Ok guys sorry I am not a mechanic and i like driving cars based on instinct. Now Fiat says 5w40 C3 style must be used for refilling the oil.
I am looking around online and i am seeing 5w30 being more common or even 0w30.
When will we know that the manual saying 5w40 will be outdated with the continuous advance of motor engine oil technology? And of course when the warranty is over, what oil will we know is best for the engine given that when they built the engine the oil tech was older?
I know some of you will say only stick to the manual and never deviate but some out of the box thinking perhaps anyone?
In a basic 5 year old answer, whats the difference of different oils?
Thank you for helping and sorry if these questions sound ignorant to the techs on the forum.
