This is most likely the best fuel additive I have ever used as far as actual real-world improvement in fuel consumption. I have a 10 years old diesel vehicle which has been slowly increasing in fuel consumption, so I purchased this item. I added the content into the fuel tank when there was about 1/4 a tank left and let it run down until as far as I was willing (about 50km left in the tank). The next fill up, I did not notice a very noticeable change, but from the next tank on, I have been getting 50-70km more out of each tank of fuel. For reference, my tank is 65L and I've been getting about 740km out of a tank. I generally do a lot of hilly 60km/h drive (50%). a little bit of town driving (probably about 20%) and a little bit of highway (20-30%). Now, after the treatment, using the same fuel, same driving pattern, I am getting approximately 800km out of a tank on average. I think I might buy another one and treat it again. It'll probably clean the system further and give me better results.

seems to be working.Royal purple makes a great oil that is expensive but cleans your engine as it drives.keeps the carbon down.Seems like the purple coloured injector cleaner works too.I used it to do a piston soak for stuck rings full of carbon.Engine runs better.

I purchased a 20 oz can of this at AutoZone ($18.99 + tax). I used the can with Sunoco Super Unleaded gas in my 2019 F-150 with the V-8 engine. I then travelled from VA to GA (8 hour drive) and I definitely noticed a difference. Pick up to merge onto the highway and passing other vehicles was a lot better and I logged 20.2 miles per gallon, which is at least an improvement of 2 MPG. My truck also idled so great that you wouldn’t even think it was running. Highly recommend this product!
