Bestline Premium Synthetic Engine Treatment - 2 Pack

Before using Bestline Engine Treatment, I drove my car across town on the expressway withthe air condition on. When I got home, The radiator bubbled and bubbled because the carhad over heated. It had a new radiator. Each time I drove the car in the daytime, it wouldn'tstop running when I turned it off, dieseling. Yesterday I had to drive down town and acrosstown and all around town. No dieseling, ran smoother, and no over heating, and it hadmany chances to do all that.

This is the first additive I’ve ever had success with! The noisy lifters just clattered away after trying multiple additives, using them as directed. One use of the BESTLINE fixed them. I changed my oil and added BESTLINE. After 200 miles the noise stopped completely. I recommend adding it to every oil change if it’s in your budget.

Heard and saw several reviews regarding BestLine Synthetic products. Thought I'd try it out in my 2011 Ford. I had lifter knock. Took the truck to the my local Ford dealer and they stated it was the number one additive on the market and technician recommended it as well. Immediately after my vehicle was serviced the technicians and I were surprised how quite the engine was running and the knocking was GONE! I have seen an increase in fuel mileage and power. Highly recommend this product to anyone. I'm adding to all our vehicles as we change engine oil, not to mention in my tractors.

I use this religiously in my classic 1980 British sports car. It runs noticeably cooler, smoother and quieter with BestLIne. I will not run the car without it.

Use this in all my vehicles including the diesel formula in my farm tractor

Quieted engine right down

My cars sound quieter and MPGs went up

So far so good
