By Tom Barlow, dealnews contributor Sure, the weather may be pleasant today, but looming all too soon for most of us are snow, sleet, ice, and the deep freeze of winter. You could wait until some frigid morning in December to find that your locks are frozen, your windshield wipers only smear the snow/mud mix, or you're stuck changing a flat in your church clothes in the dark on an ice-covered berm. Why not take care of some preparations now, while the weather is still pleasant? We've got some deals on the products you need, to make it even easier. Step 1: Prepare Your Car Change Your Oil Oil varies in viscosity, or flow property. Thick oil flows like sludge, thin oil moves like maple syrup. The "10W30" on an oil refers to the flow rate; the lower the number, the thinner the oil. In winter, low temperatures lower the flow rate of oil, so you might consider using a less viscous oil, such as 5W30 — such as a quart of this Quaker State Advanced Durability 5W-30 Motor Oil ($3.49 with in-store pick-up, a low by $1) — if you anticipate very cold weather. Moreover, Goodyear Auto Service locations are currently offering a Standard Oil Change ($19.98), if you're afraid to do it yourself. (Note that winter-optimized oils may cost extra.) Flush and Fill Your Radiator Radiator fluid degrades over time, and in winter the mixture should contain at least 50% radiator fluid, which should keep your coolant moving down to -34 degrees Fahrenheit. An inexpensive device called a coolant tester, like the Peak Antifreeze and Coolant Tester ($2.98 with free in-store pickup, a low by $5), can get the job done. Now is also a good time to inspect hoses for leaks and replace them as needed. Fill Your Windshield Wiper Reservoir Not all windshield wiper fluid is formulated with enough non-freezing ingredients to keep it flowing in cold weather, so check the label to make sure your solution is made for winter conditions. Try picking up a 1-gallon bottle of Prestone De-Icer Windshield Washer Fluid (search for "AS250" to find it) and get a second bottle free after this mail-in rebate ($3.99 with in-store pickup, a savings of $4). Buy Snow Tires If you're destined to deal with heavy snowfall, invest in a set of snow tires. All-season tires, which are also popular, are a compromise between high-mileage tires for summer and snow-gripping tread for winter. A winter tire, on the other hand, is made specifically for traveling in the snow, with more aggressive tread patterns and a softer compound that won't get hard and glassy in cold weather. Swap out these tires in the autumn and save up to $80 via mail-in rebate on a set of four new winter / snow tires through various offers at TireRack. It's also important to keep an eye on your tire pressure when the weather is foul. An overinflated tire won't grip as well, and an underinflated tire dangerously compromises a car's handling. Consider Winter Wiper Blades If you deal with a lot of snow and icy road spray, you may want to upgrade to winter wiper blades, which have a rubber coating that keeps ice from building up on top. The Car Talk Radio guys warn though that it's a bad idea to keep winter wiper blades on year-round because they are heavier and could prematurely wear out the motor on your wipers. Recently, we found this $5 mail-in rebate for ANCO Winter Wiper Blades. Check Your Battery Batteries run by a chemical process, and that process is slowed when the temperature plummets. Have your car shop check your battery to make sure it's putting out enough juice. If not, now's a good time to replace it. Top Off the Water in Each Cell If your car battery isn't a sealed battery, check the water level in each compartment while you're at it. Also examine the cables, especially where they attach to the poles of your batteries — they should be firm and free of corrosion. If not, tighten the connection and use a wire brush to remove the corrosion. Step 2: Stock Up on Supplies A little advance planning can minimize the dangers of winter driving. Part of this is stocking up on the right equipment to deal with breakdowns. Lock De-Icer A spray can of glycerine can help thaw those pesky frozen locks that occur when melting ice trickles in. You can pick up a de-icer at your local auto parts or big box store. If it's already too cold to make the trip to a brick-and-mortar store, try the Bell Automotive V500 Lock De-Icer and Lubricant ($1.37, with $3.04 s&h, a low by $3). Blanket or Tarp Cotton blankets lose heat when wet, so opt for a synthetic or wool blend blanket. A plastic tarp to kneel on while changing a tire might also come in handy. Boots and Gloves Get a good grip on the situation with solid boots and work gloves. But again, not cotton gloves. A good work glove is the Dewalt All Purpose Synthetic Work Glove ($10.38 with free shipping via Prime, a low by $6), made from a combination of leather and spandex. It also features a Velcro closure. Ice Scraper Make sure your ice scraper is long enough to reach the middle of the windshield and sturdy enough knock snow off the roof. This Hopkins Duo-Grip 22" Scraper ($3.97 in-store, a low by $6) has a sizable reach and 4" scraping edge. For a shipped option, try the the Hopkins 22" Snow Brush ($3.11 plus $4.41 s&h, a low by $3). Small Shovel Every once in a while there's situation where you'll need to shovel yourself out of a snow bank. A small utility shovel like the AAA Aluminum Sport Utility Shovel ($18.30 with free shipping via Prime, a low by $7) is just the ticket. Flashlight Pack some spare batteries for a flashlight that's bright enough in case you have to change a flat tire in the dark. Check dealnews for bargain flashlights, like the Zoom Fisheye Lens Cree Flashlight ($9.99 with free shipping, a low by $6), as they appear regularly. Jumper Cables On the coldest of mornings, even reliable car batteries can fail, and if you want to get going, you'll need a jump from someone. Finding that someone is much easier if you have your own jumper cables. Keep the Hopkins Juice Performance 12-Foot Standard Power 10-Gauge Booster Cable ($16.95 with free shipping, a low by $6) on hand for just such a scenario. Tire Chains In the deepest snows, tire chains — which fit around your tires providing additional grip — are especially useful. Tire chains come in a variety of sizes to fit different vehicles and wheels. They can get pricey if you're buying for all four wheels, but Amazon has a variety of discounted tire chains that are at least 50% off. Bag of Abrasive Materials Sand or salt tossed under your wheels could help give you the traction to get unstuck. Even a little Feline Pine Original Cat Litter ($10.62 with free shipping via Subscribe & Save, a low by $9) can help get you moving. If your car has rear-wheel drive car, carrying this weight over the rear axle could help the car's handling, too. A few minutes of preparation today can save you from grueling hours of frustration when the snow begins to fly. If the weather to come is as harshly cold as the summer was hot, you'll appreciate the forethought.
