i dont know if thats good for your engine.

 

lucas is more of a light fuel conditioner and with some other lubercates. Seafoam i add to the tank every three months that's every 10,000 miles or so. "Im proactive" I have never had a problem till now.

guess i will wait for others to chime in. if i shouldnt use it let me know and i will quit. but iv'e owned many performance cars "Nitrous, Supercharged, Turbo, Turbo's" and have never hade issues.

I allways run ultra 94 gas from sunoco i never stray away

 

Ditch the seafoam, check your hoses on top of your valve cover for leaks. You might need some new plugs.
