You can call me crazy, you can argue it, but I stand by this...
I'll tell you, don't listen to the big oil companies or the manufacturers. They are expanding the service intervals to cheat the C.A.F.E. regulations on oil and emissions. They also get more money out of you when your engine sludges up because engine sludge is not a warrantable issue.
Please, I know all the big companies are saying now that you can go longer with fewer oil changes, and technology has advanced, etc. While technology has advanced, a lot of this is hooplah. Manufacturers have to meet certain C.A.F.E. criteria, in the USA especially, for their products to be accepted and legal. In order to do this they have to make it seem, on paper, that the oil consumption and emission output is below a certain threshold. The engine and oil technology has not advanced that far!
Change your oil and filter every 3K to 5K miles (or 6 months, whichever comes first)!
Having spent many years working in the modern automotive industry as a technician, I can tell you that if you change your oil every 10,000 miles, your engine will not make it past 100,000 miles, if you even get that far. Engine oil breaks down over time and use. I don't care if its the top of the line full synthetic. Mobil1, AmsOil, whatever. It breaks down . Heat and friction break down the oil, it loses lubricity and collects contaminants. By 5,000 miles your oil's life span is spent. The lubricity of 5,000 mile oil is course and gritty and full of contaminants from the engine. What are the contaminants? One source is the small amount of carbon that slips past the piston rings, another is the broken down oil, also known as SLUDGE. Another contaminant is moisture, yes moisture is a natural byproduct of internal combustion engines! This makes the sludge thicker and tackier! These things make the oil thick and goopy, left long enough it literally turns into gel, and by 5,000 miles your filter is plugged up and no longer filtering. Once the oil filter's internal filter media is completely plugged, there is a spring loaded bypass valve inside the filter that opens and your oil isn't even filtered anymore.
Long story short, don't go past 5,000 miles/6 months for an oil change. Ever. No matter what the owner's manual says, no matter what the oil bottle says. Do not do it.
P.S. If you've not reached 5,000 miles in 6 months, still change the oil at the 6 month mark. After the engine has been run, the oil can still break down, because now its been used, even if it just sits. Most used oil has a shelf life of 6-7 months, once its been used (meaning run thru the engine and heated up.)
