Easier Engine Cold Start

In order to start effectively, engines must reach a critical cranking speed. As temperatures drop, achieving critical cranking speed becomes more of a challenge. Low temperatures cause motor oils to thicken, and if they thicken too much and impose excessive drag on moving parts, critical cranking speed will not be achieved and the engine will fail to start.

Motor oils used in winter climates must maintain a sufficient low cranking viscosity to allow engine turnover at the lowest temperatures. If a motor oil is able to meet the challenge of allowing the engine to turn over, it immediately faces another significant challenge: providing quick, critical lubrication to the engine’s bearings and other moving parts.

Two types of engine pumping failures can result from cold-thickened motor oil: air-binding failure and flow-limited failure. Air-binding failure occurs when the motor oil surrounding the pump inlet screen gets sucked into the pump, but is not replaced by new oil from the sump. The oil pump inlet screen then becomes starved for fluid, and oil pressure becomes erratic as air is entrained and proper oil flow cannot be maintained. Flow-limited failure occurs when the motor oil becomes so thick that it cannot be pumped through the inlet tube and through the narrow passages that deliver the oil to the engine’s moving parts.

All motor oils thicken in cold temperatures, but how much they thicken is significant to the level of protection an engine receives. Pour point tests (ASTM D-97) pinpoint the temperature at which a motor oil thickens to the point where it ceases to flow. Of course, when oil stops flowing altogether, it is useless. For an engine to receive even minimal wear protection from an oil, it is important it has a pour point lower than typical winter temperatures.

Conventional motor oils face significant challenges in low temperatures because they contain paraffinic (wax) materials. As temperatures drop, the wax components crystallize and agglomerate into large structures. Eventually, the motor oil gels, becomes resistant to flow and fails to provide the engine with the lubrication it needs. In order to hinder the development of these wax crystals, conventional motor oils are additized with polymers known as pour point depressants. These pour point depressants prevent wax crystals from agglomerating and can lower the oil’s pour point. In fact, petroleum motor oil without additives typically has a pour point of only around 5°F, but the inclusion of pour point depressants can lower the pour point by approximately 25°.

Synthetic motor oils do not contain the paraffinic material present in conventional motor oils, so they do not require pour point additives. Synthetic motor oils naturally flow at much lower temperatures than conventional oils, maintaining their cold-temperature protection properties over a longer period of time.

Cold weather operation also increases problems associated with condensation. The colder the weather, the longer it takes for the engine to warm to the point where condensation evaporates. During short trips, the engine may not have a chance to evaporate the condensation at all. Eventually, condensation causes acids to form in the oil, causing corrosion.

Rust and corrosion inhibitors serve to neutralize and protect engines against water and acids. These oil-soluble additives have a greater affinity for metal than water, forming a protective film on engine parts. The Total Base Number (TBN) of a motor oil is an indication of how well it combats acids. The higher the TBN number, the greater the degree of protection.

Good synthetic motor oils are formulated with high TBN. In fact, good synthetic motor oils 5W-30, 10W-30 and 0W-30 all have TBN’s over 11, allowing them to effectively fight acid and corrosion for extended drain intervals.

Good Synthetic Motor Oils remain fluid in the coldest operating conditions. Maintaining their fluidity and protecting ability in temperatures as frigid as -60°F, this not only permits easy engine cranking for quick starts, but flows to critical engine components in a quarter of the time that conventional oils take. Considering that up to 60 percent of all engine wear occurs during cold starts, this immediate lubrication is essential to long-term engine life.

Permit Easy Starting
Motor oil must provide easy cold weather start-up. Petroleum oils are refined oils that contain wax, thickening in cold temperatures and causing the oil to lose fluidity and create drag on the engine upon start-up. Enough drag inhibits the engine from reaching the critical cranking speed required for the engine to start.

Good synthetic sotor sils contain no waxes, naturally maintaining their fluidity in extremely low temperatures. Good synthetic motor oils flow quickly and reliably to allow easy starting and immediate lubricating protection.

Industry testing confirms that synthetic diesel oils reduce emissions
New Environmental Protection Agency (EPA) pollution regulations, requiring a 50 percent reduction in diesel emissions, went into effect this past October. Recently, the EPA approved even stricter emission limits set to go into effect in 2007. After-treatment devices for exhaust gases are generally regarded as the solution to meeting the new requirements, but high-performance diesel lubricants are also effective tools in fighting excessive diesel emissions. In fact, recent independent tests con-firm that PAO-based synthetic lubricants can dramatically reduce particulate emissions, while also improving fuel economy.

