Byron Originals markets a tested and proven fuel for nearly every possible model engine application. The complete fuel line now includes over 50 different products.
These are our most popular blends. Each is comprised of a specific ratio of Byron Degummed Castor Oil and Byron Fortified Synthetics. The Synthetic/Castor Blends give modelers the best of both worlds; the clean, corrosion resistant protection of a proprietary synthetic lubricant, plus insurance against lean runs that castor provides. We will confidently place the lubricating qualities of our synthetic up against our competitions’ castor oils any day of the week. The addition of a small percentage of castor compliments the quality of this superior blend.
Synthetic/Castor Ratio: The ratio of synthetic to castor is engineered specifically for the application. Performance Blended Premium Sport Fuels are blended with an 80:20 ratio of synthetic to castor. RACE Gen2 fuels (Except RTR20 Gen2, RTR33 Gen2 and Worlds Blend) are blended with a 50:50 ratio of synthetic to castor.
The clean burning qualities of Synthetic Lubrication have always been desirable, but until Byron Fortified Synthetics were introduced, additional precautionary measures taken by the modeler outweighed any clean running benefits of synthetic lubricants. Modelers needed to pay special attention to attaining near perfect needle valve adjustments to protect against lean runs, and special care had to be taken to treat the engine to an after-run oil or bearing corrosion was a very strong possibility. Byron Synthetics eliminate both fears. Not only have Byron Synthetics been fortified with additional corrosion protection, but load carrying capacities have also been increased with special high-pressure additives. Straight Synthetic Fuels are available in both our Premium Sport Blends and our Helicopter Blends which use a proprietary low-viscosity synthetic oil package formulated specifically for helicopter applications.
The high rpms of 1/2A engines are protected with a 1/2A Fuel that features 100% Byron Degummed Castor.
We do not claim oil percentages to be a proprietary secret. Oil content is so easily checked through evaporation that to claim it a secret should be embarrassing for any manufacturer who makes such a claim. Oil content percentages are stated right on the bottle of Byron Fuel. These percentages range between what is specifically needed for a certain application and what modelers want as a form of personal insurance and comfort.
Our most popular blends: Race Gen2 ranges from 6% to 16% total oil content depending upon the application and the recommendation of the engine manufacturer. Premium Sport airplane blends contain 16% total oil content. The three most popular Premium Sport blends of 5%, 10% and 15% Nitro are also available in what we call Traditional blends. (20% overall oil content) and our Premium 18 blends (18% total oil content). Helicopter and Race Gen2 Drag blends utilize different oil contents. 1/2A fuel is available in 16% total degummed castor.
For years, we were asked our theory on higher oil contents for breaking in an engine. Ever since we have been blending Byron Fuel, we have used nothing other than 16% oil content (80:20 synthetic to castor ratio) for break-in and we have always had successful break-in periods and longer than average engine life. However, we recognize that some wanted to use a higher oil content during break-in thus, Byron Originals introduced Lube Booster to meet the requests of our customers.
Lube Booster is sold in 12 ounce bottles and has become popular with modelers, not only for formulating their own custom break-in blends, but for adding to our competitors fuels to bring their lubricating qualities up a little closer to those of Byron Fuels. (Of course it is our hopes that these modelers just treat the competitors’ fuel until their present supply is gone and then buy Byron Fuel with not only the superior lubricants, but the proper ratios of each along with the finest methanol and nitromethane.) If you know the percentage of oil in the fuel you are treating, you can simply follow the bottle instructions for the number of ounces of Byron Lube Booster to add to bring your fuel up to a certain total oil percentage content.
Nitromethane represents a nearly perfect fuel that brings its own oxygen into the combustion process. While there are many theories on some of the effects nitromethane has on temperature and performance, none applies across the board in all applications and with all types and sizes of engines. The nitromethane percentage you need depends a lot on how your engine was designed and the engine manufacturers’ recommendations should always be considered one of your top recommendations.
Some modelers are under the impression that nitromethane contributes to a higher combustion temperature which is not always true. Depending upon how your engine is set up, higher nitro can actually turn down the heat in certain situations. If you experience predetonation, then it is recommended you go to a lower nitromethane level. Too high a nitro content can cause pitting of the top of the piston and the inside of the glow plug dome. If you run high nitro, you should disassemble your engine occasionally and check it for pitting. If you choose to run a higher nitro than normal, you may need to shim the glow plug head to compensate.
Increasing nitromethane does not always assure higher performance. Due to the cost factor, if you are a sport modeler, run the lowest nitromethane you can as long as your engine is starting well in cold weather and performance is smooth and responsive.
Even though you may select a higher oil content for engine break-in, you should always break your engine in on the same nitromethane percentage that you plan to run after break-in.
