Engine oil LIQUI MOLY or Shell

I use Rotella 15W40 in my BMW. It is good stuff.

Thanks for updating, it is nice to see a progression like that. A full history through 25k miles and things look pretty good on the Rotella T6.

I have only used Lubromoly/Liquimoly 5w-30 Full synthetic with the Mos2 Additive. Molydenum sulfide from liquimoly and my car runs super quiet and idle very smooth. I change my oil every 2500 miles..no matter what. Oil pressure is very good, zero shavings in the oil between oil changes. Additionally, I use the liquimoly engine clean between changes and like I mentioned before the car runs superb...no complaints here.

They were using the wrong oil- Shell 0-30, and it was clicking pretty loud when cold. I got the oil change kit from Duetche Auto and put in the Luqimoly. What a difference. I cant recommend it more. You will love it.

Right now I run 15w-40 Shell Rotella Diesel engine oil in my bug. You can see below the Zinc & Phosphorus PPM (the higher the better). So you can see that Shell Rottela & Napa Diesel oil has fantastic for wear protection for the aircooled flat tappet cams.

I use Shell Helix 10W-30 for my Sciroccos. No probs! :thumbup: I always have a 60 litres barrel in my garage for my cars.

From what I've seen, the t6 holds up well, doesn't shear quickly, does well with fuel dilution, protects surfaces well, since the metal readings go down, etc. I don't see any negatives, regardless of what that article says

Rotella T6 is great oil (lots of STI guys run it) and I wouldn't hesitate running it in my R... except that it isn't VW 502 approved... so warranty is at risk if I had a failure in the engine.

The biggest advantage is that it's CHEAP and works well. I don't run it in my R...yet. I am still under maintenance free. I do run it in my Stage 3 B5 S4 and in my 1991 Audi 200 though. Haven't sent the oil to Blackstone for analysis, but haven't had any issues either.

Personally, i like the Lubro Molly stuff the best. While not too relevant to the MKVI and the TSI engine, when I used it on my former MKV with the FSI engine, I definetly noticed a lot less oil residue on my tailpipes and the engine just felt better, smoother and quieter.