Two tests conducted by independent laboratories in Europe compared different 5W-30 synthetic PAO based lubricants with a 15W-40 petroleum oil and a 5W-30 VHVI (Group-III) based oil. When compared with the other oils, the synthetic PAO-based diesel oils reduced particulate emissions as much as five-percent from cold start, while improving fuel economy by as much as 1.2 percent, demonstrating that high-quality synthetic diesel oils can play a big role in reducing exhaust emissions in heavy-duty diesel engines. Good synthetic diesel oils incorporate PAO technology and top quality additive packages, dramatically reducing exhaust emissions and improving fuel economy, while providing the ultimate in wear protection for extended drain intervals.


Shawn Prenatt of Kenmore, N.Y.
Prenatt thoroughly researched synthetic oils. After doing his own performance comparison, he chose this oil.

In May 2004, Prenatt purchased a 1997 Pontiac Firebird with 79,000 miles on it. Before switching to this synthetic motor oil, Prenatt had trouble starting the vehicle in fall and winter.

In October 2004, Prenatt used the Engine Flush and then installed this 10W-30, an Oil Filter, Bosch Platinum +4 Spark Plugs and Wires and this companies Engine Coolant.

“After the engine flush, oil change and spark plug upgrade, start-ups during cold weather are easy,” said Prenatt.

Prenatt reports that his Firebird drives more smoothly and has more horsepower than ever before. Prenatt was also impressed with how much cooler the engine runs after switching to these products.


Lyle Reinier, Mesa, AZ
Reinier drives a 2004 Dodge Ram. He uses Synthetic 5W-30 in the engine, Synthetic Universal Automatic Transmission Fluid in the transmission and 80W-140 Long Life Gear Lube.

“This companies products have given this truck life that it was hiding before,” said Reinier. Reinier said the Ram now pulls stronger and runs smoother than it did before. He made the switch to synthetic when the truck hit the 3,000-mile mark. “What comes as a surprise to me is that my Dodge dealer had no problem doing a complete drain and fill with the synthetic oil I brought in,” said Reinier.

Reinier said the dealer removed all the Dodge transmission fluid and refilled the truck with synthetic ATF. “Within a mile or two I could feel the transmission was smoother and showed a difference in how it performed,” said Reinier.


Guy Keast, Rantoul, KS
"I had heard a lot of good things about your synthetic motorcycle oil used in Harley Davidsons, so I decided to try it out in my 2001 Heritage Softail with the Evolution Series Twin Cam Engine. I noticed right away that the top end of the engine quieted down and on the hot days I run 12-15 degrees cooler than all the guys I’m riding with. I don’t sell your oil, but I recommend it after the improvement it made in my Bike."


Ted Pickul, Sarasota, FL
Pickul drives a 1992 Geo Prizm with unusually high miles. As of February 2005 the Prizm had over 362,000 miles on only 15 oil changes and 31 filter changes. Pickul credits synthetic oil products with extending the life of his car’s engine.

Pickul bought the Prizm new in June of 1992 and after 3,000 miles, converted it to 10W-30 Synthetic Motor Oil. Pickul also installed a 2-Stage Air Filter.

“In November 2003 with 329,000 miles on the engine, I drove the car from Sarasota, Fla., to Carbondale, Ill., without stopping,” said Pickul. “The 13-hour trip was a true tribute to the synthetic oilization of this vehicle.”

The Prizm has a 1.6 liter 4 cylinder engine that has had no major problems. The valve cover was removed at 360,000 miles and it was exceptionally clean.


Eric Pool, Kansas City, Mo
Just wanted to drop you a line and let you know that before I changed my oil I checked the average miles per gallon on my wife's Pontiac Montana via the on board computer and she was getting 18.1 miles per gallon. I then changed her oil to your synthetic motor oil and installed the your air filter and just let her continue driving it. I checked it about 3 months later and her average miles per gallon had risen to 21.1. So she gained 3 miles per gallon switching to your products.


Where can I buy AMSOIL oil

All products have been designed and made in the USA since 1972. That means the 25,000 mile oil change has been around for over 30 years with an excellent track record. This manufacturer has quality as a number one priority and develops all of its products to assure value is created for their customers. That’s my kind of company.

Upgrading to a good synthetic motor oil is easy. If you are looking to run your engine cooler, smoother, and for a long time you can order synthetic oil and filters online. I know finding the right oil and filter is for your vehicle is difficult enough at the auto parts store and spending a lot of time searching through a website for your specific parts is probably not very appealing.
