if you ever need to change oil due to water or in your case,gas, you should be alright to just use regular 10w40 oil. I had drowned my bike before and it needed a total of 9 oil changes to get the water out. I didnt drive it,just let it run for about 5 min. each time then drained it. I just used regular 10w40 till it was gone and finished with arctic cat synthetic oil.

 

wow, thats alot of oil. Thx
