Hot Shot's Secret FR3 Friction Reducer Nano-Lubricant with Wear Protection, 32 oz

I'm a former auto mechanic from the days before computers ruled the automobile, so I mainly do not use oil additives. However, my LS2 has had more noticeable lifter chatter over the last couple years. I tried Seafoam in the crankcase as directed, drove it 100 miles and changed the oil. It made zero difference. After researching loud lifter knock for my other car (2006 300 C), I stumbled across this product but also Stiction Eliminator (bought that too). I drained 20oz of oil from my LS2 and then added 20oz of FR3. I didn't have to put on more than 20 miles before I took note of how quite the lifter chatter is, full honesty. I gained roughly 5lbs of oil pressure when data logging and the engine is much more responsive. Directions state to change the oil first but since I'm real close to changing it again (with AMS Oil), I feel it's worth more to run it the current oil and then flush everything out for a fresh change. For the 300 C (5.7 Hemispherical), the knock was loud, had it at a reputable engine shop and they said it needs a new engine, for the low low price of $8,700). Had it towed back home and it sat for 3 weeks. Added Friction Eliminator to the oil and ran it for 20 minutes. The noise is almost completely gone now. I definitely recommend both products!

It works for power steering pumps too, mine went from making noise at idle, to now I can barely hear it worth the money I paid for sure, it's used for motor oil and power steering fluid, very compatible to different applications, so far it's working as should ,durability so far is absolutely great, and no leaks, helps with that too compatibility between both diesel and gas engines, very useful.

This made a noticable differnce in my '93 Cummins. The engine runs smoother and sounds a little less clattery compared to whatever oil the previous owner had in it. I've been using it since the first oil change I did after I got the truck, so I can't comment on whether or not it increases fuel economy, but I use 18oz of FR3 every oil change and 2-3 oz of EDT every fill-up, and my truck gets 19-22 MPG consistently. '93 Dodge D250 Club Cab Cummins/Auto 3.54 gears. Stock size all-terrains, FFS Leveling kit & a 2" block in the back. I'd say that's pretty respectable for a 31 year old 3/4 ton truck. The oil is still honey colored on the dip stick when I change it every 5,000 miles.

Great products!

Awesome full recommended

Both of my car and truck seam to run smoothly and better gas mileage. Took a few times driving them to notice the difference. I am satisfied.

I use this all the time I noticed my diesel engine sounds quieter and smoother running and seems to have a bit more pep and I put this in 2 older diesel trucks and noticed the same thing from both .I use all other hot shots products this one and especially the fuel additives

Great stuff. Used for 10 years in all equipment.

I did an oil change in my truck about a week ago, my drive is 130KM a day. I didn't really notice any fuel savings until the end of the week. My truck usually consumes 13.8-14.2Liters per 100 KM, now its stayed consistent @12.5L Per 100KM. SO imagine it should get better fuel economy in a few mores weeks. in my truck I use Castrol Edge 5W20. Also just do as the instructions tell you to add to the oil its not the entire jug for one oil change which i first thought. I highly recommend this product for every car enthusiast.

I started using this in my diesel truck, it had a loud ticking noise on tickover, this got rid of it within 3 months, I also use the fuel additive, they make a great combo, better fuel economy, perhaps more power and I'm sure longer engine life.

I have a 2007 Silverado 2500hd classic duramax. Started using hotshots product and I can’t say enough good things about them my truck runs so much smoother with them I highly recommend there product.

This is my second bottle of this and I truly feel that it helps my cord 6.7 run smoother and Quieter. I use half a bottle per oil change. Also try edt for you fuel.

there is no magic liquid that fixes your engine. But... I used this in my differentials and transfer case of a 30 year old truck and it seems to help things run smoother and quieter. I didn't expect it to improve fuel economy, and it did not.
