Yes! Your oil will be good. Changing every 3k miles or 3 months is stupid!

No! Your oil will beyond recognition. So full of metal it won't even be able to be analyzed!

1st oil change - 3 years after delivery...

BTW, the scheduled maintenance on Jaguars is free at the dealership, just like it was on my BMW M3, so I'm not trying to save money... Honestly I just rarely drive the car and had not even realized that it had been almost 3 years... I thought it was like 1.5 years... The car runs like a dream, never had a single problem with it, that's why it has never been to the dealership or had a single service (Couldn't say the same for my E46 M3 though 
)...
Anyway, I usually just change my oil once a year regardless of mileage, so this 3 years thing with my Jag is an anomaly... I know it's not a good idea to go past 1 year for oil changes...
The other interesting thing is I am probably going to buy the car when the lease expires this August...

Out of Warranty
A few major problems, the first of which is, whatever the condition of the oil or your engine, you will totally void your warranty on the IS - as you already have on the Jag. Regular oil changes are a condition of your vehicle's warranty. Any engine problems you may experience, for whatever reason, will be on you.
Back in the 1920's there was a school of thought that dictated you never changed oil, only the filter. The logic was that the high temperature of the engine actually refined the lubricant as you drove. As strange as it sounds today, it was probably true back then. Oils were pure mineral oil (or "Rock Oil") that consisted of nothing but lubricant. In those days engines turned much slower, with far lower compression, wider tolerances, and lower stresses than a modern powerplant. Cars driven long distances, primarily on the highway really did not require frequent oil changes. That was then, this is now.
Today's engine oils are more than half "additives", including stabilizers, detergents, surfactants. anti-wear, anti-foam agents, and a dozen other components that clean, protect, lubricate, and cool your engine. These components "wear out", sacrificing themselves on the job. When they're gone, your oil is no longer performing its mission.
Your low mileage application, infrequent driving, short distances, and heavy applications of throttle are the worst possible operating conditions for an internal combustion engine. Without a long interval of highway driving, water condenses into the oil and is not boiled away. Dilution of the lubricant, loss of detergents and other cleaning agents, not to mention the scuffing your cylinders are probably taking probably means you will reduce your vehicles to smoldering heaps before your reach that 15,000 mile mark.
Despite their light usage, the service you describe is considered "heavy duty service" because of the above conditions. You should observe the 5K mile interval religiously. Even in extremely low mileage situations, most oil companies recommend a change every six months.
We used to have a fellow on the RX forums who constantly bragged about "his" oil (he was a MLM dealer) and its miraculous properties. It NEVER needed changing. I think it was at about 23,000 miles his engine seized. A new engine was the solution (at something like $13,000) and he was stunned. He was REALLY mad when Lexus refused to honor his warranty as he'd never changed his oil. He posted several diatribes on CL about Lexus, and their lousy quality product and terrible service, but his previous posts came back to bite him. "His" oil, backed by a "full replacement warranty", proved to be no warranty at all. The manufacturer of the product wouldn't even answer his correspondence. He was stuck with a $13,000 coffee table. We haven't heard from him since. I wonder if he changes his oil now?

Lil4X: Thanks for the interesting information... I totally agree that short trips are very harsh on the engine... Please don't think I'm disputing any of what you say, and definitely don't think I'm advocating 3 year oil change intervals... I just want to share my finding as I have not seen anyone go this long with factory oil before...
Funny story about that guy and "his" oil... hehe... To me oil is oil... I really don't care... I have no idea what oil is in my Jag as it's from the factory... I'm pretty sure it's not synthetic though... I guess Blackstone will have the answers...
I am going to change the oil today... I called my local shop and told them to have a clean container to store the oil until the blackstone kit arrives... Believe it or not, I'm actually slightly nervous! hahah

If this one is a keeper, I'd be nervous too.
Mobil 1 says modern oils are 80 percent base stock and 20 percent additives with their own base stock which is where you get into the thick of 100% synthetic or not because the additives are rarely in synthetic base stock. I learned a whole lot about this reading Mobil's case against Castrol a few years ago. IMHO, I still don't know beans about oil though, other than what has worked for me, and that any synthetic beats conventional oil on extended drain intervals. If I really want to know something I go to bitog and sift through the holy wars about oil.

Audis on the Longlife Service Plan will go 20k miles between oil changes but even they say that if you haven't got to 20k within 2 years, change the oil anyway as it will start to degrade after that. I'd get it changed asap.

yet they still have more problems than other makes. Preludeonline admin's 03 745 navigation system has been replaced 4x, the water pump failed at 52k causing the engine to seize and probably needs replacemant or a big repair, thank god he had an extended

Prelude has its own fair share of problem too. The differential-type device on the Type SH, the tail lamp, and the premature deterioration of the trunk's weather strip. But this is off topic and I am not into BMW bashing.

I use mobile one on all three of my cars. My ’87 Vette is rarely driven so I change the oil and filter once a year when I get it inspected. My 2004 Maxima and 1992 SC400 I do every three months. I could probably go 6 months on the SC400 and Maxima but it doesn’t pay to skimp in this area.

Sorry...perhaps I labeled it wrongly It's not so much the idea of the thread itself being a joke as the idea of oil changes that extended...even with synthetic. In most cases, it's best to go 3000-5000 miles depending on driving conditions. Maybe a little more with synthetic...but even with synthetic, though the oil doesn't break down as quick, the packages in it do.

This is weird.. Ive been changing my oil about every 10,000 miles and I havent had ANY major issues with my 93 ls other than routine maintenance. The car has had mobil 1 since 20k miles and im now on 190k. The synthetic causes much less friction in the engine and doesnt need to be changed that often. on average I go about a year to a year and a half before i change it.
