Engine oil RED LINE or Pentosin

4 qts Redline 5w40, 1 qt Redline w40 Race Redline blows away the competition... Lumps of ZDDP and Moly with the Race oil mix, fuel dilution pretty much disappeared, and viscosity/flashpoint are well within reason.

I would stick with a tested oil like Red Line 5w-40 or GC, but that's me.

Sticking with a single weight is a better idea than mixology IMO..

Thanks for selling me the last two bottles of Pentosin!

I have been running redline 5W40 since 5k miles in my 08 GTI and I noticed an immediate improvement in turbo spool up. Others have noticed this improvement on other turbo cars as well.

Pentosin High Performance is the right one to use. 5w-40 Pento High Performance 5W-40 is an especially formulated fuel economy engine oil. It is based on synthetic base oils only, the most modern and best engine oil additives currently available and a very shear stable VI - Improver. The combination of these exquisite components guarantees an excellent engine performance under the most severe driving conditions. Pento High Performance 5W-40 is ideally suited as an all season engine oil. Pento High Performance 5W-40 contains a special combination of very efficient fric-tion modifiers which cause the engine to run very smoothly. Even more important, it causes fuel savings in a recognizable way.

I would stick with oils like PENTOSIN/LUBRO-MOLY/CASTROL GERMAN/MOTUL/ This one is easy. Anything not made in the US and is 100% synthetic. I use Pentosin high performance 5w-40, 502/501/500 approved oil.

I am planning on using redline 5W40 which is not on the vw approved list but has an awesome HTHS viscosity and I have used it in my boxster S with big improvements over M10w40.

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.

I've been running Redline or Royal Purple 40wt
