Hi, stumbled across this video and have seen many like it. What is the general census on using this flush or other products to make our engines last long?

People seem to love the stuff. Thoughts?

snake oil is snake oil.

and jeep 4 liters have one thing in common with our engines, they have 6 cylinders in a row.

use quality oil, change it regularly, maintain your shit, and it will last a long time.

edit:
quick google
naptha, just like every other flush or additive that claims to clean a motor.
it's cheaper to just buy camp fuel buy the quart.
that's what the farmer's used to use.

There are very few additive products that actually do something helpful. Motor Medic is not one of them.

Nice. Why not? And which ones actually do something helpful?

unless you have very specific reasons to attempt to desludge a motor, you don't need oil additives.

They are most always napthalene based. It's pouring lighter fluid into the crankcase.
If you think it's a good idea, go buy a quart of lighter fluid for way less money and measure out 6 oz of it and pour it into the motor. That's what you're doing.

I see. Thanks for the info. I have been reading about many peoples successes and wanted to see what this forum thought about its use in our engines. Wherever I look I see people swearing by the stuff.

none of the cleaners will work on a N54 because fuel does not
pass over the intake valves. Also true of any direct Injected Car.
Techron would be about the only thing I would use you get it
in Chevron gas anyway.
There may be unintended side effects from all this stuff.

I remember slick 50 .

Use it only if it makes you feel better. Otherwise, it's a waste of money.

I had a bottle of Marvel Mystery Oil that I bought a few years ago to add to my motorcycle fuel tank when I wasn't riding it for a few months. My N52 was a quart low, and I was soon due for an oil change, so I figured I'd experiment and mix up a quart of new engine oil with this MMO at the recommended ratio just to see what it looks like. I wasn't trying to do an engine flush, I just wanted to see what fresh oil mixed with it looked like. Other than coloring it red, it didn't make any noticeable change to the viscosity. I poured it in my car and drove a week before I did an oil change. Again, I wasn't trying to use it like a flush, I just wanted to mix it to see what it looked like.

I know Marvel Mystery Oil isn't as strong as some of these dedicated engine flush products, however I just can't see how any of these magic cleaning products can be effective at the diluted concentrations at which they're used.

I wouldn't do anything that would loosen any gunk in the engine and have the potential to clog oil passages.

If your engine is dirty, do some short interval changes with LL-01 synthetic oil.

Like stated above the 4.0 Jeep engine is quite a different beast, I've owned a few of them. They can get build up inside from going too long on oil changes, overheating, etc.

The only "cleaning" oil I've found to be effective is Marvel Mystery Oil to help free a stuck lifter in a gunked up Jeep 4.0. Then again taking it on a long highway run and keeping the RPM above 3,000 will do the same. This stuff is really useful at getting stuck pistons free in antique farm tractor engines, and that's about it.

I was told by a Euro mechanic that you don't need to flush your motor unless you need to, same thing goes with a transmission.

I opened my S50 with 242k miles on it. Thanks to regular fluid changes the drivetrain and crank we're pristine. I just had to repair the hydraulic lifters but no snake oil is gonna resolve that.

marvel is basically virgin mineral oil with some solvent in it.

look up "stoddard" solvent IIRC. That's what it it.

If u REALLY have to do a motor flush just for the hell of it I would recommend the LIQUI MOLY motor flush. Its the only stuff I would trust as it is gasket neutral so it would not damage the engine's gaskets especially in an old car.

I was reading up on N54 engine and came across this product called Rislone.

Seems that reviews are consistently positive. It may be worth looking into.

Are you experiencing some kind of adverse symptoms you’re trying to cure?

Folks, as it was pointed out, you do not need to flush your engines if your use the full synthetic oil and change the oil when recommended. I just did my value cover after 168K miles and I changed my oil once a year between 12K and 15K miles and I never seen a top end of an engine so clean. Back in the day I have rebuild a number of engines that had around 100K miles and use regular motor oil and if you did not change the oil often enough you would get lots of sludge build up. I can tell you it take more then some additive to oil to clear off the sludge, it take a strong degreaser and lots of elbow grease to get the sludge removed.

I never understood what these additives did other than reduce the viscosity of the oil which is a bad thing.

Just standard noisy lifters.

Unless you've gone 30,000 miles between oil changes for the life of the engine, I can't see any benefit of using an engine flush.

Got it thank you!
