Does Royal Purple Fuel Max Cleaner Actually Work (with Proof)?

  • In this video I test Royal Purple Max Clean Fuel System Cleaner in a Ford Explorer. I use a borescope camera to look into the engine and see how dirty the engine is before the fuel treatment and then after the fuel treatment. This is the first time I looked at intake runners and valves, and I also looked at the piston head.
    I followed the instructions on the container and Royal Purple did clean some carbon off the intake runners, valves, and piston heads. This is the best in fuel system cleaner I have used that goes in the gas (so far)

      And you gotta use top tier fuel which contains detergents that help clean as you go. That was a game changer for our vehicles. My lovely Toyota would hardly go at only 50k because of gas that was only a couple dollars cheaper per tank but just let that carbon build right on up because they didn’t add the detergents that clean the system all times of operation.

    I used to work for a dealership for many years. One product worked so well, it had to be diluted with gasoline because it was so powerful (unless the job called for 100%) Its called GM Top engine cleaner. You may have to ask at parts department for it, it's not expensive (maybe $6-10) a can. You can use it many ways but I seen it spayed into the throttle body over 15 minutes (with a pressured air adaptor). I would like to see how it works in your videos.

    I think even the best cleaners will need at least 3 applications, in order to flush out the carbon that broke loose and deposited somewhere else.
    Also, the reason the cleaner pistons don't see as much result is that those pistons are not getting as much fuel. Since the cleaner is in the fuel, those pistons won't clean as well. It's usually the pistons furthest from the fuel pump, at the front of the engine that will be cleanest.

    Chris, Love your videos. Your a favorite and the public is in debt to your time and experience. I certainly subscribed. I found this series so informative and wanted to express my appreciation to you. I do have a question to expand on your testing as I saw another video that came at this from a different angle - Water. I saw that water can be more effective and it seem to make sense. The products that burn hotter clean the best. highways driving is the best conditions. Steam is much hotter and may be more effective agent than these cleaning products. Logically it makes sense but I have no data to support my perceived logic from my research. What are your thoughts on using water to clean out carbon deposits? How would it compare to these products? Thanks. Fan of ChrisFixOops, saw that others have commented on the water approach. I'll read up.

So if it's trash in the can then it is trash in a can that works, I bet you're the guy who says clean them yourself which obviously yes that is the best way to do it is to get a valve job done but if you're just trying to get some simple cleaning and improve performance and life of the vehicle this absolutely helps on a measurable scale nice childish comment dude.

    For anyone wondering about this stuff I use it every oil change that I do. I recently had to change my MDS solenoids in my 5.7L hemi. while doing that I had to pull my intake and I looked at my intake in my heads and they still look brand new no carbon at all. Same with the valves look brand new. took my borescope to the pistons thru my spark plugs they look good as well, not near as good looking as the intake runner or valves but a thin coat of carbon. But for my cars miles looks great. My car has 250,000mi on it and I have had it 7years and used this every oil change. I do an oil change every 5-7k miles. So I would say that if you use it regularly you will get the best results.

    You've got some great vids for the DYI person who likes to keep their car or truck clean and maintained. I have one issue though with some of the 'fuel cleaner' vids. I was always taught to not let your vehicle go below a quarter tank of gas so if any garbage is in their it won't all hit your engine at once. In this vid you instructed your friend to drive the truck til it was almost out of gas and then you use the cleaners. Is this to also get rid of any garbage in the tank or....??? Thanks and keep the vids rollin'!

