Hey Scotty,
I have a 2010 Cadillac DTS with 25,000 miles - yes 25K miles. I change the oil every 2 yrs or 2000 miles. Since it's 13 years old now, should I do other maintenance items like change coolant, transmission fluid, brake fluid, etc. or should I just keep on going with what's in it. It is carport kept, not garage. I live in NC so temps vary and only a few days below freezing each winter. All the fluids still look good, but I know looks don't mean a lot.
Thanks for your help.
Joe
If this was my personal car I would change oil every 12 months no more then that. I would then follow manufacturer recommend fluid changes for the rest. But I would consider using a fuel stabilizer and water remover. You biggest enemy is water and ethanol damage to fuel system. There are a lot of additives for show cars and storage that would be beneficial.
