Will thicker oil reduce engine noise?
When you have low oil volume or low oil pressure, you'll commonly hear a “clattering noise” coming from the engine's valves. ... Adding more oil will make the noise go away, but it won't solve the underlying cause of the noisy engine – the oil leak.
What happens if engine oil is too thick?
If the oil is too thick (aka, the viscosity is high), your car may not start in cold temperatures (cold weather places more strain on a vehicle in any case). When this happens, the thick liquid can't properly lubricate every part, and it creates enough resistance to impair the most important function–ignition.
