Do Jet Engines Need Oil Changes?

1 week ago | slashgear.com | Zohaib Ahmed

Every few thousand miles, we pull into a shop, wait our turn, and let a technician drain and replace the golden liquid that keeps our cars running. Jet engines, however, operate on a completely different playbook. Despite being far more complex, most commercial jet engines can go their entire service lives without ever needing a scheduled oil change. That doesn't mean they don't rely on oil — they do, but the way they use it is fundamentally different.
Is A Honda Clarity Worth Buying Today? Here's What Owners Have To Say

1 week ago | slashgear.com | Zohaib Ahmed

Though the hydrogen and hybrid Clarity models were officially discontinued in August 2021, the lineup remains one of Honda's most ambitious stabs at alternative fuel innovation. Launched originally in 2008 as the FCX Clarity, and later reborn in plug-in hybrid, electric, and hydrogen fuel cell variants, the Clarity was always ahead of its time. Sadly, being ahead doesn't always pay off in a world where hydrogen refueling stations are still few and far between.

1 week ago | slashgear.com | Zohaib Ahmed

Diesel Exhaust Fluid (DEF) is a crucial component in modern diesel vehicles, introduced to comply with US Environmental Protection Agency (EPA) regulations that began in 2010. It's a solution made up of 32.5% urea and 67.5% deionized water, used to reduce harmful nitrogen oxide (NOx) emissions. The fluid is injected into the exhaust system through Selective Catalytic Reduction (SCR), where it helps break down NOx into harmless nitrogen and water.

The commercial airliner market is like any other, where some products like the Boeing 727 see massive success, while others struggle to find their wings. The Airbus A330-800neo definitely falls into the latter category. It was launched back in 2014 as part of Airbus' efforts to replace the aging A330-200 and compete with Boeing's ever-popular 787 Dreamliner.
Why The F-22 Raptor Has Never Had A Confirmed Kill In Active Combat

The F-22 Raptor was built to be the pinnacle of air combat dominance. The goal was to launch a next-generation replacement for its aging fleet of F-15 Eagles and F-16 Fighting Falcons, counter advanced Soviet threats, and secure American air superiority. Lockheed Martin's design won out. After its first flight in 1997, the Raptor entered service in December 2005.
How To Tell If Your Truck Has A CP4 Fuel Pump

1 week ago | slashgear.com | Zohaib Ahmed

If you browse forums often, chances are you've come across some heated discussions around the CP4 fuel pump. The CP4, short for "Common Rail Pump 4," is a high-pressure fuel injection pump that made its way into Ford and GM diesel trucks starting in 2011. It was intended as a next-gen replacement for the tried-and-true CP3 pump, which had built a reputation for rock-solid reliability. Unfortunately, it didn't quite follow in its predecessor's footsteps.
How Often Do Semi-Truck Engines Need Their Oil Changed?

2 weeks ago | slashgear.com | Zohaib Ahmed

Keeping up with oil changes is one of the simplest yet most crucial ways to extend your truck's life. Diesel engines, especially in hard-working semi-trucks, deal with massive loads and long hauls, so oil that's clean and in good condition isn't optional, it's essential. While your average consumer vehicle typically needs an oil change every 5,000 miles or so, commercial trucks have a different schedule. Semi-trucks typically have oil change intervals that stretch to around 25,000 miles.
What Actually Happened With Mazda's Once-Ambitious Luxury Division?

2 weeks ago | slashgear.com | Zohaib Ahmed

By the early 1990s, Mazda had already carved out a niche for itself with hits like the nimble MX-5 Miata and rotary-powered RX models. But behind the scenes, it had bigger ambitions — ones that involved rubbing shoulders with the likes of Lexus and BMW. Coming off the back of Japan's economic high in the late '80s, it didn't seem like such a stretch either. Japan's currency had strengthened, businesses were booming, and auto manufacturers were flush with cash and confidence.
Why Do ATVs Have A Thumb Throttle?

2 weeks ago | slashgear.com | Zohaib Ahmed

You've probably met the thumb throttle if you've ever hopped on an ATV and reached for the gas. It's that little lever tucked under the right side of your handlebar, and it's rather simple to use. You just push it with your thumb and off you go. The mechanism resembles a controller's trigger and differs from the other option, twist throttles, where you roll the whole grip to accelerate.
What Is A Conversion Package On An SUV?

You don't always have to drive a brawny pickup truck to tap into the world of utility and off-grid capability. These days, dependable SUVs with unmatched reliability — already a popular vehicle type across North America — are stepping confidently into that space. Traditionally, pickups have held the monopoly on rugged, utilitarian features.