    Old video new comment. I've been using this stuff for the past few months in my vehicles and have noticed a serious difference with how they exhaust.... I always add the max clean when engines at 205° and drive aggressively to clean the valve seats and injectors. Looking at the top of the piston head you will see some of the carbon eaten away.... But where you're really wanting it to eat carbon away is on the cylinder wall so the rings can compress freely the way they do on a new engine.... Using this every other time I get gas... I have noticed how much cleaner my fuel system is, and it even saved me a fuel filter change on a project truck I bought that was straight piped and ran lean for a LONG time.... Royal purple is worth the money. Lucas and techron have been successful for me as well, but this stuff has always been the most effective as far as performance. Chrisfixx makes great videos but I've noticed he is more focused on the top of the piston head than where.the.rings meet the cylinder wall. Those rings HAVE to stay clean in order for that engine to survive for a long time. Either way, love these videos!

    I've been using RP Max clean since this video came out. Figured I'd share my experiences over the years for the folks that will end up here later.
    Vehicle 1- 2004 Chevy Tahoe 5.3L . Can't say I really noticed any improvement in MPG, but after putting in a few cans, the truck did accelerate smoother and seemed to have a little bit more bottom end power.
    Vehicle 2- 2015 Ford Taurus SHO 3.5L EcoBoost. I didn't notice any good or bad with using Max Clean. The vehicle already ran fine with no issues. it just didn't seem worth the money with this specific vehicle. It's worth noting that the 3.5L EB is a direct injection engine, so the valves never got fuel+Max Clean sprayed on them.
    Vehicle 3- 2020 Nissan Murano 3.5L V6. This was when Iearned that Max Clean is best used before heading out on a road trip. I noticed the car did idle and accelerate smoother after a 3.5 hour drive with Max Clean. There were way too many variables on these trips (construction closures, stop and go driving due to accidents, weather, etc.) for me to say anything about fuel economy. Only paying $20 for noticeably smoother idling and acceleration doesn't seem like a bad deal at all.

    I've used Berryman's B-12 Chemtool for years. Now I've been a mechanic since the early '70s. Before the time of computer controlled fuel injection, carbs were the norm and quite frankly, they were a dirtier affair, as far as the engine internals were concerned. It wasn't just carbon build-up inside the cylinders that affected an engine's life/performance, but the oil would be contaminated too from excess fuel getting past the rings. The points-based ignition systems and the whole thing would be lucky to last 100k miles. Spark Plugs and points would need to be changed every 12K miles. Today, engine life expectancy is twice that or more. Plus tune-up frequency is between 60-100K miles. So life is a lot different today for most engines.
    As I said, I've found Chemtool to be a great general purpose brake and gunk cleaner. It removes gasoline varnish while leaving most other brands looking stupid. I have never tried testing it using a borescope, but you might want to add B-12 Chemtool it to your testing arsenal.
    In my day, I used to recommend a customer run a gallon of Diesel fuel through the gas tank every fourth or fifth tank full. I can tell you my results were engines with clean top-ends, heads that didn't have a nasty build-up of crud/wax/grease around the valve springs or in the oil galleys. (This is what also leads to internal engine wear.) The pistons and valves also appeared to be significantly cleaner over the long haul. The real difference was in their mileage - most of my customers who followed this advice would expect another 50-100k miles out of their rides. From personal experience, I had a '68 Mustang 302 that went over 238K miles before I broke it down (radiator leak caused it to over heat) and when I examined it - it was amazing, really, after this kind of care. Yes, the piston rings cracked from the heat, but the engine was very clean inside and throughout.
    Besides the diesel or Chemtool, you might also want to try adding a small stream of water to your intake, like you did with the seafoam cleaner, limit the amount injected through a small hose. Again, do not use enough to create hydro-lock, but enough to vaporize within the combustion chamber while running. The expanding stream of steam will often times blow away most of the larger (and more porous) hunks of attached carbon.
    I think the diesel fuel works the same way as it has a very low octane count. Diesel is oily and wet, and will tend to saturate in to the carbon deposits. It is not ignited by the spark plug or compression, however. Instead, in this case, the diesel is ignited by the gasoline. This gives the wet diesel an opportunity to wet then blow-off the carbon deposit(s). YMMV. But since you were interested in running these tests, I thought you might be interested in giving these age-old tests a run through as well. IF you try the diesel, I would suggest you do so with premium fuel - and non-ethanol added fuel to boot. The increased octane will help offset the lower octane rating of the diesel. (You should be able to find premium recreational fuels at some local gas stations. You might want to to call around to locate a retailer near you. Most motorcycle enthusiasts prefer this blend.)
    kind regards,
    Michael

