I have a 1997 Ford F350 XL crew cab and I am trying to improve the MPG's. I know a lot of people say "good luck with that". It has the 5.8 Liter 351. I haven't done anything to do it yet. I was thinking of buying a less restrictive air filter, changing plug wires and spark plugs. What else do you think would help? It gets pretty good gas mileage now considering it has the 5.8. 10 highway 14 city. It has 126,000 miles. I do believe it has a 4.10 gear in the rear end (truthfully idk but I'm guessing). I am not sure if they even ran a 4.10 gear in the 1997 trucks. I know it's crazy it gets better gas mileage in the city but that's something I'm trying to understand. As long as I am cruising around going 45-55 mpg I am getting my best gas mileage. 65+ I might as well put a hole in the gas tank.
The only reason I bought this truck was to use with my Lawn Care business. Naturally in business sense the less money I spend the more I make. That's one place I am trying to cut corners. It's possible if I mow all of my yards I could travel 120+ in a day. Yes, I agree that's way to far apart. The two that are the farthest apart live in Ritzy neighborhoods so I am hoping to pick up a few yards to make It worth my time. Anything will help. Thanks!
