Engine oil RED LINE or ELF

The zinc and phosphorus levels (ZDDP) is much higher in the redline. Iron per 1000 miles is much better. Viscosity retention and flashpoint are much better also.

I love red line, search for my UOAs... i've tried most of the top teir vw502 approved oils in the FSI (Motul xcess, motul specific, total energy), and they don't even come close to touching red line with regards to longevity / performance.

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..

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.

I currently use ELF Exellium NF, Motul is good too I was tempted to get it....you can also check out ECS Tuning, they sell Lubro Molly now, I think that's gonna be my next choice and I might stick with it. I've used Amsoil for about 20K miles and liked it too. Otherwise, you can't go wrong with Castrol Syntec 5w40 either, I've used it since new all the way till 60K miles.

I used ELF Excellium NF 5W40.

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.

I personnally use Elf and love it, best oil I ever used so far.
