Hi everyone!
I need to know that if its fine to switch from zic(x5-20w50) to shell helix 20w-50 or not? Reason for switching is that i can't afford zic after driving every 3k kilometers. My main concern is to know if it will harm engine or not?or its fine to switch the brand that is a bit cheaper and gives more range with same oil grade? Please pin your valuable comments.
Thank you.
