Safe & Effective - Engine Oil Additive/Treatment, Diamond Nano-Lube by BestLine Racing. Reduces Friction Up to 60% – For Gas & Diesel Engines – More Power, Engine Life & Fuel Economy

I have purchased a bunch of oil. Additives, they all seem to do the job pretty good. But this one takes it all the way does make a big difference engine runs, smoother and quieter. Fuel efficiency, I can see a little bit not too much, but I am pleased with the product. I just purchased another bottle for my Chevy truck. Now the first bottle was put into a mercedes benz, GLC300 and boy, what a difference

I have used this on three different cars. A 2001 Lexus RX 300 sold with 200k and buttery smooth engine, a 2010 Mazda 6 sold recently with 98k again engine solid and smooth, 2019 Hyundai Santa Fe with the 2.4l Thetha II engine. Bought that Hyundai with 11 miles and since day one I have been using this product now going on 118.5k the engine still going strong, no sludge, no oil burning, no compression issues and no issues to report. I have put that engine to thousands of miles from West to East coast multiple times. Still going strong and hope it hits that 200k without issues. I happily recommend this product it seems like the engine is quieter, smoother on cold starts and the engine temp doesn't seem faced no matter the Summers in the Southern U.S.

So I bought this product about a year ago on a whim, I don't even remember how I found it now. We have a 2008 Ford Crown Victoria police interceptor with 166,000 miles. It does not get used much anymore, actually in the past year we've only driven 2,000 miles. I noticed a couple of years ago that the first few seconds of cold startups there was a rattle from the timing tensioner (very common on the 4.6). It would go away after a few seconds but very annoying, and may cause wear overtime. Enter Bestline - added a full bottle at oil change. Literally within the first two days I noticed there was no more timing chain tensioner rattle! I couldn't believe it but here we are a year later with the same results. I haven't kept good track of mileage over the last year due to the low usage I don't often fill up the car all the way. Changed the oil a few months ago in our 2018 Mazda CX-9 turbo and decided to give this a go with minimal expectations as it runs very well, currently has 58,000 miles. The motor ran well as it did before, but the surprise came on the first cold start here in Iowa winter. I immediately noticed that in very cold temperatures, there was substantially less vibration on cold start. One other thing to note, at first I did not think that the mpg was affected. However now with almost 5,000 miles with the best line, when the conditions are the same it is definitely improved. I use the Fuelly app so it's easy to track the mileage. In the last 10 fill ups my average is up about 1 mile per gallon. Previously, when I drove 100% City mileage, the Mazda averages between 17 and 19. But the last two tanks have been 21.3 and 20.8 respectively. Highway would be a great test that's the best I've gotten before was 28, will have to test in the future. I'm not sure if this product needs time to do its thing? But we'll see if this trend continues. Needless to say, I was pretty skeptical but will keep using Best line in all of my gas powered vehicles 👍

I've been using this product in my restored and modded 91' MX5. The engine has 244K original miles. Prior to using Bestline engine treatment my engine ran fine on 10W40, but had the normal sluggish cold starts in winter, lifter ticks,m etc. Since using the older and now apparently improved product, I have noticed a virtually instant improvement in idling smoothness, reduction of engine noise and lack of lifter noises. Most importantly to me, cold starts are as smooth as warmed up running, and this is essentially what I initially bought the product for, - less initial start up wear. The engines now springs to life with no stumble, hesitation or lifter ticking. The engine also seems to respond better and revs faster. I did change to 0W40 and this also has a lot to do with the changed revving characteristics and less resistance but I noticed this change even before switching from 10W40 to 0W40. My original 244K mile miata engine runs like a newly broken in engine and better than it did ten years ago. Edit: now at 247K miles, my engine engine idles smooth and quiet like new, without lifter ticking and at a rock steady 850 rpm. Start ups are smooth and effortless with no stumbles or rough warming, even on the coldest PNW mornings. I accept the $20 price tag as I now do my own oil changes and still average a bit below the oil change chains despite getting far better products into my engine and oil filter. I don't know what nano tech black magic this is but my car loves it and so do I.

The manufacturer of my car does not recommend using oil additives. Harrumph. My 2004 car runs just a little bit better when I add this stuff. 240,000 miles, and she purrs like a kitten.

I am super impressed with this product. My Supercharged Grand Prix has never run so strong, in the 23 years I have owned it. The car ran well before I added this product. Now it feels like I picked up a lot more horsepower. I plan on adding this product to all my vehicles. Just returned from driving it on a 500 mile trip. I averaged 25 MPG. Best I ever got.

I am thoroughly impressed with the BestLine Racing Diamond Nano-Lube Engine Oil Treatment! This product has transformed the performance of my vehicle's engine in ways I didn't expect. The difference was noticeable almost immediately after adding the oil treatment to my engine. The engine runs smoother and quieter, with reduced friction and heat. I've also experienced improved fuel efficiency, which is a significant bonus. What sets this oil treatment apart is its advanced nano-lubrication technology. It creates a protective barrier that enhances engine longevity and performance, even under extreme conditions. I feel more confident in my engine's durability and reliability, knowing it's protected by BestLine's innovative formula. Application was straightforward, and the results have been exceptional. Whether you're looking to optimize engine performance, reduce wear and tear, or improve fuel economy, I highly recommend giving BestLine Racing Diamond Nano-Lube Engine Oil Treatment a try. It's a game-changer!

The bestlune oil treatment did nothing to improve my truck. It didn't make it run smoother, or quieter. It did improve my had mileage either. 2022 GMC sierra 1500 5.3l with 142000 miles. I added 2 bottles in my 8 quart capacity engine.

I can't rate this product enough forget liquid moli ceratec and Lucas oil stabiliser fully synthetic or not and slick 50 engine treatment all of them are not even in the same league. This stuff lubricates and coats very well so much so that my engine which normally takes about 15 minutes to get the engine up to temperature oil temp by the way, after putting this in my engine it actually took around 5 min longer to get to temperature this indicates that the lubricity had increased I highly recommend it not cheap but worth it, my car is a 2012 Merc S63 V8 twin turbo just for information purposes.

I bought this with the intention of increasing engine life of my bike. For the 1st time any additive seems to make a difference. This's a brand new engine (KTM 390) Turns out it did NOT increase the engine life. My engine has started to consume oil at 15K kms. I added 11% of engine oil volume (177.5ml per 1600ml). I bought this viewing project farm tests.
