Status: offline 		I need some heelp to see if these numbers are correct. I'm wanting to increase the oil content of a fuel to 50%syn50%castor. The fuel I'm using is Cooper's 20% nitro 20% lube(16%syn.4% castor).

Here are my calculations.

128 .ozs to a gallon. I'm adding 15 .ozs of castor to the fuel.
New mix 143 .ozs Nitro 17.90%/25.60 .ozs
Meth 53.70%/76.80 .ozs
Lube 28.39%/40.60 .ozs (Syn.14.32%/20.48 .ozs-Castor 14.06%/20.12 .ozs)

I know that my oil mixture isn't exactly 50/50, but it's close enough for me. Would someone please take a look at these numbers to see if they are correct.? This is the first time I've ever attempted to add Castor, so, I'm not too sure if I'm figuring this correctly.

Any input would be greatly appreciated,

John

Status: offline 		Calculate your new percentages and add them if they equal 100% total. Then you did your math correctly. Add 15.36 fl.oz. to bring up to 50% castor in your oil mix. Your fuel will be 17.9 percent nitro and 28.4 percent oil.
