Anyone running this stuff? I had their rep come in today, my price is good for full syn "racing oil". Not sure how race it is since it has detergent and rust inhibitors in it... But they say it outperforms everything... Which is also a likely story lol. Just curious if anyone has any real world experience with it. They only make 10w30 and 5w50 in the race oil, well besides all the sae stuff and 20w50 anyways. No 5w40 besides their diesel full syn, and only 5w30 in the euro syn.
