Seafoam fuel treatment ?? in my Boxster
 

I have used this product in my other vechicles with no problems but have concerns with useing it in my Boxster because of the design off the engine and a certain amount will
seep past the rings into the case and mix with the oil.I usually just add 1 bottle at storage time to a full tank and burn it off after about 1 week off driving in the spring.
Doo u think it will be ok or will it dilute the oil.I think it says some were that u can add to oil but don,t have the empty cannister to reread.I change my oil in the fall before storage as i dont want the acids causing problems especially with the IMS seals.Anyone advise.thx

Use fuel treatments (like Seafoam and Cheveron's) prior to your oil changes, not after.
