What oil?

[IamFODI]

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 ?

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

Yes, it still shears from what I read, but not as much as it used to like 15 years ago is my impression. It also is fairly light to begin with, for a 60 weight.



What about what? I wouldn't run a 5w40.

I just find it interesting on Bimmerworld that they recommend it for Cold Temps in S54

Motul 10w60.

Ran German Castrol 0w40 with no issues for many years, since I was running it on my E38 as well, I gave it a try. Engine temps were always cool. Never tracked but driven hard.

liqui moly 10-60, used on my track duty E60 M5 also.

[Tbonem3]

In what sense?

I know it used to shear down into the xW-40 range in service. Does it still? I remember doing some digging on this a few years ago and came to the conclusion that (then-)current formulations basically never sheared past the xW-50 range (min. 16.3 cSt @ 100º C).

Yes, it still shears from what I read, but not as much as it used to like 15 years ago is my impression. It also is fairly light to begin with, for a 60 weight.

What about 5W40 vs 10W60 then?

*PSA*

Talking about oil weights by using terms like 5w50 or 10w60 is almost useless. Just like tires - A 265 Michelin PS4S can be wider than some ling ling 275 tire.

Castrol TWS is called a 10w60, but it acts like a heavy duty 40 weight from my research. Then there's something like Liqui-moly 10w60 with a CST of 26+ at 100degress, which is about the highest I've ever seen, much higher than castrol or other 10w60s.

The "redline 5w50 instead of castrol 10w60" argument for S54/s65/s85 has gotten popular, but is redline lighter than castrol?

Well, 1st formula of redline had HTHSV rating of 5.9, newer formula is 5.0. Castrol is 5.3! Barely any difference. "ReDlInE is bEtTer in the CoLd!" Well, RL 5w50 has a cold pour of -45 and Castrol's is -39 so no.

Viscosity, Kinematic 100°C of Redline is 21, Castrol is 22.7, almost no difference.

You cannot conclude that redline is better for cold starts than Castrol just because Redline says 5w50 on the bottle and Castrol says 10w60.

Haven't even discussed additives. Perhaps Redline is low on additives because their product is meant for race cars. So even if redline and castrol were neck and neck in terms of viscosity and resulting oil pressure etc, Castrol could still be a better choice for most (Street cars) due to better/more additives.

Or maybe you have cats and don't want a race oil high in ZDDP? Castrol has other anti-wear properties that don't damage cats.

What about 5W40 vs 10W60 then?
