big topic.....
....The issue of oil preferences is vast and endless. As bukeye already mentioned, many folks use Rotella. I am one of those folks. But not to say it is so superior.....I change my oil all the time.
One of the top mechanics in our industry was interviewed about many things, one of them being oil preference.....His response was, " If you are going to change you oil after every ride, there is no reason to use synthetic oil.... You are replacing the old oil before you have time to realize the advantage of synthetic oil." ...If you want to leave your oil in your bike for a while, which I highly discourage, then by all means use synthetic oil.....Rotella is 10.00 a gallon....4 oil changes for 10.00? THere is just no reason to leave it in for longer than a few hours of riding, in my opinion. Now in my two stroke bikes, we use synthetic premix exclusively, as it runs much cleaner, and can be mixed at a lower ratio, which keeps the power valve much cleaner in the long run.
