What's that? You know, I really love this stuff right here. Marvel's mystery oil. Yeah, I literally use this in everything. It goes in your gas, it goes in your oil, and I'm not really sure what it does. All I know is it does something. So usually, yeah, I put this stuff in the gas more or less than anything. And it only tells you to use about two bounces. So you go from one line about halfway down to the other. So you don't use that much of this stuff when you put it in the gas. And it's supposed to help increase gas mileage, make the engine run smoother, prevent the plug harboring buildup, and keep the upper cylinders lubricated, and all kinds of great stuff that you get from this. I'm like, wow, why did they use so little? If this stuff is so good, why don't you use a whole cord and gas tank? And I'm like, well, if two ounces is good, then a cord must be better. And if a cord is better, then a whole gallon must be best. So I'm going to go ahead and throw a whole gallon of Marvel's mystery oil in the tank of my new 2020 Mustang here. We're going to see how it does. We'll see how well it helps the car. Hopefully. And you know what they say? You can never have too much of a good thing, right? So in goes. Good to the last drop. And I think that is all of it right there. Whole gallon in the gas tank. All right. So we got the whole gallon in the gas tank. I just want to make sure that everything is nice and mixed. So I'm going to go down the street to the gas station. I'm going to top it off with some fresh gas. Mix everything up nice. I'm going to go for a drive. And then maybe we can witness the miracle of the mystery oil. So let's go ahead and get to the gas station. All right. Just pulled up here to the gas station. So we'll go ahead and top this baby off some fresh 93. So we got the car topped off fresh gas. So now we'll go ahead and drive around and see the magic of the Marvel's mystery oil happen in real time. So let's go ahead and drive around and see what happens. So far so good. The car is running pretty good. Running no more different than it usually does actually feel almost feels like it's maybe a tad bit smoother. It can be a placebo effect but could be the magic of the Marvel's mystery oil. So just gotta keep driving see what happens. I don't know that. I felt nice. Well I mean I know the car is running fine. Power seems to be just as normal as running maybe tad bit smoother just maybe. New problem so far. So I mean yeah suppose it's helping out with engine operation and advocating the cylinders that great Marvel's mystery magic baby. But another thing it's supposed to do is help the fuel economy you know a little bit supposed to help and you know keep fuel economy at its max while I'm thinking while it's a little bit helps keep it at its max then a whole gallon should give me more fuel economy right. I mean it's got to it's a whole gallon of the stuff. I'll go ahead and I'm going to perform a fuel economy test. I'm going to do a normal just mix driving route like I normally do the car usually averages 24 25 with a lot of stopping to traffic mix driving and I'm going to see if we can get any better than that. So I'm going to go ahead and start driving. I'll update the video after I put a good amount of miles on the car with the mystery oil and tank and see what we get. Alright so after my mix driving I've concluded that there's no difference in fuel economy I'll go ahead and show you. The magic of the mystery oil did not help with my fuel economy so much for that. I was really hoping that one maybe have some change but it didn't but shortly a gallon of mystery oil has got to help something. I mean especially in the combustion chambers so I want to pop out of spark plug and I'm going to take a look at everything and see how things looking there. See if it looks any cleaner any better and see if it's helping inside of the combustion chambers. So let me go ahead pop the hood take spark plug out and we'll go and check and see what's going on. I'm not going to get too crazy with this. I'm just going to pull out cylinder one spark plug and we'll take a look at it. See how it looks. Alright so I mean if you can see there is actually looks like a lot more carbon deposits being built up on the spark plug there so that's a little weird especially right there around the electrode. See that? Interesting. It does have kind of a reddish tint very interesting otherwise spark plug looks just fine. It has that smell that scent of the Marvel's mystery oil. That's great. Alright so there you have it. Pretty much you're wondering the whole video what was going to happen when I put that much mystery oil in the gas well turns out nothing happens. In fact even though it doesn't stay on the bottle now they used to tell you right on the bottle that the overuse of the product will not harm the engine but you also won't gain any further benefits by doing so. But since I've taken that off the bottle it's perhaps still says it on the website somewhere but that is true. The car so runs fine there is no adverse effects for running that much more of this mystery oil in the gas maybe just a little extra carbon build up in the combustion chambers but that's it. Cars running good and honestly maybe just a little bit smoother than it was before I did it so I mean I guess that's good right. Anyway that's going to be it for this video if you like the video please give it a thumbs up show everyone you know from one to see more content like this and you have them ready go ahead subscribe to channel and keep looking out for next true car enthusiast video.
