Wondering which engine oil would be best for my Cally, can anyone help?
I´ve had good experience with Mobil 1 10w40 in the past, but for my dear Cally I gave it the fully synthetic Mobil 1 5W50. Nothing but the best for my baby, uuuh yeah
The other day, however I did an, ehm, temporary oil change to 10W40 and I actually noticed that the engine now sounds much better when cold starting. So I´m wondering whether the 5w50 was right to begin with.
Any ideas, guys?
