Ahoy; Do any of you guys make maintenance decisions based on other factors besides cost-benefit analysis? For instance, my CRV's oil filter is a complete PITA to change...so I'm choosing a 6 month M1 OCI with 12 month filter interval (max allowed by manual). Even though the oil would be good for more than 6 months, and I'll have to opt for a more expensive filter, it's worth it to me to drain early to keep on a 1 year cycle for the filter. Ideally I'd do a 10K/1yr interval and change the M1 and filter together, but I do too many short trips to be comfortable with that. My point is that optimizing the filter interval is my goal because I hate changing it.
