Archoil AR9100 Friction Modifier

The absolute best product on the market

I actually bought this for a 94 f150 with a 302 . It had been in storage for 18 years . Despite the the low mileage of 53000 it used a quart of oil every 500 miles . I assume the oil rings were stuck from sitting . After driving it and giving it regular oil changes it improved to a quart every 1000 miles . It now has 160000 miles on it and I decided to try arch oil in it to see if it would free the rings . I used 8 ounces to 6 quarts of oil . After driving a wile the oil was black as coal and I drove 2000 miles without adding any oil . At 5000 when it was ready for an oil change it was only a little low . I was impressed. I changed it and it no longer uses oil plus it has way more power . The best part is I get 50 more miles per tank . I will continue to use it and I recommend it to anyone. Thanks for making a great product.

After receiving, which turned out to be neglected, 7.3 power stroke with 240,000 miles. Using friction modifier and fuel treatment for the past few thousand miles, the engine runs smoother and quieter. Fuel mileage may have went up a bit also.

Use the Archoil in a lot of my motors. Very pleased with the results.

I noticed right away after an oil change with Archoil added, that my truck ran smoother and had less smoke at start up. I will definitely be using this every oil change from now on.
