Took my vehicle for 2nd service at a Toyota dealer last month, just under 14000 miles. Since returning fuel consumption has fallen drastically. Vehicle has 2” lift and BFG K02’s fitted. Previously was averaging 27 to 28 mpg since fitted, but now getting 23 and it is getting worse. In addition when lifting off and coasting down gradients, where previously it would maintain speed or accelerate, now will decelerate.
Anyone any ideas what the dealer could have done?
