Yes and no, it depends. Most say gastrol GTX. The reason to use regular v synthetic is because regular burns cleaner. Synthetic tends to have more ash content. The oil is injected into the combustions chamber, thus needs to burn off. Regular oil will do this, synthetic does not as thoroughly (usually). Unless you are running premix without an oil injections system (AKA no you aren't), stick with regular oil. You'll save a few bucks and you'll be 100% safe anyway.

Cliffnotes for ^

Use regular oil, or use high quality synthetic.
