  • awesome! what kind of fuel savings are you bring in since the conversion?

  • Not as great as I had hoped... But that is because I rarely drive more than 7 miles at a time, and biodiesel is expensive. It generally takes about 2 miles to warm up and 1 mile to shut down. However longer roadtrips are viturally free.

  • why u need to T coolant lines,, do u not cut coolant line one one end u cut on heat exchanger and other side u cut on outlet of heat exchanger, no T ! i seen loads of kits on truck n cars n no T's

  • I am very confused by your post. I used T's because every source I consulted before starting the conversion said that is the easiest way to it. I am sure there are alternatives, so if you could post some pics or a website with a better description that would be cool. Muito obrigado!

  • Thank you for all your posting this video and all the information on your website. It has been a big help in this process. I was just wondering about the Tank Heater, "Heater Core": for the tank I was wondering the best size and where to find them.

  • I got my heater core from a friend, but i am pretty sure that he bought it at an auto parts store for $30. The size is about 8x8 square, and 2.5 inches thick. The ports for the coolant are 5/8, so you'll have to be sure to get proper fittings or hoses (a 3/4 innerdiameter to a 5/8 innerdiameter) so everything stays tight. I think that the company that made mine is called Proliance International Inc, based out of New Haven CT.

  • why would anyone buy a german car? european cars suck. If I get an F250 diesel I'd definatly run veggie oil.

  • I want to see more veg oil conversion tips.

  • i'm buying an old diesel, do you have one in mind that may be easier to work with.

  • T's are used so that the vegoil heatexchanger is PARALLEL to the interior car heater and thus independent of the heater. OTHERWISE plumbing it liek you suggest it would be in SERIES and would only work when the interior car heater was on/flowing.

  • My first attempt at conversion I didn't use any Ts and did as you speak and just splice the heat exchanger into the existing line. After about 250 miles my water pump went out. The heat exchanger was keeping the water from flowing properly and it killed an already dying pump. I've used Ts since then, but I've found I prefer the "Y" type connections, where the outflow is split by a fork in the middle, it seems to force the flow in the right direction.

  • amazing! everyone should take a lesson from your innovation.

  • Hello Eric, I`m thinking of doing a veg conversion on a vw 1.9tdi. I was told that I could`nt do it if I have a Bosch fuel pump. And there is a convertor that you can get for around $60 so I dont need a heater(electric). Also how much diesel do I use with veg oil? Please can you help.
