For the last three years I have chged my mother's oil in her '98 Ford Taurus (or '99?) on my July trip to Oklahoma City. I assured her that she would be fine on this one OCI per year given her 8 to 10k mileage. I know zip about Fords (I do know hers is the low performance version of the engine (under 100k miles on engine - 15 mile trip average)). I have always used M1 10w30 (used EP last year) w/ M1 & Pure1 filters. I have kept my fingers crossed that all is well (never done an OCI).
Any concerns here given the age of the engine? (she bought it about 30k ago, have no idea of previous maint.) Is M1 EP 10w30 a good choice for this engine at 1 yr OCI?
