## Customer Reviews

### ⭐⭐⭐⭐⭐ User for life!
*by S***N on October 1, 2015*

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.

### ⭐⭐⭐⭐⭐ Great product that actually works
*by A***N on December 1, 2020*

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.

### ⭐⭐⭐⭐⭐ Best oil supplement on the market
*by G***E on September 25, 2021*

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.
