Today, new cars sit on the dealer lot with build dates of summer 2015. Got mine in an early summer clearance; only had 30 miles at time of sale with a build date of August 2015. The dealer stated it uses synthetic oil and is good for about 7500 miles/1 year (June 2017), whichever comes first.
But does the oil filter break down, even if not driven much that year on the sales lot? The filter would be in place almost two years from its installation (August 2015) to first oil/filter change (June 2017).
The oil filter isn’t expensive, and I change the oil & filter myself. I’m asking because I wouldn’t want to replace an otherwise good filter now if it can wait until next summer. (Car is owned, not leased; so I want it to last as long as possible).
