Or 2% of oil

I always think of mix being 1:50 - rather than 50:1 - ie oil to fuel, rather than fuel to oil - after all, I add oil to fuel generally, not the other way around !

ie - 1:50 = 2 :100 hence 20 to the 1000 ( ltr ) ( just seems easier that way )

It gets confusing when keeping mix at 1:50 which I generally use in my Suzuki tender - but then altering it to 1:20 for the seagull if I need to run it. 1:20 mix is 5:100 - 50 to the ltr. So if I need to run the seagull I know I add 30 to each ltr suzuki mix :ambivalence:

Our garden centre machinery dept has really handy mixing bottles, with which one can fill up to a level with petrol, then add amounts of 2-stroke oil to get mixture ratios marked on the side.

Although only a litre or so at a time these things are a godsend, before that I'd used small medicinal bottles I'd stumbled across which give the right mixture for 1 bottle to 5 litres of petrol = 100:1, 2 bottles = 50:1.

I still use those bottles, but at home for the garden machinery or anyone else who hasn't got those old bottles - sorry, labels rubbed off years ago - the mixture measuring things are great; obviously one wants to mix and prepare any fuel fuel before setting off or it might be a right pain.

I have a rule that any cans of raw petrol get the 2-stroke mixture instantly added, and must not be stowed in the fuel locker unless.

Hopefully this might save much anguish later.

That's not going to help much if your have a 30l tank and you need to refill it and there's some in it. You need to work out how the sums work.
100ml-to every 5 litres (5000ml) is a good start.

I use a "miniture" gordons gin bottle as the measure. It holds exactly 50 ml. so one shot of this does 100 : 1 mix in 5 litres of petrol.
simple arithmetic for different mixes or volumes.
Really handy on long trips / holidays as you can carry a shot rather than the big bottle / measure, and buy replacement petrol for the dinghy trips if you run out.
* Other spirit bottles are available as they say.

I do very similar, except I bought ten 100ml plastic bottles (50:1 in a 5l can) for a couple of quid from eBay. Decanted a litre bottle of oil into them and I'm set for the next few years at current consumption rate

All the 2 stroke oiI I've used in recent years has a clear strip down the side of the bottle marked off at 100ml stages.

...although that doesn't help if you still need to ask the Internet to do the arithmetic for you

the 2 stroke i brought is 5 lt and does not have a clear strip marked off in 100 ml stages..

But it does save having to buy lots of little bottles and decanting the oil into them...

In that case you will need to use 6 x 100ml bottles - or a 1l jug marked off at 100ml stages might be easier...

This 100 cm³ conical measure is what I use for oil measuring at home.

There is a larger one ( 200cm³ ) on the boat

I use an old spice jar with a bit of tape at the 50cc point. Because it has a wide neck, it's easy to fill without dribbling oil. Before that, I had a 100cc bottle from Morris Oils marked at the half full point but that had a narrow neck and I was forever spilling oil as I filled it. Then again, even spending most of the summer on the hook, we've still only used about 25 litres of fuel so it's not like it a major problem.....

My engine manual says to use 100:1 for emissions reasons, but from previous discussions the engine will probably last longer if I use 50:1.
I usually split the difference, sometimes more green, sometimes more engine friendly, so using a measuring cylinder is a bit OTT when aiming for somewhere between 50 and 100ml for a 5L petrol can, but I use one anyway.

The ancient Sachs Dolmar chainsaw I have just refurbished (it has a cam, points and a condenser!) has 25:1 stamped on the fuel tank cap. It should last forever although it kills the trees before I have a chance to cut them down.

You need one of these...

its marked with ratios and litres on the side, no maths required

You dont say what engine

some were said to run on 100:1 but later changed to 50:1 ( Johnsons and evinrudes)

50:1 is usually specified for commercial or heavy use even when 100:1 for leisure use.


If it runs happily on 50:1 use it!
