How Extreme Heat Affects Engine Performance
How Extreme Heat Impacts Your Engine Performance
Modern engines in passenger cars and light trucks can reach temperatures exceeding 230°F (110°C), especially when under strain from heavy loads during hot summer months. This rise in temperature is compounded by the use of smaller, more powerful engines aimed at meeting stringent fuel efficiency standards without compromising on power.
Turbochargers play a vital role in achieving the delicate balance between fuel economy and power. While they boost performance, they also generate significant heat, which can pose challenges for engine maintenance and longevity if not properly managed.
What is the Impact of Extreme Heat on Engine Performance?
Extreme heat can significantly affect engine performance by accelerating the breakdown of motor oil, leading to the formation of deposits and sludge. This can result in rough idling, misfires, reduced power output, and decreased fuel efficiency. Moreover, high temperatures can impair turbocharger performance, leading to the formation of deposits known as "turbo coking," which can ultimately damage the turbo. To mitigate these effects, it's crucial to use high-quality motor oil like AMSOIL Signature Series Synthetic Motor Oil, which offers superior protection against heat-related damage, ensuring optimal engine performance and longevity.
Key Takeaways:
- Extreme heat can accelerate the breakdown of motor oil, leading to engine deposits and sludge formation.
- Engine performance may suffer from issues such as rough idling, misfires, reduced power, and decreased fuel efficiency due to heat-related damage.
- Turbochargers are particularly vulnerable to heat-induced deposits, known as "turbo coking," which can impair performance and lead to irreversible damage.
- AMSOIL Signature Series Synthetic Motor Oil provides advanced protection against heat-related damage, preserving engine performance and longevity even in extreme conditions.

The Effects of Heat on Engine Functionality
Extreme heat can accelerate the breakdown of motor oil, leading to the formation of deposits and sludge. These deposits can accumulate on intake valves, hindering airflow into the engine and compromising the sealing of the combustion chamber. The consequences can manifest in various ways, including rough idling, misfires, decreased power output, and reduced fuel efficiency.
Moreover, prolonged exposure to high temperatures depletes the oil's additives, altering its chemical composition and diminishing its ability to lubricate, cool, and protect engine components effectively. The formation of sludge presents a particularly concerning issue, as it can obstruct narrow oil passages, impeding the flow of oil to critical parts and causing premature wear and tear. This concern is heightened in engines equipped with variable valve timing (VVT), where sludge buildup can disrupt the functionality of intricate components, resulting in performance degradation.
AMSOIL Signature Series Synthetic Motor Oil: A Solution to Engine Heat Challenges
AMSOIL Signature Series Synthetic Motor Oil is engineered with an advanced formulation that includes 50% more detergents, effectively combating the formation of deposits and promoting optimal oil circulation. The enhanced detergent and dispersant additives ensure that oil passages remain clean, significantly reducing the risk of sludge buildup. Engine failures attributed to sludge accumulation, often stemming from a clogged oil pick-up tube screen, are effectively mitigated with the use of AMSOIL Signature Series.
The efficacy of AMSOIL Signature Series in preventing sludge formation is demonstrated through rigorous testing, such as the Sequence VG Engine Test, which evaluates an oil's ability to resist sludge under challenging conditions. AMSOIL Signature Series consistently outperforms industry standards, providing 90% better protection against sludge accumulation.
Preserving Turbocharger Performance in High Temperatures
Turbochargers, operating at speeds up to 300,000 rpm and subjected to exhaust gases exceeding 1,000°F (538°C), are particularly vulnerable to the effects of extreme heat. The combination of high-speed rotation and intense heat can lead to the formation of deposits on the turbo shaft and bearing, a phenomenon known as "turbo coking." These deposits can impair turbocharger performance and, if left unchecked, result in irreparable damage.
Effective lubrication and cooling of the turbocharger are essential for mitigating the risks associated with extreme heat. AMSOIL Signature Series Synthetic Motor Oil offers superior protection for turbocharged engines, thanks to its premium synthetic base oils and top-tier additives. Independent testing has shown that AMSOIL Signature Series provides 72% better protection against turbo coking compared to industry requirements, as specified by the GM dexos1 Gen 2 standard.
Maximizing Engine Performance and Longevity
In the face of the intense heat generated by modern turbocharged engines, AMSOIL Signature Series Synthetic Motor Oil stands as a reliable solution, offering enhanced resistance to heat and superior performance. By utilizing high-quality base oils and advanced additives, AMSOIL Signature Series ensures optimal engine protection, prolonging the life of vital components and maximizing performance even in the most demanding conditions.
