Exceptional adhesion properties.

AMSOIL MPHD is the product of choice for metal surfaces that require a heavy duty lubricant or are exposed to the damaging effects of salt, moisture or chemical corrosion. It is ideal for hinges, wire ropes and springs, nuts and bolts, motorcycle or bicycle chains, and for undercoating wheel wells and other metal surfaces exposed to water, dirt or road salt.

Recommend for anyone with outdoor equipment such as farms and construction, lawn care and snow removal services, marine equipment, machine shops, and more. Great long lasting indoor/outdoor corrosion inhibitor and is recommended for protecting parts in storage.

MPHD is a heavy duty spray lubricant fortified with special rust and corrosion inhibitors. It prevents and adheres to metal surfaces, leaving a long-lasting protective coating.

  • Does Not Sling Off
  • Does Not Attract Dust
  • Prevents Rust and Corrosion
  • Displaces Water
  • Durable - Long-lasting
  • Eliminates Squeaks
  • Impervious to Water

Excellent penetrating lubricant for:

  • Motorcycle, Bike, Mountain bike, ATV & Conveyor Chains
  • Hinges of All Kinds
  • Wire Rope & Springs
  • Nuts & Bolts
  • Undercoat Car Doors, Wheelwells, Rocker panels, Metal Seams, etc...
  • Metal objects exposed to the damaging effects of water, dirt, or road salt.
  • Amateur Radio Antenna Projects and Outdoor Soldier Joints needing to be sealed.
  • Wonderful for Battery Terminals - Allows for maximum power transfer.

AMSOIL Heavy-Duty Metal Protector is best known for it's ability to protect and maintain lubrication and repel dust and dirt from motorcycle, bike, ATV and conveyor chains.

* You can use our other low cost MP (Metal Protector in the white can) to clean the chain, allow it to dry then apply MPHD. Sometimes break cleaner is needed for stubborn dirt and grime but the AMSOIL MPHD will penetrate all surfaces.

The Original Metal Protector is the better option when you need a lubricant without any film as well as a rust penetrant and to free frozen parts. Also pushes away moisture.

We have sold this to numerous wire-rope manufacturers as a finishing agent to "rust-proof" spools of elevator wire rope. When sold by the drum there is a much higher concentration of solvent which allows the product to penetrate deep within the ropes. Feedback has been remarkable. Orders must be in advance for drums.


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


*Note: Due to the broad use of this product we will be posting some photos and short videos regarding the use of AMSOIL MPHD. One particular application I am rather fond of is the use on front end steering and suspension parts. When restoring or repairing older vehicle front end parts, it's important to seal the elements, salt and moisture away from these expensive and critical parts. After painting and/or primer, apply the Amsoil Heavy Duty Metal Protector. Springs, alignment threads, nuts and bolts and exposed areas in the fenders are prime reasons to try AMSOIL MPHD.

We also see it's a popular product for landscaping tool professionals from numerous posts regarding AMSOIL Metal Protector on the Lawnsite Forum. Prevents grass and debris build-up on mowing decks and other areas where clean-up isn't always convenient. Also allows snowblowers to chuck snow easier without clumping up.

Lately I have received sales for the "Homebrew" Ham Radio market. the AMSOIL Heavy Duty Metal Protector is great for sealing moisture out from fresh antenna projects or modifications. Keeps wire antennas from oxidizing and solder connections from corroding. Stalls the formation of aluminum oxide at adjustable antenna joints. Keeps water out on those remote DX camping sites when operating in field conditions.

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.
Dont forget motorcycle and atv chains, it works super on them as well, and is compatible with o-ring type chains.


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
