7-7.5k OCIs, on mineral oils, is why many vehicles have issues.
Start a more frequent OCI, depending on oil used, and you'll have less future problems.
10w40 might be a little thick for Utica winters.
IMO, without a used oil analysis, a mineral oil used for 5k OCI's might not be up to the task, especially since you don't "put a lot of miles on the Galant". I would think that 'timely' and not 'mileage' based intervals would be better.
