I did try to search for this topic, but was not able to find one that relates to my situation. I have a few cars and am retired, I don't put many miles on any one car. At most, I post mileage of about 3000 miles per year. At this point I have been changing the oil every year with Amsoil synthetic oils, no matter the mileage (as mentioned, never over 3000 miles). Most of my mileage is highway, probably about 80% highway. The recommended manufacture OCI varies from 6 months to 1 year with a varied range of mileage. I have a couple of questions. If I only drive about 3000 miles a year on a given car is a 1 year OCI okay if the manufacturer suggests 6 months (but at 6000 miles)? There are some vehicles where I drive less than 1000 miles. Is one year still recommended (which I have been doing), or can I extend the time to more than a year on those low mileage cars? Sorry if this topic has been beaten to death, but I have not found one seems similar to my situation.
Thanks,
John
