heres a lil discussion on car oils from 2007 hope it helps
Mobil 1 has apparently actually changed the formulation (all weights) of its fully synthetic car oil we have been using for years….. In the past, they only changed the label, but the product worked well. We have had a rash of welded clutch pusher assemblies (and damaged clutches) in the first part of 2007. Nearly all can be traced to switching to the “new” Mobil 1.
Our 2007 Oil advice at this point (in order):
1. We use our Alisyn <<0 in all of our stock engine bikes. I will be testing a thicker version for general street and big power use very soon. (<<0 has been in my ZX-14 its whole life, and it just made 195 HP last week- one of my friends has had it in his GSX-R1000 for 11K street miles, and he also road races the bike. This oil is the best we have ever found!)
2. Quaker state 20w-50 (Big CC/Nitrous) or 10w-30 (stock) is organic…..but it works VERY well and is readily available.
3. Find the highest quality, fully synthetic MOTORCYCLE oil you can; Royal Purple, Red Line, Amsoil, Golden Spectro….etc. We have also had very good results with Motul and Motorex in the past. (BUT- we just had one customer have a clutch pusher weld problem switching to Motorex from Red Line- switched back to Red Line after the repair and the problem went away…so we are as confused as you at the moment about this problem.)
4. ANY fully synthetic motor oil from ANY motorcycle manufacturer/Dealership (Suzuki, Honda, Kawasaki, Yamaha….etc.) will also be a fine choice.
Note: We try to stay away from all other synthetic car oils as a result of customer problems in the past (Castrol, Kendall, Pennzoil etc. have all caused problems of some type). The organic versions of these brands have also been in question for years...but hell- everything changes and at this point…use your own judgment!
