Incredible motor oil !
Style: Restore & Protect, Size: 5 QT, Configuration: 5W-30
I've used this in my 2014 Buick Encore with 91k miles on it for 2 oil changes and the results are extremely impressive. The engine in the 'ole gal is noticably quieter and my gas milage is definately improving. I switched from Mobil 1 to this oil based primarily on reviews and I'm glad I made the switch. This vehicle is not only my commuter car (80 miles per day), but it's my "winter" vehicle so it sees some temperature extremes. This oil is remarkable ! Time will tell, but I definately recommend it.

Good! I would buy this again if needed.
Style: Restore & Protect, Size: 5 QT, Configuration: 5W-30
Good! I would buy this again if needed. The best oil to use in a KIA, IMO. Keeps it clean and might help prevent oil burning. Your KIA needs the best oil you can feed it. They are known for failing engines so why not give it the best, especially if its out of warranty like mine!

USE THIS 3 yr old-10yr old cars But it is not for use for classic muscle car-flat tappet cams
Style: Restore & Protect, Size: 5 QT, Configuration: 5W-30
Valvoline has come up with a tested, amazinng engine oil for not the newest cars..but for cars say 3-10 years old that may have some varnish-sludge build up..works slowly enough over time so it doesnt suddently clog the filter, but DO change oil and filter at 3500, not more. In fact 3500 to 4K max for ANY car, any time. DO NOT go longer as some mfg or oil say you can. Tests show that sludge builds up. This oil is NOT for classic muscle cars with flat tappet cams.

Amazing Oil!
Style: Restore & Protect, Size: 5 QT, Configuration: 5W-30
So far after first oil change it made my Toyota Tundra 5.7L with 255k miles run smoother and quieted the timing chain tensioner knock that I was quoted $5k and up to repair! Will be using from now on to 500k miles plus!

A fascinating glimpse into the undoing of the Confederacy
Format: Paperback
This dense and and well-written book includes some really interesting insights into how the Confederacy was formed, but then ultimately challenged and destroyed by some of the people it excluded. In Confederate Reckoning, we get to learn about the epic political battle in which White women and slaves in the South helped to undermine the Confederacy and determine the outcome of the Civil War.
