Car Forum / Honda Cars / February 2006Marvel Mystery Oil
I've heard good things about Marvel Mystery Oil. Just curious how it works since you can put it in the oil and gasoline tanks and does it work well still with newer cars, I have 05 Civic. Also, what's the best time to put it in like early/middle/late life of oil for oil. And for gasoline empty tank then fill, or after full tank? > I've heard good things about Marvel Mystery Oil.

The very best time to put Marvel Mystery Oil in your car is...NEVER. Total waste of money. It will do less for you than timely oil changes.

Just curious how it > > works since you can put it in the oil and gasoline tanks and does it [quoted text clipped - 11 lines] > The Unofficial Honda/Acura FAQ > www.tegger.com/hondafaq/ Back in the day, you could buy a Marvel Mystery Oil reservoir that attached to the carburetor and slowly dripped the stuff into the gas, or so my father told me. I used it 20 years ago as a gas additive in my Chevy small block. As far as I could tell, it did me no good. Not sure I'd want to subject my Honda fuel injectors to this stuff. If you feel the need to add something to your gas add a bottle of Chevron's Techron every now and again. AFAIK that stuff won't hurt anything and probably does some good. I'd never consider adding MMO to my oil because I don't know what it would do to the viscosity or how it would interact with the oil's additives. TeGGeR's right, clean oil is good oil. At least one of the major car companies - DC I think sez in the owners manual that using crank case additives will void the warranty. Back in the days of lose engines - a increase in viscosity may have been a good thing - not today - will probably impede lubrication. Any modern oil that meets all of the current requirements will be fine - just change it and the filter and do it regularly. It never ceases to amaze me when I walk past the snake oil section of auto parts stores - people still buy that stuff. >At least one of the major car companies - DC I think sez in the owners >manual that using crank case additives will void the warranty. Back in >the days of lose engines - a increase in viscosity may have been a good >thing - not today - will probably impede lubrication. Actually, I think MMO would probably decrease the viscosity of the oil, and I wouldn't want to do that either. MMO is an old product. If it had any extraordinary benefits as a crankcase additive, its components would have been incorporated into motor oils long ago. That said, I have seen it recommended for various general and special lubrication purposes. It is probably a very fine light-weight, general purpose lubricating oil, but it is neither marvelous or mysterious. > At least one of the major car companies - DC I think sez in the owners > manual that using crank case additives will void the warranty.

Tolerances on the parts going into engines have gotten much tighter over the years. For some time I worked in a bal bearing factory that made a number of parts for the automotive companies. I can remember them pushing us to have much tighter tolerances on the parts we supplied them. I suspect that's continued over the years as it seems that today's engines are much more efficient than engines from a few decades ago. >>> At least one of the major car companies - DC I think sez in the owners >>> manual that using crank case additives will void the warranty. Back in [quoted text clipped - 5 lines] > I would guess back in 70s and earlier. Tolerances on the parts going > into engines have gotten much tighter over the years. Hmmm... Some examples: 2003 Acura RSX crank journal to bearing clearance: .0007"-.0020" 1991 Honda B18A1 crank journal to bearing clearance: .0009"-.0020" 1975 Toyota 2T-C crank journal to bearing clearance: .0006"-.0039" 1956 Chevrolet six or V8 crank journal to bearing clearance: .0007"-.0028". The tight tolerance is essentially the same from 1956 to 2003, but the older engines were permitted to get a lot looser before being considered out-of-spec. I'd suspect metallurgy is a lot better now, so they can afford to specify tighter tolerances and still get adequate life out of the engine. Also, oils back in 1956 or 1975 were not what they are now. Sort of with poyethylene, back then you had to make it thick to get the film strength. Now they can do it by making the polymer chains longer and stronger. I think that and metallurgy have more to do with the lightness of modern oils than viscosity requirements.

Another couple I just found: 1970 Ford 302 V8 crank journal to bearing clearance: .0005"-.0024" 1970 Ford 250 six crank journal to bearing clearance: .0005"-.0022" I'm not sure those old engines were much looser than modern ones. SignatureTeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ >> 1975 Toyota 2T-C crank journal to bearing clearance: .0006"-.0039" Oops. This is for the smaller 3K engine. the 2T clearances were: .0013"-.0022", only slightly bigger max than the '02 RSX.

