Nothing new, but:
Every two weeks, Etta Kantor drives to a local Chinese restaurant to fuel her blue Volkswagen Jetta. She calls ahead and the owner knows to put aside a few buckets of used oil just for her. At home, Kantor uses a colander and a bag filter to remove water and any food particles.
The vegetable oil is then poured into a 15-gallon tank that sits in the back of her Jetta, where a spare tire would usually be kept. With a touch of a button, located above the radio, Kantor can switch from diesel fuel to vegetable oil in seconds.
"Oh, I zip around town, go fast on highways. It's not any different," said Kantor, 58, of Weston.
Restaurants have to pay to get rid of their old vegetable oil and are happy to give it away for free.
