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

Been using 64oz in every oil change on a Cummins ISX every 15,000 miles for a little over 2 years now. Raised oil pressure from 34psi to 38psi at about 1,400rpm and almost cut about 1/2 gal oil consumption between oil changes. Motor currently has 1.2 million miles on overhaul. Best additive on the market in my opinion.

When I used it to treat my whining power steering pump. I removed the fluid in the reservoir and added new along with the recommended amount per quart. Worked just fine and whine is gone.

Every 5000 miles at oil change

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!

My 2023 Denali is quieter and turbo spools a little quicker won’t run my truck without this treatment.

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.

This product definitely works ,I have a 2004 Chevy Silverado with a 5.3 V8 lifter tick on start but goes away.I recently did a 1400 mile trip Florida from NC ,My first fill-up truck indicated 338miles normal , during the trip I was thinking I he feel up mileage so get worse because I was really laying the hammer down 75 to 80 mph my mpg indicator normally stay on 13mpg but during the trip it was on up to 14.7.My 2nd fill-up was 358miles per tank 3rd fill said 373 4th fill said 379 my last fill said 381 so something inthis additive is actually reducing friction ,and my lifter tick on startup is almost gone so this additive is worth the price

A good product that improved the performance of my Toyota truck and Honda generator at an affordable price.

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.

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 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.

good product have ordered 3 times now . this time though it arrived leaking

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.
