Seafoam

[Denali0229]

My truck just went over 60k miles. Will it be worth doing a Seafoam application on my truck? I'm hoping it might help my gas mileage some b/c right now its horrible. Also, which valve hose do I put the Seafoam in? I'm a total newb on engines. I watched a few videos but I'm not 100% positive. Supposedly I take 1/3 and pour it into the valve hose, 1/3 in the oil compartment and the last 1/3 in the fuel tank then wait about 10 minutes. Then I drive it around 10-20 miles. Sound right?

you can pour a little at a time through the brake booster hose. I just use it in the gas tank and the rest through the brake booster hose. You can rev it on the spot and sometimes make a smoke show and sometimes nothing at all.

Like Sumo said, do it through the hose that comes off the brake booster. Make sure the engine is running when your do this and don't pour too fast or you'll stall your motor. I also put 1/3 into the gas tank and use the other 1/3 on the oil right before I do an oil change.
