Default Mixing Your Own Fuel

Does anyone have experience mixing their own fuel especially what oils to use. I hear Benol Caster is good stuff, but what is a good synthetic oil.. are any of the Klots 100 ~ 200 oils any good. I have been using AT Racing Fuel (16% nitro / 5% Syn / 5% Castor) but I not happy with the consistency this fuel provides.

try pure nitro klotz and just add benol (degummed pure castor oil) to 8-10%
and give it a try, works fine with itaLian mills

Any suggestions for good places to buy pure methanol and nitromethane?

At the LHS....

For the oil I use with great succes 3% Castrol Racing-M (formally known as M50) and 6% Castrol MSSR. Currently we are experimenting with Shell Racing-M which seems to work good as two 10th scale drivers were using it in the past season and one made it to national champion. The only problem with the Shell oil is that it has a very dirty combustion but with engines living up to 12 liter on maximum performance and still having a lot of pinch that is no problem.
The Shell oil is very thin (SAE30 specs) which must help reaching high revs.

I am not sure where to get the nitromethane but I do know you can get pure methanol at your local farmers CO-OP, they use methanol to fill tractor tires instead of water because methanol wont freeze

just wondering? is it cheaper to mix your own fuel, or does it just allow for more tuning options?

25% fuels in Holland:

5 liter Runnertime: 75 euro (15 euro/liter)
5 liter Tornado: 55 euro (11 euro/liter)
5 liter Merlin: 60 euro (12 euro/liter)
5 liter Model Technics Dynaglow: 40 euro (8 euro/liter)


Mixing my own: 4.50 to 6 euro/liter (depending the prices of the ingredients)

I was wondering if you guys are figuring your nitro % by weight or volume? Also how are the manufacturers doing it? I know nitro is heavy so I figured they did it by weight making it cheaper.

I mix benol and Klotz Techniplate, make sure you get high grade methonal 99.9 percent pure. The next grade down is 98.5 and apparently terrible for your motor. Also make sure you get good quaility nitro too, we have had issues with poor nitro turning the fuel black when mixing with Nova oils, not the oils it was the nitro.

I think the nitro comes from Grace Chemicals but will need to check on that.

Also Roelof I know you mentioned that you got your last batch of MSSR at a car workshop in the UK? If I can get my hands on Castrol oils I would be mixing with that, I hear its brilliant. Do you change head clearences with diff fuels? I am sticking with 0.7mm which seems to be safe.

I work by volume, makes sense to me. Cant imagine having to weigh fuel as apposed to measuring it. And if that how manufacturers do it then you pretty sure what you mix will perform better. Nitio is expensive so there will be people taking short cuts. Heard of a 16% nitro gauge not floating in 25% fuel

The older types of Castrol oils can still be obtained at a special department at Castrol called Castrol Classics:
