I know this question is going to sound very odd to our cousins on the other side of the pond but over here in the good old UK, fuel has reached stupid prices (£0.90+ a litre), so I'm thinking about doing daft things to my car.
So I just wanted to see if anyone else out there had tried this.
My "victim" will be my 1996 E36 325TDS. Initially I'm planning on trying some new vegetable oil, but eventually if all goes well I'm thinking of using old oil from the local chippy. Obviously filtered to remove all the bits of chip!
From the reading I have done, there are two routes.
1) Put some additives in the oil to break it down, then run the car unmodified. 2) Leave the oil alone, but run a 2 tank system. Diesel to start and warm the engine, and flush out at the end of a drive, and a heat exchanger between the water system and vegetable oil to get the oil thin enough to run on.I'm planning the heat exchanger route as it means I don't have to mess about leaving gallons of oil undergoing various chemical treatments for several days before it can go in the car. I'm not organised for all that, I'd like to be able to buy a bottle at Tescos and chuck it in the tank! (Obviously this wouldn't be the normal route as it's expensive, but it means the car is more flexible).
So what do you guys think? Any one with first had experience of veggi oil in an old injector pump style diesel like this?
Cheers
