Answers:    If your running a stock engine you should be capable of.

Try some regular unleaded, and get yourself a bottle of octane booster. Do not put the octane booster within your tank at first. Fill your reservoir (or what ever you can afford to do) with regular. If you start to hear a rap or knocking when to get moving, then put contained by the octane booster and try to go up to Mid-grade.
This may appropriate a few fillings contained by order to run out the elevated grade you hold in within. After about 3 or 4 cistern fulls, if your not knocking, travel ahead and drop in the octane booster. It will facilitate keep you fuel system verbs.
