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 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

      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.

      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).

      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...

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

      I thought they'd been recommending this interval for years. What have they been recommending?

      Some of the Japanese manufacturers recommend 10,000-mile intervals for some of their cars.

      We do 5K mile intervals in both our Jeeps (which is like once a year, if that, lol), and I think we've decided on 12K mile intervals in our '06 CTD Ram. All are running synth motor oil. The Jeeps both have oversized filters too.

      I have been using Amsoil since 1974. It is a true synthetic oil not a highly refined petroleum oil that is fraudulently rated synthetic by API. Mobil 1 is also a true synthetic.
      I change oil and filter once per year at an average of 18,000 miles. I have owned Chevys, Fords, a Neon,Toyota trucks and two Avalons. Not one engine failure nor did any of them use oil. I had to top off the Toyota Tundra and neon with a half quart between changes. Neither ever got to the add oil level however.
      My 98 Avalon has 161,000 miles oil it and was one that Toyota has extended the warranty on due to sluge problems. Mine has no sludge and never did. It's the oil that caused the problems not the engine. Some mechanics have no clue what an API rating is all about.
      Don't forget to use a quality oil filter either. Amsoil and Mobil 1 have their own that filters smaller particles by using more surface area with superior, more efficient filter media.
      Using true synthetics is not only smart and cheaper in the long run it also reduces imported oil. Reducing imported oil means more money stays in the USA.
      Now you know someone who has been there and done that not a dealer who lies about the need to change oil every month or 3,000 miles to make sales.
      Even today's petroleum oil is good enough to go 7,5000 miles but why not use the very best?

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