    Hey Chris thank you for all your videos and all of us enjoy every single one of them! With that said and these fuel system cleaners, when it comes to the combustion chamber I wonder if it would just be better to run the highest octane available as well as some fuel stations have racing fuel that is 100 octane plus and just run your car really hard causing higher fuel combustion temperatures there for getting rid of some of the carbon that would have the same effect. so somebody who puts this in their vehicle when they're getting on the freeway happens to floor it causing high RPMs and higher temperatures in the combustion chamber. Maybe possibly adding a higher octane racing fuel or 91 + adding the fuel system cleaner to it as well as a octane booster that is sold at most automotive stores. This would be the cleaner and a higher octane booster causing a higher temperature in the cylinder possibly cleaning out some of this carbon buildup. thank you so much for your videos look forward to the next one.

      Higher octane doesn't necessarily mean better for your car. Most cars are engineered and tuned for specific octane ratios. Going below or above can cause issues. Mostly less power and milage due to the car not having the ability to ignite that mixture effectively. Resulting in unused/unspent fuel. You'll smell gas when u drive.

      Dolby 109 A failed intake manifold gasket is the reason for the coolant entering through the intake ports because the coolant crossover between the two cylinder heads is leaking.
      The intake gasket is used not only to seal the intake runners but also the coolant crossover.
      When the intake manifold fails the coolant can escape from the crossover and run freely down the intake ports of the head and it usually fills the spark plug wells causing a misfire as well.
      An intake manifold gasket failure is often misdiagnosed as a head gasket failure because some of the symptoms are similar.

I believe that they should be approached as a maintenance method. You said that carbon build up is created “over time” so it only makes sense that these thing be used in intervals in order to get drastic results. For example before every oil change or after x amount of miles. I assume that it will take time to get results like with anything else. Those are my thoughts, let me know what you think!

    My Dad has said for some time he doubts any fuel injector cleaner can do what it claims based on % in the fuel system. It would be like putting one bottle of shampoo in a huge city water tower and expecting that to be enough to wash everyone's clothes or for everyone taking a shower to get clean from that alone.
    He says the reason he uses some periodically is to clean the tiny pin holes in his injectors. He claims that just the tiniest bit of varnish build up or carbon and the spray pattern goes from fine mist to rather large droplets.
    He claims it would take a much larger concentration by volume of the ingredients in fuel injector cleaners to ever hope to make a meaningful impact on piston deposits.He is talking about Amine based cleaners not cheap crude solvents since gas is already rather solvent like.
    Anyone that has ever had to replace a cylinder head knows how easy it is to clean all the carbon off the top of a piston with a solvent brush and a few splashes of liquid B12 Chemtool. Dropping a can of B12 Chemtool into the tank is not going to do any better then the other "Injector/Fuel System Cleaners" it always comes back to concentration. You can only dilute something so much and still have it do anything productive. If it was ran at high concentrations though your octane number migh drop enough to cause detonation which is no good at all.

If the fuel is well controled then the carbon is so minor that is it likely not much of an issue today. Sure it is their but it is so little compared to carburated vehicles that the carbon cleaning effects are not that big of a deal compared to how they are advertised.

      Pretty sure a little bit of water isn't bad, but water doesn't compress and instead turns into steam which cleans some of the carbon off. Eric's got a video on it so I assume it's not that bad.

    What happens if you combine multiple fuel system cleaning products for one engine clean ? ( instead of using a full bottle of a certain cleaner , use a fifth to a half of each product depending on the number of cleaners you want to use in order to use about the same amount as a full bottle of a single cleaner )
