Got access to wvo and was wondering what I have to do to be able to run my 200tdi on it?
I run my defender on veg oil. I fitted a second tank for diesel, a plastic 20ltr container, and put the veg oil in the main tank. I have a set of valves to switch between the two.
The veg oil goes through a heat exchanger run off the heater water pipes and into the injection pump. I only switch the oil when the engine has warmed up. The fuel return is taken through an electric thermostatically controlled heater to keep it warm and sent straight back to the pump rather than back to the tank. I switch back to diesel a few minutes before turning the engine off. This means I always start on diesel as it's a pig to start on veg oil when it's cold.
Heating the veg oil keeps it at around the same viscosity as diesel.
I'd rather go through the one off install than balls up my injection pump.
I ran that way for 2 years on my 150 mile a day commute without any problems. Every so often I'd do the run on diesel alone.
The waste oil I poured into rain water butts through 2 layers of old bed sheet. Then let it sit for about three weeks. I then siphoned off the good oil from the top leaving the crap at the bottom.
You need to change the fuel filter more often. I also have a finer filter in the vehicle for the veg oil.
My supply dried up as the landy has been off the road for 2 years, gearbox not engine. I'll probably just buy clean oil now rather than have a shed full of water butts.
That sounds like a well thought out set up on your engine there mate
