Hi Wetlegs, for every gallon of petrol you need to put 1/6th of a pint of oil this is because a 2 stroke engine does not have an oil sump like a 4 stroke engine (the one you have in your car) and therefore without you adding oil to the petrol the engine would have no lubrication and very soon grind to a halt. Ordinary engine oil will do fine. You need to find a container that holds 1/6th of a pint something that you can mark of down the side in 1/6, 1/12, 1/18 and so on. 1/6th of a pint is about 3 fl oz. if you put to much oil apart from getting a very smokey engine you will not burn all the oil of and the plug will soot up and even worse oil up and stop working.
I hope this will be of some help.

On the side of the 2 stroke oil bottle there should be marks which is the guide as to how much you put in  Cool 
In my experience its better to have to much oil than not enough although you may smoke your self out if not careful  Laughing

Start with a known quantity of fuel from the forecourt pump, choose an amount that is going to make the maths easy!

Before you mix anything buy the best quality fuel you can. The cheap supermarket grades have a lot of Bio Ethanol in them and they can degrade quite quickly. Stick with one of the top brands, I recommend Shell V Power; it cost a bit more but will last much longer and also burns cleaner.
Buy a good quality semi syn or fully syn two stroke with a NMMA TCWIII spec (marine)
Your 2 stroke mix at 50: 1 is 100ml 2t, to 5 litres petrol.
If go to any supermarket you can get a measuring jug for less than a quid, just make sure it has millilitres on the side. Some get a small container (Poundland and Home bargains do sets in the Ladies Cosmetics Section), and pre fill a couple with the correct amount of two stroke for 5 litre of fuel.
Also if you are not going to use the engine for a long period of time, empty the tank and run the carb dry, as even with good quality fuel it can still degrade and cause problems next time you use the engine (this applies to all 2 and 4 stroke petrol engines in outboards chainsaws, strimmers, mowers etc..)

NB I don’t make a habit of looking in “Ladies Cosmetics Section”
