FYI --- It's COLD Outside!! Protect your Engine!!
Winter Oils -- Pour Point and Cold Cranking Simulator Tests
API Comparative Motor Oil Testing
Amsoil Synthetic 10w-30 Motor Oil (Product Code ATM) and 10 competing conventional and synthetic 10w-30 motor oils were subjected to a series of seven API motor oil tests.
I want to discuss two of these tests --- Pour Point and Cold Crank Simulator Tests --- since it is so darn cold this winter as compared to recent Winters.
The Pour Point Test indicates the lowest temperature at which a fluid will flow. The Cold Cranking Simulator Test (CCS) measures a lubricant's viscosity at low temperatures and high shear rates. The impressive test results show AMSOIL Synthetic 10W-30 Motor Oil outperformed the competitors in each test.
Pour Point (ASTM D-97)
The Pour Point Test determines the lowest temperature at which a lubricant will flow when cooled under prescribed conditions. The lower a lubricant's pour point, the better protection it provides in low temperature service. As shown in the graph, Amsoil Synthetic 10w-30 Motor Oil has the lowest pour point of the tested oils.
The low Pour Point of Amsoil 10w-30 Synthetic Motor Oil allows it to maintain its fluidity in extremely low temperatures, reducing drag on moving vehicle parts, providing critical engine components with quick, essential lubrication and easing startup in cold temperatures. Wear is greatly reduced and equipment life is extended.
Cold Crank Simulator (ASTM D-5293)
The Cold Crank Simulator Test determines the apparent viscosity of lubricants at low temperatures and high shear rates. Viscosity of lubricants under these conditions is directly related to engine cranking and startability. The lower a lubricant's cold crank viscosity, the easier an engine will turn over in cold temperatures. 10W motor oils are tested at -25°C and must have a viscosity below 7000 cP to pass. As shown in the graph, Amsoil Synthetic 10w-30 Motor Oil is well below the maximum requirement, while many of the competing oils barely pass.
The low cold crank viscosity of AMSOIL Synthetic 10W-30 Motor Oil reduces drag on moving engine parts and allows engines to achieve critical cranking speed in extremely frigid temperatures. Engines turn over quickly and dependably in the coldest winter temperatures.
AMSOIL Synthetic 10W-30 Motor Oil provides unsurpassed protection against engine wear. Equipment life is extended, and repairs, downtime and expenses are reduced.
__________________________________________________
Amsoil has been the leader in synthetic motor oil formulationsince its introduction of the world's first API rated synthetic motor oil in 1972. By specializing exclusively in the synthetic lubricant technology, Amsoil is able to optimize the most advanced chemistries available. The "Genuine Synthetic PAO Formulated" designation displayed on AMSOIL packaging indicates that the oils are formulated with Polyalphaolefin (PAO) synthetic base stocks.
__________  __________
This chemistry is the industry's premier base stock technology. Unlike conventional mineral-based chemistries, Amsoil PAO base stocks contain fullysaturated, hydrogenated molecules and are free of wax and other impurities. Combined with an exact balance of premium additives, it delivers superior hot and cold temperature performance, resists oxidation and acid formation and provides long-term wear protection.
Amsoil "General Synthetic PAO Formulated" oils have shattered the parameters of the most rigorous industry testing and set the standard for all other motor oils.

VISCOSITY
VISCOSITY -- in the general term is defined as " a fluids resistance to flow". it's a measure of the internal friction of the fluid or the resistance to the movement of one layer of molecules relative to an adjacent layer.
THE LOWER (SMALLER or FIRST #, as in "10w-_) NUMBER.. is the Cold Cranking measurement, made at low temperatures, using a concentric cylinder viscometer to predict the oils cranking resistance in an engine during cold starting.
The measuring devices, or viscosmeters, most often used are in the form of close-fitting concentric cylinders. The fluid being evaluated is placed between the cylinder walls, the outer cylinder is held stationary and the inner cylinder is rotated. The speed of rotation is measured for a given force to calculate the viscosity, most commonly reported in cp or centipoise units. Also known as Absolute Viscosity.
THE HIGHER (BIGGER or SECOND #, as in "-30") NUMBER...is commonly measured in capilary tubes, in which the time for a fixed volume of fluid to flow through the tube under gravity at operating temp (100c)is measured and reported as cSt or centistokes. This is used most commonly to report the normal operating viscosity of motor oils or the higher number.
" __w- " is a viscosity GRADE, not a viscosity MEASUREMENT.
When testing for cold fluidity, the temperature is lowered approximately 5 degrees centigrade between each test.
The Cold Crank Simulator Apparent Viscosity is tested at:
-20 C for 10w-
-25 C fpr 5w-
-30 C for 0w-
It is my understanding that the oil has to be labelled at the lowest temperature it meets the specifications.
It may not be long before someone comes out with
a " -5w-30 " which would correspond with -35 C.

Steven. Thanks for the good words for everyone. I switched all the ranch trucks and cars at your advise last month to 0W-30 Amsoil. We had sluggish starts in the mornings because it is always neg. F. in the winters here. On the ranch we are always up early to make sure none of the cattle died overnite. Trucks start a lot better and easyer on Amsoil lower visc. and run better too in winter.

NDakota. Let's just say we will never meet for coffee. I am as far northwest of Bismarck as you are southeast of Bismarck.
