Engine oil AMSOIL or Pentosin

pentosin/pentosynth 5W40 here, changed it 1K miles ago (second run on this oil), great stuff ecstuning.com sell it for ~28 bucks for 5 liter. I like it much, much more over the castrol from dealership (used that too and after 2K miles changed back to pentsynth). I'm very happy with it.

0w-40 weight oil is great for the VR6. I've been using either Mobil 1 or AMS European Formula (5w-40) in mine since day 1. 85k miles later it still runs like a champ. AMS Euro oil is fantastic stuff, definitly worth every penny.

i used their oil before and was very happy.

I use Amsoil full synthetic 15w-40 year round in my 1.6D with over 250k miles.

Amsoil 20w50 in my 8-v 12:1+ 1.8 liter Rabbit Amsoil 5w-40 in my street turbo Jetta and track turbo Golf.

I switched to amsoil 20w50 and the temps are down to 230ish

With the AMS and a 20 row cooler my temps stick at 190-200 dependant on ambient temps thus far.

Stick with the synthetic. The tiny turbos on the TDI's are heavily stressed and mineral oils are just not up to the task of protecting the bearings in the turbo.

amsoil here too, right now 5w30 going to switch to 0w30 soon, best stuff for the $$$

Amsoil 10-30 my dad's an amsoil dealer
