As long as I have owned cars I have been diligent about checking my oil. My first car was an RX7 so it was a necessity. I know that every vehicle has an optimum procedure for checking the levels and getting the correct reading. However the information in the owner's manual for the CT4 has me a bit confused about how to check the level.
"Follow these guidelines: . To get an accurate reading, park the vehicle on level ground. Check the engine oil level after the engine has been off for at least two hours. Checking the engine oil level on steep grades or too soon after engine shutoff can result in incorrect readings. Accuracy improves when checking a cold engine prior to starting. Remove the dipstick and check the level. . If unable to wait two hours, the engine must be off for at least 15 minutes if the engine is warm, or at least 30 minutes if the engine is not warm. Pull out the dipstick, wipe it with a clean paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level."
It's the last statement "must be off for at least 15 minutes if the engine is warm, or at least 30 minutes if the engine is not warm." I assume this is based on the first instructions that the best readings are gotten when the oil is cold and drained to where it settled. But then the statement above seems like it would be reversed. It would seem like one would need to wait LONGER if the engine is warm (come up to operating temp I assume) vs when it is still cold unless there is evidence that it takes the cooler oil longer to settle to readable levels. It's just strange. Thoughts....?
