Mailbag: Making Gas Mileage Count

Got questions? We’ve got the answers—Mondays when the Summit Racing tech department tackles your automotive-related conundrums. This week, we’re getting you ready for travel season by sharing some tips on enhancing fuel economy.

K.G. • Groton, CT Q: In my younger days, I was constantly ordering racing parts. Now that I’m older, I need some reliable parts for my new project—a 1988 GMC 25-foot American Class C RV. I plan on driving it all over the United States so I need to stretch every gallon of gas as far as I can. What affordable upgrades should I make that will increase my gas mileage? I’m looking forward to your response so I can hit the highways!

A: Start making mileage count by upgrading to synthetic oil in your engine and rear end. Most synthetic formulas will also provide superior component protection and last longer than conventional blends. For more noticeable fuel economy gains, upgrade to a high-flow air filter, intake manifold, and headers. The unrestricted airflow will help ease the pain at the pump. A quality transmission cooler can also add mileage due to the maximized heat dissipation. These DIY upgrades can be made all at once or little by little as your budget allows, and any combination will result in more miles between fill-ups!
