I put in some serious time reading up on oils for 1.8t, this is what I found and how I'd rank them.

..the other 4 (#2-5) above the SuperSyn, and what properties gave Chevron the almost top spot? Would not have considered Chevron oil very strongly prior to reading this.

Is it strictly based on its specs rather than user reviews/oil analyses?
Thanks!

as a starting point. (pun intended) The list appeared to have the favoured otc oils on it already, how could you go wrong? These oils were recommended by private testing as well as personal experiences. I arranged the order with as little presonal bias as possible. Admittedly, I had some info going into the research, mainly that M1 is not the best, and I could go into that specificly. It is simply over-rated by people who know that Group IV (M1) costs more than III to produce and resent paying the same for Group III BUT the punchline is other good otc III oils test better than M1 especially if you consider the hard deposit PAO IV issue. Also the 0w is for mpg but 5w is a better weight and the ACEA3/GF-4 spec means nearly no EP additives. Group III + state-of-the-art additives is best in a street car.

It is a benchmark, a "given" that the GT-1 is the best commercially available oil. Mostly it has a long racing history and is the choice not of techs, but of motorheads.
