When To Say No To Riding

When To Say No To Riding Six clues to judge when it’s best to not ride America is a big, sprawling place, vast enough that no one can cover all of it in a lifetime. It is easy to be thirsty, to want to ride every inch from the blue stone shores of Maine to the wide expanses of Nevada. But sometimes it’s best to leave those miles unridden. Everyone has different thresholds for when it’s too hot, too cold, or too wet to ride. The same goes for state of mind, your health, and your level of conditioning. When do these variables form enough of a distraction to merit leaving the bike in the garage? When does exposure to riding conditions make the risk greater than the reward? Here’s where we might draw the line. Nasty Weather Riding in rain is no big deal if you slow down and are adequately prepared. A forecast of torrential downpours or gale-force winds, however, should have you rethinking your ride or reaching for the car keys. Extreme Heat Temperatures reaching triple digits can lead to hyperthermia, especially if your skin is exposed to the sun and hot wind. Vented gear and a hydration pack can help, but there’s no shame in bagging a ride until the evening when temps have become more manageable. Chill Factor Riding in 50 degrees Fahrenheit doesn’t sound too bad, but there’s a reason cold comes at you so hard on a bike: windchill. Add 65 mph of hair-waving breeze through your gear and exposed parts of you will feel like they’re riding through 39-degree weather.

Letting a car idle requires more time for the vehicle to warm up and allows excess fuel to get into the engine, which isn' t good for wear and tear. Turns out, the answer doesn' t lie in frequency. Experts at AAA, a federation of motor clubs, say it 's not a good idea to warm your car up to keep it from freezing.

Letting a car idle requires more time for the vehicle to warm up and allows excess fuel to get into the engine, which “isn’ t good for wear and tear However, if temperatures go lower, car owners should have a higher concentration of antifreeze, up to 70 percent. If a driver isn’ t sure what the antifreeze

With frigid temperatures sweeping the country, many car owners are asking: How often should I start my car to warm it up?

Turns out, the answer doesn't lie in frequency, says Mike Calkins, manager of technical services at AAA.

"It's probably not a very good strategy" to repeatedly start up your car, "warming it up to keep it from freezing," he says.

If a driver were to start their engine in extremely cold weather, Calkins says they would need to get it up to full operating temperature, which is best accomplished through driving the car around. Letting a car idle requires more time for the vehicle to warm up and allows excess fuel to get into the engine, which "isn't good for wear and tear," according to Calkins.

Warming Up Your Car in the Cold Just Harms the Engine

Warming Up Your Car in the Cold Just Harms the Engine The long-held notion that you should let your car idle in the cold is only true for carbureted engines. In the thick of winter, the common wisdom is that when you are gearing up to take your truck out in the cold and snow, you should step outside, start up your engine, and let it idle to warm up. But contrary to popular belief, this does not prolong the life of your engine; in fact, it decreases it by stripping oil away from the engine's cylinders and pistons. In a nutshell, an internal combustion engine works by using pistons to compress a mixture of air and vaporized fuel within a cylinder.

The long-held notion that you should let your car idle in the cold is only true for carbureted Should You Warm Up Your Car When It 's Cold ? We asked Volvo, which conducts cold - weather testing in the Arctic, whether their new cars need any sort of warmup, and the answer was an ever-so-slightly

However, even after some driving, it only takes a couple of hours for the engine to cool down from full operating temperature, Calkins says. Moreover, he says that repeatedly starting a car without running it long enough to recharge the battery can lower the battery's capacity over time.

Instead of starting up cars often, Calkins believes that vehicle owners should focus on adequate antifreeze protection.

According to Calkins, antifreeze "prevents the coolant mixture from freezing." When water or any liquid freezes, it expands, which Calklins says can create pressure that can crack engine blocks and cause damage in the car.

Calkins says that cars typically use a 50-50 mix of antifreeze and water, which provides protection for -30 to -35 degree Fahrenheit weather. However, with temperatures lower than that during the polar vortex, car owners should have a higher concentration of antifreeze, up to 70 percent.

How Severe Cold Affects Your Car (and What to Do about It)

How Severe Cold Affects Your Car (and What to Do about It) We talked with a repairman from Alaska to find out how the cold can affect cars and hear about any possible solutions. Problem: Deflated tires As the air in your tires gets colder, it contracts and has less pressure. Tires correspondingly become underinflated. Solution: Check your tire pressure more often than you normally would. The Car Care Council recommends doing so once a week. You might think a little deflation provides better traction, but tire experts caution against running tires below manufacturers’ recommended pressure, as that can cause uneven or unsafe tread wear.

it should be “ how often should i start my car so the battery doesn' t die” or “ how long should i let my car idle to get it warm enough to drive “. for the first one, you should start your car atleast once to prevent the battery from discharging and drive it around for 10–15 minutes before switching it off

Let it idle for a minimum of five minutes before you take off. Get that oil splashing around in there. I agree that this is accurate, and I also think it ’s still a bad idea, and you should let the car idle for at Nobody will ever love you because your drive right off in cold weather . Take moment and let the car

If a driver isn't sure what the antifreeze protection level is in their car, Calkins recommends they find out soon to protect against possible damage.
