Max-Cleans proprietary technology targets both the intake system and combustion chamber and is effective on the entire spectrum of engines on the road, whether they are new or old, gasoline or diesel, naturally aspirated, turbocharged or supercharged.

With Max-Clean, Royal Purple has developed a product that in most cases can bring engine surfaces back to like-new clean, restoring once-lost fuel economy and performance.
The Royal Purple Max Clean does a good job cleaning the fuel system, but I was disappointed with the shipping. It took longer than I expected to arrive. The cleaner itself works well, so I'm happy with the product, but the service could have been better. Just might try another seller next time.

Cleans My Engine Like a Pro
I've been using the Royal Purple Max Clean fuel system cleaner for a few weeks now, and I really feel a difference in my car's performance. The 20 oz bottles are perfect for my needs, and getting a case of six is a great value. My engine runs smoother, and I can even tell that my fuel efficiency has improved. Definitely a solid product for anyone looking to take care of their vehicle!

Didn’t Meet My Expectations
I really wanted to like the Royal Purple Max Clean, but I didn’t see the improvements I had hoped for. My engine didn’t feel any different after using it, and honestly, I expected more from such a well-known brand. I guess it just didn’t work for my situation. Might work for others, but not for me.
