I have been looking for the thread that tells aouut sending the oil out to be tested. If anyone can point me in the right direction it would be very nice. thanks guys.
I've been testing to see how far I can prolong the oil life in my Cadillac. Mobil 1 is expensive, and so far they are recommending a oil change interval of 10,000 miles. I wouldn't go that far on a bike, but you could extend over what the factory recommends.
