is 15w-40 ok to run in my mojave? just wanted to make sure before i change it.

 

15w-40 is ok as long as it doesn't contain Moly. Moly and wet clutches don't work good. Go to http://bobistheoilguy.com and read the specs on the oils....See if the 15w-40 you want to use has Moly.

BTW: Mobile-1 15w-50 is almost the same exact product as their 10w-40 bike oil but much ceaper.
