16.9 Oz Rislone Nano Prime Synthetic Engine Oil Additive Review

When oil only can't live up to it's Words on them bottles. this Snake oil gets Job Done. try and reinvested on your Car. thank me later

After driving my truck everyday for years I notice any difference in performance. This additive made it run smoother and quieter and maybe a bit better acceleration on take off. I think it's worth the price.

Noticed an immediate difference. I take very good care of my car, best oil, change often, always doing preventive maintenance. This stuff made my engine, which already ran great, run even better. I'll add it every 6 months or so

I quieted an old generator.Its an oil viscosity thickner but has top of the line synthetic additives for longer engine life

Genuinely good stuff. My aircooled vw bug is running much cooler (no radiator on these, so the oil is the coolant). The tappet noise is much quieter.

I'm a freak when it comes to buying so called snake oils "engine additives." I really have been since watching my first Dura Lube commercial many many years ago! I've used them all, but I really think this is my favorite. I drive my vehicles until they have too many miles to drive anymore. I firmly believe that a lot of these additive do help the engines. I have a 2007 Jeep Commander with 280,000 miles on the original engine and the Dodge Ram with 279,000 miles on the original HEMI. Both run…

Can't say if the one being advertised all over the place that cost more money of a different company is worth the price or not. But I can tell you in my 20 year old van just turning 200,000 miles I had a tapping sound that would not go away. One bottle during an oil change - no tapping and I swear it seems engine is stronger!

Used this today during an oil change. My engine has high mileage so I threw this in along with Quaker State high mileage oil. Within the first 30 miles I noticed that I can barely here the engine running at a red light. This stuff really works fantastic. Also a very smooth acceleration. Can’t wait to see if any more improvements occur while this is in the engine. One bit of advice, shake the bottle VERY WELL.

I am a master level ASE Technitian that currently works at a dealership. I came across the Cam Phaser rattle issue fixing a car. There is a TSB and service instructions for this issue. The cam timing gear looses its oil and is empty on startup then rattles until it fills. UpdateYears later, my wife buys a 2014 Camry with the 2.5L 4 cyl with Dual VVT. Yes, it rattles. SO, I used this product (saw it on a tech car show). It quieted the rattle and shortened the duration of rattle at startup. What…

It works! I invented this. Not only it works in actually application (automotive), but also during testing after I formulated it. Outstanding results!

Drove new Ram 1500 truck towing auto trailer on back to Spokane from Oregon to pick up a car and trailer it home. Poured this into the engine (hemi) prior to leaving on the trip. Prior to using I was getting 21.8 miles per gallon and after putting it in the engine and even while towing a trailer (empty trailer) it jumped to 22.7. I was shocked. On the way back (with car on trailer) I got 16.1 mpg and was very pleased. The truck had 15,400.2 miles on it when the Nano Prime was installed. (yes…

Honestly, my engine after 1000 mls or so seems to idle much quieter, not as noisy as before. The engine at 90K miles feels more peppy and gas seems to last longer.I will definitely use again for my next oil change.

I added this after and oil change and left room for the contents. I added while the engine was running. You could see and hear the engine smooth out and run better!

First time I've tried this product but so far I'm happy with the results. Usually I'm not much of an additive guy but my hyundai 3.8 engine is getting on in mileage. 177k on the odometer right now. I drive mostly highway miles but lately the engine just hasn't been quite as smooth or quiet as it used to be. The motor takes 5.5 quarts so I did an oil change and used this product as my .5 quarts. After running it for a couple hundred miles the engine is smoother and quieter. Much like it used to…

I use risoline on all of my vehicles at all oil change intervals and they are not complaining at all. My everyday driver and plow truck just hit 208000mi and my other two vehicles are on their way. I use this product faithfully and think it's a great value for the money.

Stuff was a why not I'll try it and see since the reviews on other like products were good. It took my 98 Lexus ES and smoothed out the idle and it didn't burn as much oil on the first bottle! I drove all around Arizona and back to Wisconsin and had no issues with anything engine wise. I will definitely be adding this to all of my cars from now on!

Installed in 2005 Explorer with 200,000 miles After about 500 miles engine was quieter and smoother. a 1 mpg increase has held steady over the next 4500 miles.Mixed w/Quaker State conventional oil

I have a 1999 Jeep Cherokee with a 4.0 liter inline six. great engine, but I kept getting a miss fire in cylinder 6. One mechanic wanted to do a valve and head job, but a trusted mechnic, Johnny, who has a jeep 4.0 liter with 250,000 miles, said it was probably a sticking valve and told me me add Rislone. I did and some 2000 miles later, no more missfires.
