LEARN HOW TO GET THE MOST OUT OF EVERY MILE

Whether you’ve just bought a brand new car, drive a beater or maybe an old classic, you want that vehicle to run like it did when it rolled off the assembly line. The compromise is now over, with Gumout® Supreme Fuel Injector Cleaner + Octane booster you no longer have to choose between clean fuel injectors or octane boosting performance – you can have both!

IS YOUR VEHICLE PERFORMING AT ITS PEAK?

LEARN HOW TO PASS

Do you cringe when it’s time to take your vehicle in for an annual emissions test? Carbon deposits in your fuel system can cause poor combustion that results in excess exhaust emissions. Once they get to a certain level, your engine will fail the test. But you don’t have to stress out, Gumout has a line of products that clean up your fuel system and help improve combustion efficiency resulting in lower emissions.

LEARN HOW TO BOOST MPG

Did you know that with every fill up of your gas tank, carbon deposits start forming on key engine parts? As they grow, your fuel economy suffers because these gummy deposits cause your engine to work harder, reducing MPG. Gumout has a line of products that clean up your fuel system and help restore fuel economy, saving you money and extending the time between fill ups.

RESTORE GAS MILEAGE

Restore Gas Mileage

LEARN HOW TO RESTORE POWER

There’s nothing more frustrating than trying to merge onto the freeway and your engine doesn’t produce the power you expect and need to safely enter traffic. If you want to experience all of the horsepower and acceleration your vehicle was designed to give you, pour some Gumout in your tank. It will remove carbon deposits, reduce friction and help boost your engine’s performance.

FIX LOST ENGINE PERFORMANCE

LEARN WHEN TO USE GUMOUT

If you have never used a fuel additive before, it’s never too late to give Gumout a try. Our products are designed to fix engine problems like hesitation, rough idle, poor gas mileage and loss of power. Once you’ve fixed the problems, make Gumout part of a regular maintenance schedule so these issues don’t return. Or if you’ve got a brand new car or truck, use Gumout from day one and you won’t experience reduced engine performance.

FIX IT AND MAINTAIN IT

GET THE KNOWLEDGE

If you have a car, it can be tempting just to ignore any type of maintenance unless something goes wrong. We probably don’t have to tell you that this is a bad idea. However, not everyone agrees on what preventive maintenance is, what you should do and when you should do it. Let’s clear that up, and give you some tips that’ll apply to any vehicle.
