Why 7 Quarts of Oil in the 3.0 V6?

^^^+1000!!!^^^
I agree 100% that the ones saying 3k or 5k is so much better then OEM recommended OCI's. Splitting hairs IMO. I guess what it all boils down to is "to each their own". But like you said, as the miles rack up the OCI’s will play more of a role. Engine “failure” rarely occurs due to bad oil, you really have to push the interval for oil to fail. Unless you have other issues that could have been noticed during an oil change.
Also I might add I'm in your shadow when it comes to Aviation. I've only got 12years into it. lol But very familiar with MSG-3, I wish I had your experience and data to shut up a lot of arguments over conventional or synthetics. lol I usually just bite my tongue because without data or black n white prove it's very hard to change anyone’s mind.
I re-read my post and it may have come off rude, so I apologize. It was not my intention. Guys like you DO help to get the facts out, I try as well but perhaps not as efficient.
Anyone ever wonder why a lot of Farmers use their used motor oil from their cars in their tractors? …hint… BECAUSE IT’S STILL GOOD

sorry if I caused you guys to start pulling out your resume's to discuss my feelings of how I want to take care of my car which helps me sleep well at night.
Anyway, The responses are great and I was glad to read I am not the only one changing oil way to often according to the dictates of the Jag gods that wrote the manual.
And thanks to all, because at one time or another you have all answered questions I have had about the best way to take care of my car and really appreciate it.

Thread resurrection (I found it whilst doing a search):
One thing that people forget is how much the engine oil helps to cool the engine, especially when it is passed through an oil cooler. A higher oil capacity helps to keep the oil at a lower temperature and therefore draws more heat away from the engine.
Ever wondered how the Cadillac Northstar engine can run with no coolant? Oil capacity is one of the reasons: Northstar engine series - Wikipedia, the free encyclopedia

Maybe its because I light up a dobee every time I get in the car after I change the oil, I don't know....it just runs better
. Seriously, All I can say is it just seems to me the engine sounds better and just feels better like its thanking me for taking care of it (no I'm not high now). What can I tell you, I love that car.

Honestly, the car runs better with the full synthetic in my opinion - I change every 8,500 miles... that;s my $0.02 here... done..

It's all about reserve capacity for periods of transient high demand, cooling and the ability to hold contaminants in suspension.

FWIW,
My 07 BMW has even longer oil change intervals than I am used to. Apparently it monitors driving conditions and several other factors - not just mileage. The 3.0 I6 takes 6.8 qts of full syn and went 14k on its last oil change. Although I didn't send it out for analysis, the oil looked pretty damn clean coming out.
My daily driver is a Toyota Solara (bought new) with the 3.3 V6 (takes 5 qts). It currently has 268k miles on it. I change the oil at Jiffy Lube every 5k with conventional oil. At 200k a compression test was done and all cylinders were roughly equal and had excellent compression. The mechanic said at this rate I should have no trouble reaching 500k. I bought this one new, so I know its entire history. Keep in mind that 90% of my driving is on the interstate.
I'm going to change the oil in the BMW after 7500 miles and I'll send it out. Personally, I think there is too much hype surrounding overly frequent oil changes - especially if you are using synthetic...but hey, it's your money and your peace of mind, so do what makes you feel best...

When manufacturers give a suggested oil change interval, it is done to ensure that their products make it through to the end of the warranty period with as little problem as possible. It also is reasonable to assume that the periods and oil quality recommended is a good number to follow after the warranty is expired.
Lots of fleets exceed the mileages for oil change intervals with little or no issues but it is buyer beware as without a way of monitoring the additive package and dilution of the oil one shouldn't do long extended drains intervals, and additional by pass filtration is usually necessary.
I know from experience that oil can run 10's of thousands of miles provided it is properly cared for but for the average car it isn't worth it. Just use decent oil and change as directed.
Modern vehicles have the engine oil life monitor and can serve an excellent purpose for consumers.
