Routine Maintenance
How often should the oil be changed on cars that are driven very infrequently? They are in the garage which never gets below 53 degrees and in very dry. I try to start and warm up or drive them every 6 or 8 weeks in the winter when we happen to get dry streets.What about trans and differential lube? How often should it be changed , miles vs. time? What about coolant? Cars are driven May thru Sept occasionally. I have been changing the oil twice yearly (1 car only gets 100 or 200 miles on it). The other 2 about 1000+. Thanks, Jim
