John’s Auto Care: Good Service And Good Fuel Economy

Most of our Louisville clients want to save on gas and seek our advice on improving fuel economy. At John’s Auto Care, we are frequently asked, however, just how much money Louisville motorists can actually save.

Well the US government has a website dedicated to helping us use less fuel. It presents the cost savings in a way Louisville car owners can relate to and is relevant for all vehicles. Let me give you an example: Having your family car engine properly tuned, can save up to 4%. If you’re paying three-fifty for a gallon of gas, you could save fourteen cents a gallon.

In today’s John’s Auto Care post, we’re going to talk about several things you can do to improve your family carfuel economy driving around Louisville. We’ll tell you the potential savings per gallon of gas at three dollars and fifty cents, and we’ll show a graphic that also shows the savings at three and four dollars.

The next item is replacing a clogged engine air filter. Your engine needs enough air to burn fuel efficiently for the best economy. A clean air filter means you get plenty of air. The fact that the air’s clean protects your engine. That can save you up to ten percent or thirty-five cents a gallon.

Fixing a faulty oxygen sensor can improve economy by up to forty percent. That’s a whopping dollar forty in savings per gallon. Bring your car to John’s Auto Care and we’ll check your oxygen sensor.

Chances are that if your oxygen sensor is kaput your check engine light will come on. Now, there’s any number of things that could cause your check engine light to come on besides oxygen sensor problems. But if it’s on, get it checked out as soon as you can at John’s Auto Care.

Here’s an easy one. Inflate your tires to the recommended pressure. That could save you three percent or eleven cents a gallon. Even a little drop in pressure will cost you at the pump so check your tires every week.

Your family car manufacturer has recommended a specific weight of motor oil. The recommendation is based on engine design and will give you the best protection. Using a heavier weight could cost one to two percent in reduced fuel economy, or up to seven cents a gallon.

Here’s one that’s free: Take it easy when you drive. Aggressive driving (we’ve all seen this on Louisville roads), rocketing away from stop lights, standing on the brakes, punching it for lane changes – really takes a toll on your fuel economy.

Cutting out aggressive driving around Louisville can save five percent or eighteen cents a gallon. Now on the highway it gets really costly: thirty three percent or a buck sixteen a gallon. Think about that.

DOLLARS PER GALLON$3.00$3.50$4.00
DRIVE AGRESSIVELY – MIN. 5%.15.18.20
DRIVE AGGRESSIVELY – MAX. 33$.991.161.32

 A related item is exceeding the speed limit. For example, if the speed limit is sixty miles per hour an additional five miles will cost seven percent or twenty-five cents a gallon. Fifteen miles per hour will cost you upwards of eighty cents a gallon.

DOLLARS PER GALLON$3.00$3.50$4.00
SPEED LIMIT – MIN. 7%.21.25.28
SPEED LIMIT – MAX. 23%.69.81.92

The last thing we’ll talk about is excess weight. Our family cars tend to accumulate a lot of things and the weight adds up. Clear out the trunk and only haul stuff when you really need it. For every one hundred pounds you can save two percent or seven cents a gallon.

Sorry honey, your brother can’t come with. It’d cost an extra thirty cents a gallon.
