Yes, carburetor deposits are typically easier to clean than those found in fuel injectors and the chemistry used in the Injector Cleaner products will also effectively clean carburetors.

While all Gumout? Fuel Additive products include directions for use and a recommended usage interval, each product has also been through rigorous "no harm" testing and can be used as often as every tankful of fuel. Products recommended for use in every tank should be used every tank as indicated on the label.

Fuel Injector Cleaners are designed to clean through the fuel injector system and Fuel System Cleaners not only clean the fuel injector system, but go beyond, to help remove deposits from pistons, intake valves, and combustion chambers.

Typically, injection pressure is over 20,000 lbs. per square inch in engines that meet EPA on-highway emissions requirements.

These fuel additives are referred to as "Keep Clean" products. Just as brushing your teeth keeps harmful bacteria from building up on your teeth, STP® Gas Treatment and Fuel Injector & Carburetor Treatment help keep harmful deposits from building up in your engine's fuel intake system, including fuel injectors and carburetors. It is important to keep your fuel system free of deposits in order to maintain maximum performance. These STP® products do not remove existing deposits.

Injector cleaners clean injectors with a solvent or detergent that washes the deposits out the exhaust. Dipetane converts unburned fuel to energy instead of washing it out. In addition, injector cleaners do not clean carbon deposits out of the combustion chamber. Dipetane does.

These vehicles are designed to run on multiple fuel types, including E-85. Gumout? Fuel Additives will only address fuel deposits resulting form gasoline, and not any issues related to E85. We do however recommend strict adherence to the oil change interval specified by the manufacturer when using E-85 fuel.

Fuel injection requires a pressurized fuel system that the carburetored cars do not have. You will need to change the fuel system and a large portion of the wiring harness to put a fuel injected engine in your car.

While most Gumout? Fuel Additives are not recommended for use in 2-stroke engines, we do offer a couple of 2-stroke specific products. Gumout? Small Engine Gas Treatment is recommended for use in all 2-stroke engines, while Pennzoil? Marine Fuel System Cleaner is specifically formulated for use in 2-stroke marine engines. Yes, you may use any of the Gumout? Fuel Additives in these engines. The treat rate should be 1 ounce of Gumout? product per gallon of fuel.

Gumout? Fuel Additives are not recommended for use as parts cleaning solution. However, Gumout® offers a line of maintenance aerosol products for cleaning specific parts of an engine or car (Brake Parts Cleaner, Air Intake and Throttle Body, Carb and Choke, and Engine Degreaser/Cleaners). See specific use instructions on each product.

The size of the fuel injector you choose to run depends on the amount of power you desire to produce. In simple terms, it takes fuel to make horsepower. Vortech supercharger systems are designed to use stock fuel injectors in most cases or have additional fuel system provisions in the supercharger system.

Many things affect fuel consumption. You would assume that a modified (faster) engine would use more fuel, but they can in fact be more economical .The reason for this is because with more power you will not have the throttle open as long between corners (you should get there faster). If an engine has been modified and is significantly worse on fuel consumption than it was before, the alterations that have been made are not working efficiently and are wasting fuel.

Fuel injectors can cost a hundred dollars or more a piece, and you may have one for each cylinder. Cleaning them before they are plugged can remove harmful deposits and keep them spraying in top form. After they plug, replacement is sometimes the only option. It is very important to keep the fuel injector clean, The most common form of injector fouling comes from unused gasoline evaporating inside the injector after you turn the car off.

You don't, but for best results and to facilitate better mixing with your fuel, we recommend you add to a nearly empty tank, fill the tank, and then do not fill again until nearly empty. This will allow you to get the most benefit from the product chemistry due to longer use at the recommended effective concentration.

In general, modern engine management systems will compensate for fuel octane, and once you have satisfied the optimum octane requirement, you are at the optimum overall performance area of the engine map. Tuning changes to obtain more power will probably adversely affect both fuel economy and emissions. Unless you have access to good diagnostic equipment that can ensure regulatory limits are complied with, it is likely that adjustments may be regarded as illegal tampering by local authorities.

Ahh, an easy question. I'll give you all a break on this one and try to make it a short explanation. The engine will run on any fuel that is combustible. Testing is being done on propane, as it is much easier to use since it does not require pumps and other associated gear during the tests. I will be running the engine on diesel fuel during actual runs though. For those interested in a few more facts about the fuel, read on.

Contact lenses are exposed to a complex environment whilst on the eye. The tearfilm contains a number of different proteins which potentially adhere to the surface of the contact lens. The buildup of protein reduces the wettability of the surface of the contact lens which causes a "smeary" or "fogginess" to vision. A protein cleaner, often an enzymatic agent, will help in reducing the potential for protein to adhere to the contact lens surface.

Absolutely! We use very high quality (high cost) slide pots and like a fine race car, maintenance is critical. If you keep the pot clean and lubricated it will last many years. If you neglect them then try to restore them with a generic cleaner you will just have to replace them. Don't just use any "contact cleaner", see our Detailed Slide Pot Care Procedure.

Answer: The SMT6 can retard and advance ignition signals going to the distributor, but will not be able to do anything for the fuel with these types of cars. Answer: No, this information belongs to our dealers. We do not have any maps of our own. Please ask your dealer or contact us!
