So, I bought my wife a brand new 2006 VW Jetta TDI last year and wanted to share my experiences with using a diesel. One of the reasons we bought a diesel is so we can use biodiesel, plus I want to switch to a waste-oil system when the car is paid off. (On a side note, buying cars in Hawaii is a joke. Even though we were able to talk the dealer down nearly $3000 from the original price, we still paid more than $2000 more than the “street value” as listed on several car shopping sites).

We use 100% biodiesel in our car. For those who don’t know, biodiesel is made from recycled vegetable oil, which isn’t really that strange. The original diesel engines were made to run on peanut oil, if I remember correctly. And even though nearly every diesel car maker states you can void your warranty if you use anything greater than 5% biodiesel blends, it’s mostly a lie. > more <
