* Engine Size: The amount of oil needed varies greatly depending on the engine size in your specific car. The 1999 LHS came with several engine options (2.7L, 3.3L, and 3.5L).
* Oil Type: Different oil types have different viscosity (thickness) and may require different amounts.
* Oil Change Procedure: The exact amount of oil needed to "completely refill" the engine block during an oil change might be less than the full capacity.
What you should do:
1. Check your owner's manual: This is the most reliable source for your vehicle's specific oil capacity.
2. Consult a mechanic: A mechanic can provide you with the correct amount of oil based on your specific engine and oil type.
3. Look for the oil dipstick: The dipstick in your engine will show the correct level of oil.
Important Note: Overfilling your engine with oil can cause serious damage. It's always better to consult a reliable source for the correct amount of oil for your car.
