Will Marvel Mystery Oil - Both Synthetic and Original Help Cold Flow Properties? Supertech 5w30

What about wear protection? Because it thinned the oil out

I use it mostly in my fuel injection. 2007 Ford e-150 4.6 l 309, 000 MI

I’ve never really used MMO much in the oil, I have used it in the fuel. When I watched your videos in the past I started adding it to the oil. My pickup has had a lifter tick for quite some time but it would come and go. So I added MMO according to directions the lifter tick has never come back and runs smoother. I’m sold I will add it at every oil change. The oil pressure has even improved. I haven’t tried MMO synthetic yet but I will be soon. Thank you brother for all you do for us.

I've been using it for over 50 years ..many uses..I love it.

My 2002 Camaro doesn’t use any oil between changes. I have regularly changed the oil at about 3000 miles. Has 240000 miles and still going great. As Rich says, change your oil regularly 😊

[patrickdiehl]

Been waiting for this comparison, I am now thoroughly convinced MMO will be standard on every oil change I do. Thanks Rich, you Rock👊✌️

record lows here this winter. i dumped a qt of old school mmo in the sump of the ole truck. really helps with cold starts when its 10°f

Love MMO. My V10 Excursion started using about a quart of oil every 1200 miles, when it had around 350, 000 miles on it. I added a quart of MMO when it was a quart low and ran it 500 miles, until the oil change was due. I didn’t put MMO back in it at the oil change, but now, it only uses a quart at every 2500 miles and it runs better than it did when it was new. It actually runs like a watch.

Mistake at 1:46 -
20% classic original Marvel Mystery Oil formula
10% synthetic Marvel Mystery Oil formula I said 20 I made a mistake on my way back

You’re videos are I think the best on YouTube and you’re detailed information and professionalism is absolutely amazing.

This is also what has become known as a "Mid-West Oil Change". In areas where it can get bitter cold in winter but also way too hot in the winter, it was customary to change your summer oil right about when winter would start because a lot of rural (and even not rural) truck owners would run a 40 weight in summer because of temperatures that would run 100 F and above for a good portion of the summer and a5W-30 weight oil would just thin out too much and lead to engine noise. But come winter the 10W-40 would just get way too tick for the mid-west winter temps which could drop in to the negative numbers.
The thing is, some of these rural truck owners were primarily using these vehicles as "ranch trucks" and were not putting thousands of miles on them between seasons so there was still plenty of life left in the summer oil so in some cases they were using that for other purposes such as in other miscellaneous equipment rather than letting it go to waste. Story goes (I read this in an auto enthusiast publication, a while back) that a well known old time mechanic, WW2 vet and shop owner had one of his regulars bring his truck in for the seasonal oil change since winter had already begun but the shop was waiting on a delivery of the normal 5W-30 that they use for oil change service.
So the shop owner/mechanic checked how many miles was on the summer oil in the truck had on it and it was only about 1600 miles. So he gave the truck owner a couple of options. One was he would give the truck owner a call when the oil delivery arrive and he could bring his truck back to get the 5W-30 swapped in, or the other option was that because there was still plenty of life left in that oil, he could just add 1.5 quarts of Marvel Mystery Oil to the summer oil (the truck was a 7 quart oil capacity) that's already in the truck. The truck owner had never heard of that second option and so he asked the old timer mechanic why he never mentioned that as an option before and was it really safe to do that.
So the shop owner replied that he had never been out of 5W-30 before and that it would probably be bad for business since the shop was normally swamped every year that time of year by people bringing in their cars to also get their own cars changed over to winter oil but this particular truck owner had been bringing his vehicles to this same shop owner for 20 years so he thought what the heck, he's been a great customer might as well let him know this is an option.
The truck owner still had his doubts if it was safe though, so the shop owner pointed out that his own old Chevy truck which he had owned for several decades now had over 350, 000 miles on it, same engine which was still running fine and he had been doing the MMO "winter oil" trick the entire time he had owned the old truck.
So after seeing it with his own eyes in the shop owners own truck he decided to go ahead and give it a try. so the shop owner added a quart of MMO and sent the truck owner on his way. Several months later, the shop owner got a phone call in the dead of winter. It was the truck owner who decided to go with the MMO treatment rather than wait on the 5W-30 to arrive. He decided to call in and tell the shop owner what had happened. The temperature that morning had dropped to negative 5 degrees F.
When it was this cold out he said normally his truck would crank for about 5 seconds or so before starting up and some times had to give it several attempts to get it to actually fire up, even with the 5W-30 in it. This time it didn't happen that way. At negative 5 degrees F he turned the key and within 2 revolutions not only did the truck fire up, but there also wasn't the usual lifter noise that accompanied this extremely cold starts and the engine also reached normal idle speed much quicker than when it was running 5W-30 under the same conditions even though it still had the 10W-40 summer oil in it!
He was very happy that the old shop owner had told him about this and was very surprised with the actual results, so he wasted no time in telling everyone he knew about it as well and soon enough the "Mid-West Oil Change" became a thing and plenty of people still swear to it to this day, with their own examples of vehicles in the hundreds of thousands of miles doing the same thing.
Even though I've known about this method for a long time, the area of the country where I live now rarely does it get below 30 degrees F in the winter so I had no reason to actually try this method. Until... we recently had a record breaking winter, with a freak weather occurrence taking place that allowed cold, arctic air to dip down from Alaska in to the area where I live which is normally sheltered from such cold temperatures the mid-west U.S. experiences by the Cascade mountain range, but not this time.
We only had about a 2 or 3 day warning it was gonna hit, and I did kind of wonder how my own car would fair being that I had to drive to work daily and my departure time most mornings was around 4:30 to 5 AM, when the daily temperature is at it's lowest point. I wasn't sure what to expect as far as getting my car started in those temperatures and I was a bit worried but I was about to find out.
So over the next few days the temperatures started to plummet. First few nights the lows were getting down to 15 F and my car was starting to crank slow in the morning, and this is on top of the fact that I had fully charged and trickle charged by car battery ahead of time in preparation for the cold snap, so it wasn't a battery issue. It was just down right cold!
Next night it got down to 10 degrees F and not only was there the slow engine crank and a delay before the engine would fire up, but even after it did fire up boy was there a loud hum and vibration like you get while holding an electric toothbrush lol. It was the engine having to put up a fight/protest at trying to circulate that very cold, thick oil (which ironically at the time was SuperTech Full Synthetic 5W-30) and there was also some timing chain rattle at start up to go along with the other protesting.
Well I wasn't happy with that at all, and I started thinking what I could do, then I remembered about the Mid-West Oil Change! I always have MMO on hand since I use it for various needs in the garage so I figured it was not only worth giving it a try, but even more-so, I really wanted to see what it would do for situations of sluggish, slow cranking, noisy cold starts.
I also decided to err on the side of caution though so I started out only adding about 8 ounces on the first morning. Even at that low dose, there was most definitely an improvement in the cold start! That morning it was actually even colder than the previous morning with the low being 8 degrees F, but yet the car didn't protest as much once I added the 8 ounces of MMO to the crankcase.
The next morning was even colder yet, with the temperature dropping down to 5 degrees F, so I decided to go ahead and try adding another 8 ounces of MMO (for a total of 16 ounces now) and the difference was night and day! The car started up as if it was no colder than 30 degrees out, no exaggeration! Timing chain noise diappeared no more loud hum/vibration as I let the car warm up, even though it was now the coldest morning so far at 5 degrees F!
The results with the MMO in those bitter cold temperatures were so good even at just 16 ounces that I just kept it at that and ended up changing that oil out in late February once the cold snap was over, and I mainly changed it out then because it was getting close enough to the normal change out interval and in addition to the MMO working it's winter wonders also did it's usual thing and turned my oil black due to it's cleaning properties (more-so than it would normally be for the amount of miles I had on the oil), so I figured it was a good time to change it out anyhow.
A few things I learned.:
#1) I REALLY don't care for 5 degree winter weather!
#2) SuperTech Full Synthetic seems to get pretty thick when it's that cold out even though it has the 5 Winter rating.
#3) Anything below 15 degrees F will result in slower cranks and a delay in oil getting where it needs to be.
#4) At those temps, engine will protest for a while even after it does fire up which can't be a good thing for engine wear.
#6) MMO took care of all of that and in MY case/situation, it only took 16 ounces.

