Similarly one may ask, will 5w20 instead of 5w30 hurt my engine? In general, it is not recommended that you use 5w30 oil (or any other oil weight) in place of 5w20 oil, as the slightest difference in viscosity can potentially damage your engine.

Besides above, will the wrong oil damage my engine? Cause damage to engine life

The wrong engine oil can cause engine damage because it does not properly lubricate its components. This will lead to metal-on-metal contact since the moving parts are not being lubricated. Friction quickly follows, causing engine parts to wear.

Likewise, what happens if you put the wrong engine oil in your car? Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.
