While the oil is draining, remove the old oil filter using the appropriate filter wrench, being prepared for some spillage. Synthetic blends and full synthetics are engineered to maintain a stable viscosity index (VI) across a wide temperature range.
Changing Synthetic Oil Step By Step Guide
Standard petroleum-based oil contains a complex mixture of hydrocarbons with varying molecular sizes, which leads to inconsistencies in lubrication. Wait a few moments for the new oil to circulate, then check underneath the vehicle and around the oil filter for any signs of leakage.
Replace the filler cap and start the engine, allowing it to run for a minute before turning it off. Allow the oil to drain completely until the flow stops, which may take several minutes.
Changing Synthetic Oil Step by Step Guide
Screw the new filter onto the engine by hand, tightening it securely—usually about three-quarters of a turn past hand tight—to ensure a proper seal without overtightening. If everything appears dry and secure, use the dipstick to check the oil level, adding small increments until the level sits within the recommended "safe" range marked on the dipstick.
