Wow the best I can get is 290 ish, and i do a out 75-80% hwy driving.What do you have done to the car.
2 lifters replaced, valves adjusted, timing belt done, all at Lexus,
And I cleaned the k&n cai filter, filled up with 91, threw in some injector cleaner from time to time, reset my ecu
At Lexus though they told me my engine is so damn clean inside, that it def had no problems with oil changes and the owner before me took good care of it, although I'm baffled at the 2 bad lifters the kid that sold it to me did to the engine...
I'm a doubting Thomas now. I don't believe it at all, especially with 60% highway, 40% city driving. I need to see a pic showing 429 miles and see where your gas hand is at. You must drove the car until you ran out of gas lol. What K rating is your hid kit low beams? 5-6k? Sunroof open while it's raining...you're a bad man lol
Full Tank= 429+miles GS400!!!!
