I calculate that average fuel economy over 35k miles is at 17.1 mpg. I buy mostly the cheapest Sams or Cosco gasoline. Some other information I take from this data is that:
- Maximum range was 367miles at 22.3 gallons
- With the exception of the first fuelup, my Trooper has never given me less than 15mpg with the range consistantly between 15 and 18mpg.
- Fuel economy jumped to over 18mpg in the Sept-Nov 2001 time frame. The odometer was almost 30,000 but was after an alignment where tires were rotated in an "X" pattern. But, about 2 months later, the fuel consumption fell back closer to its overall average consumption level. Be interesting to see what happens after the 30k service.
So far, an I will knock on wood, there has been no major repairs and my Trooper uses no oil. I'm using mostly Havoline oil but wonder what would the numbers be if I had used Synthetic oil.
Also, my Trooper had 20 miles on the odometer when I purchased it. I know at least 10 of those miles was me test driving it. Thus, I know it was never abused:-) It ran with the break in oil to 2,676 miles. I remember keeping the speed down below 60mph, no quick accelerations, and babying my Trooper the first 1,000 miles. After that first 1,000 miles, it regularly was driven 65-75mph while on the Interstate. My Trooper uses hardly any oil between oil changes which average just under 4,000 miles between oil changes. I do very little offroad driving. I do pull a 10' trailer occassionally carrying lumber, mulch, etc.
I think this data indicates that my Trooper is a pretty good example of Isuzu quality and I wonder if we can deduce a break in procedure that will cut down on later oil consumption and improved fuel economy.
