Royal Purple Max-Atomizer 18000 Fuel Injector Cleaner, 6 fl oz

I am generally very skeptical about these miracle cure in a bottle products but this royal purple atomizer worked remarkably well for me. I had noticed a decrease in fuel mileage, rough idle and an overall lack of performance in a 2.3 liter GDI engine. Also the fuel trims were off quite a bit. After one bottle and a tank of gas, the difference it truly remarkable. The idle is perfectly smooth and there is a noticeable improvement in performance. I expect fuel mileage will improve as well but too early to tell. Fuel trims are spot on. I had forgotten how wonderful this engine performs! Will this fix all problems, certainly not but it absolutely made a huge improvement to GDI fuel injectors.

My 5-year-old Volvo with 48,000 miles has consistently averaged 25 miles per gallon, according to my app. Now, after 2 months of a one-time use, I'm averaging 26.9 mpg. So, I believe it does help improve mileage and performance. I'm going to use it every 10,000 miles. Try it, you'll like it.

The item has the proper mix of chemicals to be effective. It contains PEA which is the active ingredient in performing as advertised. Easy to use but may take a bit of driving to notice results. More effective on vehicles with moderate to high mileage as new low mileage vehicles don't usually have build up on fuel injectors.

I looked at a few different fuel, injector claims and this one Royal really is the best. I added it to the gas tank. Fill the gas tank with gas. You could fill the difference in the engine within 100 miles. It's absolute awesome value for money simply the best.

At our last oil change, I used this together with an oil treatment product. The results have been great. The engine runs better and idles smoothly. This was better than expected and like an instant tune-up.

Great stuff if you can find it. Especially if you buy from a non high tier gas station. Also put in small equipment. This and a little Stabil in its full tank, starts right up after winter. No hiccups.

Walmart always had great prices on things. Whenever it gets delivered tot eh back door, like it says right below my name on the shipping tag, it is always 5 stars.

This Royal Purple fuel additive for my 2019 Hyundai sonata GDI engine is one of the best ones that I've tried.

I bought this product and put it in my truck.I didnt notice any difference because my truck was too old. I had high milage. Scotty Kilmer recomended it on his Youtube channel so I thought it could help

This product is excellent, however Walmart said they delivered it and it was not in the open bag. They gave me a refund but if you want THIS product, go pick it up yourself.
