I do mine about every 15k. We had a 96 accord though that had close to 300k on it that I only did at 100k intervals if that. Those were bullet proof though. Id be hesitant to put in redline synthetic but I admittedly know nothing about it. I swapped a transmission in a 2007 accord about a year ago. Took me about 20 hours spread out over a month. After that work I err on the side of caution perhaps analness. The Honda DW1 which is all you can buy now for ATF for a honda is synthetic the older Honda Z-1 is not. I have read though some folks swear by the redline synthetic. You probably would be better served by adding a better transmission filter to the car they sell some aftermarket ones that are pretty good search for magnefine (http://magnefinefilters.com/) on ebay that is what I have on both our hondas.
Honda has had recalls on transmissions but there are thousands of folks who have gotten 200-300k out of them with little maintenance you always read about the bad not the good. At some point they will fail just like a clutch will need rebuilding.
Our Pilot called for the old Z1 with a first change at 90 and then every 60. At the time I got it (used) I did a lot of research and many BITOG users reported having better success with Redline D4 (I dont know if DW1 was out yet). Redline tells me D4 is compatible with Honda fluid. the tyranny holds 12qt but a drain fill only changes half. So rather than wait for 90 to do a full flush I did the first drain fill at 60 and then a drain fill every 30 after that. Figure Im changing half the fluid more often so it averages out. And less danger of causing problems that flushing an old auto can do. and much easier to do.
I like redline oils. I also had an Acura manual box with sticky second gear synchros. Redline MTL fixed that like magic
My truck OTOH will get Toyota WS and nothing else. Nobody, not even the BITOG guys knows if there is any synthetic compatible with it. They say lifetime fill... I'm thinking a change every 30-60
My factory manual still calls out 3000 mile oil changes, for towing use profile, which is what I do. Wife's last three cars have all been spec'd at 10k changes on full synthetic, but always needed topping off at 5k, lest a low oil level sensor light comes on and scares the hell out of you.
Dino fluid is cheap, engines are spendy.
I agree oil changes are cheap vs engine changes. What I think is funny is techs who try to sell you a 3k change on a car for which the manual says 15k. Ive learned a lot reading stuff in BITOG (http://www.bobistheoilguy.com/motor-oil-101/) . I thought I even saw some article about more recent research actually finding some benefits from longer change intervals....
The Pilot oil life monitor always comes on around 6k... Tacoma still says 5k in the book. So I do 5k on both of them. synthetic.
My MIL civic says 15k but she drives so little miles I change hers once a year based on time. then you have big commercial diesels with ridiculous intervals like 50k. its all over the map.
