Everyone wants to get better gas mileage in their vehicle, but not everyone really understands how to make that happen for real. So they focus their efforts on one or two areas, without ever realizing that the best gas mileage improvement plans have five different angles to them, or spokes of a wheel. Sure, focusing on just one facet of the gas mileage equation will usually get you some meager results, but it’s not until you address all five facets of the equation at the same time that the much higher gains in gas mileage are seen. Let’s look at each of these puzzle pieces briefly.
1. The Driver Influence. Believe it or not, the driver’s own driving style will affect the vehicle’s overall gas mileage in some pretty big ways. When you drive around town, you always get lower mileage than you do when driving on the highway. Treating every stoplight like it’s the next biggest race of your life, and stopping suddenly too at the next light, both cut into your vehicle’s overall gas mileage. But simply driving at or under the speed limit, choosing a route that has fewer stoplights along it, coasting to a stop at each light, and being content to not be the first vehicle off the starting line when the light turns green, all these will noticeably improve your gas mileage.
2. The Actual Vehicle. Is the engine all tuned up right? Are the tires inflated correctly? Is the engine oil still within spec? Are you taking care of your vehicle? Are you keeping the paint job good? Good maintenance is one of the easiest ways to improve your mileage back to near (or better than) factory specifications.
3. What Your Engine Burns. High grade gas will get you farther down the highway than low grade gas will. And contaminated fuel will cost you in repairs as well as lower mileage. Modifying the engine’s fuel to burn better, and buying high quality fuel to start with, both are excellent ways to get better gas mileage.
4. The Air. Believe it or not, there are also ways to improve the air flow going into the engine, and likewise improve your gas mileage. Cool air can carry more Oxygen in it than hot air can, and can expand a lot more when it is heated inside each cylinder. Humid air also absorbs more heat than dry air does, and thus expands more too inside each cylinder (also better efficiency). Clean air promotes better fuel combustion in each cylinder than dusty, dirty or smoggy air does. Pressurized air going into an engine contains more Oxygen in it than unpressurized air. Etc and so forth.
5. The Complete Exhaust System.There are even ways that you can tweak your exhaust system to improve your gas mileage. You can do things like oversize all of your exhaust pipes, oversize your catalytic converter and muffler, add a tailpipe turbocharger, or even recycle the extra heat found in the exhaust system in one of a couple of different ways, all to improve your car’s mileage.
By emphasizing a “whole-car” approach when we address the five different aspects of the ‘get better gas mileage’ problem, we can improve the mileage of almost any sized combustion engine that we touch, in substantial ways.
