Review of Royal Purple Max-Clean
The Royal Purple Max Clean, which is EPA-Carb compliant, promises to clean almost 100% of your fuel system in one treatment. This is a massive offer and requires further analysis. Royal Purple is made of synthetic ingredients capable of cleaning your carburetor, injectors, combustion chambers, and intake valves.
Fuel improvement based on several independent tests show an increase of 6% while horsepower improves by up to 5%. Idling becomes smoother and stalling infrequent. It can reduce NOx by 12% and hydrocarbon by 12% on the average. At the same time, the wear and tear on spark plugs is slowed down and deposits and corrosion on your engine as well as tailpipe emissions (18%) are reduced. The product can be used for diesel, gasoline, biofuel, and all ethanol-powered engines, and on 2 and 4-cycle engines.
For a car with a 13-gallon tank, one bottle of Royal Purple is good for 2 full tanks however based on user experience, it is important to keep an eye on your MPG because it can decrease slightly. It is also recommended that you do not use the product every time you buy fuel. You might want to use it after 2 months or 8 full tanks.
Another issue you may have with this product is the container. It’s not easy to pour it into your fuel tank without spilling some. You should buy a funnel to be used only for this product and this will be an additional $5 investment. The company has offered rebate to customers unsatisfied with the product but it is a tedious process and not a full rebate. Still, it is one of the best in the market so the chances of wanting a rebate are relatively low.
Royal Purple Max Clean is definitely a product to be considered if you are concerned about dirty fuel. Majority of the feedback is positive even on old vehicles and vehicles that run on diesel, biofuel, or ethanol. The downside is minimal and can easily be addressed with simple solutions that do not cost a lot. This product is highly recommended.
