Fuel System Using our after run oil will protect your fuel system and Engine.
The function of the fuel system is to store and supply fuel to the cylinder chamber where it can be mixed with air, vaporized, and burned to produce energy
Gasoline is a complex blend of carbon and hydrogen compounds.
NITRO FUEL
Model engine "glow" fuel is made up of three key elements: methanol, oil and nitro methane. Let's address the most common elements of the fuel and how you can care for your fuel to keep it fresh and stop it from going "bad." These steps will ultimately make your model engine operations easier.
The largest portion of the fuel is methanol (alcohol). Methanol is hygroscopic, it attracts moisture (Our after run oil will control this problem). This can cause your fuel to be contaminated with water, which will cause poor engine performance. The UV rays in sunlight will eventually break down the nitro methane if the fuel jug is stored in sunlight for long periods of time.
How can you tell when your fuel has gone "bad"? You can also combat the effects of the moisture in the air by squeezing all the extra air from your fuel container at the end of the day or transferring your fuel into smaller containers as the level of the fuel is reduced in your jug. Many individuals will invest in half-gallon or quart-size containers and only bring that amount of fuel to the field on any given day. This allows their main supply of fuel to stay at home in a controlled storage environment, virtually insuring problem-free fuel.

Fuel Information plane Vs car fuel
The main controversy seems to focus on how much and what type of oil is needed for a car fuel.
At klotz warehouse our products have years of research and experience and the results of testing Our oil's in many formulas in all types of engines and conditions. Using our after run oil will help your engine and fuel system operate at .
Why Not Airplane Fuel
Car engines operate in a totally different environment than do airplane engines. Airplane engines spend a great deal of their running life at full rpm, they have a constant airflow from the prop to aid in cooling and the instant throttle response and acceleration is not as critical as with a car engine.
Car engines spend most of their throttle accelerating from one corner to the next and are seldom at full RPM for more than a few seconds. They rely on an oversize heat sink head to dissipate combustion heat and racers actually tune car engines based on throttle response.
Fuel designed for airplanes typically have from 15 to 20% oil. While car engines typically put 8 to 12% oil in their car fuel.
Why 8% to 12% Oil
Using high oil content fuels (above 15%) in gas car engines might not provide improved engine life, as some would expect. There has been testing were for some fuels and oil mix the point of diminishing return as far as oil content to engine life is actually around 8% for most car engines. For this mix more oil than 8% in the fuel does noting to improve the life of a car engine. Some effects of high oil content fuels can actually cause engine damage by encouraging over lean runs.
Using high oil content fuel can cause a car engine to be unresponsive during acceleration acting as if the engine were running rich. When using high oil content fuel, in order to get crisp acceleration and response, an engine will need to be adjusted overly lean.
Helpful Rule #1- Always use a high quality fresh fuel designed specifically for gas car use that has between 8% and 12% (yes you can use more) oil preferably with at least some castor in it. (We recommend Klotz Benol at klotzwarehouse.com)
Helpful Rule #2 - Don't use airplane fuels or any other type of fuels that have over 15% oil in your gas car engine.

NITRO: The basic mixture for Glow Fuel is;
80% Methanol + 20% Oil by volume
This will run well in most Glow Engines, however you may want to add a few other compounds to pep it up a little bit.
Nitro-Methane can be added to improve power, a good sport type mix is;
5% Nitro, 75% Methanol and 20% Oil
You can continue to increase the Nitro content up to about 15% by reducing the amount of Methanol you use. DO NOT reduce the oil content, the old saying is if in doubt add oil.
There are several types of Oil you can use, Castor Based (Our Benol) or Synthetic (supertech with Synthetic and 20% benol-castor). There is much conjecture about which is better, however it is your decision to define which side of the line you are going to stand on. Personally I use Castor for only one reason, if you do accidentally lean your engine out to far, castor usually will protect it better than synthetic oils.
A lot has been written about this Topic, but in the end it is your decision.
Here is a simple spreadsheet to allow you to work out the amounts you need. The instructions are inside and it is a free download, I hope it is of some help....Here is link Fuel_ Mixing_Sheet
Gas:oil fuel mix ratio charts are a handy reference for those using any type of engine that requires mixed fuel. Use the print button on your browser to print out a copy to keep in your garage, your boat, or anyplace where you might end up making up an gas/oil fuel mix.

Note better to KEEP IT RICH
Once again we stress as you increase the use of Nitromethane you must run well on the rich side, even up to the point of the engine starting to misfire on the run, regarding the cost of the fuel as an insurance against engine failure caused by the increased power developed as the percentage is increased.
