That's the most common approach at least I'm too am following. With just 3,000 miles per year and given you
drive your car up to full operating temp every time it likely doesn't matter that much though. I'd even consider
going two year OCIs.
My summer car is a 1993 5.0 Mustang LX coupe. Owned it for 16yrs. Mobil 1 10W-30 Full Synth+Mobil 1 EP filter since I've owned it. Currently sitting at 123,000km's. April.1-->Nov.1 it usually sees ~2000km's.
My routine has been to drop the oil and change the filter in the spring when I pull it out of storage, drive it for a season, put it away, and do the same the following year. So, 2yrs and 4000'ish km's on it before I do it again.
No short trips, oil always up to operating temp, fairweather driving only, stored at 8-10C during the winter, 20-30C spring and summer. Runs like a Georgia peach never any problems, drains nice and clean, sees the hot side of the tach often.
I've lurked on here for a while before joining yesterday and appreciate all the info I've gleaned from the experts on this board. I understand most of you can't get behind leaving oil in the crankcase for 2yrs but it's solely my opinion that today's synthetics are up to the task.
I felt guilty the first time I changed it after just one season and 2-3000km's, it looked new so that was the first and only time I did that. Been doing two years between changes ever since and all is well.
Great forums here thanks for all the great info. Was refreshing to find out that what I thought was an over the top obsession towards engine maintenance was a mere drop in the bucket compared to some of you brilliant nerds on here
