As the title states I am considering Motul 6100 synergie+ and Repsol Elite Multivalvulas both in 10w40 spec. Car in question is a 1996 Honda Civic 1.4i(d14a3, non vtec sohc 16v - same as any d series but 1396cc), OCI is around 5000km (3000miles), car is driven every day in the city for 2x15mins and taken on spirited drives on most weekends so I would need this oil to be good for both if possible. Other oil recommendations are welcome but I would like to stay with 10w40 vsc. Listed below are the specs of the 2 mentioned oils.
