Seafoam safe on a high mileage vic?

Just wondering if it's alright to put it in a 97' vic with about 530,000 km on the original engine? Thanks for any sugestions...

What are you trying to do? Am I correct on over 300K miles? Whats the reason you want to run SF?

Yes, it is over 300k miles. I'm trying to clean out some of the carbon build it's accumulated over its lifetime and possibly get it to run better.

I would use it then, just being careful not to hydrolock the engine. You'd also benefit from using some auto-rx. I have seen great results from using it in 3 of my high mileage vehicles.

SeaFoam does wonders. Dont over do it though. :)
