The top selling feature for cars on the market today is MPG's or "Miles per Gallon". On average standard economy size cars with 4 cylinder engines offer 25MPG, while larger 4 door 6 cylinder sedans are offering 20 MPG. This seems like decent gas mileage but is it really? And don't even consider a SUV will offer good gas mileage unless it's a hybrid. Generally, fossil fuel SUV's average less than 15MPGs, which is very discouraging for people who have them! But what is good gas mileage and how do you know if your car offers it? How can you get better gas mileage.
Getting Good Gas Mileage Is Your Responsibility
To put it plainly, what is considered good gas mileage is less gas usage for a greater per mile distance. For example; 25MPG equates to a travel distances of 25 mileages per 1 gallon of gas. But this doesn't necessarily mean that's good, especially when considering Hybrid and electric vehicles offer 40-50 MPG on average. Conversely, the MPG per car is contingent upon on a number of underlying factors in order to be considered good gas mileage. When considering what good gas mileage is, be sure to factor in these 7 very important elements. You may discover you're not getting good mileage after all!
7 Ways to Determine Good Gas Mileage
• Type of Vehicle - most often the type of car determines if it has good gas mileage. Basically smaller engines offer better gas mileage than larger vehicles. This is because of an engine size verse vehicle weight factor. The smaller the engine the less weight it is required to carry; therefore the less energy (fuel) it requires to operate. Quite naturally the opposite is implied in terms of a larger engine and body frame.
• Type of fuel used- understanding the different types of fuel required to operate a vehicle will help to better determine good gas mileage. For example; diesel fuel burns faster than unleaded fuel over a shorter period of time.The same is implied when factoring in the fuel sources for hybrid and electric vehicles, which draw their fuel source from more viable methods that offer a better distance per gallon.
• Fuel octane - Most cars run off of unleaded gas right! But do you know what the specific choices in unleaded octane values like; 89, 90 and 91 mean and why the cost varies between them? Basically the octane values determine the rate gas burn base on the fuel contraction to additive ratio. Therefore higher the octane the slower the burn. In this case the extra 75- 90 cent you think your saving at the pump can equal poor gas mileage on the road.
• Type of driving condition - A cars average MPG is factored on two specific types of driving condition; Street and Highway driving. It's standard practice for manufactures to point out the differences in street gas mileages from highway gas mileage. Basically cars give better gas mileage on the highway than city street conditions. Typically the gas mileage is 3 to 5 miles more than street driving. So what is considered the best gas mileage for a car is how much more highway gas mileage is over street gas mileages.
• Rate and distance - Another way to determine if your car has good gas mileage is by calculating your daily driving distances and average rate of speed. For example; the faster you drive to get to a shorter distance will equal the average amount of gas mileage it would take driving the legal speed limit traveling twice the distance. Essentially driving slower will produce good gas mileage in the long run!
• Routine Repairs - Typically a car runs much better when the engine is in tune and properly lubricated. Keeping up with routine oil changes, tune ups and fluid levels will make your car run more efficiently. In the end, keeping your car in good running condition gives off better gas mileage. This is because the car doesn't have to work as hard to sustain optimal operational levels.
• Tire balancing - Very few people realize that maintaining good gas mileage is highly dependant on proper tire balancing and tread conditions. A good well balanced properly treaded set of tires offers 2-4 miles better gas mileage than poor unbalance tires. Again! The cars tire condition is factored into optimizing the level of work the vehicle has to exert to maintain performance.
