Dear Lifehacker,actually benefit—I've heard some people say it doesn't actually matter. Is it really worth the cost, or are they just recommending premium to get me to spend more? Sincerely, Photo by TaxBrackets.orgon Flickr. Dear Confounded, I don't blame you for your confusion, what with all the gasoline-based advertising and vague "recommendations" out there. You may, in fact, be well able to ditch premium gas; unfortunately, the answer is a bit more complicated than a simple yes or no. So, we'll start by explaining how your engine works—without getting too technical—and what kind of gas is right for your particular vehicle. Advertisement What Premium Gas Does Premium gas, which usually has an octane level of 92 or 93 (compared with regular's octane level of 87), is designed to prevent knock on cars with high compression ratios. The compression ratio is the total volume inside the cylinder that is displaced when the piston moves. If you use low-octane gas on a … [Read more...] about Should I Use Premium Gas in My Car?

Why spend more at the gas pump when you can easily spend less? The team at The Family Handyman shares this list of DIY tricks for a noticeable difference in your fuel costs. The savings are based on driving 20,000 miles per year, in a car that gets 20 mpg, with gasoline priced at $3.75 a gallon. Save $900 by Keeping Your Tires at the Right Pressure Surveys show that 60 percent of the vehicles on the road have tires that are underinflated by at least 30 percent. That's at least 9 psi below the manufacturer's recommended pressure. That can cost you almost 7 percent in wasted fuel ($245 per year, or 24¢ per gallon). Plus, low air pressure causes premature tire wear, and that can cost almost $300 over the life of the tires. For best results, check your tire's air pressure with a digital pressure gauge (about $10 at any auto parts store) and fill to the recommended pressure shown on the decal inside the driver's door or on the driver's door pillar.

Sport photography isn’t shot from the sidelines anymore, it’s made by athletes as they do their thing. But before they can do that, they have to learn to shoot like a pro. We went inside the camp where they’re trained. The GoPro athlete camp I attended was geared specifically towards the company’s adventure athletes: rock climbers, kayakers, stand-up paddleboarders (SUP), human flight, and a free runner. Advertisement Though opportunities for adventure at the camp were never in short supply, participating in the activities was only part of the fun. What the five day program really focused on was instruction on content creation, and all of the skills that go into it. Banff provided the athletes with diverse, stunning environments where they could do their thing while capturing every epic moment — and GoPro’s training, product development, and media production teams ensured that each athlete was learning the tools and knowledge to create the best … [Read more...] about How GoPro Is Turning Its Athletes Into Storytellers
In the caterpillar-versus-plant fight, the winner might seem obvious. One side sits motionless in the sun, while the other feasts on it. But the tomato plant has a nefarious defense strategy. In some encounters with herbivores, it winds up relatively unscathed, while the caterpillars wind up eating each other. Researchers have long known that plants have myriad ways to protect themselves from predators, but a newly-discovered method ranks among the most disturbing: somehow, tomato plants seem to be pushing hungry insects to cannibalism. This finding could have important implications for agriculture—after all, if the insects are eating each other, they’re not eating the plants. Advertisement “It’s a novel way that plant defenses alter the choices that animals make,” study author John Orrock, associate professor at the University of Wisconsin-Madison told Gizmodo. “The consequences seem to benefit plants. They change their chemistry to be less … [Read more...] about Plants Turn Caterpillars Into Cannibals to Save Themselves
One thing you’ll learn from the newest installment of DC’s weird, junk-food specialty project: Harland Sanders is like a Kentucky Fried Christ who died and came back to life to spread the gospel of finger-lickin’ poultry parts. The letter column says so. Advertisement KFC: The Colonel Corps follows up on last year’s bizarre story that introduced dead restaurateur/corporate mascot Colonel Harlan Sanders as a super-ornery character in the DC Universe. It opens with the Colonel having a dizzy spell and then getting a visit from an alternate-reality version of himself: Colonel Sunder, the finger-lickin’ fiend who got his guess-what-chicken-butt kicked last year, is messing with the minds of Sanderseseses all over the multiverse, stealing crucial secret-recipe knowledge from their white-haired noggins. Sanders-Prime and his distaff analogue decide to use a Flash and a cosmic treadmill to traipse through time and space, gather allies and find out … [Read more...] about DC’s New KFC Comic Turns Colonel Sanders Into Fried Chicken Jesus
