Review: Additive that actually improves Fuel Consumption - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00B1VBQRS | | Brand | Royal Purple | | Brand Name | Royal Purple | | Contains Liquid Contents | Yes | | Contains Liquid Contents? | Yes | | Customer Reviews | 4.6 out of 5 stars 2,727 Reviews | | Global Trade Identification Number | 00641330117220 | | Item Weight | 1.25 Pounds | | Model Number | 11722 | | Net Quantity | 1.0 Count | | Part Number | 11722 | | UPC | 641330117220 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Royal Purple - **Contains Liquid Contents:** Yes - **Item Weight:** 1.3 Pounds - **Number of Items:** 1 - **Unit Count:** 1.0 Count ## Images ![Royal Purple 11722 Max-Clean Fuel System Cleaner and Stabilizer - 20 oz. - Image 1](https://m.media-amazon.com/images/I/7178Kyc-yJL.jpg) ![Royal Purple 11722 Max-Clean Fuel System Cleaner and Stabilizer - 20 oz. - Image 2](https://m.media-amazon.com/images/I/711r02FWmqL.jpg) ![Royal Purple 11722 Max-Clean Fuel System Cleaner and Stabilizer - 20 oz. - Image 3](https://m.media-amazon.com/images/I/41JNMScCkTL.jpg) ## Questions & Answers **Q: my tank holds 33 gallons, would i have to fill it up only will 20 gallons after i pour in Max Clean or could i fill right up?** A: Put in a bottle & fill your tank 3/4 of the way up. That way you get the improved performance, but only have to buy one bottle. That's what I do as I have a 26 gallon tank. **Q: How to use this ? Can I just put this to the fuel tank ?** A: Dump it in the fuel tank and fill it up with gas. This large can will treat up to 20 Gallons. I use it in my motorcycle, so I just put a small amount in. It also has a fuel stabilizer in it which is good cause I don't ride the bike that often. **Q: Does this work in small gas engines?** A: What do u mean by small gas engines? Im running a 1500cc engine and works well with it. Is this small enough? **Q: Does MaxClean come with the application funnel for capless fuel tanks like some of their other products?** A: It does come with a plastic funnel that attaches to the bottle. Depends what fuel your vehicle takes if it will work or not if it's a caplesss filler neck vehicle tho. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Super producto para probar. *by R***Z on 21 April 2026* Es el producto tal cual lo solicité, aunque tardo un poco en llegar, el Royal Purple Max Clean me satisface tenerlo, ahora a probarlo. ### ⭐⭐⭐⭐⭐ Additive that actually improves Fuel Consumption *by K***8 on 28 April 2026* This is most likely the best fuel additive I have ever used as far as actual real-world improvement in fuel consumption.
