Owner reviews for engine oil

I run Motul in my 05' GLI and its amazing. Motul doesnt break down like other oils its good stuff

I use 5w-40 Castrol Syntec without any issues.

I run VW. 502 Lubra-moly 5w-40 that my local NAPA special orders for me.

5w40 pentosin vw 502.00+ oil. Hasn't let me down in any of my motors yet!

I use Mobil 1 full synthetic(type 4)20w50 in the summer and 10w40 in the winter(we range on temps here widely, hence the change in oil viscosity by the season).

I use Mobil1 0W-40 on a 149K motor.

I use motul 5-30, great oil.

Edge worked great for me. Maybe the best oil on the market.

I use Rotella 5-w40. I've been using it for like 5 years in my 02 1.8t and haven't noticed any wear really at all. I drive pretty aggressive, redline 3+ times a day.

I've used 0W40 Mobil 1 Full Synthetic from the beginning. I have Blackstone Labs constantly analyze my oil. It started with several 5k mile analysis and then I upped it to every 7.5k miles. The oil analysis came back very healthy on all 5k and 7.5k mile analysis, and led me to up it once more to every 10k oil change interval which it will remain. I use the larger Passat 1.8T oil filter. The engine has almost 170k miles on it and still running strong.
