whats wrong with yamalube 4. my last 13 bikes all used 20-50 castrol gtx & never had oil related issues. rings, valve guides, engine ware all fine. i know theres alot better oils than gtx but come on $9 a quart is a total rip especially if youre changing it at 3,000mi
Well, I have used Mobil1 for the lastg 20 years. So for me there is no substitute !!! Also on my car it specifically says in the hood on a metal label, use Mobil1 synthetic 20W50 ONLY. so it must be good [8D]
Bis my vett said use mobil 1 also but it said that because Mobil 1 paid Chevy to put it there. I am with the change it often thing. Any oil that meats the latest API standards and good oil, sure some are better but 9 buck a quart? I would bet money that if a lab tested all the different mobil 1 oils nothing would be different other than the lable.
He Biz! I have been using Mobile one Syn for years in everything. Got tired of looling for the big twin. Eric has Amsoil for under $6.00. I really like it. Had to set the idle back and you can notice a big difference in the way the trans shifts.
