... 3.0 merc td? aka a GC?
Anyway you should hand calculate your mpg and find your error, there will be error. Get your mileage error with gps or similar also. (common on kj/crd maby not on GC)
As far as remaining, goes, it's a function of your mpg, and cap of your tank, neither of witch are likely to be accurate. your doubly screwed.
Let me give you an example. Evic says i'm averaging 33 mpg, my fuel light comes on (0 miles to empty) i continue driving 100 miles. When i fill up i add in 22.2x gallons. crd kj is 20 gallon tank. YOU tell me.
Pay attention to the sweep of your fuel gauge. In my case, it sweeps below the e, when off, and i figure that's EMPTY. It also sweeps above the f.
It's a cluster of fun. Bottom line is they are all different, every freaking vehicle. Trial and error is how you get there. Carry a 5 gal tank of diesel with you and drive it till you loose prime. I hope you have a lift pump, also i would not make a habit of doing this, IP's don't like to run dry, no fuel = no lube.
But what if next time your fuel light is on, you think, well i went 100 mi last time no problem. So you shoot for 80 mi, you run out of fuel. Headwind vs tailwind 26 mpg vs 33. Not good.
Here's something else. I typically fill up within 1-5 miles of my fuel light coming on. Sometimes this is 17 gal, sometimes it's 20+ Yeah.
I figure your probably going to want to stop within 600 miles anyway (30 mpg @20 gals), may as well get fuel while your doing that. That's eight hours at 70 mph. (30 mpg possible at 70)
