Archoil AR9100 Friction Modifier

2006 6.0 was starting rough after the full engine rebuild, I did reuse my factory Ford injectors since they were operating normally before the year down. Started using fuel additive from archoil to see if that would loosen them up but no luck, changed the oil and added Archoil friction modifier and she starts perfectly now.

Before Archoil AR9100 the engine had a knocking sound but it has disappeared. She sounds great now. Can’t wait to use the fuel additive!

Since I have been using this product the ole 7.3 has been purring like a kitten and I just might be able to pass on to my grandson.

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.
