Fuel Additives

The avid motorcycle enthusiast knows that when used consistently, fuel additives are some of the easiest and least expensive ways to protect the engine of your motorcycle. Rust, grime, debris and water caused by increased ethanol in fuel can cause your engine to bog, stall and even seize in serious cases. A fuel additive will help keep your engine clean and running smoothly all year long.

We carry additives from top brands in the industry such as Yamalube, Klotz, Gold Eagle, Maxima, and PJ1 to boost and stabilize your fuel. Cleaning those important components of engine such as your carburetor, valves, piston/rings, and combustion chamber can be done preventatively every time you run these chemicals through your tank.

You can even turn some heads (and some noses) while riding your motorcycle around. Grab a scented gas additive from Manhattan Oil and leave a savory scent everywhere you go! With flavors like cherry, apple, cinnamon, and cotton candy, you will leave a memorable wake wherever you ride. Check out our selection of fuel additives today!

    Good booster

    Used this for the last few races. I've noticed a crisper throttle response but not really any gain in power. Just a clean crisp running engine. It will turn light colored plastic brown like others have said.

  • Klotz Nitro Power Additive

    Klotz Nitro Power Additive

    Andrew in TN

    Nitro additive

    Ran at 2 oz per gallon and 4 oz per gallon on a Raptor 700. 2 oz did nothing mayb smelled different not much. Tried 4 oz with a one step colder plug and noticed better throttle response and the smell was more noticeable. Now this bike had pretty much all the bolt ons that could be done with a stock engine. I also ran Klotz octane booster/fuel stabilizer along with it. The fuel I used was good ol pump gas 87 octane ethanol free. Things to note about this Nitro additive are it isn't recommended to leave in your tank so use it that day/night or drain.

    Was quickly impressed in how fast a change was experienced in trottle response and in improved idle for my KLR as well. I have already orders in more for my other bikes. Give your bike, and yourself, a opportunity to feel the improvement this little bottle can make. Well done RM and Red Line.
