This number indicates that the oil behaves like a 5-weight oil when the engine is cold, allowing it to pump easily through the galleries and provide instant protection upon startup, even in freezing conditions. These formulations are designed to improve fuel economy and meet the specific friction characteristics required by the transmission system.

Synthetic oil, on the other hand, is engineered to withstand thermal breakdown and oxidation. This low-viscosity oil flows quickly at cold start-up, protecting the engine during the most critical phase of operation.
Overfilling the crankcase can lead to increased pressure within the valley, causing seals to fail and oil to leak into the combustion chamber. Using an incorrect additive package can lead to transmission shudder or premature wear on the pulleys and belts.

API Service Standards and Additives Beyond the viscosity, the chemical composition of the oil must meet specific performance standards to ensure compatibility with the emissions controls and precision components of the TSX. It also meets the friction modifier requirements of the continuously variable transmission (CVT), which relies on the precise chemistry of the fluid to function smoothly without slipping.
