Ariel initially recommended 25 to 1 but in later information recommended 32 to 1 of some oils. I've used 32 to 1 in my standard Leader of any of the major oil makes ie. Castrol, Putaline etc. I find semi synthetic gives less smoke and is not too expensive. .Brian H ps the engine has done 17,000 miles since last rebore and still has good compression.

I use a modern synthetic oil at a nominal 32:1 in my Arrow with no problems and without excessive smoke. I say nominal as I measure 300 ml and add 10 litres of fuel, but there is always some oil left in the measuring bottle.

hi richard ;
the tank cap is there to be used as an oil measure , 2 1/2 caps full to one gallon [ 1 cap per 2 litres ] .
i use comma 2t or ryobi 2 stroke oil but to be honest any 2 stroke oil is fine .

Modern oils for 2 strokes don't smoke or carbon up as much but some MUST be better than others. Mixants and formulations change and most ordinary engine oils lower the octane rating and some additives may short out Plugs when they get on jnsulators. Don't use TCW3 as it's only for Outboards. Nev

On this side of the Atlantic VR1 is a 4-stroke oil, you need a 2-stroke oil - one of the Valvoline 2T types?
You should easily be OK with 32:1 (or higher - I think some guys here are using 40:1) with modern oils but you'll have to decide on mineral, part synthetic or full synthetic! (There are strong opinions either way....)

hi Richard .
the fuel tank cap is an oil measure , you use 2 1/2 caps full of 2t oil per gallon/ 5 litres of petrol .
it also equates to 1 cap full per 2 litres of petrol .
i use comma 2T oil which is a mineral oil , or ryobi semi synthetic ,self mixing oil for 2 strokes but you can use any oil suitable for a 2 stroke fuel mix , oils for 2 stroke strimmers or concrete disc cutters etc are fine and easier to obtain in many areas from builders merchants or garden centres , or you can use oils for 2 stroke motocross bikes etc .
you can use 2 stroke outboard motor oil as well .

loads of companies make 2 stroke oil so you wont have to go far to find something .
