I've been reading and searching and I know I still have a lot to learn but I'd like to get something started with the great ppl on this forum I have a 2006 VW GTI with the FSI 2.0T engine. I've been running M1 0-W40 since I purchased it around 10k miles with 5k OCI. I've been modifying it over the years and last fall (53k miles) I stepped up to a bigger turbo (K04) to go along with the bigger injectors, intercooler, down pipe, etc, etc. Along with the turbo came 5 liters of Motul Specific 502/505 oil and that got me thinking about finding better / best oil for use with my boosted beast as I do tend to drive it hard often. I've had some problems searching on the site but I have some ideas and plan on doing an UOA on the Motul. I'm looking for threads, discussions, and recommendations on modified 2.0T FSIs for oils. I know this engine is tough on oil and don't mind paying for something high quality since I go 9-12 months before I hit 5k. I'd like to be able to pick it up locally but if I have to order online I can. So far I've gather to try some of these for a step up from the Mobil 1. Pennzoil Ultra 5w-40 Euro, Redline 5w-40, Amsoil 5w-40 Euro, or Rotella T6 5w-40. I'd like to know if there's any of these or others that can handle the abuse since I'm not really concerned with extending the OCI.
