Slick 50 ReCharged High Mileage Engine Treatment Automotive Additive, 10W-30 Motor Oil, 32 Ounce

I've been using Slick 50 products for years and will continue. My 2001 Ford Explorer Sport has over 140,000 and still going strong. This keeps the engine wear way down and I do a lot of highway miles. The same with a 97 Prism I had before this one, over 130,000, lots of city and highway mileage over the years. After every oil change I've used this and have even extended the time in between changes when I just couldn't get around to it. Walmart delivery was great and the price was right. Inspections are a breeze so with this one, spare yourself lots of problems and pay for a better product.

I've used Slick 50 Engine Treatment in my vehicle since I bought my 2002 Jeep Grand Cherokee brand new 12 years ago. I pour a bottle in the crank case after every oil change, and that's always with 100% synthetic oil. I used to buy it at pep boys. But, I found out wal-mart sells it cheaper than anyone else around. So, I've been buying it there for the last 3 years. 195,000+ miles later, my engine is still as strong as ever, and it has passed smog tests every time when inspected!
