Track your gas mileage to monitor the engine on your McHenry car

Tracking the gas mileage of your McHenry car

is an excellent way to monitor how your engine
is running and detect problems.

When you’re ready to drive out of your driveway in McHenry, how do you know there’s a problem with your car? There are a number of clues:

The car won’t start
The car runs rough
There’s a repeated thump as you drive
There is smoke coming out from under the hood
There is one of many loud noises coming out from under the hood

There are other indications of a problem with your car. But, sometimes, the problem with your car isn’t that obvious.

If one of the symptoms listed above occurs, you could have a dead battery, an engine problem, a flat tire, a coolant leak, other engine problems or … well the list is long. You probably want to call a trusted auto repair technician in the McHenry area. But what if everything seems fine.

You might notice that the engine light is on. Of course, how many people drive their cars for years and years with the engine light on; they never have trouble, right? Actually, if your engine light is on, you should have the car checked out soon. It could indicate something serious with your car and, if the problem isn’t rectified soon, you could do serious harm to your car’s engine.

Another way to monitor the condition of your car is to track the gas mileage. When you keep track of your gas mileage, and you notice a sudden drop in the gas mileage, there’s a good chance that something is wrong.

Of course, if you left the car idling in the driveway to warm up on colder days this McHenry winter, that would effect your car’s gas mileage. But if the mileage drops without any plausible explanations you can think of, you want to have the car checked out.

Not only is it a good idea to have the problem fixed, and before the problem can cause further trouble, but you also want to save money on fuel; maximizing your gas mileage will save you money at the pump.

Recently, a driver noticed that the mileage on his diesel Volkswagen dropped from its usual 39-mpg to 26-mpg. That’s a precipitous drop. The driver brought his car in to Performance Unlimited where he learned that a backpressure valve in the exhaust system was sticking. All that was needed was to replace the part.

How to Track your Gas Mileage

To track your gas mileage is fairly simple. You need to keep track of the miles you’ve driven between fill ups and how much gas you used.

The next time you fill up on gas, write down the odometer reading. In the sample chart above, on Jan. 17, it read 75,372. Then, the next time you fill up with gas, write down the new odometer reading. Then subtract the earlier odometer reading from the new reading. This will give you the number of miles you drove between fill ups.

Now take the miles you drove between fill ups and divided by how much fuel you pumped at the time of the second fill up. This will give you your gas mileage.

Is your antifreeze safe from freezing this Richmond winter

You still have time to have it checked Well, there’s no denying it – winter tends to get chilly here in Richmond. We have to deal with snow and ice on the roads, scraping the same off our windows and windshield, and staying warm while we drive. Of course, you had your antifreeze checked before winter rolled into town. What?! You didn’t have your antifreeze checked before winter clamped down on Richmond? So, how’s your antifreeze doing? If you haven’t had it checked, there’s really no way of knowing, is there? This car has overheated in the middle of a Richmond winter. But, on the other end of the spectrum, the antifreeze can also freeze if it's not up to its job. Hopefully, you haven’t had a serious problem with your antifreeze already. If you did, you’d probably know. When antifreeze fails, it’s a potentially catastrophic condition for your vehicle’s engine. You could have hoses that have burst because of freezing antifreeze. Worse than that, your engine block may have crac...

Blocks of ice falling from cars in McHenry could cause accidents or damage

We’ve all seen those blocks of snow falling from behind the rear tires of a car when the snow rolls into McHenry . Fortunately, they’re just packed snow that will disintegrate under your vehicle’s tires as you simply drive right through them, right? Don’t count on it. Those blocks of snow are often packed so tight, condensed by the thaw-and-freeze cycle, that they’re anything but oversized snowballs . They’re often more like boulders. Hit one of those blocks and the collision between the block and one of your tires could send you careening off the road or into oncoming traffic. In some cases, they’re so solid you could pound them with a sledgehammer with little effect. They truly can represent a serious road hazard. The problem is that it’s difficult to tell how solidly they’re packed when you see them on the road, left their unwittingly by another driver. Either way, your best bet is to try to avoid them. But you want to be careful dodging blocks of ice in the road, too. You need...

Sap, Sun and Droppings conspire to attack your Richmond car’s finish

Who doesn't love summer time in Richmond? But this is also the time of year when sap, sun and droppings attack your car's finish. It’s a beautiful summer day in Richmond, IL, so you take the car to Richmond Carwash and give it a thorough cleaning. Or maybe you go for an entire detailing. On the other hand, you grab a bucket, sponge, brush and appropriate cleaners, drag the hose out to the driveway and wash the car yourself. Before you know it, the car is clean and shiny, almost like the day when it was new, right? But what does Murphy’s Law say about washing your car? Inevitably, if you wash your car, you can count on rain. It almost seems like, as soon as you give the car a good bath, the rain clouds start plotting and changing course to head straight for your Richmond home or wherever else you park your car. Let’s imagine that Murphy takes a pass when it comes to applying the Law of clean-car-precipitation onto your vehicle. You have the car washed but it doesn’t rain. You’ve...
