Anyone uses Liqui Molly 10w60?

[DimrBimmer]

I am typically put Castrol TWS 10w60 into my almost 60K S54 engine. I found a mechanic to do some work on the motor (rod bearings). He is a bimmer guy too and tracks his cars. He swears by Liqui Molly 10w60. Just curious if anyone using it in our engines? My car is mainly used for pleasure, but some performance driving school action too.

Does it really matter what oil is used? When I bought my used Z3 from a dealer, he changed the oil with BMW mineral 15W-40. After that I have been using Mobil 1 0W-40. In 15 years of forums for three very different cars, I have never heard of any oil-related problem. All the engines run fine until they run out of oil.

If you're running an S54, oil is much more critical. There were very specific requirements due to the RPM and rod bearing design. The Castrol TWS 10w60 allegedly met all of them. The specs for most other 10w60 oils are different. I'm not conversant enough to know what issues are critical, so I've stuck with the Castrol in my S54, which doesn't consume any oil at 104K miles, and the original rod bearing were in good condition when I replaced them recently. Hopefully someone who has actually used an alternate oil will check in with their experience.

I am going to let Randy and alike to argue about oil quality. I guess it could be olive oil as long as it keeps its viscosity. As non-mechanic, I have to rely on google university and this forum to select what mostly recommended by the pros in business. I believe the argument here is, when you open up an engine and it looks like new, you used quality oil. The opposite of the spectrum is all brown burned sludge... I believe Randy Forbes talked about that in one of the posts that I can not find at the moment.

So quickly an oil thread has devolved to olive oil ;-)

Could have been worse, Peanut oil. Although peanut oil does have higher smoke point.

Peanut oil is much more preferable to olive oil. This is based on highly selective back to back google searches.

(Full disclosure, I live in the self-proclaimed peanut capital of the world)


I stock the LM- 10W60. I used it in my own boosted S52 until I installed an oil-cooler. No complaints.

I've run the LM 10w-60 in my Moto Guzzis for years and it does a great job. Will be using it in my 2.5i at the next change. BMW calls for this weight and that it's synthetic. I suspect the engineers know more than me so I follow the manual and use the 10w-60.

And don't trust dealers to know or give a crap. When I bought my first Guzzi they had filled the engine with 10W-30 dino juice since the service thought 'it's all the same stuff'. Almost ruined the engine before I even got it home.

Ive run it on S54 and S62s for awhile... No problems. Pretty long history of e46 m3 guys using it

[TexaZ3]

LM RT GT1 10w60 is a fine oil to use in S54. Have been running it in 3 of my E46Ms, my E39 M5, and my E63 M6. No problems thus far. Oil consumption in my S85 decreased from about a quart per 1500 miles to about a quart every 2000 miles after switching to LM from Castrol.

Blackstone reports continue to be stellar, though, at the end of the cycle (I usually go about 7-7500 miles on oil) viscosity numbers are slightly lower with LM, but not significantly so and still within acceptable range. Overall, for the price, I'm sticking with it until I find something better.

I use the LM 10w60 in my father's 01 S54. Has around ~150k on original rod bearings with no issues. Been using the LM since about 85k. Another local group member uses the LM in his 02 S54, no issues. Not sure on mileage since he's on his 3rd engine... Nothing LM or oil related though. (hydro-lock)

Thank you all!
I guess I don’t need to fight my mechanic on oil choice.
