On October 13, 2023, a significant announcement echoed through the automotive world: Signature Series 0W-40 (AZF) received a nod for being the recommended full synthetic engine oil adhering to the Chrysler MS-A0921 specification. For many, this may seem like just another industry-standard announcement. However, diving deep into the implications, it's evident that this validation is a game-changer, especially for high-performance vehicles.

A Fit for the Modern Automotive Giants

The Chrysler MS-A0921 specification isn't just any other standard; it encompasses many of the modern Dodge SRT street-performance giants. Picture the thunderous roar of the Challenger and Charger SRT. These beasts, with their pulsating 6.2L Hellcat engines, represent the pinnacle of road performance, blending both speed and power in a seductive high performance motor package. Moreover, the specification covers the Ram TRX, another titan powered by a 6.2L engine. And for those who appreciate raw strength coupled with durability, the HD models like the 2500 and 3500 series trucks, equipped with the 6.4L Hemi, also fall under this specification. Hence, this oil's compatibility with this specification isn't just a minor industry footnote; it's an affirmation of the oil's quality and adaptability.

A Deeper Look into the AMSOIL Signature Series Motor Oil

This oil is not just another entrant in the vast ocean of motor oils; it’s a distillation of cutting-edge technology and deep-rooted expertise, resulting in a 100% synthetic motor oil designed to meet the demands of today's high-performance engines.

  1. Exceptional Engine Protection: One of the primary concerns of any vehicle owner is engine wear and the loss of horsepower over time. The Signature Series provides a staggering 75% more engine protection against such issues. This isn’t just a number plucked out of thin air; this is based on stringent independent testing of  0W-20, conducted as per ASTM D6891 protocols required by the API SN specification.

  2. Enhanced Cleaning Power: The engine, much like the heart, must remain free of obstructions for optimal performance. Deposits and sludge are adversaries that can hinder performance. Here, this oil shines again with 50% more cleaning potency compared to its OE Motor Oil variant.

  3. Superior Turbocharger Protection: Turbochargers are intricate components that demand exceptional lubrication for sustained performance. This oil doesn’t just meet the industry standards; it transcends them, offering protection to turbochargers that's 72% more efficient than what the GM dexos1 Gen 2 specification requires. This is ascertained by the independent testing of the 5W-30 in the GM turbo coking test.

  4. Acid-Neutralizing Might: Acidity in motor oil can spell disaster for engines, causing corrosion and compromising performance. Once again, it sets itself apart with a remarkable 28% more acid-neutralizing capability compared to Mobil 1. This is not a speculative claim but one rooted in empirical evidence from independent tests comparing Mobil 1 Annual Protection Full Synthetic 5W-30 and AMSOIL Signature Series 5W-30 using the ASTM D2896 methodology.

  5. Trust and Reliability: Words and numbers can convey performance, but trust is earned in the field. This oil has garnered the confidence of professional engine builders, a testament to its impeccable quality and reliability.

  6. Long-Term Protection Guarantee: In today's fast-paced world, frequent maintenance can be a hassle. Recognizing this, the company offers guaranteed protection for a staggering 25,000 miles or a complete year, ensuring peace of mind for users combined with fiscal savings with extended service oil change cycles.


The High-Performance Edge

From the days of the 1967 GT 500 to today's naturally aspirated motors, in high performance vehicles like Hennessy cars, engines aren't just about speed and power, especially those designed for high performance. They represent the pinnacle of engineering, demanding the finest in care and lubrication. With increasing demands on performance, there's a parallel need for motor oils that can withstand the stresses and strains of high-speed operations, rapid acceleration, and constant revving, whether on the race track on during daily driving scenarios.

This oil not only meets these demands but often exceeds them. The aforementioned benefits are not just numbers and claims; they represent tangible benefits for high-performance engines, ensuring that they deliver consistent performance, remain free of deposits, and last longer. The focus on aspects like acid neutralization ensures that the engine remains free of corrosive damage, further enhancing its lifespan. This oil is perfect for your next synthetic motor oil change service, ensuring your high performance engine has the best syn oil to deliver the horsepower your vehicle has under the hood!

In Conclusion

The automotive world is in constant evolution, with cars becoming faster, stronger, and more efficient. This progress demands parallel evolution in ancillary products, especially automotive oil.
