If you like your car (any car) and want it to remain in good condition, I would never follow any such rediculously long oil change interval even with synthetic oil. Plus synthetic oil or not, the type of filter used is just as important to how long the oil stays good. My rule?: IF your driving is: 1) mostly highway 2) few very short trips 3) not hilly 4) not too hot summer 5) not too cold winter 6) not a dusty environment,
THEN I would use good synthetic oil like Mobile 1 or AMSoil, and a good filter (mobile 1, Purolator Pure-One, AMSoil) every 5000 to 6000 miles.
 
If you said NO to at least two of the conditions above (like me), then I would stick to the usual 3000 mile interval, of course still using quality synthetic oil and a good filter.
 
If you continue to use conventional oil, I would never pass 3 months or 3000 miles whichever comes first, no matter what the conditions.
 
Anyone with the initiative can perform their own test.... change your oil and filter and check it, paying particular attention to the color and odor. Using a clean white napkin to wipe off the dipstick is a good way. Then repeat checking the color and odor weekly until the oil begins to get dark, and/or starts smelling like varnish. That is when you should change it, and the number of miles you have on it at that time should be your interval.
 
Using less expensive oil and fram filters, mine was getting bad at way less than 3000 miles. I now use only Mobile 1 Extended performance oil and Pure One filters, and I could go to maybe 3500 or 4000 miles, but I don't. 3000 is my limit.

I don't think you can't tell anything about engine oil by looking at it.
 
The Dark Oil Myth
 
Are oil changes every 3,000 miles really needed?
 
I use dead dino in my minivan and have pushed the usual recommended 7,500 interval out to 11,000 miles at least once. It's a '99 and ~133,000 miles on it. Oil's a lot better than it used to be.
 
If you really want to know what shape your oil is in, pay the $20 for an analysis.

dagwood2, you are a little too old school. Virtually all car companies have extended oil change intervals over the past 5 years at least and it's not just because they want to show a lower cost of ownership although that's part of it. Do you really think Honda, Toyota, BMW, etc would sacrifice their engine reputations just to show low cost of ownership? I don't. The 3000 mile rule is out the window with today's engine and oil technology. I agree with you the oil filter is often the lowest common denominator but still, most good filters do their job to 10K miles. I've seen several oil analysis results (from the companies you send in a sample to) that show the oil is still performing at 8-10K miles.
 
I have NOT seen proof that 3-5K mile oil changes extend the life of the engine. I HAVE however seen first hand proof that 10K mile changes with synthetic oil and a good filter does not impact the life of the engine.

Honda recommends to change the oil in 12 months if the mileage didn't trigger the M.M.
 
My M.M. told me for oil change after first 5,000 miles, then 8,000 miles later and MM shows I still have 40% left. I think may be a change of acceleration habit, now I accelerate slower and off the gas pedal earlier.

I have a 13 year old vehicle with a supercharger, which creates boat-loads of heat. Plus, I drive in a dusty environment, where it can be 100 degrees in the summer, -10 in the winter and I climb/descend over 3,000 ft to commute to my job. I don't care what they say, and anyway my manual has the severe duty at 3000 miles. You say most good filters do their job to 10k... I don't know what you call a good filter, there are only a few I'll use, but a couple of friends of mine and I did both a lot of research about filters, then a sort of hands on test, using different filters and seeing how long it took for the oil to get dirty. Only Mobile 1, Pure One, and AMSoil stood up to 3000 miles, much less ten. Fram is junk, even the ToughGuard.
So if you want all that junk floating around your engine for 5-7k miles, go ahead. I like my car.

You sound like the perfect candidate for an oil analysis. Why guess?

Recommended Engine Oil (Viscosity) by trcm
May 05, 2009 (2:09 pm)

My wife and I purchased a new 2007 Honda CR-V in late 2007 (November). The vehicle had 45 miles on it when we drove it off the lot. As with any new vehicle (and being old school), we were careful to drive it easy for the first few thousand miles to ensure proper break-in. The vehicle currently has less than 10K miles, and I do my own oil service every 3K using Castrol 5-20W (recommended viscosity), and new Honda filter. After the vehicle had approxinmately 5K miles on it, we took a trip from Central California to Los Angles and back (approx. 700 miles RT). Upon our return, I noticed that the oil level was down nearly 1/2 quart on the stick. After another regular oil change followed by another 500-mile trip, I found the oil to be a bit low on the stick again. Honda recommends using 5-20W oil. However, living in a more moderate climate (Central California), I can't help to wonder if the 5-20W viscosity isn't too thin for our conditions! I wrote a letter to Honda expressingf my concerns and they resopnded that I need to continue using the 5-20W, and add oil if needed. Am I over reacting here, or has anyone else had this experience? Does anyone use a heavier (5-30W) viscosity?

What would you estimate your oil mileage to be, per quart?

Using the info I provided (1/2 quart in about 700 miles) would extend out to be approximately 1400 miles per qt. It doesn't appear to be a problem with short (around town) trips, just at highway speeds.

Well I think as long as you are under warranty, you'd best go with the type of oil stated in your owner's manual or on the oil cap itself.
 
You'll need a longer test to test oil consumption. You might have the dealer check your PCV valve, and also complain about oil consumption. Maybe there's a leak you can't see. At least the complaint will be recorded.
 
Generally, there's no cause for alarm here unless you continue testing and find that the oil consumption in miles per quart is slowly increasing as the miles pile up. An engine can use some oil and run forever, but when it drops to say one quart per 1000 miles, that really gets my attention, especially on a newer vehicle.
 
Next oil change, try to measure it very accurately. And make sure the dealer makes note of this on the repair order....and check the PCV system.
