Hi all,
I bought my big old diesel suburban to move and tow what ever I need.
Its not built for speed
or off roading (2wd).
I mod for power and economy, which is easy to do on a diesel.
I got the truck in 2006 and started cutting waste vegetable oil into the diesel fuel almost right away. At the same time I started modding for power and economy, over the years from 2006 to 2010 I did several mods to pick up between 5 to 6mpg. Most of those gains came from intake and electric fans.
Starting in 2010 I tore the engine down and nothing was off limits. I built the engine back up with just about every affordable power and MPG mod I could think of and I am working on doing alot more.
Not much is off limits.
A 1984 diesel suburban that gets 30mpg is not out of the question.
