Motor Oil?
I'm nearing my first oil change since becoming owner of my 07' XKR. I was wondering what oil do you guys use, synthetic/regular and what brand? The asst.service manager at Jag said they charge 80 bucks and that's for regular oil. I was thinking of the Mobil 1 5w30. Any input is appreciated.
Cheers

I don't know about the 07s, but the 5.0 Supercharged motors take 8 quarts of full synthetic (from the factory at any rate). That's about 10 bucks a quart anyway, and so that's easily 80 bucks or so. Add in filter and labor and it's a 110 or 120 dollar oil change. Fortunately, it only happens once a year or every 15k miles.

I don't use advanced search much, but if it has a "Tone of the thread" option, you could search for "Snarky," "Bloviating," or "Contentious" threads and find most of the oil ones!
Edit: Better yet, *oil* returns 500 hits from the forum home page search bar! you have lots of reading to do!!!

You can't go wrong with what's recommended in the owners manual. Beyond that, use whatever makes you happy.

Oil from AutoZone or similar is fine...
...for not risking my factory warranty coverage, I make sure that the oil I purchase has the required ratings (IL4 or someting like that without looking it up). Generally I get brand name oil but, nothing particular. The last change I did I used Castrol GTX. I also get my oil filter from the same source.
For most street applications, IMO, synthetic oil is an overkill. I only used synthetic in my race cars where the extended high RPM and high temps definitely require the superior high temperature qualities of synthetic. For street driving you should never get to those engine stress levels and temperatures. I always used normal oil in all my street engines, drove them probably harder on the street than most anyone and still never had an oil related failure.

From The 2009 XK Owner's Handbook
Here's what the 2009 XK owner's manual says:
"Engine oil specification
5W-30 engine oil, meeting Jaguar specification WSS M2C913-B is preferred. When topping up between oil changes, make sure that you use
oil that has the correct quality level (API service) and viscosity grade.
oil that has the correct quality level (API service) and viscosity grade.
Note:
For maximum fuel economy, 5W-30 oil is recommended.
Engine oil temperature ranges
For climates ranging from -35°C (-31°F) to +50°C (+122°F), the following oil viscosities may be used:
0W-30 will protect from -35°C (-31°F) to +35°C (+95°F).
5W-30 (preferred) will protect from -30°C (-22°F) to +35°C (+95°F).
0W-40 will protect from -35°C (-31°F) to +50°C (+122°F).
5W-40 will protect from -30°C (-22°F) to +50°C (+122°F)."

From what I've read, and I'm not a petroleum engineer, synthetic oil "drains down" from the cylinder walls far more slowly than does dino oil. So, if you rarely drive your car, you're much better off with synthetic oil since it will better protect your engine at start-up. Also, how you drive (engine rpms, trip length, climate/temp/dust/etc.) also play a role. Oil, both syn and dino, never wears out; it just gets dirty and the additives lose their efficacy. Either one can adequately protect your engine, provided it meets the manufacturer's specs. Stop/go short trips are engine killers, since the water in the crankcase never gets hot enough to evaporate. Note that H2O is a natural by-product of internal combustion; you can see it dripping from your tailpipe sometimes, and as a cloud of water vapor when it's cold outside. If you rarely drive your car, you should change your oil (syn or dino) at least once a year or preferably sooner, since water in the crancase can become corrosive. Oil is cheaper than engines. Just my $0.02.
Depending on your driving conditions, either dino or synthetic appears to be acceptable, provided the spec. meets or exceeds WSS M2C913-B.
Since my car is a daily driver, I use dino oil - no need to spend the extra $$$ for synthetic.
Hope this helps.
