Best oil for the 86
 

I know this has been answered numerous times and I have searched on this and Bob is the oil guy forums

But what I want to know is
Simply which is the better oil for our cars
I have used rp not in the 86 in am Mr2 and it loved it

I'm using penrite ten tenths 0-20 racing oil

I have come to the conclusion it's best to use 0-20 according to bob is the oil etc

But
Is royal purple good I mean the api stuff
As it's a fresh motor 5K kms on it
And the royal purple says it may void warranty if you use the hps grade or the xpr

Now the car sees a fair amount of track work and the way I understand it the Sn and sl api grades tend to sheer down quite badly

So is there any UOA on different brands of oil with our cars to determine the better quality?


Anyone got links to voa or UOA for our cars using
Valvoline
Motul
Royal purple
Penrite
Etc

No flamers please
And please provide evidence if your going to bag another brand over another


I'm tossing up between
Valvoline syn power or the vr1 but it doesn't come in the 0-20 so probably not the vr1
Or the royal purple api or hps/ xpr

Just not sure if I should risk the warranty over oil or not but for the added protection on the track it might be worth the risk
Unless the api stuff will hold up ok


Hopefully bluesubie has some input as he seems to have a good understanding

I want the best oil for quality and protection and performance

Thanks guys :)

TGMO for me, I have a few good UOAs from hard track duty.

*also this should be in the Mechanical Maintenance section*

Sorry all the threads I looked at only asked the question between two oils then got really off topic
I hate to be that guy to make a new thread ahaha

Did you want to post them up or link me them

It's interesting you use the stock standard stuff
When those api Sn products tend to sheer down quickly

Very interesting

Sure, here is one from about 4 hours of track time (and about 600 road miles) before I had an oil cooler (which means oil temps probably in the 290 degree range)

Copper was only 1 ppm high, which is pretty standard for these cars (think mine had about 6K miles at this point) and I did have a small intake leak which increased the silicon.

Yeah right interesting

Anyone got any more info
To which oil seems the better quality for protection and performance

Thabks decay :)

Anyone else
I'm sure theres people who have an opinion or some reason why they use one over the other

Anyone using Valvoline syn or royal purple??

My impression is that it is more important to change the oil regularly than the brand of oil used. That is not to say that some oils hold up better over time but if one is changing the oil sooner rather than later then the oil doesn't have time too start breaking down. My car approx 27k kilometers, 6 oil and filter changes. Diff and gearbox at 21k kms.

Yeah I have heard that aswell

What kind of oil are you using out of curiosity and what grade

As the sticky in the PCMO forum at bitog says, "There is no BEST oil!".

For the street, flip a coin an use any API SN/GF5 0W-20 oil. Be careful what you read at bitog though. Motor Oil University was written by a plastic surgeon and some people in the industry say it has a lot of errors.

Neither Valvoline VR1 nor RP HPS are API certified, but I would probably go with RP HPS 5W-20 if I hit the track. These cars see high oil temps at the track. There was actually a recent very funny thread about which oil to run in the 86 (well one of the last responses was funny). "Cujet" FTW!

:bonk:

If you consider the mileage on your oil (1,000 miles) against the universal averages (2,500), your copper is actually higher than that.

Aftermarket intake?

If someone has a link to that thread I'd be greatly appreciated

Also
What's penzoil ultra platnium like??

Is that good woild that be a good oil
The only real way is to do UOA testing
But thought I could start near the top ahaha

So the api royal purple Is good for the street
Or the Penzoil better

Is the 5w going to give best cold engine protection

Yeah, but considering the engine mileage, this is still in line with quite a few people who had copper PPMs in the mid-high 20s until well after 10000 miles.

Likely still break in, I'll report back after I get my current UOA from this past summer.

At the time of this reading I was using a Greddy intake.

Can I use 5w 20 penzoil ultra platnium I cannot find anyone who has something bad to say about it
Or am I better finding a 0-20/0-30?
Amazon has the 5-20 for 35 a jug :0

Yes you can use 5w20 pennzoil ultra platnium PurePlus Technology, in fact, im using it on my car now. No problem so far and run smooth.

Awesome was just making sure it may cold start protect it too as I knkw it should be 0-20

I guess a UOA will tell me the best really

I like Eneos Sustina 0W-20 although my next fill will be Joe Gibbs FR20.

I have never heard of that either or them will look them up
Thanks man :)

Ok I have almost
Decided

Royal purple
Penzoil ultra platnium
Tgmo
Or
Penrite ten Tenths/valvoline

Which would be the better oil

Cujo for the win. Right. A vague reference to the glory days of Daytona in the '70s and y'all are convinced.

They never even heard of Herr Fischer or Herr Tropsch. They were stuck in the '70s. Are we really comparing son of flubber to polymethacrylates?

I do hope that no one is taking these beautifully balanced 86 machines, adding aftermarket enhancements, and then going out to the track and redlining on TGMO.

