Don’t let the cold starve your engine – refuel often



An internal combustion engine, which, unless you’ve purchased a new electric car, is probably what you drive, must have fuel in order to run. If you let the tank run dry, you’ll find yourself coasting to the side of the road with an engine that’s stopped running.

In the winter time, it’s a good idea, not only to make sure you have gasoline in your tank, but to keep the tank from becoming too low on fuel. The reason this is important is that air, often containing humidity, can mix with your gasoline. While the gasoline won’t freeze until 97-degrees below zero, the water mixed with the air in the gasoline will freeze at 32-degrees Fahrenheit.  Therefore, when you have less gasoline in the tank, and more moisture-rich air, you are a greater risk of having frozen liquids interfere with the gasoline’s ability to flow.

You don’t merely need to worry about the gasoline in your tank – you also have to worry about it in your fuel lines. This is particularly true where moisturized air has already infiltrated into your gasoline. One way to avoid this problem is to periodically use a gasoline additive that dries the gasoline (removes the moisture) and helps to prevent the gasoline from freezing.

Some of these products claim to help clean your fuel injectors, improve winter starts and improve your mileage. Those benefits are nice, if true, but if all the additive does is to keep your fuel lines dry, it’s well worth the effort. Manufacturers may recommend adding a bottle of their additive with every fill up. That, however, can prove expensive. Every two or three tank full is probably enough.

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...

Get out to McHenry Music Festival for a good time and music near to home

Some folks here in McHenry will load up the car and head out to Red Rock Amphitheater near Denver to see a show. Some will go to the MSG Sphere near Las Vegas. Some will go to the Bonaroo Festival Concert to see a show. That’s quite a bit of driving and you’d better make sure your vehicle is up to the trip. What happens, however, if something goes wrong – if your vehicle breaks down while driving there or back? What happens if the show is canceled, as happened this year with the Bonaroo Festival? We’re talking about some serious inconvenience, aren’t we? Wherever you go, whether your driving to Colorado, Nevada, Tennessee or anywhere else in this continent, you want to perform your due diligence and make sure the vehicle is up for the trip before you go. And it doesn’t really matter if you’re driving somewhere to see some live music or for any other purpose. A breakdown can be costly and may put you at the mercy of weather conditions or nefarious characters that come across you while y...
