This has all been very enlightening. I checked my tires and noticed that the pressure in the LR was quite low. I topped it off along with the others so let's see if that makes a difference. If not, then phase two will be checking the odometer for accuracy. (low hanging fruit) On 11/18/05,

I assume, you're actually calculating your mileage based on filling up the tank and doing the math of miles driven to gallons of gas used and averaging your mileage over several tanks or more in a row? If you're simply going by the low fuel light, my first thought would be if your low fuel light

First, unless you've fixed it already, it's somewhat likely the odometer is slipping and not recording the milage correctly. Second, you very likely have a worn timing chain unless it's been replaced. Fix the odometer, replace the timing chain, do a valve adjust (or valve job if the valves
