Marvel mystery oil gas 2g turbo

[Murdertalon]

I decid3d what the hell I have bad carbon deposits on my 2g pistons and by now likely valves too, I did a head about two years ago and noticed pretty bad deposits on the pistons.

This winter I was forced to drive the 2g as a daily and due to other car issues it is currently a dd again. It started smoking off and on during harsh winter driving. Seemed to kinda go away for a while now it's back.

Today after 2 months of dd and getting fed up with the amount of smoke rolling I decided to put 4oz of mmo and 5 gallons of 91 in and see what she does. So far idle is better, doesn't seem to affect anything negatively and smoking decreased.

Either the smoke is turbo seal blow by, valve guides, or worn piston rings. I have another turbo that's going on eventually but I'm waiting to do link, injectors and turbo at the same time.

Anyone else have anything good or bad to say about mmo? I know it can slightly effect octane rating but mmo is designed to burn CLEAN and help remove deposits. It was origionally designed to be used as supercharger oil and can burn along side fuel without issues. I'm still stock ecu, turbo and injectors so octane rating is much less likely to bother my engine vs a high hp tuned car.

MMO has been a stand by for me in times of dire need. I haven't resorted to it unless intensively necessary, but it's always proved versatile and capable. Its not snake oil or a cure-all, but it has its place.

I haven't left it out of my repertoire of things to use in necessary situations, but don't expect miraculous fixes with it for the long term.

From the way back file.........We used to fill a pop bottle with water and pour it slowly down the throats of carburetors will keeping the motor running, steam cleaning the valves and piston tops, much like a blown head gasket will do. Now with fuel injection, it is harder to do that but I have done it after finding a vacuum hose and let a motor suck the water out of a can/bottle/whatever and keep gunning the engine to keep it from hydro-locking. When we are done, there is ALWAYS a big black sooty spot on the ground where the exhaust dumps. I worked for a retired Marine and he was a mechanic while in the Marines, very meticulous mechanic. I learned sooo much from him (1978-1980). He would also use things like MMO and introduce it in the same manner but at the end, he would flood the motor out with the fluid and then let it set for about 20 minutes. He then would fire up the car and gun the hell out of the motor to clean out the soaking deposits. It would SMOKE like a chimney until it was all cleared out but then would purr like a kitten. Now days, that MAY screw up a O2 sensor but the water doesn't unless it coats the sensor with a bunch of crap. Never had it happen to me but be aware on newer cars. Carbureted motors, I would do this to anytime. Usually we would do this BEFORE a tune up/plug change. Sounds crazy but works great.
Just wanted to throw that out there as an alternate way of cleaning deposits. It sounds like it is working its way thru your fuel system well since you are reporting good results.

I've used MMO for years. It works great as a fuel additive, corrosion & deposit inhibitor, & remover; better than almost all the others. If used properly you're not using enough to effect octane. It only take a couple oz. for a tank of fuel when used for prevention purposes. Helps a whole lot with ethanol fuels. It very versatile stuff & can be used many ways.

It was originally designed to be used as supercharger oil

This is not really correct. Although now owned by Turtle Wax, this is the history & origins of MMO.
"Founded in 1923 by Burt Pierce, the brand has remained legendary for over 90 years. Pierce’s reputation for ingenuity preceded him as he was already well-known for inventing the Marvel Carburetor, standard equipment on 80% of all vehicles produced after World War I. Vehicles of the post WWI era encountered carburetor problems, the most perplexing being clogged jets due to high lead content and other contaminants found in the gasoline of the time. The problem motivated Pierce to direct his creative ingenuity towards formulating a blend of chemicals and petroleum products to clean and maintain clogged jets. He was successful beyond his wildest expectations and the legend of MMO was born."

If you want to remove carbon, something that REALLY works is a product from Yamaha called "Ring Free", it is not cheap but it works like a charm and can even remove deposits on parts that are out of the engine on the bench.

Been running it in gas and a little in oil (going to change soon) and I haven't noticed any negative side effects, which is great. The main positives are that the engine starts slightly easier and idles more steady.

I know it's not going to fix my oil burning issues, I'm hoping it's mostly turbo seals. Maybe it will knock down some carbon.

Last night I pulled my Camber kit because I raised my coil overs back up and found a rear bearing is smoked bad so it's not driving at the moment. Again.. :/
