Hi, I really wanted to buy Byron fuels to try them out so I bought some 30% fuel with 11% oil. I was wonxpdering if I could mix some kind of oil in the fuel to make it heli compatible.

Thanks

So you want to add some mystery oil to Byron airplane fuel to see if you like Byron heli fuel?

11% oil. Let me guess, it was for RC cars.

Bad plan. Hope you didn't buy a whole bunch.

Just asking. I do have cars too, not like I can't run them with this fuel. It was just that I couldn't find any Byron fuel dealers near I-5.

Sure you can add the proper oil to turn your RC car/truck fuel into heli fuel. Most car/truck fuel contains about 2% castor oil. This is not a bad thing as it can provide added protection during a lean run not otherwise provided by the synthetic lubricants. My advice is to add enough oil to bring the total oil content up to about 18%. IMO, there is too much oil in heli fuel already. 22-23% is not needed for lubrication. Most of it just gets spit out the exhaust and robs power as it displaces fuel. It also contibutes to a hotter (yes hotter) running engine because it displaces fuel which has a high latent heat of vaporization with oil which has none. However, if you want to keep within most engine manufacturer's guidelines, go to 22% oil content. One last thing, make sure you properly tune the needles. Any lower oil content will increase the fuel content (methanol is fuel) above standard 30% heli fuel.

This project is a recipe for disaster. I hope this isn't some $500 90 size engine you're going to do this with. Of course you can add oil to an existing fuel to provide enough lube to get away with what you are wanting to do. There is more to this than just % of oil content. There are different oil types and viscosities to take into consideration. Then there is the question of compatibility between the oils in the fuel and the stuff you want to add to it.

If you can keep the engine temperature under control, you don't need that much oil. The extra oil is there only to keep the engine lubed if the temperature gets too high. Castor oil is still a bit better at that than synthetics but leaves those ugly brown spots on hot surfaces (mufflers).

It will work just fine. I have added Klotz and castor to fuel for years and never had a problem. I have even mixed different brands without issue. If you add 11oz of oil, you will be at 18% oil, and 27.6% nitro. If you want, you can even test after you are done by taking a test tube and filling it with the fuel you have just added oil to. Measure the level and then put it in the sun for a day or two. All the acohol/nitro will evaporate, and you will be left with just oil. Measure the oil that is left and calculate the percentage. Just take the smaller measurement, multiply by 100, and then divide by the bigger. So if you had 5 inches to begin with, and ended up with 1 inch of oil after it evaporated, you would have 20 percent oil.
