Daryl Hannah is a fan of alternative fuels but she didn’t want to give up her big Chevy Suburban vehicle which she uses to tow a horse trailer and her four horses at home in Colorado.
So, according to People magazine, she came up with a clever solution.
The actress bought a modified SUV (Sports Utility Vehicle) that runs on used vegetable oil.
There are around 150 of these cars on America’s roads and typically they have regular diesel engines which are converted using special kits costing between €346 and €798.
Hannah, 42, gets her fuel supply from fast food restaurants which give her vats of used oil for free.
The only drawback is that when in use the vehicle tends to smell a bit like a cooker.
Hannah, whose movies include Splash, Roxanne, Steel Magnolias and Grumpy Old Men, is currently shooting director Quentin Tarantino's new film Kill Bill which also stars Uma Thurman, Lucy Liu and Samuel L Jackson.
