[MazdaMatt]

...All between last thursday and this monday.

2 hours in my Mazda Protege from home to pick up my truck
6 hours to the race track in my truck
A few sessions at the race track
4.5 hours in the truck to my parent's house
2 hours back to where i keep my truck
2 hours in my mazda back home.

Truck - 160L of Deisel
Mazda - 40L of gas
Race car - 40L of gas

The crazy part is... i was trying to use as little gas as possible.

This truck is rediculous. I managed to pull off 19.5L/100km (12.5MPG). I Drove 85-90km/h on the freeway (100km/h zone, 120 standard traffic speed). I drove 70-80km/h highways (80km/h zone). I maintained 70 in the 60 zones to stay in top gear and 40 in the 50 zones to stay at low rpms. I tried to stay behind trucks on the freeway. I slowed down for uphills and sped up for downhills. I tried 2 neutral coasts and my tranny made horrible noises for the next hour when i was near the 3-2 downshift speeds. Is 12.5MPG that bad for a 5000lb truck with a 7.3L deisel and a 3-speed city-designed transmission?

The race car is a honda... 1.6L and has the fuel efficient gear ratios... bad for speed. I use as much gas in a day as the vette guys use in a single track session. I only left it idling once because i ran for 10 minutes with the temp guage pegged to the red (I had to cut open my bumper to make it run cooler after I put on an air dam)

The mazda I drove at 100km/h on the freeway, stayed behind trucks, pulse/glide where possible, coast down hills...

So... fire away... I can take it.
