Moly Oil -- What Is It and Why Do You Need It?

Moly Oil -- What Is It and Why Do You Need It?

What is Moly oil?

Moly been used in lubricating pastes and greases for decades, but unless you're in the oil industry, you probably don't know what Moly oil is or even what "Moly" stands for.

Consider this to be your crash course in all things Moly …

First things first, "Moly" is short for "Molybdenum Disulfide".  It looks similar to graphite. In fact, Molybdenum all by itself is a very hard metal that has a number of industrial uses.  It's actually used to make steel tougher, so that it won't bend as easily.  With it, manufacturers can use less steel --and, thus, make lighter products -- because it's so much more durable.

In the oil world, though, Molybdenum disulfide is a compound that's used as a dry lubricant.  While the term "dry lubricant" may seem like an oxymoron, that's exactly what Moly is!  Even though it's a solid, it's made up of microscopic particles that are great at coating surfaces.  That coating effect reduces the amount of friction between the two surfaces.  As a result, moving parts can move more easily, without causing nearly as much wear and tear as they would if the Moly wasn't there.

Because it's so good at reducing friction, Moly has become a common additive to oil.  When you hear someone use the term "Moly oil", they're actually talking about oil that has had Moly added to it.  Over the years, Moly oil has become one of the premium types of oil on the market.

Because Moly's friction-reducing capabilities are a very big deal!  It's easy to underestimate how bad friction can actually be, so let's look at from your engine's perspective…

In order for you to drive across town to work, all of the metal parts in your engine have to work together.  Without oil, all of those pistons, rods, cylinders, and valves would be rubbing up against each other.  That metal-on-metal contact puts a lot of stress and strain on the parts themselves.  After all, it's harder for them to move around when they've got all of that friction.  Unfortunately, the harder it is for the parts of your engine to move around, the more fuel they're going to eat up.

Even the most basic of motor oil will reduce the friction in between all of these moving parts.  But when you add Moly into the mix, the friction is reduced dramatically.  Remember, the Moly coats each tiny piece of equipment underneath your hood.  As a result, you wind up with Moly-on-Moly contact, instead of metal-on-metal.

You can probably figure out where we're going with this.

Thanks to the Moly, all of the parts inside your engine will be able to move with less stress and strain. That means they won't require as much fuel.  Just like that, you've given your car's fuel efficiency a serious boost!

But we're not done just yet.

Having a car that eats up less gas is great, but Moly oil actually takes things even further.  In addition to giving you more fuel efficiency, it also cuts down on the wear and tear inside your engine -- meaning you could have fewer breakdowns and fewer expensive repair bills.

But Moly oil will give those parts even more protection.  Remember, Moly oil has tiny particles of Molybdenum in it, so it's going to look different than average motor oil.  That added difference will shield the parts of your engine even more, which will make them last considerably longer.  Moly oil will also help eliminate some of those strange sounds that are coming from underneath your hood -- like ticking or knocking -- because virtually all of those noises are a result of metal-on-metal contact.  They're your car's way of screaming for help!

Best of all, Moly is tough enough to withstand high temperatures and high-pressure situations.  So, whether you're taking a quick trip to the grocery store or embarking on a cross-country road trip, your Moly oil will be up to the challenge.

When you look at it that way, the best way to sum everything up is, "Holy moly!  That's some kind of oil!"

Can a moly oil be improved?

The answer is yes.  And Schaeffer's has done just that by adding Penetro, their own secret ingredient.  What is Penetro and why is it such a great thing?  Penetro is really a marvel and breakthrough in oil additives.  Try and think of Moly as a very slick and strong surface protector and Penetro as tiny tiny ball bearings dispersed precisely throughout the oil so that friction is reduced so much so you can actually feel it in the pedal.  Yes, you heard me right you can really feel it.  So now the cat is out of the bag and now you know why so many racers secretly use Schaeffer's oil.
