Big drop in fuel mileage? Updated.
Hey guys new to the forum . Fuel mileage dropped over 100 miles per tank. Fuel light came on at about 330 miles on tripometer, 95% freewAy driving. Here is a little background on the truck. New injectors 1 year ago, full bullet proof kit installed 6 months ago along with new oem turbo, and new hpop.
Now the drop came right after bullet proof, turbo and hpop install. As I dont drive my truck but on the weekends, I wanted to give her a fighting chance before I talk to my tech. I have only put fuel in her 4 times since bpd install.
Any thought as to what could possibly be the issue before I take her in? I am going to do an oil change and get an oil sample to see if I have fuel in my oil ( the reason injectors were replaced to begin with.) but keep in mind this drop in mileage happened after the other installs 6 months later. I check airfilter, all is good there.
Anybody is welcome to chime in. She runs like a champ, and I dont smell anything out of the ordinary on the ol dipstick.