Back in [quoted text clipped - 26 lines] > -- > TeGGeR® Informative post TeGGer... As a hobbyist who plays with old Studebakers, I know that all of the factory tolerances were to four decimal points. That said, the engines did not have the long lived characteristics of today's designs probably from the standpoint of lubricants. Certainly, the materials (used by Studebaker) were up to snuff to modern variety and included virtually no plastic. OTOH, some of the seals don't approach the reliability of modern design but a plus is that many components when rebuilt include modern seals. One other consideration is that earlier American engines never had to endure the revs that modern Japanese engines thrive on. RPM's topped out at about 5K unless the engines were modified. Oh, I do own a Honda, a 1983 Civic FE project that is getting close to bearing fruit in the form of gas savings... JT SEAFOAM! or LUCAS OILS FUEL TREATMENT! You can buy them both anywhere. Gas tank only though. I think that the only thing you should add to your oil is oil, and that's just if it's low. Mobil 1 is always my suggestion and change it at 3000 or sooner. As for MMO, I wouldn't want to trust something that is able to be used in the engine and in the fuel. Plus, you have a Honda!!! You don't have to do too much to those things and they'll still run forever, so don't fix what isn't broken. Run good gas, keep up on maintenance, and that's about it. See ya. Matt Signaturemtmaurer8ooo http://www.automotiveforums.com Start saving up money... to buy a new catalytic converter. The whole concept of marvel oil is a little bogus. Gasoline already has a lot of oily components in it, and that is what lubes the upper cylinders well enough for engines to last 300,000+ miles. Now check out Brazil, which insisted on developing ethanol production to replace gasoline use. Result is, engines don't last at all. The alcohol has no lube qualities, and the engine is toast. > Start saving up money... to buy a new catalytic converter. > [quoted text clipped - 5 lines] > to replace gasoline use. Result is, engines don't last at all. The > alcohol has no lube qualities, and the engine is toast. You are full of bovine fecal matter. Gasoline is a SOLVENT, NOT a lubricant. It washes motor oils off the bore walls. Gasoline does have a touch of light machine oil in it, but that's for the injectors, not the bores.

I don't know. Gasoline may not be as good a lubricant as oil but I can see how it would be a lot better than ethanol. Not saying that he's right, but it isn't implausible IMO. Do Brazilian liquor burners really go through engines like a drunken sailor? I hear they are still selling well and by now everyone would know it if they were self destructing. I couldn't find anything on the web about it either. > You are full of bovine fecal matter. Gasoline is a SOLVENT, NOT a > lubricant. It washes motor oils off the bore walls. I specifically said UPPER CYLINDER WALLS. Sure, it would be better to have some 10W30 up there, but it isn't really happening. Solvent, lube, whatever. Don't get hung up on labels. Did you take organic chemistry 30 years ago like I did? There's a lot of oily in gasoline, and it isn't due to any additive. My wife has two relatives doing an extended project in Brazil right now, and they'll agree with me regarding engine longevity.

The only thing I used Marvel Mystery Oil for when I was twisting wrenches for a living, was to put a small amount in the inlets of my air tools, then blowing air through them before putting them away at night... I wouldn't put it inside an engine, not now, with all of the electronics and sensors, for sure... . > I've heard good things about Marvel Mystery Oil.

They still make that -- shades of JC Whitney and the ooo ga horn >> I've heard good things about Marvel Mystery Oil.

SignatureTeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ > They still make that -- shades of JC Whitney.... Hey, don't knock JC Whitney. They've saved my butt more than once. An example was replacing the aluminized batt insulation in a '69 Dodge van engine box (the one between the seats) I once owned. I looked everywhere. Dodge dealers, Autoshops, boat centers, RV centers, custom shops, you name it. After 2 weeks I was at my wits end. My buddy suggested I look in JC Whitney . Sure enough, twice as much as I needed for $30, including shipping. JC Whitney is alright. http://www.jcwhitney.com/autoparts/StoreCatalogDisplay/c-10101/s-10101 nb > I've heard good things about Marvel Mystery Oil. Just curious how it > works since you can put it in the oil and gasoline tanks and does it > work well still with newer cars, I have 05 Civic. dont waste your money. Why does Honda now use 5W-20 oil? It's so obscure and it's difficult to find it in stores. Is it recommended that I switch to Mobil 1 or just stick with Honda Oil? What are the differences? |
