To anyone who can help: I would like to know if I could use Itasca synthetic mix oil in my gas? I have used it in my boat although it does not turn as many rpm's as a Banshee. I am currrently using Maxima Pure Castor. It is good but expensive. Also, how much would putting 22' tires on hinder the performance? I need a little more ground clearance. Thank you in advance for your input. All replies appreiciated.
