Since my car is 19 years old, is 1.100 cc and i drive it about 1.500km per month, i think that is reasonable to check it before every first day's drive.
What's the difference between the ineo mc3 and ineo ecs? As I saw in Total's "lubadvisor", they now recommendation total quartz ineo ecs 5w-30 for my Peugeot 106.
