Been driving it and enjoying it, surprisingly. As for plans:

POR-15 (Rust Prevention Coating)
Front Air Dam
Rear Wheel Arch Covers
Partial Front Wheel Arch Covers
Oil Pan, Transmission Pan and Fuel System Pre-Heaters (The last one's for winter use)
Amsoil Oil Bypass Filtration System (I'm not sure this will increase MPGs, though it'll keep the oil cleaner if it works as advertised.)
Power Steering Fluid Flush (The first flush didn't clear out all the brown burnt fluid. It did help though, and I imagine may increase MPGs a bit if old fluid has been putting extra strain on the system.)

Can this vehicle run on 100% Biodiesel without modifications? I realize that may plug up the fuel filter if I do it all too quickly, since Biodiesel loosens unburnt petrol fuel.

I'm also wondering if I should put in a filtration kit for the engine coolant. Does that increase MPGs? I was reading the sites that sell those kits say there's something leftover from the manufacturing process of a Diesel engine and a filtration kit can remove that.

Are there instructions on here about keeping the SG2 on while EOCing with a manual transmission?
