Royal Purple Max-Clean Fuel System Cleaner and Stabilizer 11722 20 Ounce

Another fine product! Very well priced! Arrived well packaged with no leakage issues. Thank you!

Seen a bunch of videos recommending this detergent cleaner for the jets. Just had to change the coil just making sure the jets are good too. I really appreciated the long nozzle it comes with.

The only stuff I put in my vehicle. Highly recommend.

Can’t give this one 5 stars only because idk if it did or didn’t clean anything.My car definitely didn’t feel any different and the efficiency of the fuel wasn’t affected at all so 🤷🏽‍♂️If I helped or hurt the vehicle

I bought a used 2002 Porsche Boxster with 133K miles for cheap with the check engine light on at the time. Seller stated that it was on when he bought it. The car ran fine so I bought it anyway, considering the price. I put this product in and filled the tank. Almost immediately the car was running smoother, and soon the CEL went out - and has not returned. I use this every winter just to stabilize the fuel as I live in a snowy climate and hardly ever drive it. Every spring it fires right up and runs great.

This is the best .

if you have a car that you are putting into storage for most of the year, buy a can of this and use it as directed. Drive your car long enough to get the Tank down to 1/4 tank or a bit lower. Then Pour a can of this into your near-empty tank and Immediately drive your car to the gas station and fill it up (the gas pouring down into the tank with the Max clean already added will cause it to mix Perfectly with your freshly pumped fuel). Then drive home and put your car in the garage for winter storage. Disconnect the battery and add a few extra psi to the tires (to prevent flat spots). And then come back 3-4 (or even 9-10 months') later and your car will start right up (and run smoother than ever). There is air above your fuel in the empty part of your tank so by storing your car with a full tank topped off you have pushed all the air that is above your fuel out of the tank (further slowing down the decay/deterioration of your fuel). Topping off your tank without "splashing your shoes" is the difficult part. :)The 1 question i have is: can this product (and should it) be used in combination with the Max Boost octane booster? or is it NOT ok to mix the 2 products?You used to be able to get 94 crystal clear Amoco Ultimate gasoline near my house at the gas station. Now you are LUCKY to be able to get 91 (or 92 if you are very lucky) crappy gas (that has been Further diluted with ethanol and water).If you read Car and Driver whenever they test Cars that absolutely reQuire high octane fuel (like the Nissan GTR) it preforms weak in their tests b/c of the unavailability of good quality 93 octane fuel. This is the United States of America folks. We basically can't get good quality fuel any more. The best available is BP 93 octane, but i have to drive kinda far to get to the nearest BP station from my house. It's all Wawa gas stations now with 91 or 92 10-15% diluted ethanol/water gasoline everywhere!I am investigating the use of The royal purple Max Boost to see if it helps with this problem of being able to get good gas anymore in America. And car and driver, if you are reading this: the next time you test the GTR (or a saleen Mustang, Cadillac cts-V) or any car that "must-have" 93 or better octane Fuel, try a can of Max boost. Or better yet, Test the car WITHOUT and then WITH a can of Max boost and see if the GTR puts out the advertised Horsepower and Acceleration numbers. If all you can find is 91 pump octane that is cut with ethanol and water, man what a waste of a $100,000+ sports car.

Good item. Should work well for what I need.
