The Test Kit

A kit designed to test for the presence of oil in the fuel of 2 stroke engines.

The 2 stroke oil testing kit

What does the kit do?

The kit tests for the presence of oil in the fuel of a 2 stroke engine. All 2 stroke engines need lubricating with oil. Often the user thinks that a few seconds of extra use with neat fuel will not cause a problem, but it invariably does! If you forget, or your customers forgets, to mix in the oil, the engine will seize!

If you are hiring a product to a customer it is especially useful in demonstrating to a customer that their repair is not under warranty or that they have to pay for repairs under a rental agreement.

How does it work?

When fuel from your engine is added to the reactant, the mixture will remain clear if no oil is present. The mixture will turn opaque if oil is present in sufficient quantity. Familiarity with results will enable the user to determine the ratio of oil/petrol. It is recommended that new users test a known sample to use as a reference. This only need be done once for although the sample will gradually clear, all that is needed is to agitate the vial to restore the effect.

The Kit includes: Instructions, five disposable vials containing a precise quantity of reactant and five disposable pipettes.

Why the oil/petrol mixture?

In a four-stroke engine, the crankcase is completely separate from the combustion chamber, so you can fill the crankcase with oil to lubricate the crankshaft bearings, piston and cylinder wall.

But in a 2-stroke engine the crankcase serves as a pressurization chamber to force air/fuel into the cylinder. The piston acts as a slide valve. This ingenious configuration means that the 2-stroke engine has a much better power-to-weight ratio than a four-stroke. However it becomes imperative that oil is mixed with the fuel to lubricate the crankshaft, connecting rod and cylinder walls.

Vials used in the 2-stroke engine oil test kit


Each test is disposable. Each vial & pipette should only be used once because of possible contamination.
Dispose of liquid with your waste oil. Recycle glass & plastic.
