Is Fuchs PT7 Engine Oil Fully Synthetic?
2 Answers
Fuchs PT7 engine oil is not fully synthetic. Below is relevant information about synthetic oil: 1. Introduction to synthetic oil: Synthetic oil is derived from ethylene and propylene dispersed from natural gas or gas in crude oil, which then undergoes complex chemical reactions (Fischer-Tropsch synthesis technology, i.e., GTL technology) to refine into large-molecule base oil. 2. Advantages of synthetic oil: Synthetic oil has a higher viscosity index, so it has better viscosity-temperature characteristics, providing more sufficient lubrication at high temperatures and better fluidity at low temperatures (appearing thinner than mineral oil of the same grade at room temperature). Engine oil blended with synthetic oil has stronger oxidation resistance, significantly extending the oil change interval. Although the investment in oil increases, the number of oil and filter changes is reduced.
I previously researched Volkswagen's motor oil product line, and the PT7 series is indeed a full synthetic oil. This series utilizes advanced synthetic base oils and additive formulations, providing superior anti-wear performance and high-temperature stability. Particularly the PT7 5W-40 variant, it excels in low-temperature fluidity, offering excellent cold-start protection. The biggest advantage of full synthetic oil is its extended oil change interval, lasting about 3,000 to 4,000 kilometers longer than mineral oil. However, it's important to note that some car owners might mistake the semi-synthetic PT5 for the PT7. Additionally, I've found that this type of oil is especially suitable for German turbocharged vehicles, as it effectively reduces engine noise in practice.
