'd be inclined to think a bit of both. I'm also inclined to stick with the lighter weight provided it stays in grade as it should perform better than the heavier alternative.

^^ AGREED

ALSO
There is a Australian amsoil distributor
16$ a quart for the signature series
You could also purchase it direct off the Amsoil website
That's us based
For a little cheaper
But then your up for shipping etc

I will start using 5-20 amsoil signature series frombmy next oil change on

Have only done 1900kms on current penrite ten tenths
I'm not running E85 yet
So will wait untill about 5500-6500 and then dump it

[EthsTornadoGTS]

Will be doing a UOA on penrite in another 600kms then again at service

I have used Subaru 0w20 / Eneos Sustina 0w20 / Toyota 0w20...my favorite is Toyota's 0w20. I have also sent all my oil samples off to the lab.

Please elaborate on your preferences and post your uoa data !! I will read and study with great interest.

TGMO, your fav, is being bagged upon right now over at thick-sick headquarters on bitog. As usual, the only one getting at the truth is Gohkan. He has actually used TGMO for many miles, in an older Corolla.

A lot of self annoited experts over there who grease themselves up with thick oil are stating their case. They are bonifide, yet myopic. This is strange coming from intelligent people with scientific and mechanical backgrounds.

Why are thin oils back spec'd? Why does Toyota spec TGMO for the Prius and the Tacoma? And the NX 2.0T ?

What don't they like about TGMO @ bitog?

[MikeyBatz]

I got Eneos 0w-20 right now and very happy with it. Gained 2-3 MPG as well.

It's the one man, caterham, who started the TGMO craze. That's who they don't like. They say that TGMO is too thin.

What do your UOA's tell you, tbrocato? There's where the truth is. Several consecutive UOA's will establish trends. You are correct, sir. TGMO it is.

Here is my list of thin to relatively thin oils I have used, all 0W20 SN/GF5 except RL.
RedLine. Sustina. TGMO. MGMO. Amsoil SS. Kendall GT-1 Blend. PP (old) PPPP (new). Edge Black Bottle. Edge Gold Bottle. Mobil 1 AFE. Chevron. ServicePro. ProLine.

Two and one half years, two hundred sixty seven thousand miles of hard driving in a vehicle spec'd for 5W20 SM. There is no oil consumption. My PCV valves are pristine when I replace them after 100k miles.

Again, I ask anyone to explain to me, why is TGMO spec'd for both Prius and Tacoma-and the 86? I purchased a 2005 Tacoma, spec'd for 5W30 SL. I totalled it at 671,000 miles. The exact same engine, Tacoma 2015 spec'd TGMO.

Don't even think twice tbrocato. You know you are right.

I really can not answer your question on why they went with the 0w20...I am going to be sending in a UOA to blackstone when I get back inshore of TGMO. I just also realized I have not changed my oil for a little over 1 year....this was def. not on purpose.... kicking myself in the ass on that right now. I only have around 7k miles on this last oil. Hopefully nothing is damaged with going that long since my last oil change...we shall see.

Aahhh. I see.
Thanks for harvesting petroleum for us all.
Two concerns. Fuel dilution and corrosion.
Pay BS extra for TAN and TBN.
You'll be fine.
Change the oil very soon.
Your car sits. on the Gulf Coast. with prolly few highway miles.
Maybe a 5k OCI is a good idea.

TGMO, and other 20 grades, is too thin for some conditions like the track.
