Always pleased with these two products. A must have for my power stroke. Would love it if archoil could throw in a window sticker with my next order !
I have been using the friction modifier treatment on my 2004 Yukon for the last three years to stop typical piston slap and valve train noise on cold startup and it took about 300 miles on the first application to stop these issues. I have since added about 1.5 ounces of friction modifier per quart of oil at each oil change ever since. At 156,000 miles there are no scary engine noises on cold startups. I figure this product will give me many more miles on a good old truck. I added the fuel treatment after using the oil treatment and am very happy the way this truck runs with it. Much better than regular gas without it.
Just started using the friction modifier and fuel treatment. I notice my truck running better the first 100 miles.
Order was delivered very timely. I added the friction modifier to the oil in my 7.3 as well as fuel cleaner and fuel treatment. After two miles there was a considerable decrease of engine noise and the truck has ran smoother ever since.
Best product ever!!
