I've had this 82 mercedes benz 240d for over a month. The previous owner ran it on straight veggie oil down in Southern California. I put a few tanks of diesel and one of biodiesel in it for traveling up to Spokane WA. I then put 5 gal. of clean cinnamon bark oil that I'd acquired along with the car(I have no idea who gave him that stuff) into the tank. Immediately the weather turned colder...I drove around the block and the car proceeded to stop running. I changed the conversion filter and the inline filter. I changed the main filter and added 5 gallons of bio-diesel. All these remedies have improved the situation from the car only turning over to starting but it continues to choke out after less than a minute. I put the car in a garage(outside it is still 40-55 degrees in the day) and have gone out to sit and try to keep it running but it keeps dying.
I've run out of ideas. I'm not a mechanic. I've read a ton on veggie oil and biodiesel and I'm wondering if I just keep trying to start it if it will eventually go again or if I did some kind of bad damage...
p.s. the conversion on the car was done professionally but was, I believe mainly for the temperatures of San Diego. no second tank. I thought I had the temps to still run that veggie oil.
thanks
