Since I live in the north of Spain with temps ranging between 68-90 degrees, it's true that
oil could not reach service temp? Engine is a Ford Racing 302-345 bhp. I'm really tied up with
oil choice:
a/ I dont know which
oil is into factory 302 and if I must to use the same or is only for first mileage
b/ Sinthetic or mineral oil?
c/ Lighter oil (if oil cooler mounted) for allow to reach service temp?
d/ Since nowadays oil's degradation is very low (my BMW recomends substitution every 18750 miles) dou you think is necessary to replace it every 3K miles in daily use?
Thanks
Alfonso
