I went to my local auto store and they had two kinds of MMO, type that does not indicate use for diesel applications and one that said Ultimate.....and had directions on the back for use with Diesel fuel.

Any help would be appreciated.

I checked around the store to make sure that there were no others (types of MMO) and only found one type. It has directions for gas and diesel on the rear. I was confused the first time I went to go and buy this stuff too. I thought I was looking for a lubricant oil... The kind you would use for squeeky doors, bike chains, etc... Because I have a small bottle of MMO lubricant for those applications. However, I did not know there was another variant for automobile applications. I still don't know if they are the same?? The version for auto use seems to be thinner. Anyhow, I bet both types you are looking at are fine.

Wally World Red bottle w/Black label in Gallon jug kind.

Bottle says: Original Formula on front of bottle near pour spout.

Back of jug has MM014 and a BAR Code label # 7787400014

I seem to recall that someone on BITOG did an analysis on MMO and it was said to contain a good bit of Stoddard Solvent in it. Guess that is what helps keep injectors clean.

I also looked up the website listed on the MMO jug: http://www.marvelmysteryoil.com

I'll be darned if I could find ANYTHING about their MMO products other than a press release buried under news. Seems since Turtle Wax bought them they want to use the MMO name to push their wax products and keep the mystery alive.

Here is what I found:

"We developed the One-Shot, pre-measured container, so consumers can easily add it to their gas tank when fueling-up."

Marvel Mystery Oil not only increases gas mileage, it also cleans fuel pumps and injectors, combats internal motor rust and corrosion, lubricates valves, piston rings and upper cylinder walls - all things that prolong the life of a car and increase resale value.

The pre-measured One-Shots come in handy four packs to cover you for a full month and keep your car running at peak performance. With the new One-Shots, Marvel easily becomes part of your pump routine. Each time you fill-up, pour it in and toss it out.

About Marvel Mystery Oil Formerly a product of the Marvel Oil Company, Marvel Mystery Oil was developed in 1923. It gained notoriety for its ability to minimize engine wear and improve gas mileage. Its popularity spread with the Federal exhaust emission regulations and the importance vehicle owners were placing on car maintenance. Acquired by Turtle Wax ® in 1999, the brand continues to be one of the best known names in its field, with its make-up still a "mystery." "
