Hot Shot’s Secret

2006 Dodge Ram 1500 with 113,000 miles. I change the oil a week ago and noticed the usual pick up in performance and acceleration as you do with any oil change. A week after I changed the oil I added 8 ounces of our FR3 and noticed even more acceleration, smoother idle and engine was just overall more quiet. Every time I drive the truck now I notice the difference. So far so good!

I use this product every oil change to increase the life of my engine.  It provides me no power or fuel economy gains, but the future of my engine is equally important.

I've recently started using FR3 in my diesel pickup. So far, my used oil analysis metal numbers (Fe and Al) improved a bit over using my regular untreated oil. Hoping that trend continues.

Used with fresh oil change before 1300 mile trip, went from a 17.3 average mpg to 24.4 average mpg double checked it with math at every fuel stop and computer  was spot on every time..

So far I have notice smoother idle and better cold starts  Mpg I can not verify, but has certainly  Worked great in the power steering !

Real deal

I've only used this product in my rear differential but if it works in the other fluids like it does in the differential oil, superb results!

Got it in my oil and even in the oil or my race car. Also going to put it in the front and rear diffs when I get around to servicing those

Fanstastic value for money and quality. I have litrelly added the FR3 to all applicable fluid. The FR3 has paid itself in the improved MPG

Honestly, I didn't notice any difference. Really don't see how i would have. I used it in my 71 Chevelle SS 454 4 speed car. Ran good as it always has. Was great before I put it in and its great now. I will use it again on next oil change. The science says it works so I will go with it.

Honestly
