Respsol possibly the best full synthetic ive used Its Repsol full synthetic race oil what more is there to say except the Moto GP and AMA riders use it! March 24, 2014
Rated API SM This oil is rated API SM not SJ as indicated on the web page. SM is a newer American Petroleum Institute (API) standard. October 23, 2013
Great Oil I'm about 5000km into the oil and it is still as smooth as the first day. October 7, 2013
Great Oil! I switched to synthetic oil on my Gsxr 1000 about 7k miles ago and I've been real happy with Repsol since. My bike shifted noticeably smoother and felt more proper going through all the gears, under hard riding and casual alike. I would certainly recommend this product! August 12, 2013

Rodger J asked: I'm looking to try out Repsol full-synthetic for my 848 Evo. I don't track my bike and it's not much of a commuter either (a couple of days a week). I ride her decently hard here and there, but nothing really overly dramatic. Is the Racing 4T overkill? I'm most concerned what's best overall. Aug 9, 2013
