Not cars I know, but and engine of car parentage
My Grandad has an allotment/freehold where he has some sheds and out houses paraffin, he uses a small diesel engine of dubious parentage (ex car - but what is anyone's guess) to run a small generator/alternator set, which in turn power some lights, kettle and what not ( nothing too frequency sensitive).
Anyways, he has been using red diesel in it, all kosher as its hardly on the road, but he has about 50-70litres of paraffin from when he used to keep greenhouse heaters running on it.
He want to put the paraffin in the engine, but I have heard that using things other than diesel can cause damage to the fuel pump. But now I have googled for it I can only seem to find issues with, bio-diesel and unmodified veg oil causing probs....
Should he be ok to put the paraffin in?
TIA
