DIY Top End Cleaner/Seafoam (cost under $3)

[SilverSoarer]

The best top end combustion cleaners are marketed and sold by dealers under names such as GM Top End, Toyota Combustion Cleaner, Mopar Combustion Chamber Cleaner, and Yamaha Combustion Chamber Cleaner - all of which retail around $10.

Seafoam is mostly naptha oil (a solvent) and rubbing alcohol.

The active ingredient in factory products is a 2-butoxy ethanol, the rest is VOCs/petroleum distillates and solvents.

For about $3 one can make your own.


1 part generic carburetor cleaner or throttle body cleaner
1 part simple green (contains 2-butoxy/butyl cellulose)
optional:1/2 part rubbing alcohol or methanol (can use windshield washer fluid, dye is inactive)

mix in metal container.

Disconnect intake hose and piping leading to throttle body (do not use brake booster) - this allows all cylinders to receive cleaner

re-connect intake hose losely with a small hose inserted to intake, dip end in container.

run engine and it will be sucked in by heat pump vacuum action of engine

So for about $3 you have a cleaner that is better than Seafoam, and does as good a job as expensive factory versions - and you are $7 ahead.

Great money saving tips, but $10.00 for some high quality cleaner really isnt that expensive. But every penny saved is always a good thing, especially here in Canada with our new tax, gas went up 8 cents a litre!

I don't think the idea of dumping Simple Green into my engine is something i'd really want to do...for parts yes, for the inside of a running engine: i'm inclined to say no to that.

uhm ... are you sure that is safe ? i wouldn't do that, that is an untested mixture ... who knows what it can do to your engine ...
