How many types of Mobil fully synthetic engine oil are there?

[HarmonyDella]

There are three types of Mobil fully synthetic engine oil, specifically 0w40, 5w30, and 5w40. Here is some extended information: 1. Fully synthetic engine oil: Fully synthetic engine oil is produced by chemically decomposing various natural substances and then synthesizing them with other materials. The advantages of fully synthetic engine oil include high cleanliness, strong fluidity, excellent cooling effect, outstanding oxidation resistance, and a longer replacement cycle, typically around 1 year or 10,000 kilometers. Vehicles with turbocharged engines are recommended to use fully synthetic engine oil. 2. Semi-synthetic engine oil: Semi-synthetic engine oil is a blend of synthetic and mineral oil, with a ratio of 4:6 between mineral oil and synthetic oil. The characteristics of semi-synthetic engine oil include the advantages of synthetic oil while being cheaper than fully synthetic oil. However, its performance is weaker than fully synthetic oil in all aspects, only having an advantage in price. The replacement cycle is also slightly shorter than fully synthetic oil, around 7,000-8,000 kilometers or 8 months. Semi-synthetic engine oil is more suitable for naturally aspirated engines.
