Well, Amsoil seems to be very popular. What about Maxima Castor 927? I was told it was good.
Trying to decide which oil to start running in new bike. I like to start off with a good oil and stick with it.
the maxima does work well. With the Castor/Benol oils, you need to be an A or AA rider. The ones that keep the gas pinned will benefit the most. I agree with running the synthetics for the average guys.
I have always tried to run company's products that I know support our sport the most. For years I ran the Klotz oils which worked well and smell the best IMO but mainly because they always had a support trailer at most of the races and would be title sponsor of some.
Times have changed now and other companies are stepping up and so has my oil choices. Don't know if there is any oil out of the big companies that is really better than the other, you just find what you like and want the best and run it. I just try to support the ones who support our passion to ride and race.
