says it on the can..1/3 in oil..1/3 in the vacuum 1/3 in gas tank

 

Well i have used sea foam a few times and not noticed any improvement and i have done exactly as the bottle said, Now im not saying it didnt improve something in my motor, Im just saying i didnt notice an improvement

 

well thanks for clarifying. i normally just run in through the vacuum through the intake and in my gas tank.

 

I have used Sea Foam for years and love the product. Curious, i just cleaned out my throttle body and was wondering about the best place to inject the sea foam for the upper end cleaner. I have an 08 silverado with the 4.8L (25K miles) is there a better vacuum hose or is the brake booster still it?

Thanks

eric

 

I find it hard to believe one product can work all of this magic? Can somebody explain to me how it works exactly?
