PYB and MMO

I have a slight lower knock in a Acura V6 when idling and thought I would give MMO a try. Will most likely try a pint for my remaining OCI. Thanks guys.

I'd be interested in your results. I don't ever remember using it for a lower end knock. Lifter noises I had great success with.
 
I'll let you know. It has a knock with a cold or warm engine. Otherwise it runs great for a 118K mile engine. I have had other Honda products and never heard a knock before. Thanks.
 
I have 3 cars that have had PYB 5W30 + 1qt MMO for 3 full OCIs now. I am doing 5k OCIs with this combo.

While I have not done any UOAs, All 3 are running smoother and quieter, with maybe a little more power. All 3 saw the oil get dark very quickly on the first OCI, less the next one, and by the 3rd OCI, seemed to darken at a normal rate (or maybe even a little less than normal as it seems it was all cleaned up).

I did look down the fill hole this weekend (again) when I just changed 2 of them out - and they are both spotless, including no varnish at all (I think Varnish is a problem and not just cosmetic - topic for another day).

One of these has 90k miles on it (2003 Expedition with the 5.4) and I witnessed significant cleaning from the first 3 OCIs, via looking in the fill hole and by the fact that the oil filter felt very heavy compared to normal (changed out this time - I only change every 10k) as it seems to have caught quite a bit of junk from the second and third OCI, but I suspect mostly from the second one).

I am very pleased with this combo and will continue with it.
 
Just got done changing the oil in my truck. 5 quarts PYB 5w30 and 1 quart MMO. Been using this combo for about 3 years, but I don't always use the MMO each OCI.

No problems to report. The GM dealership I frequent occasionally claims it is the quietest truck they've ever driven or serviced.

I wouldn't worry too much about the Hondas. They might have thinned the oil down a little too much using the 5w20, but I imagine the climate is a bit colder where you are than where I am.

Tell them next time just run the PYB and their engine will be fine. If they weren't clean before, they will be now that's for sure.

Has anyone on here used the combination of PYB (Pennzoil Yellow Bottle) and MMO (Marvel Mystery Oil) together? If so, do you have any kind of test results, even if only a UOA (Used Oil Analysis)?

Thank you


I've used them together many times for myself and for friends. Sorry I don't have pictures, compression tests, or a UOA. So you'll have to take my word, sorry.

Anyway over 35+ years I have used it, and PYB was my favorite Dino oil, in fact it still is. I have silenced lifters, cleaned engines, and got a lot of buddies of mine using it over the years. These pages are probably scattered with my MMO stories, LOL someone PM'ed me and called me the MMO Czar.

If you are thinking of trying it with PYB, it is a great combo. PM me if you like Johnny and tell me what you are trying to accomplish and I will be happy to give you info and not bore members with it. LOL


You live in the wrong place to be a Czar.

Up to nothing. Upon MY recommendation, a friend at church changed the oil in his wife's 2007 Accord and his 2006 Civic using PYB 5W-20. That's great, no problem. What I did not know is that on another persons recommendation from where he works, he substituted 1-quart of oil for 1-quart of MMO in the Accord, and 1/2-quart of oil for 1/2-quart of MMO in the Civic. Now I have to be politically correct now and bite my tongue, as I do not want to say anything bad about his friend at work, especially since I also know this person and consider him a friend. I am between the rock and the hard place, so to speak. Personally, I did not nor would not recommend this. He will be changing his oil in 5K.

Nothing wrong with either car. Both engines clean and run great. This was not for some kind of fix and was not done just before an oil change, this was done with the oil change for the duration of the oil change. I did just tell him to be sure and check the oil level on a regular basis to be sure it stayed full.


I've used the combination recently (1qt MMO + PYB) but didn't do any UOA testing. Used it on a VERY abused Ford Escort GT with HEAVY sludge (I used a putty knife to scoop out some sludge from the valve cover and top of the cylinder head). The engine had developed a pronounced lifter rap. After idling for 20-30 minutes with this combo, the lifter noise went away. Took the car on a highway drive for a few hours and then dumped the oil/filter and replaced with PYB + 16oz MMO. The stuff that came out looked like the chocolate stuff you'd pour on an ice cream sundae. My friend recently changed the oil again (also black, but no longer the thick goopy mess it was last time) and is now running PP w/out MMO. Valvetrain noise is still gone.

