Imagine how much effort it must take to clean this oil enough to put in our motorcycles.

Anyway, back to work now.

I used to think about getting fancy with my oil changes, but I have a tough time finding synthetic oils that don't have a bunch of additives. In addition, I could never seem to find the correct grade numbers in synthetic oil. The motorcycle specific synthetic oils seem so expensive. So I eventually just decided to go with what the owner’s manual recommends. Now I just use Castrol GTX 10W40. It is cheap and easy to find. I figure that frequent changes of cheaper oil, is better than less frequent changes of expensive oil. Besides, all the oils have to meet certain standards. I suspect that we are talking about the last 5% between the various oils.

Why don't we ever talk about which brand of gasoline to use? In reality Shell gasoline may have come from an Imperial Oil refinery or vise versa. They trade the stuff back and forth all the time. I suspect motor oil it the same story. The oil all originates from the same place, at least when we are talking dino oil.
