Remove the dipstick by pulling it up. Note the minimum and maximum marks before you reinsert the dipstick back into the engine block.
Use a clean cloth to wipe off any oil that may still be on the dipstick. Note the hatched part of the dipstick. MIN level is at the bottom of the hatched. MAX level is at the top of the hatched part. The oil level needs to be between the MIN and MAX.
Insert the dipstick into the same tube to check the engine oil level on your Chevrolet. The level needs to be between the min and max mark we saw earlier. If the engine oil level is below the min mark, you need to add engine oil to your vehicle. Follow instructions as described in the next step. If the level is significantly above the FULL mark, you need to remove oil from the engine. If the engine oil level is below the MIN mark, continue to the next step.
Locate the oil filler cap and determine the recommended engine oil grade. For example, 5W-20. Unscrew the cap by turning it counter-clockwise. The cap may be tight.
Add the recommended grade engine oil. Add only half a quart at a time and check the level consistently. If the oil level is still under the MIN mark, add more engine oil. Add 0.5-1 qt of oil at a time and recheck the oil level.
Don't overfill the engine with oil above the MAX or FULL mark on the dipstick. Overfilling the engine with oil can cause engine problems or damage the Chevrolet catalytic converter(s).
