You can use SeaFoam in the gas tank, oil, or direct vacumm feed through the brake booster line.

There are some caveats and issues with too much into the motor via vacumm lines and I suggest you do a search for SeaFoam.

Other than that, it's a good product and I have used routinely to clean sludge from engines just before an oil change.

Also consider doing a web search on Seafoam and visit their site as they tell you how to use the product.

I used it and didn't like it seeing it fouled my plugs.

I did a water cylinder decarbonization treatment and it work GREAT!

Do a search for Water Cylinder in this section.
