Choise engine oil for 308QV
i write from france, so please excuse my bad english
but i'm going to try to explain clearly my interrogation.
i have an 308 GTSQV 1984 since one month, and my question is:
Ferrari suggest to use AGIP SINT2000 SAE 10W50 for this car but i can't found this oil in france!! the last owner of my car use AGIP 10W40 and actually i drive with this oil..
But is it the best choice of substitution or is it better to use 5W50 as i ear??
so 10w40 or 5w50 ???? may i have to change or can i continue with this oil (10w40)
thank for your answer
