Will a fuel filter improve gas mileage?
I have a 2001 ford expedition. It usually get Ok gas mileage. But lately even since I've gotten my oil changed Gas mileage has been attrotious. Like it uses a quarter tank of gas and I've only been like 20 miles. And it was mostly highway. Sears did say I needed a fuel filter but I heard that doesn't really help gas mileage. It has just over 96K on it. I've never changed spark plugs, fuel pump, air filter in forever if I ever replaced it in like 14 year I've owned it. I can't remember. Auto zone told me to check 02 censor but the check engine light isn't n on.I'm lost really. I just want it to get the mileage it used to get.
The fuel filter (although it couldn't hurt to do) will not change your gas mileage at all.
Correct Tire pressure, new air filter & new plugs all will make an improvement in your MPG.
If you are on the level, Maybe its time to replace your fuel filter, air filter, spark plugs, start doing regular maintenance and your car may run better and mileage may go up.
Fuel filter won't affect MPG, but worn plug will KILL your MPG
No but it is great for your engine

- Does acetone increase gas mileage? I've been trying to convince my dad to get buy me this 2004 Ford F-150 XLT with 5.4L V8. I really like this truck because the 5.4 produces 300 HP and my crush really likes F-150s. The reason my dad won't buy is because it gets 13 city and 16 highway. So i was wondering if acetone really does increase gas mileage and also without harming the engine. SERIOUS ANSWERS ONLY Please
