Good History Book
Format: Kindle
Twenty years that change history and the Americas. Even though the civil war ended slavery at a humongous cost, it it failed to bring social justice a d civil rights to the population of the country. It was not until 1920 that women were granted voting rights. And some problems and divisions persist nowdays.

interesting and fresh perspective on the American civil war
Format: Kindle
Fresh perspective on the well known American Civil War. I appreciate Dr Taylor’s emphasis on the preservation of slavery over the states’ rights argument for why the American Civil War was fought.

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.
