BestLine 853796001049 Premium Synthetic Engine Treatment for Gasoline Engines - 16 oz.

June 8, 2016I own 20 training motorcycles. As you can imagine, they get their fair share of abuse. Idling, numerous starts and stops, stalling, quick clutch releases at times, over-revving, shifting without the clutch disengaged, etc.Looking for real world protection, I have tried many additives over the last 20 years. Slick 50, Duralube, Lucas oil, STP, Amsoil, Johnsen’s, the list goes on. Never noticed any difference. Then I came across BestLine. Saw the information on the web, watched some videos and thought it was just another false claim. Until this:I purchased a few bottles of BestLine to try in my boat (1982 Mercruiser 140) that had a knocking sound. Changed the oil, added the recommended 10% and in less than 5 minutes the knock was gone. Completely. Idles much better. Impressive.This sparked my interest. I decided to do an experiment on a training motorcycle we no longer use anymore due to aesthetics (1990 Honda CB 125T). This training motorcycle has over 10,000 parking lot miles on it and a stock clutch. No engine repair ever. I added approximately 15% BestLine Engine Treatment, added oil to the full mark and ran it on the center stand for about 30 minutes while in second gear. I then aired up the tires, took it out for a test ride. I immediately noticed a smoother solid engagement of the clutch. It ran great!Due to my sheer morbid curiosity, I wanted to see if the CB125T would last without oil. I drained the oil, and kept the engine on and running without the drain plug in. The bike was again on the center stand in second gear. With an hour meter attached, it ran for 26+ hours. The reason it stopped running is because it ran out of gas. I’m Sold!On April 10th 2016 I added 15% BestLine in a 2005 Honda CB250 Nighthawk training motorcycle. It now has 758 miles on the oil. The oil is still gold in color. Although these are great running motorcycles, it idles smoother, shifts smoother and runs quieter.I will not only run BestLine Engine Treatment in all my training motorcycles, but in my car, truck and personal motorcycles. If BestLine Engine Treatment isn’t in your oil, you are not caring for your engine. Period.Stand by for a YouTube experiment as soon as I get help with video. I’ll SHOW proof.Thanks to the staff at BestLine that answered all my questions.Cheers,Harry E Slater JROwner/OperatorMotorcycle Training Institute

I am a Master Vw technician and I’m skeptical of just about any additives or special fluids for a car! I did some research on this and noticed some people saying good and bad things about it. Some people saying that they noticed no difference in fuel mileage or anything that would benefit even using it. I decided to give it a try as my Vw has over 200k miles, consumes 1 quart every 800 miles and gets no better than 20 mpg on the highway. I drive 200 miles a day for work so my experiment is 98% highway miles. Ultimately was unable to note any changes within the first tank of fuel. On the second tank of fuel I got 23 mpg. I though this has to be a fluke so on the third tank I actually got 25mpg. I was like ok this can’t be right. 4K miles later I’m still getting 24- 25mpg. Also I checked the oil multiple times in the 4K miles and I’m just now a half quart low. I use only Mobil 1 and always the same weight! So in my experience this additive actually works. I’m a firm believer and like I said I’m very skeptical of additives.I highly recommend this in higher mileage vehicles. Also noted that the idle is more stable now. If you are looking for the best oil additive on the market, this is my choice.

I have been wanting to get something that was better than Lucas junk. I needed something that could protect and deliver. I liked the sales pitch I seen, and I liked the tests I seen so I decided to try it and boy I tell you what. This stuff works! I own a 1984 chevy Cucv M1028A1 It has a 6.2 v8 diesel made by Detroit diesel. It was making 13 mpg in city and 18 on the highway. It was burning around 1 quart per 1500 miles with 74,000 original miles on it. Started using this stuff and within 3 services (services are 3 months regardless of mileage) My fuel mpg went up to 20 city and 28 highway, I originally had some light wear with metal shavings in engine oil, however with this stuff wear went way down and absolutely no metal shavings in filter or oil. Engine had a light upper end knock and it completely went away. Engine sounds and performs happier. And lastly, oil consumption went down to 0. This engine that previously used 1 quart of oil is now using 0 oil per service life. The oil has also stayed cleaner. Before it would get contaminated by diesel soot but now it doesn't have any contamination at all. The federal government has taken all the good quality additives out of fuel and out of oil to purposely cause engines to wear out quicker so you will buy a new one. You need to use additives in these modern lubricants especially if you operate any old vintage equipment like I do. Look no further for an oil additive this stuff really does work! You won't waste your hard earned money with this stuff!!

I purchased this and the Power train additive for a 2002 PT Cruiser. I was just hoping it would work as advertised. I have been so impressed with both products. The car has 157,000 miles and has a knock, tick, and is rough shifting until completely warm. It didnt even shift into OD for several miles into my commute. I can honestly say the car runs ALOT better. Smooth shifting and running. Shift into OD at rhe normal time, and idols quietly.I added the recommended to a fresh oil change, as well as removed 10oz of transmission fluid before adding the Bestline. Thats it!! Great stuff. Buy it! One bottle equals 2 oil changes even though it says add 10 to 15% of your oil capacity. Honestly there isnt a need. I added 5% with fantastic results.Update!!!Like every oil change, I check my oil after 500 miles. And I was 3/4 of a quart low!!! I almost had a heart attack and was ready to drain it out. Not to mention my oil was black!!! I went to the webaite and read. This stuff is a CLEANER. No biggie I topped it off and had have been driving with no more loss.I drive 300 ish miles a week. Work , kids, Walmart etc. My fuel lite comes on at 273 to 279 miles per tank. Since adding this to both engine and trans I saw 284mpt on my first fill up and have not seem my fuel lite before 300mpt best being 307. Thats well over a 1.5mpg improvement.Fresh oil change tomorrow 10/25/15 and I will add the rest of the bottle 8oz. Oil is really dark cant waot to see how a clean engine runs with this stuff. Im only 1400 miles into a 3000 mile change.

Added this with an oil change on my 2009 Toyo Corolla. I went about doing my usual errands and a few days later I noticed a 2mpg increase according to the automated dash calculation. I wasn’t trying to baby the gas petal, I just did my usual driving. After listening under the hood I think it’s a bit quieter too. So I guess there is something positive about this additive. Can’t complain. I think I’ll Ty it in my bigger Sequoia next.
