Big fan of Castrol
Have been using it in my motorcycles for years.
Never had a bearing failure on any motorcycle I've owned.
Make sure that you use 0W or 5W-30 at least so you will have better lubrication during start up when the engine is cold and the oil doesn't flow as well as when it is warm. I always liked Valvoline oil but haven't used it in forever since switching to Mobil 1 synthetic. I was sold on the protection ability of synthetic years ago when I read about a huge study done on NY cabs that showed better engine protection and less wear with synthetic oil even when changing it every 15k-25k vs. 3k-5k for a regular oil. The filter was changed every 5k but that was all and the oil was topped off.:thumbsup:I am using whatever the Toyta dealer puts in right now. Is it each dealer's choice or is it standardized by Toyota? When I get out of warranty, I will use Valvolene 10W-30 at the Valvolene fast oil change place. Valvolene was recommended to me years ago by a Toyota dealer. I have never had oil consumption or engine problems related to oil, in a Toyota.
