I heard that the xtreme engine flush from z1motorsports works really good with removing engine oil deposits and improve performance.
Im about due for an oil change and thinking about using this
is it any good? Is it worth the 30 bucks? Does it really improve engine performance?
thanks

 

Does your motor need it? (aka has built up gunk / sticking / ticking lifters)

 

A. Very minor lifter tick when parked still for a few days but when i drive it normally its barely noticable.
Will it help the car run smoother?
