How to Improve the Efficiency of Your Classic Car

Posted by: Bell Performance

Classic cars are a labor of love for auto enthusiasts. And while there are some big benefits to owning a classic car, there can be a few notable drawbacks as well - notably, how inefficient they run.

5003287097_32f22f4938_nYes, classic cars are gas-guzzlers compared to the fuel-efficient models that are rolling off the assembly line today.

And while it's next to impossible to modify your classic so that it gets 40 mpg, there are certain things you can do to improve its efficiency. Here's a look:

Overdrive Transmission

If you want to increase gas mileage by up to 50 percent, consider adding a modern overdrive transmission to your classic car. It's a bit of an expensive endeavor, no doubt, but it can pay big dividends in helping you save at the pump, especially if you enjoy driving your classic car.

Fuel Additives

Fuel additives can help keep the engine cleaner and thereby running better for the life of the car. And to boot, they aren’t too expensive.

Lower Suspension

Another costly upgrade, but many cars have a tendency to ride high. Replacing the original suspension with one that helps your car ride lower to the ground will translate to more mpg. That's because it will displace less air, increasing cruising efficiency.

Fuel Injection Systems

Consider replacing the carburetor with a fuel-saving fuel injection system to increase the efficiency of your classic car. Stand-alone systems are available from leading automotive manufacturers. 

Attention to Detail 

Unquestionably, one of the best ways to maintain - and increase - the efficiency of your classic car is to ensure that it's properly maintained. 

Stick to a maintenance schedule and consider making improvements (i.e., ignition system, new spark plugs, etc.) when need be. Sometimes it's the little things that make the big difference. 

You love your classic car. Just because you own a car that was built decades ago doesn't mean it has to run like it was originally built to. Adding the likes of fuel additives to the gas tank, a new overdrive transmission, and replacing the fuel injection systems are a few of the keys toward a better running car.
