Houston Biodiesel accepts used cooking oil for responsible disposal at any time during the year.
Houston Biodiesel is currently offering pump biodiesel at well below the price of diesel fuel. As such we're getting a lot of new biodiesel users. You don't need to be a biodiesel expert to use it as a fuel. All you need to know is that you use it just like diesel fuel. Don't complicate it. Just fill up your tank and drive. No vehicle modifications required. No voided warranties.
Biodiesel pump price is $2.099/gallon - taxes included
