Been running polaris VES gold in mine. Dad used to run amsoil in his rev his ves valves were easier to clean than mine were I had to scrape quite a bit to get them clean, did the oven cleaner carb cleaner and still had to scrape them. He just used some carb cleaner and scotch brite. He swiched to redline this year and his valves were even cleaner one he just used a rag on the other had a small amount of build up that came off easily. So ill be switching as soon as I run out of Gold. Some of the difference may be the finish on the rev valves is smother than on the polaris.
also he bought the redline for $39 per gallon from the polaris dealer which is the same as the gold.
