Default Nitro, oil content

Most of my engine manuals specify 5-30% nitro and 20% oil blended fuel. I have yet to find a nitro fuel that has 20% oil. Has anyone?

That doesn't sound right. Most Recommend 20% Nitro. Average oil I would say is around 11 or 12%. Race blends will run 8%. I know Byron's is 11 for the Gen 2. If you are new I would get 20%. It is a bit easier to tune than 30% but will have a bit less power. Most wouldn't even notice. I run 30% though.

I could be wrong but I don't think Heli blend of 30% nitro has a 20% oil content. I think it's around 16% to 18%, and if you've see us fly, we smoke like a "hippy compound".

It would be nice if everyone listed the oil content on the bottle or it was available somewhere.

Byron's has all that information for their products on the web site.

http://www.byronfuels.com/pages/products.html

They also put it right on the label, at least for the aircraft blends.

Morgan's also has the info on their site for Cool Power/Sidewinder/Omega.

Both have blends with 20% oil content, if that is what you want.

Most racing fuels for cars have 6% to 12% oil content, very hard to find a "race fuel" with 20% oil ...

Look into airplane fuel, specially YS 20/20 from wildcat fuels ... that have 20% oil ...

Some of the maunfacturers do list the oil content, but Werks, O'Donnells, and TQ don't. Maybe I should just stick with one that lists the oil content, but I got some good deals before the prices went way up.

All three of those fuels will run great and have oil content somewhere between 8 and 14%. You will never need more than that no matter what your manual says.

Higher the oil content hotter it will run. It's the fuel that cools the engine not oil.

We had abunch of racers that was adding oil to there fuel thinking it will cool the engine. Makes it harder to tune, lots of flame outs, eats glow plugs faster and besides the bigger mess it make on the side on the car
