I guess that could be considered inexpensive therapy if it makes you feel better. It is pretty excessive since oil will normally retain its lubricating properties for over 15K miles and it would take unusual circumstances to contaminate the oil that quickly.

As long as the oil is recycled there is minimal environmental impact, so the only real negatives are cost, the time it takes, and the wear and tear on the drain bolt. The odds are slim that improved engine life or performance will be seen (compared to the normal maintenance schedule) but no one can say for sure without a real study.

 

In all my street vehicles I change the oil every 5000 miles. Unless it is being stored then I change it every six months. But the ATV gets changed once a year. In the racecar I change it once a year or whenever I blow the motor up But the racecar only gets run like 5 or six weekends in a year.

 

I've always changed my oil at 3,000 miles in all my cars.

 

Every 3750 miles.

I have a '93 Accord with 114,000 miles that runs as good as the day I bought it. I always bring it to a Honda dealer (whose service department I trust) for scheduled maintenance (which includes an oil change) every 7500 miles. Half-way though each 7500 mile interval (3750 miles) I get just an oil change.

This has worked well for me with my Accord (I have never been towed or needed any emergency repair) and I have continued this same routine with my S2000.

I also change the oil in my '86 Toyota Celica (172,000 miles and still driven daily) every 3750 miles and have done so since it was new. This car never has had any scheduled maintenance besides oil changes and I only get any other work done on it, when it stops running completely (now about twice a year).

 

Oil is the cheapest protection that you can buy for a car. I may be obsessive, but I change mine about every 1000 miles. Even with Mobil 1 that is not much cash. I know I can sleep better at night.

 

Every 6 months or 7500 miles (whichever comes first) works for me -- just like the owner's manual says!!

 

You're fortunate that you meet the regular use maintenence schedule. For someone who meets the criteria, I'd do that too. But for the others, remember to read the way Honda defines regular use- most short commuters,or those who drive on frequent short trips, anyone who drives in dust, temp extremes, etc. needs to use the other schedule. Many drivers don't meet the recs for the regular schedule.

After break-in, religiously every 2500 miles. . .I even use Mobil 1 tri-synthetic formula. The oil comes out of the engine like it went in.
