I recently bought my first Toyota in the form of a 2006 Tacoma 4x4 Double Cab Short Bed. I must say that I do love this truck. However, I am a little concerned with the fuel economy and was wondering if what I am experiencing is "normal."
My truck now was 1800 miles on it. The first tank of gas was 87 Octane and I got 18.5 mpg on just highway driving (50-65 mph). The 2nd tank was 87 again, but this time I got 17.5 Third tank at 87 was 17.5. I thought I would try the premium octane (91) next tank and this time I got 16.5. Next tank I tried 89 Octane and got 15.5. The currently tank of gas I am on, I filled back up with 87 Octane. My fuel gauge (which is just a "gauge") is just above 1/4 tank left and I haven't even hit 200 miles yet! I mainly drive a mixture of highway and city driving. I fill up at the same gas station every time.
Is this normal?? The rating for my Tacoma is 17 City and 21 Highway. I realize these are just estimates, but everyone I know that has a Toyota vehicle typically gets well within the estimated fuel economy if not better. I am frustrated because I got rid of my Chevy S10 that got 16 mpg for a Tacoma hoping to get slightly better.
Please respond and let me know if this is normal. Bottom line is that most cars/trucks get close to 400 miles on a tank of gas and my Tacoma is getting only a little over 300.
Should I take this into the dealer???
