Hi all. I've been having problems with a rough Idle, and dropping revs for a few weeks now. I took the car in to a shop to see what they thought (yeah I know, bad move), anyways, they recommended doing a TKO (can't remember what it stands for, but I think something along the lines of Total Kop Out, would be close), it's something about cleaning the injection system. Of course it did not help any, but I did notice that the car would now stumble under acceleration (oh joy ). I thought that maybe one of my Cats had become clogged. Anyways, I've been reading how alot of people seem to put MMO into their systems (for various reasons), so I thought I would as well. I put in a whole bottle ( about a quart), then filled up with gas.
Amazingly, the car does not stumble anymore . I just drove it for 20 minutes, and it was smooth as silk (except at 3800, but as we all know, that's another story ).
Is this just a complete coincidence, or is this stuff really magical?

 

No, it isnt coincidence. It's funny that you posted this because i did the exact same thing today. My car wasnt having any problems or anything, I just wanted to try the stuff out to see if i noticed a difference. Well, I put about 3/4 of the bottle in my oil, and the rest in my gas tank. I went to start the car up, and it stumbled a little bit, But i just held my foot on the gas and let her warm up. After about 10 minutes i went for a spin, and let me tell you i noticed a difference. The car never had a totally smooth idle, and I always watched the RPM needle move up and down while sitting still. Not any more, it was steady as a rock. the engine felt so smooth, accelerated like it was brand new. I don't know what it is with that stuff, but im convinced that it can work miracles. My car felt like it had all the power that it had missed out on, and my engine was like a glove, just unbelievable. I told my roomate right afterwards, he drives an 89 full size Bronco that drives like ****. He went down and got some and poured it into that V8 and the thing ran beautifully. Marvel MYstery Oil is an amazing product.
