Hi,
I have changed nothing but they type of fuel i use from Reg diesel to 20% bio diesel. I was averaging 35 MPH and now it is 30 MPH. I did change the fuel filter after the first tank of bio. Separate question, Is there any thing to check out ( no heavy mods please) to increase my mileage to be closer to 40 MPH?
Thanks.

Losing a little mileage with bio is fairly normal. Is this around town mileage? Manual or auto?

Hi there! I hope you can get your MPG back up! Have you checked out your oxygen sensor? That could decrease mileage. Have we met you yet at a GTG? Bandimere just hosted the Bug-in and there's a show at Ed Carroll Motor Company in Fort Collins August 26. Let me know if you can come! :)

No O2 sensor on the 01. That type of mileage is fairly typical of the automatic if that is what you have. If yours is manual then you probably have an issue. Check snow screen, air filter, fuel filter, engine timing, turbo boost (actuator functionality).
