What about oil change intervals using synthetics?
I have heard up to 10K and even 15K.
I'll begin using synthetic with my 2nd oil change and was planning on every 5K.
Anyone heard anythin on this?
What about warranty issues using synthetics for periods longer than what is specified in the manual?
I believe the recommended manufacturers (Mobil) intervals are 6 months or 6,000 miles. They used to say 1 year with almost unlimited miles. The stuff is literally indestructible. I'm switching as soon as I take my car out of storage next spring. Oil change at a whopping 700 mile interval.
I also use Castrol Syntec 5W30. As for intervals I do an oil & filter change every 5000. It's a very safe interval with synthetics and is also super easy to remember when the next change is due. I rotate the tires on the same 5K schedule.
I use Mobile 1 5-30 A few years back I read an article in comsumers report where they were testing synthetic motor oil and they gave it high marks they went on to say that Castrol was not a true synthetic as Castrol claimed Steve Bullitt#5499 Densecharger Zaino

I use 5W-20, exactly what the owner's manual calls for. Using anything other than that, may damage the engine. The oil has to get to all of the moving parts very quickly, and using thicker oil lessens the changes of the oil moving quickly to all of the internal moving parts. Getting 5W-20 here in town has been a little difficult at the moment, since so few vehicles even require it.

Extended oil drains are recognized and allowed by the manufacturer under warranty provided you conduct oil analysis. You must use an approved lab that has an extended drain interval program. "WEARCHECK" is a good one and you can view your account online. I use 5W30 also. As stated earlier, the 5W20 was a spec for better fuel economy and reduced emissions.

Where did you read that the manufacture agrees to extended oil drains?
Nice site whiskycreek,
However I doubt if Bob the oil guy speaks for Ford on extended oil changes. I could not find anything on that site about extended changes, I probably missed it. I will go back later when I have more time. Thanks.
