Ford has been studying the question of when to suggest oil changes, and they've hit upon 7,500 miles for 2007 and newer cars. Not only are modern oils better, modern engines are also better. You don't have carburetors metering poorly on winter mornings, tolerances are a lot tighter, and operating temperatures are typically a little hotter, helping to cook off the junk that accumulates in the oil. Some manufacturers use a sensor to monitor the health of the oil and light a service lamp when it calculates change is required. Ford contends that its customers prefer a set amount of miles between changes. The automaker also cites the environmental benefits that come from less waste oil, monetary savings, as well as extensive tests as positive aspects of the new recommendation. I'm convinced that the only reason to suggest changing the oil at 3,000 miles in a modern car is to sell more oil. Perhaps an air-cooled Porsche would stress dino juice more, and could sensibly require changes at 3K, but you can stretch to drain intervals that would make your father gasp and clutch his chest by running modern oils in your modern engine. Of course, your driving pattern has a lot to do with it, as well. If you're in town for short hops, you'll require a shorter drain interval than the guy running Mobil 1 for his highway commute and changing the oil at 25 kilomile intervals (raising my hand).

      I find this whole 3000 mile oil change thing ridiculous. I had a 2004 Subaru Impreza WRX back home in the UK and was told that i needed an oil change every 7500 miles and then a service every 15000. When i bought a 2006 one here I was told that I needed to have an oil change every 3750 miles and a service every 15k. I do way more freeway driving here than I did in the UK and most of my driving is done in 5th gear with the engine spinning at 3000rpm. No one can explain to me why Subaru recommend different intervals on the same car! So i'm ignoring the 3750 one and just going with the UK Service schedule. When I asked Subaru US what impact it would have if i skipped the 3750 mile oil change to the warranty, they said it would not. So it's all a scam to SELL MORE OIL!

      Grrrrrr.

      A good friend of mine is a chemical engineer, and he's changed the oil in his Audi (2.7 turbo driven moderately aggressively but not stupidly) once, at about 38,000 miles. He tests a sample every 2,500 or so and as long as its still good, keeps driving it.

      Remember, 3,000 miles was also the recommended interval back when engines were *expected* to regularly shed metal flakes, and synthetic oil just plain didn't exist.

      If 3,000 mile changes make you feel better, that's worth $20 every quarter all by itself. But for your car? Probably not.

      I change the oil in my car every 4000 miles and it works fine that way. It's an older version, so It wouldn't have all the nice updates the newer version have but she runs fine for me. I'm debating which oil I should though, synthetic or conventional? http://www.billsmithsauto.com/service.html

      I change my oil once a month. Our cars cover 30 thousand to 60 thousand miles a year.

      Oil is cheaper than engines. Period.

      jimmyc i change oil about 50000 on every car i have owned since 1960 and never had engine problems yet am driving 97 linc tc with 350000 i sold service for years to costomers for oil changes that they didnt need in reality

      What? I had a 1984 Ford Crown Victoria LX and the oil change intervals on there were 7,500. It was a civilian model vic with a 5.0.

      Then again, the older vics were built when quality was job 1 at FoMoCo, and they were world's better than the newer ones in terms of quality, materials, construction, etc. I had a 94, and currently drive an 01 LX HPP, both pale in comparison, though the 4.6 is a better engine, imho.

        Yeah, i got a 99 cv. I wish it had the style and design of something like an 87 as those boxy-style cars were definitely cooler. Although i agree, the 4.6liter engines are better. They are more powerful for sure.

      Audi recommends 10000 mile oil and service intervals
      Porsche recommends 2yr/20000 mile oil/service intervals.
      Of course thats regular maintenance duty schedule.

      Good for Ford.
      The oil filter element for the 2gr-fe is very small, ~125-150 square inches of flow area. So that limits the duration of oil changes.

      But if you do a total engine oil change with 6 quarts, replace the filter at 5000 miles, and top off with another quart 10,000 miles is do-able for the 2gr-fe.

      Finally something the europeans are ahead on. Service intervals. The VW/Audi/Seat/Skoda family of diesels require a service for every 30-50.000 kilometers, depending on the way you treat the engine (high revs / cold engine).

      My 2001 Skoda Diesel signals a service and an oil change every 45-48.000 kilometers, because I'm easy on the throttle, and never go over 2000 rpm before the engine is warm.

      The car has now driven 230.000 Kilometers (143.000 miles).

      Cheers

      I try to stick to 3K changes in my daily driver. It's a 350Z, with Castrol Syntec, top quality filters, and 90% highway miles. At least I won't feel quite so guilty when I sometimes extend the changes to 4K or so...

        Absolute wste to change synthetic oil at 3k miles. You can go significantly further on conventional than that.

        At 3k, you have used up about 1/3rd of the oil's life.

        You are just throwing your money away.

      BMW recommends 15k for both my 06 MINI and 06 M5.