Thick oil people are so thick. At least I got bluesubie down to HPS 5W20. :D

Amsoil Signature Series 100% Synthetic 0W-20 👍 I believe in the "there is no BEST oil' statement, but I can tell you this is a very very very good oil, and all I'll ever run in my car 👌 I'd chose it over any of the other suggestions

So what makes the 5-20 better then the 0-20 as they would both be just as thick once heated
Or close enough
I'd understand 0-30

I am really leaning towards the Penzoil just wondering if that's a good oil?
Or would the Amsoil be better

Or would a 0-30 be. Better suited to aussie conditions and driving the car hard

I'll never track my car, it's a daily driver for me. I'm more interested in why Subaru specifies a 0w20 for this engine. My last subie was a 2.5 NA in my 2006 legacy, and the compression on that engine was obviously lower than this one and it used 5w30. It would seem to me that this thinner oil might not protect as well, and might slip past the oils control rings more easily.

Simple answer = clearances.

That's right
The clearances are Alot tighter
I'm happy to stay with. 0-20
Just thought maybe for hard driving and hot aussie conditions a 0-30 may be more suitable
I guess a UOA will best tell me tbh

Lol i run amsoil 10w-30 on mine

Done any UOA
Does it burn any etc how does the car run like Alot better etc

Personally I'd just stick with the recommended weight, I've read threads where track cars run thicker oil due to what their being put through regularly,
But the recommended weight and an oil cooler (to help keep it in normal operating temps and reduce thinning a bit if you're really worried) would be more than what you need for hard street driving, and be fine for even weekend tracking,
M car has 40k KM on it now, and I've never noticed any oil consumption, as for UOA I haven't done any, I forgot to sample during my last oil change or I'd have something for you. There was another thread though where someone did get a UOA for the Amsoil 100% Synthetic and the results were really good.

For comparison I used Amsoil in my VW TDI religiously, (the Germans are very picky about their oils performance) and it ran soooo much smoother, and quieter, you could literally feel and hear the difference Amsoil made in that car, 20k KM change intervals and the engine never skipped a beat,

I just highly recommend amsoil in general, currently using their engine, transmission, and differential fluids 👍

Here is a Miller Nanodrive UOA. Me and few other members have been running this and we seem to like it.

Really appreciate all input hey
I think I may give the Amsoil a crack and see how that fairs
:) of anyone has any more UOAs or opinions would love to hear them
Might stay with a 0-20 and go off the UOA trends

You have answered your own question.

:D I'm a firm believer in tuning the oil for the application!

Because a 5W-20 is usually a more stable oil due to less viscosity modifiers. If you compare NOACK volatility (evaporation), a 5W-20 usually has a lower NOACK than the same brand's 0W-20. Amsoil is one brand that lists NOACK. Amsoil XL 5W-20 = 9.9% NOACK and XL 0W-20 = 12.5% NOACK.

For 0W-30, it depends on the specs it meets. If it has a low HTHS of less than 3.5, the same applies and it will sometimes shear to a 20 grade in harsh conditions. The exception is a 0W-30 that meets ACEA A3 specs because those oils are designed for shear stability over fuel economy.

The only advantage that a 0W-20 will give you is that it passes the cold cranking viscosity test at -35C as opposed to -30C that the 5W-20 passes and gives you probably .5% improvement in fuel economy in temps below freezing for the first 10 minutes of driving. In severe conditions, I look at NOACK, HTHS, anti-wear/detergent additive package, and kinematic viscosity at 100C.

@ bluesubie - lets tune the oil for the D/D E85 application - Your recommendation ? (sorry if you've been asked this a hundred times)

So seems like 5-20 is the way to go for now anyway
Guess I'll do a UOA and compare :)

LULZ. bluesubie, I see you have traded out your beloved Motul for Pennzoil Ultra Euro 5W40 in your ancient, beloved TurboForester. Very interesting.

As I approach 300k miles, I am admittedly looking at 5W30 Pento Superformance III or Liquimoly Top Tec 4200 5W30.

Why? These are both VW 507.00, with the highest level of piston cleanliness required. Also I am merely spec'd for SM 5W30. Piston cleanliness has been my issue in the past.

OP, Amsoil Signature Series 5W20 and Pennzoil Platinum Ultra w/Pure Plus 5W20 are very good motor oils.

Yes, there are a few E85 threads posted here. Mobil1 has actually recommended their Turbo Diesel Truck 5W-40 in E85 applications originally calling for xW-20. That's stuff is thicker than RT6 though so I don't know about that.

There's a pretty wide variety of E85 uoa results posted here as well (very good and not so good), probably reflecting the wide variety of tunes. Not knowing anything about your specific application, I'd probably go with Red Line or Motul 300V xW-20, or Pennzoil Ultra 10W-30.

Hey stalker!

That run on Motul X-Cess 5W-40 was after I saw a very long oci from a Stage IV WRX uoa posted on bitog (~8,000 miles IIRC) and picked some up from my buddies at AZP Installs. A lot of prior runs on Motul were purchased with Subaru bucks (Subaru Mastercard rewards), but that program is dead now so no more free oil.

Running ancient API SM PU 5W-40 in my ancient Foz because Pennzoil was good to me and sent me free oil in the past. I'm not brand loyal though and have run many different brands; Motul, Pennzoil, Castrol, Amsoil lots of different Mobil1's, Red Line, etc. I change my mind every two weeks about what oil I want to run next.
:cheers:

10 w 30 amsoil dominator at 450 ish whp no issues approaching 5, 000 mike oil change interval with over 12,000 miles of dd at that whp and UOA. I've posted them in a few of the oil threads.

Good job !
You have the sickness.
Friendly stalker here.
It's lonely being banned on bitog.
I respect and enjoy your posts.
