What are the differences between Shell Penzzoil and Shell Helix Ultra?
1 Answers
Here are the specific differences between Shell Penzzoil and Shell Helix Ultra: 1. Viscosity grades: Penzzoil has three viscosity grades, which are 5W20, 5W30, and 5W40; while Shell Helix Ultra engine oil only has two grades, 5W30 and 5W40. 2. Performance: Shell Helix Ultra engine oil is made from natural gas, with a purity of up to 99.5%, containing no petroleum impurities, and has a stronger molecular structure, resulting in better performance, such as more stable high-temperature performance, better low-temperature fluidity, lower volatility, and lower friction coefficient. The basic performance of Penzzoil includes exceptional resistance to high temperatures, long-lasting stable viscosity; exceptional resistance to evaporation, reducing oil consumption; and exceptional protection, keeping the engine performing like new. In terms of oil production and technology, Shell Helix Ultra engine oil outperforms Penzzoil in performance.
