I have had my fuel filter changed and loss about 6-8 MPG
I want to look at the fuel filter and check it out, but I have no idea where about it is. I also smell gas at times so I think that there might of been a gasket or a loose nut or something of the sort. Where is the filter at? This is on a 1990 Chevorlet Lumina. Thanks.

Thanks for choosing FixYa and welcome. Plugs will help your fuel mileage a little. Also, make sure the vehicle is in allignment. Make sure the tires are proper size. You may need to have the fuel system cleaned. Change your fuel filter and clean the system out. Check your drive belts and make sure they are not wearing. The allignment is big, can cause a loss of 2 mpg. You are correct though, plugs will help.
don't know about the MPG it could be a lot of things. I have a 2001 Jetta TDI. You should NEVER change the oil at 3K miles. VW recommends 10K miles for a reason. The Synthetic oil has additives to remove varnish and it does that but it needs some time to replace the varnish and properly protect sensitive engine parts. 3K is oil changes are not a good thing for a TDI......Just use the right oil and change at 10K
Give it a tune up. Ford's run tough, but they still need a little love now and again. New fuel filters, new air filter, new spark plugs and wires, new injectors, new timing and accessory belts if they are really worn. An oil change and transmission fluid and filter change will help as well.
Also, check that your tires are full of air. Flat tires, even a little bit, can cause a drag on the engine and give you bad mpg. Carrying a load can also cause drag, so try to keep the trunk free of unnecessary items.
check the timing with a timing gun.if the timing is too retarded there will be a huge power loss.The catalytic converter could be plugged,if there is a reduced exhaust flow that is a good possibility.A quick but noisy way to tell is to undo the exhaust before the converter and see if power returns.here is a list of other things to check...spark plugs,cap rotor and wires. Do a compression test.Then the air filter,clean the throttle body. Check the fuel pressure and change the fuel filter.
could be your spark plugs... your air filter... even your fuel injectors could do that. clean the fuel system with a complete fuel system cleaner from autozone or whatever and check/ change your spark plugs. also check your air filter for clogs or too much dirt
Your car needs a tune up, including the air filter, fuel filter and spark plugs. It's also worth while checking for a faulty/stuck brake caliper, after you've been on a longish drive go around and feel the wheel rims if one is alot more warmer than the rest then you also have a faulty brake caliper.
