You could check your fluid levels to see that they are properly topped up. Having low motor oil and other essential fluids might be causing unnecessary friction on piston heads.

A loose or slipping belt on the idler pulley might also be the reason. You can check for any major movement on the pulley wheels or squeaks coming from the belt to verify this.

Worst case scenario might be an engine problem such as losing compression in a cylinder, a damaged head gasket, or worn crankshaft.
