Extreme Heat can effect your engine protection

Today’s cars and trucks have more performance per engine displacement than ever before. Many engines are turbo charged, super charged and direct injected. With that in mind engine operating temperatures are also elevated in some cases over 235 degree. And on days like today July 28th, 2015 with outdoor air temperatures soaring into the triple digits in many place your need for engine oil protection is even greater.
This is even more important for people with trucks that tow heavy loads with boats, campers or trailers or families that take vacations during the summer with a car load of people and luggage. The more an engine has to work, the higher the internal temperatures the engine will see.

Time and time again, using AMSOIL synthetic motor oil can help keep engines running cooler, while give your engine the maximum performance available

Deposits & Sludge

Heat can quickly break down motor oil, creating deposits on the intake valves, which impede airflow into the engine and contribute to poor sealing of the combustion chamber. This can lead to rough idle, misfire
and reduced power and fuel economy.
Extreme heat depletes an oil’s additives sooner, altering its chemistry and preventing it from lubricating,
cooling and protecting as designed. Sludge can form, which clogs narrow oil passages and prevents oil from reaching vital components, causing wear. Preventing sludge is particularly important in engines that use variable valve timing (VVT). Intricate parts sensitive to sludge can fail to operate properly, resulting in reduced performance.
Testing done by an independent, third-party lab demonstrates AMSOIL Signature Series 5W-30 Synthetic Motor Oil’s (ASL) superior extreme-heat resistance compared to a leading conventional oil. Signature Series’ superior heat resistance resulted in 81 percent fewer deposits (5 times cleaner) than
the conventional oil. Motor oil can thicken (viscosity increase) over time in service, leading to sludge formation. Thicker oil is more difficult to circulate, reducing fuel economy, while sludge can clog oil filters, oil passageways and the oil pick-up tube screen, leading to pump starvation and catastrophic engine failure.

Oil Consumption

When oil volatilizes, the lighter molecules evaporate, leaving behind the heavier components. This leads to viscosity increase, which makes the oil more difficult to circulate and reduces fuel efficiency. You
may have experienced this when your car “uses” oil and requires frequent top-offs. Volatilization also creates emissions that contribute to air pollution. If enough motor oil is consumed, eventually there may not be enough to reach all the complex parts of the engine, which can potentially cause damage.
Signature Series Synthetic Motor Oil demonstrated 38 percent less consumption than the conventional oil, reducing frequent top-offs. The Double-Length Sequence IIIG Engine Test Study (G3320) offers additional proof of performance. After 200 hours, Signature Series scored 86 percent better for piston deposits compared to industry standards for 100 hours, easily passing the test Signature Series’ high-performance additives and quality base oils offer improved resistance to heat, maximizing the performance and life of your engine and keeping it clean.

Sequence IIIG Engine Test

The Sequence IIIG Engine Test is designed to evaluate automotive engine oils for high-temperature
performance, including oil thickening, piston deposits, oil consumption and engine wear during moderately high-speed, high-temperature service. Download the AMSOIL Sequence IIIG Study Now.
 

Conclusion:

AMSOIL Signature Series motor oils and in particular the 5W-30 Synthetic Motor Oil (Product Code ASL) met API SN/ILSAC GF-5 performance requirements despite the severe nature of the double-length Sequence IIIG Engine Test. Values for piston deposits, hot-stuck rings, cam-plus-lifter wear and viscosity increase remained well within the requirements after 100 hours of testing. Even after doubling the test interval to 200 hours, the oil easily met all requirements and delivered excellent performance. Results demonstrate that Signature Series provides outstanding engine protection and cleanliness in today’s hot-running, sophisticated engine
In cases of high temperature operation and high heat: Motor oil can thicken (viscosity increase) over time in service, leading to sludge formation. Thicker oil is more difficult to circulate, reducing fuel economy, while sludge can clog oil filters, oil passageways and the oil pick-up tube screen, leading to pump starvation and catastrophic engine failure. A viscosity increase of 50-60 percent is considered very good after 100 hours of Sequence IIIG Engine Testing. Signature Series showed only a 27.6 percent viscosity increase after 100 hours. Even after doubling the test interval, viscosity increase (41.5 percent) remained well below the threshold. Signature Series demonstrated outstanding oxidative stability.
For a better understand of how well AMSOIL will protect engines. Download the AMSOIL Las Vegas Taxi Cab Field Study. Las Vegas has some of the highest temperatures in the country. On top of that, many taxis spend a considerable amount of time idling (with the a/c going) as well as much stop and go driving. These taxis are tough on engine oil.
