The Spray Lubricant without the mess! No Oily build-up!

Best lubricant spray in the world for motorcycle clutch and brake cables. Instantly lubricates and runs down the line. Seems to take 5 to 10 pounds of effort off the effort! Also saved my remote mirors on the old AMC Eagle.

AMSOIL MP is the product of choice for drying electrical and ignition systems and protecting electrical equipment from freshwater and saltwater damage. AMSOIL MP is also the product of choice for protecting firearms and other fine componentry.
It contains no silicone. AMSOIL MP is compatible with plastic, leather, fabric, fishing line and paint.

Let AMSOIL's Metal Protector become your most depended on lubricant in your household. One of the properties making this spray lubricant unique is that it doesn't leave a wet oily varnish over time like WD-40. That's why it's also a favorite with firearm owners because it doesn't interfere with the action of the weapon and cause dust and bits from the holster to attach.

Here are some common uses:

  • Cuts through rust and frees frozen components
  • Prevents rust and corrosion, even in salt water
  • Displaces water
  • Stops squeaks
  • Clean—Leaves no film & will not gum up
  • Sprays into hard-to-reach places
  • Protects electrical equipment
  • Ideal for firearms and other fine componentry

AMSOIL Metal Protector is best known for it's ability to free up neglected parts. But it's multipurpose keeps customers coming back. Here are some testimonials and other practal uses for the Metal Protector (product code AMP).


Spray product on area to be treated. For best results, do not wipe off. Film carrier will evaporate, leaving MP on treated surface.

AMC Forum - "I had some remote mirror controls on a car totally frozen. I was told I would need to replace the cables but just a shot of Amsoil Metal Protector made the units pivot like new again. Now when I'm driving the mirrors easily adjust as needed!"

From Firearm Forum - "I use it on all firearms. I have used it on my black powder firearms and like it.It cleans fast and when the firearm is clean it gets a quick spray to prevent rust. Loosens percussion nipples easily.
I never used it on firearms until a customer told me that was what he bought it for. I am picky on what I use to clean and use as a rust preventative.It has a much higher amount of lubricant than other brands that I have heard of. And has not harmed the wood."

Ford Focus Forum - "Amsoil makes a penetrating spray called MP (metal protector). It works better than ANY penetrating lubricant I've ever tried. As a mechanic. I've used everything. WD-40, PB blaster, Corrosion-X, Murphy's, etc. When our amsoil dealer brought over some cans of their "MP" we tried it out. Time and time again, it has busted loose bolts, cleaned corrosion off electrical contacts, and lubed sliders like no other product."

"Another great one is MP-HD (heavy duty) This comes in a black can and I've had AMAZING success with it. Its a dry lube and we use it exclusively for lock cylinders. 5 out of 5 times, the MPHD has freed frozen lock cylinders in under an hour. most of the time in less than a minute. When we first got the can from our dealer, we had a back door lock that had been frozen for weeks. We were going to call the landlord and have the lock changed but our dealer suggested we try the spray. We sprayed some in and at first nothing. I checked every so often and it was still stuck. About an hour later, I tried it again and it worked! the lock turned freely and smoothly. We have been using the lock ever since and never had it so much as stick."

"Four cars have since come in with frozen ignition cylinders. every single one freed up in under a minute after spraying the lock with the MP HD. 2 of them got replaced at the owners request but 2 of them decided to chance it. To this day, those locks are still turning freely, thanks to MPHD."

Dodge Diesel Forum - "AMSOIL MP is one of the most versatile products in the AMSOIL product line."

The Tractor Forum - Amsoil Metal protector (MP) has a multitude of uses, I personally use it on my guns as a protector to prevent rust, I also found that when deer or pheasant hunting when temps go below zero MP will not get thick and gummy like Remlube and many of the other gun oils will, thus eliminating misfires caused by an action that will not cycle properly.
It also works excellent as a penetrant and as a metal protector to prevent corrosion, I use it to prevent rust on occasional use tools that get put away and not thought about again until needed.
Another thing I use it for is key locks on vehicles and exterior doors, it displaces moisture and keeps them from freezing up when it gets cold.
Another product you mentioned is Heavy Duty Metal Protector ( MPHD)
MPHD is an awesome chain lube, I have many area farmers using this product on planter chains and corn and bean head chains.
MPHD comes in an aerosol can and sprays out as a liquid that penetrates into the pins and bushings of the chain, once applied the solvents evaporate and it leaves behind a dry waxy film that lubricates beautifully, but does not attract dust.
Most chain lubes stay wet after application, wet chains attract dust to them, the dust mixes with the chain lube and makes a gritty lapping compound that ends up increasing the wear and reducing the life of the pins and bushings in the chain.
The farmers I have using MPHD swear by it, most are reporting 2 to 3 times longer chain life on planter and cornhead chains versus the wet type chain lubes they were previously using.
Another place I use MPHD is on battery terminals, because the waxy residue it leaves seals out oxygen which eliminates corrosion.
Once I have cleaned the terminals I give them a coat and let it set until the solvents evaporate, I repeat this until I have 2 or 3 coats on the terminals.
Don't forget motorcycle and atv chains, it works super on them as well, and is compatible with o-ring type chains.

*Note: Due to the broad use of this product we will be posting some photos and short videos regarding the use of AMSOIL MP. One use I would like to present are on old knobs and controls where occasional use would definitely cause stress and breakage. With Amsoil MP you loosen old grease and dust which has created a mess. Items such as air conditioner control rods, radio tuning dials, hard to reach actions in staple guns or nail guns.
Even tools which get left out in a wet tool box - use AMSOIL MP to remove the moisture instantly.


New entry level synthetic for an easy decision for everyone.Have you NOT tried AMSOIL in your passenger car but would like a low cost high performance warranty compliment synthetic to change at OEM intervals or less? Would you prefer to buy from a true American Company totally focused on quality control and also supports small business and not overseas ventures?
The new AMSOIL OE (Original Equipment) is for you:

More than 1/2 of our customers come to AMSOIL for products other than our passenger car motor oil products. The two main reasons:

#1. I wasn't familiar with that line - We learned about AMSOIL's via motorcycle owners or through the use of the heavy duty industrial products.

#2. I use AMSOIL in my work vehicles but for the family car, I don't drive that many miles and just get it changed at 3000 to 5000 mile intervals. As your motor oils cost more and last 25,000 miles, I feel I'd be wasting the extra life still in them.. I just can't get past the 5000 mile interval.

The new "LOW COST" AMSOIL OE was designed for our customers who buy AMSOIL products for their "other than passenger car" applications such as motorcycles, diesel trucks, power equipment, farm and work fleet.

Well here it is - the oil which outperforms the on the shelf synthetics yet cost the same or less delivered. The OE API Certified line is only slightly more expensive than most quality petroleum motor oil products. Call and see for yourself.
Now you now have no excuse not to use AMSOIL in all your vehicles. If you came to AMSOIL for a special air filter, you can now purchase oil for only a slight change in shipping. Available in popular 5W20, 5W30 and 10W30 viscosities.

Give us a call and see what a case will cost you! It's much less than the Mobil 1 in the stores. 800-579-0580
