Is Pilot 8000 a Fully Synthetic Engine Oil?

[SanNicole]

Pilot 8000 is not a fully synthetic engine oil; Pilot 800 is a semi-synthetic oil, while the 9000 series and above are fully synthetic. Differences in base oils: Semi-synthetic oils use Group III base oils, whereas fully synthetic oils are a blend of Group III, IV, and V base oils. Replacement intervals vary: Semi-synthetic oil should be changed every 7,500 kilometers or every six months. Fully synthetic oil should be changed every 10,000 kilometers or annually. Different vehicle suitability: Semi-synthetic oil is suitable for economy cars, while synthetic oil is better suited for high-end vehicles with higher performance requirements. Additive differences: Fully synthetic oils have higher TBN (Total Base Number) additive content, resulting in longer oil life and better engine cleaning. Semi-synthetic oils have lower TBN content, shorter maintenance intervals, and are more prone to forming sulfate ash.
