Apart from your time it hasn`t cost you anything so personally I`d be VERY reluctant to put it in anything with an engine in it that if it went t*ts up ( straight away or over a period of time due to the wrong fuel) it could actually end up COSTING you money to put things right. Even a heating boiler could cost money to put right if it didn`t like the wrong fuel...After emptying out a fair few friends & relations vehicles after they have mis/fueled them I'm left with quite a few drums of petroly/diesel mix, just wondering if anyone's been able to find a use for it other than lighting fires .
I did try some in the strimmer but I added oil as if it were straight petrol and I was almost overcome with fumes after a few minutes use! I had to play around with the choke to keep it running, almost completely closed and it had to rev flat out unless it died. I wasn't brave enough to add the mix straight to the tank without oil just in case it seized up could maybe try reducing the oil content from say 50:1 to maybe 80:1 perhaps
It is very frustrating having a load of expensive fuel "mix" and not being able to put it to profitable use but it could prove very COSTLY trying....