My conclusion: For whatever small drop in viscosity that resulted in me adding the MMO to the oil, that was far outweighed by the fact that it eliminated the slow cranking/hard starts. timing chain rattle, heavy hum/vibration after starting, all of which means that the oil was now getting to where it needed to be much faster regardless of the extreme cold and that's the whole point!
I really don't know if we'll ever see that severe of a cold-snap again where I live but at least now I know that if we do, since I always keep some MMO on hand, I'll be covered. Don't think I'd do this though with some of the new cars that take these ultra-low viscosity oils like 0W-16 or *gasp* 0W-8 but since they already take oils that are barely thicker than water, they probably wouldn't need any help anyhow.

[blasemessina]

I use that in all my vehicles, and I must say, they run Excellent!!!! I think the detergent properties contained really clean the intake

[erickut]

They don’t even list it on there marvle website the marvle synthetic I was gonna try it But it must of been discontinued Only ultimate and original and the hot rod classic motor oil

[mikefisc]

Relatively new to your channel and this is my first time seeing this video. This is an outstanding video. I'm a seeing is believing guy when it comes to YouTube. I just picked up a bottle of Original MMO yesterday at the auto parts store. I think next time I'm there I will grab a bottle of the synthetic version too. Both will have there place and function in my garage. Thank you for the video.

[FordBossMe]

The reason 20% Marvel Mystery Oil outperforms in the cold flow testing testing compared to the 10% is because there's much more of it that's why but you can see the clear difference when you put it in your oil how it affects the overall cold it just makes it better

synthetic has PAO base which improves oil properties anyway so it would be your better bet for your engine oil but both of them are adequate they work phenomenal

[circuitsoftime]

Marvel Mystery Oil is an outstanding product! I use it religiously in all my motors, big or small, and in my differentials as well! I love their products!

[cfzippo]

Thanks Boss. Always been an MMO fan, nice to see through your videos just why I still am!

[jameskennedy]

Thanks again for doing this. Rich you’re one of the best. I don’t know if you’re the only one who does these test, but you’re the only one that I’ll watch. We don’t have new cars that could benefit from the new Marvel MO, plus our part of Texas isn’t as cold as up north. I’m going to use the standard MMO in our three vehicles. Rich I don’t remember if I told you that our son has a 2003 Suburban with the 5.3L with over 300, 000 miles on it, changed oil & filter every 3, 000 miles. The oil pressure was dropping plus the lifters started getting noisy, he drained the oil put on new oil filter filled the motor with straight GM automatic transmission fluid. Oil pressure went up plus no engine noise. He only drives around town, so far no problems. He done it as an experiment. Rich I don’t expect to make a comment but that’s ok, stay warm

[bobimbordino]

Mmo is still great stuff. I’ll only run mmo in my fuel & now oil. You know how smooth my engine is with mmo in the fuel every 1500 miles.
The tests you do is greatly appreciated by me.