Would I do this to a relatively new/clean engine? No.

If it was my car or my friend, I'd probably tell them to dump it after a couple thousand miles and skip the MMO next time since there isn't really any "problem" to solve here.

Best,
 
I have a few quarts of 15w40 left over from my last motorcycle and I have nothing (vehicle wise) that takes it. I was thinking of using 3.2 qts and 1 qt. MMO to clean up the 'ringpack' of my Saturn 1.9. I would wait until the warmer weather. What would the viscosity of this concoction be and do you guys think this is a good idea?
 
I always top off with MMO near or at the end of the OCI, and then dump the oil for fresh oil without additives...

....all that untill I see clean valves through the oil fill hole...

After that its only oil and nothing else.

Start with little and see how it cleans...
 
May try putting some MMO in my son's 1999 Olds Aurora Northstar(V8). He is within 1K of a change so I will try it. The car has 130K miles and still running smooth.

Give it a try, I use to do the same thing with my old Corolla. About 1-2,000 before an oil change. Did this three times and MMO was cleaning the engine up nicely via the fill hole.

+1 I just had a look at another great UOA with MMO added to the oil. In fact of all the UOA's with the addition of MMO that I have seen they all look good.

Used MMO in Mercedes diesels if I was hearing the "nailing" noise from injectors that were firing off early, below their designed pop-off pressure due to gum or water in a bad batch of fuel. MMO cleaned them up within 50 miles. I'd dump a pint in a 19 gal. tank of diesel and it worked great.

I'm running 25% MMO in a Mercedes ML500, 17% MMO in a Mercury Grand Marquis and 20% MMO in a Mitsubishi Pajero/Montero - all running Fuchs Titan SuperSyn LongLife 5w30 full synthetic. Oil change intervals are 15,000 kilometres/10,000 miles and I have yet to top up in either application.

The other application is 17% MMO in a Chevrolet Avalanche with Motorcraft Synthetic Blend 10W-30, changing oil based on the OLM.

I've also run 20% MMO with Lexus full synthetic 5W-40 in the ES, before I switched it over to Mobil 1 0W-40. I add a pint of MMO 5,000 km/3,000 miles before I'm due for an oil change. The same is true for the Camry, also running M1 0W-40 in the 5S-FE.

I'm not trying to force what I beleive upon others, but MMO has been working well for me. MMO helps keeps the engines clean, and they also tend to perform better...you get that extra 'punch' so to speak. It's cured lifter ticks on my 189,000 mile Mitsubishi truck, whilst all 6 engines are running very quietly with it in the oil. Granted, I also run TC-W3 in the fuel. The only reason I don't run MMO in the fuel is cost - TC-W3 works out cheaper when you have a number of cars you're using it in.

Demarpaint and myself are firm beleivers in MMO, and its worked really well for us. It may not be everyone's cup of tea, but to each their own. I just don't see a reason NOT to use it, seeing it's worked really well for me.
 
I haven't used MMO myself, but I also believe that it does something good, based upon what others say about it.
It is also low priced(almost the same cost as the oil you otherwise would use).
I also can not see so many reasons to not using it.

Sadly, it isn't possible to buy it here, and if I order it on the web, it is some $20 in freight, for a quart.
That's to much.

Nice report Falcon LS, glad to read the MMO is working well for you in several applications. It was your open minded nature that let you try it, and now you're seeing the benefits. As you mentioned in most cases a qt of MMO is actually less than a qt of many of the oils we use. I'm glad to see you tried it instead of bashing it based on what you thought or read.

I've gotten several PM's from people over the last few months who went out and tried MMO and were very pleased with it. Like you said it might not be everyones cup of tea.
