2007 Chevrolet Silverado 1500 LT1 4dr Extended Cab 6.5 ft. SB (4.8L 8cyl 4A)
My last Silverado was a 1999 (204k), I drove it for over 10 years so it took a while to embrace this one. I have the 5.3 flex and the power is great. I don't haul any big loads but when I go to pass the power is there. Before I bought, I looked at them all and still came back to the Silverado. If I took it easy I could easily get 20 mpg but I have found that I enjoy the power so 17.5 is normal for me. I get a little noise from the 'fresh air' doors and the OEM tires are gone at 40k, but I can say that I have no other complaints. Bottom line is I love it and would recommend it.
flex engine with power. Drops to 4cyl if power not needed. Funny to see it estimate 40mpg when i take it too easy.
The fuel warning says 'low' once it drops below a range of 50 (doesn't estimate miles past that). Not a great help.
