What oil?

[bigjae46]

Was the head gasket failure accompanied by overheating? That could explain some of the brown staining (in addition to some of the 10k+ oil changes).

M3s are usually low mileage cars. If you consider time as well, 14 oil changes over 20 years? Need to change it at least every year. Shiet, my 2011 E90 M3 is almost 14 years old. About to get its 46th oil change.

Cheers man,

Was there any conclusions on the label change for Edge ? i can get this ordered in locally

They have had a few label changes. It is all the same 10W60.

Since you just had the cylinder head off, I'm guessing you had it cleaned by your machine shop. If that is the case, the head will not turn that dark gold color if you do the 7500 mile oil change interval.

After having the head off, and witnessing those brown stains, and rock hard seals, i am not convinced in using TT or Edge

If I saw brown stains and rock hard seals, I'd suspect overextended oil change intervals (too long for how the car was used) and/or not driving enough.

Why did you bump this thread? That’s so evil 😈

🤣

I Bumped it sorry man, i wasn't starting a new oil thread,

i can't find much 10W60 off the shelf here in Australia, It's all special orders or roll the dice online,
Penrite is easiest to source cause it's made here

Here is the 10 Tenths someone mentioned

Amsoil now has a 10W60 available.

if you're going to use Penrite why not use 10 tenths R 15W-50 or 10 tenths premium 10W-60?

IMO, it's pretty telling that Penrite won't claim more than LL-98 performance levels from those. At least the HPR 10 is claimed to be at LL-01 level – still not enough for the S54, but better than LL-98.

Those 10 Tenths oils seem to be formulated for motorcycles and some track/race cars, not street cars. I don't see the point. Even if they reduce wear vs. other oils, the reduction will be so slight you'll never notice. That may or may not come with increased friction (and thus heat, which – oops – might increase wear in bearings and rings). The only thing that's certain is that they'll accelerate poisoning of the cats.

What is consensus on this oil?
Typically most of the independent shops i went to used Liqui Molly, but my last oil change the indy shop used Amsoil. Still not sure what to expect, but all seems fine so far.
From what I heard, Amsoil is a really trusted brand.

My last 2 oil changes i sent for Blackstone oil analysis so ill see what comes back with Amsoil, when I change the oil again.

What about this oil for the street ?

Hard to tell from the spec sheet, but I don't see anything to recommend it over any other decent xW-50 or xW-60 synthetic. Certainly wouldn't prefer it to BMW's recommended oil.

I just use whatever they recommend at my local jiffy lube
