Fuel Oil mixing

[gshaw]

Folks I am getting tired of mixing small amounts of fuel and oil and adding it to the big fuel can and have tried the measure the amount of fuel and add the correct amount of oil worked out by calculator. So was wondering what does you folks do/use to mix fuel/oil 50:1 100:1for the outboard (yep some of have outboards THAT old)

I have seen neat oil fuel mixing containers but they only handle 1lt at a time it would need to be 45lt or am I stuck to measuring oil and adding to the main tank?

Just measure the amount of oil needed for the amount of neat petrol according to ratio and add it straight to the main tank, and shake!

It is not clear from your post how much fuel you want to mix at one time. A few litres or several tens of litres.

This is what I use for measuring oil for small amounts of fuel.

( I also have plastic measuring jug for small quatities of petrol)

I have a larger conical measure for larger volumes of oil when mixing 5 or 10 litres of fuel ( or more ).

Cheers yes I have a small mixing bottle that will do 1lt @ 50:1 no problem, I am thinking more of 40lt at a time.

Guess that I just measure the oil in a separate container and dump into the tank?

My concern with direct to tank mixing is that the exact amount of already mixed fuel left in the tank will then be mixed with the unmixed until I then add to much assuming I add worked out on the tank capacity, where I should be adding only the amount required for the new fuel which means I need to know how many liters I have added Yes probally not that critical but I would still like to pre mix.

Looked today at a thing called a FlowNGo 45lt on wheels with its own hose, anyone here use one?

When i use the chainsaws i fill a 25L jerrycan with exactly 25L of petrol and just dump in 500ml of oil, i have an old graduated 500ml two stroke oil bottle with the clear side strip and its marked in 100ml increments.

Alternatively you can tip the oil in first, then add the petrol, this will virtually mix on its own. I prefer the 25 litre jerrycans as they mix in bulk, but are not too heavy to shake to mix the oil and petrol before use. They are also easily handled when transfering the fuel to a tank or smaller container.

But how do you measure exactly 25 l into the Jerry can . Do you have some form of approved and authorised storage facilty with an accurate metering system?

I think you will find that in the UK 10 litres is the largest size of can you can legally use for the purchase, supply or storage of petrol.

I think also that 20 litres is the maximum amount you can store without without authorised and approved storage facilities.

I fear therefore you may be suggesting illegal practices.

Vic:

You are both right and wrong due to local legislation.

Transporting of petrol by vehicle is limited to 10 litres in a plastic container, but with an approved metal container it is 25 litres, but the metal container must be approved.

Local storage of petrol varies from region to region, again in a plastic container this is strictly limited to 10 litres, but varies from 10 litres to 40 litres depending on local legislation, if stored in an approved metal container. I live near the border of three counties, in ours it is 30 litres, one is only 10 litres, and the other is 25 litres. Many very rural or remote areas such as the Highlands of Scotland allow the maximum 40 litres due to their remote location.

This changes if it is not plain petrol, if it is a two stroke mix for non vehicular use such as chainsaws or other such uses it is raised to 25 litres, but it has to be mixed prior to transportation, and again must only be in an approved metal container. This is the reason there is a stain in the two stroke oil, i use Castrol and it turns the petrol green, this is proof of it being mixed two stroke and not plain petrol, i used to use Silkolene and this turned it red. If you are stopped by the Police or VOSA they only have to look at the mixed fuel and check the container to ensure legal compliance.

Therefore you have to follow the simple procedure of mixing at the petrol station, either by adding the oil, then petrol, or by filling the can with petrol, then oil, before driving away.

People living in social or rented properties are subject to the property owners specific conditions in their lease or tenancy agreement.

If this is carried in a vehicle or other engines fuel tank, such as an outboard, you are allowed to carry as much as the fuel tank will hold plus 25 litres in an approved metal container.
