BLUF: Wait two hours before checking your M88-series vehicle’s engine oil to prevent a potentially dangerous situation.
Mechanics, don’t get into too big of a hurry to check your M88-series vehicle’s engine oil level.
Always wait at least two (2) hours after shutting down the engine to check the engine oil level. That allows enough time for all the oil to drain back into the engine.
If you check the oil too soon, you might get a reading indicating more oil is needed when that isn’t the case. And if you add too much oil to your vehicle’s engine, trouble is bound to happen that can lead to flames shooting out the right exhaust stack.
So be patient when checking the oil. And one more thing, make sure your vehicle is parked on a level surface before checking the oil to get an accurate reading.
