You cannot pour the same amount of oil into a four-cylinder engine as you can into a V8, and doing so would compromise the entire lubrication system. Ignoring these distinctions when shopping for oil at an auto parts store leads to guesswork.
How Much Oil a High Mileage Engine Really Needs
First, consult your vehicle’s owner manual, which lists the exact capacity and the recommended oil weight (viscosity). Insufficient lubrication leads to increased friction, overheating, and rapid engine wear, potentially causing catastrophic failure within minutes of driving.
When you change the filter, you are removing that stored oil from the equation. Variations Between Vehicle Types Beyond the basic four-cylinder versus V8 distinction, the type of vehicle plays a huge role in the math.
How Much Oil a High Mileage Engine Requires for an Oil Change
Therefore, the total amount of oil you need to add back is the sum of the oil capacity of the engine minus what remains in the old filter, plus the full capacity of the new filter. On the other hand, overfilling the crankcase creates excessive pressure and can cause the oil to foam.
