Just Engines Model Fuel Info

An Engine is only as good as the fuel you put in it and the easiest way to damage it is to use the wrong fuel. Here are a few pointers that will help you make the right choice.

Firstly and most importantly read the engine instructions and be aware of the best fuel mixes recommended.

Glow fuel: (Nitro, Methanol and Oil Mix)

Make sure you know the oil and nitro content in the fuel you are using (or are being sold by your supplier).

As not all fuel makers put the contents of the fuel on the outside of the container see the tables below (and manufacturer's web sites) for this information.

If you don't know the oil and nitro content of the fuel - my advice is; find out - or don't buy it!

In general most 2 strokes will be happy on 18-20% oil (preferably with at least 2% castor) and are timed for 5 - 10% nitro (eg O.S., Irvine, ASP etc..) - but always check the engine instructions.

In general most 4 strokes will be happy on 15-18% oil (preferably with at least 2% castor) and 5% nitro (eg O.S., ASP etc..) - but always check the engine instructions.

Yes - you may 'get away' with less oil than most manufacturers recommend - but if you have a couple of lean runs on a hot day - expect a repair bill. So always try to set engines 'a couple of clicks rich' on the ground.

It is cheaper to do a 'de-coke' than it is to do a repair!

Does Glow Fuel go bad? Generally no however methanol can mix with water and this will affect the performance. If in doubt try some new fuel.

The following tables (correct as far as we know) are from the 2 most popular UK fuel suppliers (in alphabetical order).

Name Nitro % Castor % Synthetic % Methanol Paul's Notes
Straight 20 80 FAI fuel and excellent for running in engines that need no nitro
GN or GX various 20  20% castor never hurt an engine - (particularly 2 strokes) re read note 5 above! (2 stroke mix)
Dynaglovarious28  
Duraglovarious 69 excellent 4 stroke mix - but not really suitable for modern 2 strokes*
Supaglo various416 nice modern clean running 2 stroke mix
Ripmax various 15   
Formula Irvinevarious 18  nice modern clean 2 stroke mix, or high oil FS mix (14% klotz, 4% castor)
Goglo  15   
Regular Four Stroke   10   
Special Four Stroke   9 9   good for modern FS engines - and (despite fuel name) for high oil 2 strokes eg Moki
Tigre Big Brute   4.5 6.5   for ST larger engines eg ST2000 and above
Laser Mix   2 15   also good for most FS and some 2 strokes
