Description:
An all-in-one encyclopedia that explains the technology of everyday life
Get inside the machinery of the modern world and understand the science that makes it all work.
Have you ever been tempted to take the back off your TV? Have you wondered about what's going on beneath your feet on the street where you live? How Technology Works lifts the lid on the technology you use all the time but take for granted. It also takes you to places you'll never get the chance to see, such as the inside of a nuclear storage facility or the crew capsule on top of a Moon rocket. The book takes you on a journey of discovery, starting with technology at work inside the human body before exploring cities and factories and then blasting off into space. Along the way, you'll lose yourself in super-detailed illustrations that reveal amazing hidden things and explain how they work.
How Technology Works is an inspiring guide that makes technology fun, fascinating, and accessible for curious minds of all ages.

Top-tier engine protection that runs quiet and smooth
Size: 5 Quarts
I’ve used Castrol EDGE in a couple of our vehicles and always come back to it for consistent performance. It extends the time between oil changes and holds up well under both daily driving and highway mileage. We don't "extend the time" though. It's changed, on the dot, every time. The consistency and quality of the oil's condition at change, though, is easily able to be seen that it would go for much longer.
Engine runs quieter, and I’ve noticed better fuel efficiency over time compared to conventional oil. Whether that's how attentively I drive and watch the mileage meter on the dash or the oil - is up for debate ;)
It doesn’t burn off as quickly either, which is great if you’re keeping an eye on long-term engine health.
The bottle design pours cleanly with a smart spout, which saves unnecessary messes in the garage.
Pros:
Strong wear protection and long-lasting
Improves engine quietness
Easy-pour design
Tip:
Use it with a high-quality oil filter for maximum benefit don’t skimp on either part and you'll be golden.

Excellent choice for long oil change intervals.
Size: 1 Quart, Pack of 6
I'm a former dealership mechanic and for years I used whatever we had in the bulk tank which was usually Valvoline conventional. My last job was at a German car dealership. Castrol was the oil recommended by the German manufacturers and that's when I started using Castrol. In my experience Castrol is an excellent oil. My 2014 Ford just rolled over 242,000 miles and even with factory 10,000 mile oil change intervals, from what I can see through the oil fill the top end of the engine is still clean. I've never had to remove the valve cover. It's using about a quart between oil 10,000 mile oil changes which is great because when it was new it used about a 1/2 quart between changes.
