853796001049 Premium Synthetic Engine Treatment for Gasoline Engines - 12 oz.

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.

The description of sheerness and warmth doesn’t apply. This is hands down the best additive I have ever used in both my semi truck and personal truck. My motor went from one sticky valve to silent. I got better mileage and my oil stays cleaner longer. I also noticed after the first oil change how much heavier the filter was. It cleans out far more deposits from your engine and on the second change I noticed cleaner oil. I have talked with the CEO about the way this is made and what it’s been tested on. I made this product a staple for my business. He was very helpful and gave me lots of information about the product and how it functions. This product has been mostly used by our military vehicles. I was introduced to it by a helicopter pilot. This isn’t a gimmick where most of the product is just water or motor oil sold for double or triple the cost. If you want quality and want to see results the first oil change try this out. Especially on an engine with 100,000 miles or more it makes a noticeable difference. As with all things we buy look it up do a little research you’ll find as I have this is worth the money.

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.

This stuff is by far the best product that I have used to treat a worn out engine. The tapping that was coming from my bearing had really quited down after I put this in. BUT on my other vehical that consumes alot of oil, it did nothing. I realized this product makes a difference, but you would have to know what youre looking for. Better than lucas in my opinion since it quiets the engine down alot. Will be trying on my new Jeep and seeing what difference I get in MPG.

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!!
