Movies can do almost anything using computer-generated imagery these days. So why even bother with practical effects, right?

No way.

Computer graphics are great, but they can never truly fool an audience. Everything feels just a little bit fake. For an authentic, immersive experience you can get lost in, practical effects and stunts are necessary.

No one understands that more than the creators of Mission Impossible 5: Rogue Nation.

The driving stunts were not only all real, but performed by the actors, rather than stunt drivers.

You know it's important to visit your local service center for an oil change at regular intervals. What makes clean oil so vital to the operation of your car? Is it okay to skip oil and filter changes sometimes?

This blow-by-blow of how oil works shows off the extent of oil's value to your vehicle's engine.

Oil starts off in the sump-- or the "oil pan." It gets sucked up via a pickup tube, where it is pressurized, and begins its journey through every part of the engine.

First it is run through your oil filter, to…

When Bear Grylls isn't running around the wilderness surviving off of insects and throwing himself headlong into danger for sensationalistic stories, he's throwing himself into danger for safety education.

What would you do if you were driving down a hill, when suddenly your brakes fail?

You have to do several things. Take your foot off the accelerator and pump the brakes. Turn on your emergency flashers. Downshift to a lower gear. Apply gentle pressure to the handbrake to slow down without skidding.

If possible, pull off the road if there is a soft bank, or an uphill slope…

If you really thought cars had faces, then our entire used inventory would look like a bunch of creepily staring ever-open eyes, gazing at you motionlessly. It would be like a horror movie-- or maybe we're just pre-emptively excited for Halloween now that it's September.

Actually, it turns out you do see faces in cars, even if you didn't realize it.

A study hooked a bunch of participants up to an FMRI machine, and showed them pictures of cars. Everyone in the study showed activity in their Fusiform Face Area-- the part of the brain used to…

The number of miles you should travel between oil changes depends on several factors. Certain cars, or model years may be more efficient with oil than others. The type of oil you use also plays a big part, especially when you compare regular oil to high-performance synthetics.

However, there is another factor you may not have considered: you.

Fit one of these extreme driver profiles? If so, you might want to change your oil more often. http://t.co/yB03TPqzMV pic.twitter.com/rkufuLc0fp

There's nothing that complements a luxurious BMW like a coat of dirt, said no one ever. But could a little grime add to your gas mileage?

It all started in 2002. Tom Wagner Jr, and engineer, wrote an article proclaiming that his car got better fuel economy after a wash. The controversy sparked.

Counter-intuitively, many claimed that dirt particles on a car acted like the divots on a golf ball, which help reduce wind resistance as they sail through the air.

The Mythbusters ran a very careful analysis, tracking the precise amount of fuel consumed by a vehicle when…

Look at our collection of Volkswagen Beetles. They are distinctive, attractive, and nimble. Well-engineered. Reliable. We're proud of them. But they aren't quite the sportiest of our Volkswagen inventory. Ask your average Joe if he'd enter a Beetle in a race, and he'd probably look at you like you had two heads. But that's exactly what Volkswagen, in partnership with Andretti Autosport, is doing. The GRC Beetle is no ordinary bug, however. It starts with Volkswagen's baseline of reliability a
