What problems can i expect if im running my gt tdi 115 on veg oil??

[jonnyoutram]

i do thin it out with kerosene or diesel and filter it... i bought the car to run it on veg oil after having run a mk3 on it for 6 months.  now i have been hearing mixed reviews.  some ppl say it should be fine and some say i should drain the tank!!!    

if it is a problem... what problems should i expect??

smells great depending on where i get the oil... this week its prawn cracker flavour!!

costs about £2 per tank

Buy a crappy landrover tdi if you want to run a vechile on veg oil, not a mk4 golf

when you reach 88mph does it go back to the future?

No diesel can run on cooking oil

yes its the common rail diesels that tend to have little problems - the PD diesels don't really like it tbh 

i've never seen someone run theirs long term in all honesty

Not a case of filling the tank with Veg oil, it needs heating to be combustable, most vehicles i have seen on veg oil use diesel to start the car then switch to a seperate tank and feed system with pre heaters to get the oil upto temp, switch over to vegetable oil when at normal operating temperature, run all day, if you stop during the day for an hour or so you do not need to switch back to diesel because the engine will still be warm, at the end of the day switch back to diesel, run for a few minutes and switch off, this ensures engine can be started next morning on Diesel.
 running cold veg oil through will make your golf last about 6 months if your not using the 2 tank method
