Is there a way to tell what kind of oil I have in my tank? I bought the sled used any don't know if the guy was using regular oil of synthetic. I just dont want to have any problems mixing oil. Any help would be appreciated.
The easiest thing for you to do would be just drain out the existing oil in your oil tank and refill it with the oil that you want to use, be
it synthectic or reguler 50:1 two stroke oil. The small amount of oil that might mix in your injector pump if they are different, won't have any effect the on motor.
