Review: Say what you want but oil treatments are the truth!!! - This stuff is magic in a bottle. It will save you so much money in both the short term, and the long term. We are going to get in to the nitty gritty with the GOOD, BAD & the UGLY. Let's do it! Disclaimer: This was used in a Toyota Prius Gen 2 2004-2009 GOOD: Treats your engine, and treats it well Idling is smoother than butter (engine idles quietly, even in cold temperatures) MPG increase (Instantly got an increase of 5+ mpg, even with heat on all winter) The Savings!!! (This with a conventional oil change costs 60 in total versus getting a full synthetic oil change which runs 85+) Engine runs extremely cool and quiet even with highway miles at 60+ mph Everything goes quiet the minute you add it and drive about 20 miles (no knocking sounds, friction noise, rough idles, nothing O.O) Made in the USA (quite the shocker to see these nowadays, especially effective products O.O) BAD: Expensive (this is when you compare to other fuel additives but overall, it is still priced competitively) UGLY: The opening is funny to pour from, not really a problem if you have a funnel, but keep this in mind if you are pouring without one. Overall, this product is blazing hot Doritos and then some. You are saving money, cleaning your engine, getting rid of existing problems, and giving your car new life. All while getting the cheapest oil change and adding this simple additive. You can't go wrong with this product. Stop reading, buy immediately, and bring new life to your engine!
Review: Great product- did things I did not think that it would - 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 👍

## Questions & Answers

**Q: Can this be used in lawn mowers?**
A: Yes! lawnmowers run with more power to cut through tall wet grass with more power and life

**Q: Why was product 16 oz reduced to 12 oz?**
A: The old formula needed 16 oz to do what the new superior formula in 12 oz can do today. The new product in the black bottle outperforms the older grey 16 oz bottle.

**Q: Is this a thick liquid or is it thin? I’m worried about it changing oil viscosity**
A: Hi and great question. Using the BestLine Engine treatment does not change the viscosity of your oil. We use a 20 weight base oil and your only using 12-ounces for every 5- quarts of your regular oil.

**Q: Can i put two bottles of this product in my truck engine 5.3?**
A: Hi, yes you can add 2 bottles for even better results. The dosage rate for daily drivers, not high performance, is 1 bottle per 5 quarts of oil. If you want the best results use 2 bottles per 5 quarts of oil, that's what we do with our high-performance and race cars.

### ⭐⭐⭐⭐⭐ Actually works as advertised
*by A***T on July 29, 2020*

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.
