I just drove my 2001 Tacoma extracab TRD, 3.4L, stock tires and suspension,
211.000 mile, from Wisconsin to New Jersey shore and got 20.82 miles per gallon!
The only mod that may have helped me is my deck plate mod with baffle.
I used cruise control at 62 - 63 mph.
I think we are still using winter blend gasoline 87 octane. This mileage is a first for me during winter and early spring!
I can't wait for my summer two month camping trip out west! Should get even better mileage!
Anyone else get this mileage on winterblend?
