Veggie Car Success

Yesterday I drove the Mercedes to Coosa County. UPS delivered the last part (the coolant pump) last week and I had installed it so the 'veggie car' was ready for a test. Just below Alabaster, the operating temp had gotten high enough that I felt comfortable switching to vegetable oil. There was no noticeable change in operation. I stopped at the Calera exit to look under to hood to make sure everything was ok. Then I walked around to the back and checked the exhaust. I can't say that it smelled like 'french fries' but it definitely had that hot cooking oil smell. I drove on toward Clanton and switched back to diesel at the Lake Mitchell exit. The maiden voyage was a success.
