How much seafoam per gallon of gas

If one quart of Mobil 1 synthetic oil costs less than half a quart of SeaFoam , why would we consider one the best engine oil in the business, and the other a scam? The truth is, most of the negative opinions come from people who have never even tried SeaFoam.

The weight of those unsupported claims cannot compete in the slightest with thousands of positive reviews from people that actually used the product.

Companies typically gain more trust the longer they are in business, but for SeaFoam, it seems to be working in the opposite direction. The chemical composition of SeaFoam is a well-guarded trade secret, but by looking at the safety sheet I found the two primary ingredients:.

SeaFoam mixes with fuel and cleans the entire system up to fuel injectors. Depending on the size of the engine, one to three full fuel tanks mixed with SeaFoam should be enough to clean the engine.

You can even compare the results yourself by using a boroscope inspection camera. Using SeaFoam as a fuel additive is straightforward. For regular use, add one ounce per gallon of fuel. A standard can of SeaFoam contains 16 ounces of cleaning solution, so plan your refuels to make the most out of it. For farming equipment and outboard motors, you can add 1 ounce per gallon of fuel every three months.

Any price and availability information displayed on [relevant Amazon Site s , as applicable] at the time of purchase will apply to the purchase of this product. You can repeat the process for all cylinders, but one should be enough.

Fully refuel, then mix in at least 2 ounces of SeaFoam per gallon of fuel. Once you start running out of fuel, repeat the process but use ounces of SeaFoam. On the third refill, do the standard 1 ounce to the gallon. Install the app. For a better experience, please enable JavaScript in your browser before proceeding.

I have a 40 HP 2 Stroke Merc. I only fill 6 Gallons a time on my bass boat. The rest goes into my jeep I do this so at most times there is sea-foam in the gasoline to stabilize, and every other tank it is stronger to keep the engine clean. So far no problems. Thats a good idea. Joined Apr 28, Messages 1, Just seems a little like snake-oil esque claims to me. Silvertip Supreme Mariner.

Too expensive to use it as a stabilizer in the boat. Click to expand Joined Nov 11, Messages 51,
