I started using Hy-Per Lube products when I lived in Seattle. A mechanic there I knew recommended it for my then old Volvo once it had over 100,000 miles. My sister drives that Volvo which now has over 200,000 miles on it and she still put Hy-Per Lube Oil Supplement in it. It worked great in that car an works well in my Ford Escape that has almost 200,000 miles. Still has plenty of pep for driving in the mountains here in Colorado and doesn't burn a drop of oil.
