Definitely buying again.
Style: High Mileage 150K, Size: 5 qt (Pack of 1), Configuration: 5W-20
In MY experience, this has been fantastic, spouses car is a 200k+ mileage Kia shortage, which I mean, it’s always burned oil, even the manual said normal operation can burn 1qt per 1,000 miles. Either way, i was adding oil a lot. At least 2 quarts a month or more. After running this oil, I have only added 1.5 quarts in over 2 months. Results obviously not typical, but in my experience, this stuff works. I also use the restore and protect Valvoline on my car, with great results. Scoped it after a few full oil changes and engine looks clean. Great value for what it potentially will do.
