Fuel

• Mix a ratio of gasoline to oil of 20:1 for break-in and

continuous operation on all engines.

• A mixture of high-quality 91 octane unleaded

gasoline and a reliable, high-quality 100% synthetic

oil for 2-cycle engines must be used. We recommend

Evolution Oil (EVOX1001Q).

With the use of an oil mixture of 20:1, it is normal to

see a slight amount of carbon buildup on the exhaust

valve itself. This is why it is important that you use a

high-quality synthetic oil instead of standard 2-stroke

oil you may be using in your 2-stroke gas engine.

Although these 2-stroke oils work well in their intended

applications, they can cause a build up of a gummy

residue on the exhaust valve in a 4-stroke gas engine.

This may require service for your engine if the exhaust

valve begins to stick and not seal properly.
The high-quality Evolution oil we recommend will still

build up a slight amount of carbon, but we have found

that this build up is easily flaked off during normal

operation of the engine. It will not create the typical

gummy build up.

• Remember to use caution in the storage, use and

transport of gasoline.

• Since commercial gasoline has many impurities,

please be sure to use a reliable fuel filter (SAI50109

or HAN143) in your fuel system.

• The recommended fuel tubing is Evolution

Gasoline

Fuel Tubing (EVOA102). DO NOT use a silicone

rubber fuel line for the engine, the fuel tank, or your

fueling system.

• The use of fuel with up to 10% ethanol has been

tested and found to work fine.

• The use of a filtered clunk or sintered clunk on the

fuel pick up line is required. The Evolution In-tank

Felt Filter/Clunk (EVOA106) is designed specifically

for gas engine operation.

Be sure to include a reliable fuel filter in

your fuel system. The drawing to the left

suggests the use of a fuel feed line and

an air intake line. Also, be sure to use a

fuel line that is compatible with gasoline.
