We have these extended protection oils, Castrol Edge 10,000 miles VS Castrol Edge Extended Performance 20,000 Miles.
Mobil 1 10,000 VS Mobil 1 Extended Performance 20,000
What do they do to make the oil extended performance ? Is it the base stock or extra additives ?
If i'm doing 5,000 mile changes is there any advantage to using the Extended 20K version ?
Thanks
