i love threads on veg oil and people saying you carnt use it on modern stuff we look after stuff at work that run 100% like golden west and sony daf even ok 100% and golden west run it there LF65 which is commen rail too its all in the tank heater system from what i can see! if the oil is heated and the same viscosity as diesel and totaly clean it wont clog any thing (put it in thick and cold with shit in it you will obviously have problems) the only daf aids we have with golden west (mcdonalds transport company who make there own from resturant oil) is in the cold if the driver dosent turn the tank heater system on or there is a fault with it
