How Does Extreme Cold Affect Lubricants?

Watch the video to see what happens when AMSOIL Signature Series Synthetic Motor Oil and a conventional oil are cooled to -40º. While the conventional oil fails to flow from the beaker, Signature Series remains fluid and delivers 36% easier and faster cold starts*. This means it can reach vital components faster, providing more immediate engine protection and reduced wear.



As the video shows, extreme cold can cause conventional lubricants to thicken, starving vital moving parts of lubrication. In many cases, thick motor oil will prevent vehicles from starting. Cold, thick transmission fluid results in delayed or sluggish shifts and inadequate protection for bearings, valves and other parts. Thick gear lube, meanwhile, requires more energy to turn the gears, reducing fuel efficiency. Because gears and bearings in the axle housing are splash-lubricated, conventional gear lubes that are too thick at cold temperatures can starve internal components of lubrication, which can cause excessive wear and premature failure.

Conventional petroleum lubricants thicken because they often contain paraffins (wax). While modern refining techniques remove most of the wax from petroleum oil, some wax-like molecules remain. These wax-like molecules are soluble at ambient temperatures above freezing, but crystallize into a honeycomb-like structure at lower temperatures and cause circulation problems. At startup, this can leave working parts unprotected while the lubricant warms to a temperature that allows it to flow.

AMSOIL synthetic lubricants, in contrast, don’t contain waxes, meaning they remain fluid in sub-zero cold. They deliver maximum wear protection for your vehicles, even in severe cold weather.
Firearm Lubricant and Cleaner

The moving parts on firearms (actions, bolts, hinges) must be cleaned and lubricated to ensure top performance and long life. AMSOIL Synthetic Firearm Lubricant presents a premium upgrade over all-in-one products, which sacrifice performance in atleast one area in the name of convenience.
Diesel All-In-One  
Product Code: ADBPCN-EA
AMSOIL Diesel All-In-One (ADB) combines the superior detergency and improved lubricity of AMSOIL Diesel Injector Clean, the excellent cold-flow and anti-gelling properties of AMSOIL Diesel Cold Flow and the increased horsepower and cetane of AMSOIL Cetane Boost in one convenient package. It is safe for use in all diesel fuels, including biodiesel.
Diesel Cold Flow   
Product Code: ADDCN-EA
AMSOIL Diesel Cold Flow (ADD) combats diesel fuel gelling by improving diesel cold-flow ability. It is formulated with an advanced deicer to enhance fuel flow and help prevent fuel filter plugging in cold temperatures. New formula treats double the fuel.
Diesel Recovery   
Product Code: DRCQT-EA
AMSOIL Diesel Recovery (DRC) is an emergency diesel fuel treatment that dissolves the wax crystals that form when diesel fuel has surpassed its cloud point. Diesel Recovery liquefies gelled diesel fuel and thaws frozen fuel filters, avoiding costly towing charges and getting diesels back on the road. For preventative maintenance, use Diesel Cold Flow (ADD) or Diesel All-In-One (ADB).
Diesel Injector Clean
Product Code: ADFPCN-EA
AMSOIL Diesel Injector Clean (ADF/ADFP) removes performance-robbing deposits from diesel fuel injectors to help restore horsepower and improve fuel economy. It is formulated for all types of diesel engines, including high-pressure common-rail designs.
Diesel Cetane Boost 
Product Code: ACBCN-EA
AMSOIL Diesel Cetane Boost (ACB) raises the cetane number of diesel fuel up to seven points for maximum horsepower, increased fuel economy and easier starts in all diesel engines.
Signature Series Max-Duty Synthetic Diesel Oil 0W-40  
Product Code: DZFQT-EA
Protect your investment in diesel power and confidently extend drain intervals with our top-grade synthetic diesel oil. AMSOIL Signature Series Max-Duty Synthetic Diesel Oil delivers 4X better cold-temperature performance when compared to SAE 15W-40 oil in ASTM D5293 cold cranking viscosity test. Advanced synthetic technology provides excellent viscosity control and outstanding extreme-temperature performance, while minimizing oil consumption. The result: protection that’s boosted to the max.

Low Toxicity Antifreeze and Engine Coolant
Product Code: ANT1G-EA
AMSOIL Propylene Glycol Antifreeze & Coolant (ANT) is formulated to provide benefits beyond those provided by today's conventional antifreeze and coolant products. Unlike conventional ethylene glycol-based products, which are acutely toxic, AMSOIL Propylene Glycol Antifreeze & Coolant is biodegradable and its low toxicity limits the threat to children and animals. Its unique formulation provides maximum cooling system protection in extreme temperatures and operating conditions.
Passenger Car & Light Truck Antifreeze & Coolant
Product Code: ANTPC1G-EA
AMSOIL Passenger Car/Light Truck Antifreeze & Coolant provides superior heat transfer and excellent protection against corrosion, freezing and boilover. It provides maximum protection in extreme temperatures and operating conditions, and provides superior protection for aluminum, steel, cast iron, copper, brass and solder alloys.
Heavy-Duty Antifreeze & Coolant
Product Code: ANTHD1G-EA
AMSOIL Heavy-Duty Antifreeze & Coolant provides superior heat transfer and excellent protection against corrosion, cylinder-liner cavitation, freezing and boilover. It provides maximum protection in extreme temperatures and operating conditions, and provides superior protection for aluminum, steel, cast iron, copper, brass and solder alloys.
Dominator® Coolant Boost
Product Code: RDCBCN-EA
Formulated with proprietary tiered surfactant technology, providing quick and effective heat transfer inside radiator and cylinder heads, which results in reduced operating temperatures, more efficient operation, increased horsepower and significantly reduced engine warm-up times in cold weather.
Antifreeze Test Strips
Product Code: G1165-EA
Available in packs of 6 or 70. Use PACKAGE SIZE drop down to select quantity. AMSOIL antifreeze test strips have two different pads on them and test ALL coolant colors. The lowest reports the freezing and boiling (under pressure) protection level. The upper pad reports the pH level and shows a pass/fail area. No other testing is recommended or required. The test strips are the only way a mixture of ethylene glycol and propylene glycol can be checked for freeze protection.
