Hi , guys

Just wondering if anyone has switched from reg gas to hi test and if so what did you see and is there any ill effects to the sled 08 apex

thanks

Mine ran better with more RPMs and top end with reg. (07 attack)

On a stock sled? Just run regular save your money. Hi-test just has a higher resistance to ignition than 87.

Really did not notice a difference. Lake king either way!
