Hi guys. Been a reader here for years but this is my first post. I am looking for some advice on course of action. I have a Kawie ATV that I ran dino oil in for the first 1100 miles. Never leaked or seeped a drop with that oil. Then I switched over to Amsoil 10w-40 Motorcycle oil, and within 100 miles, it started creating wet spots all over the engine. When I called Kawie, they blamed the oil. When I called Amsoil, they blamed Kawie. I tend to think it's more the oil because I have a hard time believing that all my seals and o-rings went bad all at once. Seems more likely that the oil is the culprit even though Amsoil claims that their oil has seal rejuvenation additives and does not "find all the holes and seams to leak from". Whatever the case, I want it to stop. I love what Amsoil does for the inside of my engine, but I hate having all these leaks. I don't mind that my engine seems to burn Amsoil, but it drives me crazy having my engine look like a 50's era 2 stroke with all the stains on it. So my questions are these: Should I go back to dino oil? Is there a synthetic oil that doesn't leak so bad? Should I try some Lucas Engine Oil Stop Leak or something? What are your experiences with Amsoil? Have you had this problem with it? Thanks in advance guys.
