Do you mix it before putting it in the tank or after?
Am interested in the bio route and even have a donor for used oil (a local chippy) but wouldnt have a clue where to start
Cheers biolandy will have a read of those sites tonight.
so if i want to use supermarket oil do i just pour it into my tank when i have put some doozil in? or should i mix it before adding it to the tank?
As Sean says,petrol is a better solvent for thinning veg oil,up to 10% petrol is typical for these temps at the mo.
