This blog post compares Mobil 1 Advanced and Pennzoil Platinum Ultra motor oils based on lab results from a 2006 Lincoln Town Car. The analysis reveals that Pennzoil Platinum Ultra outperforms Mobil 1 in terms of wear metals, oil viscosity, and overall engine performance, suggesting it may be a better choice for extended oil change intervals.
In this article, we will delve into a detailed comparison between two popular motor oils: Mobil 1 Advanced and Pennzoil Platinum Ultra. This analysis is based on lab results from a 2006 Lincoln Town Car, focusing on performance metrics after specific oil change intervals.
The testing involved running Mobil 1 Advanced 20,000-mile formula for 3,000 miles and Pennzoil Platinum Ultra for 5,000 miles. The decision to run Mobil 1 for a shorter interval was influenced by increased engine noise at startup, which prompted a closer examination of the oil's performance, especially when paired with a K&N air filter known for its performance but potentially higher dirt ingestion.
The lab results indicated significant differences in wear metals between the two oils:
Viscosity is crucial for engine performance, and the results showed:
The TBN is an important measure of the oil's remaining additive package:
While both oils maintained a healthy TBN, the Pennzoil's performance over a longer interval suggests it could be run longer without compromising engine protection.
Based on the lab results, Pennzoil Platinum Ultra outperformed Mobil 1 Advanced in several key areas, including lower wear metal levels, better viscosity retention, and a more favorable TBN after extended use. The findings suggest that Pennzoil Platinum Ultra may be a more effective choice for those looking to maximize engine protection and performance over longer oil change intervals.
The author expressed a preference for Pennzoil Platinum Ultra, citing not only the lab results but also a noticeable improvement in engine sound and fuel mileage. The cost-effectiveness of Pennzoil, priced at approximately $27.99, further supports its value compared to Mobil 1.
Following this comparison, the author plans to test AMSOIL 5W30 and Royal Purple oils to continue exploring the best options for engine protection and performance. Stay tuned for further results and insights in upcoming articles.
