If you’ve noticed the air around Carlsbad has been easier to breathe lately, you can thank Taylor Knox. Homeboy recently had the crew at Grease Not Gas convert the diesel engine on his 2008 F250 to one that runs completely on vegetable oil. At a price of around $3,700, Taylor’s new 37-gallon tank can make a run up to Maverick’s and back with a little juice left over. As well, filling up has also gone from a hassle to pure pleasure, as local breakie hot spot Hill Street Cafe in Oceanside lets him chow down on home fries while the day’s grease is transfered to his ride, for free.
