Long time passing... sniff sniff. Seriously though. Fram no longer makes an XG -I think it was 9010? Ultra Synthetic Filter. I was in a retail auto sore the other day. Purolator still makes a "One" filter but the new "Boss" long change interval filter has no part number for Jaguar AJ33 and AJ34 engines, and, big surprise the major retailer had not one filter to fit my 07 Vanden Plas. I realize Jaguar never sold huge numbers of XJ's during X350 years, but this is ridiculous.

I believe Royal Purple makes a decent filter and there's a Bosch model for us, but most long interval filters are NOT available for these cars. I find it really annoying that Mobile 1 has a 20k Miles "Annual" oil, and Amsoil makes long change interval oils, but seriously, if I have to pull the undertray, and swap the filter at LEAST 2x during the interval, it's not saving me labor or time, so why bother. Plus even with 7.x Quarts/Liters of oil in the sump, I don't feel comfortable going past 10k miles (or even quite that far)

Interestingly the PO was clueless what to do for the car since it has light maintenance needs, so he obsessively changed the oil, several changes at less than 2000 miles. He also only put 4k miles a year on the car for over 4 years. Amazing to me was from 89k to 92,500 miles the oil stayed honey gold for over 3500 miles. I used to put inexpensive oil in used cars I purchased for a day or two to suspend all the deposits, then drop it and fill, which would stay clean for a while, but not this long. At least I know the bottom end is clean as they get! Nice to know. Coolant equally clean having been replaced, but I suspect the thermostat housing is crumbled inside like my last X350, since warm-ups take a bit longer than expected. I will take a look soon and replace the housing as required.

What filters do forum members like? I want something good, but prefer not to spend $15-20 on a TINY oil filter. It just offends my sense of fair play, lol.

 

Use a quality filter such as Mann, or a Jaguar OE filter, which is made by Mann.

Easier to replace the filter than the engine.

 

+1 on Mann. Use original W713/29 or longer W719/7

 

The oil change interval is 10,000 miles or yearly, so why would you need a "long change interval" filter ?

Anyway why not go on the internet and buy, it's a lot easier, if you haven't a Jaguar dealer near you. In the UK here they cost around £12 or you can buy the genuine Jaguar one for a couple of pounds more. I never buy them as I have my car serviced by my local dealer at not too great a cost.

 

There are many still available. There are Autolite,WIX, Hastings LF510, and Denso at Rock Auto. All are good.
These are all good filters. They are as good as Jaguar and Mann.

 

I have been using nothing but Jaguar OEM engine oil filters for my 2005 Jaguar XJ8L.

 

Excellent! I have been trying to cross refernce a larger capacity filter, since the OEM is really small. Not for capacity, but smaller filter means less filter medium.

 

Well that was my point exactly - if the recommended interval is 10k miles, and the filters are 5k, you need to drop the filter midway through the change - not that its difficult, but a filter rated for 10k miles would simplify matters - (the Fram Ultra Synthetic is highly rated, as is K&N, Royal Purple (not sure who makes it for them) and Mobile 1 Filter all rated for 10k Miles or more. I run Mobil 1 Extended - rated for 15k miles, and even tried the Annual rated for 20k miles. Again, I would never run oil that long, but knowing its up to the task means 10k miles is sure to be within its abilities and unlikely its lost its oily magic.

 

 

I'm glad it helped

 

I've used the royal purple filters almost exclusively since I bought my XJ 3 years ago. Expensive but they are an excellent filter.

One of my gearhead buddies actually made a statement a few weeks ago concerning oil change intervals. He claimed that auto manufacturers came up with the 3000 mile / 5000 kilometre distance oil change which would allow the vehicle to degrade or wear down internally at "an acceptable rate" which to me doesn't sound fat fetched at all.

Any thoughts on shorter oil change intervals? Beyond the obvious cost issue that arises

 

The 3000 - 3500 mile interval is fine if using conventional oil. My wife’s 335i has a 15,000 mile recommended service interval. You would never see a 100,000 miles if followed. Especially for the first change. That interval is designed to reduce cost on the four year, 48,000 mile free service period.
With premium oil I feel 5,000 miles is a little OCD. But it is very easy to see when needed and cost is minimal. The most difficult vehicle to service is the A-8. Pulling the air box and reinstalling doubles the work and time. The XJR is easy.
I use a Mitey Vac and then pull the drain plug to verify all is out. Usually the Mitry Vac gets more out than the drain plug. The XJR holds about 6-6.5 quarts. Sometimes 6 gets it to max fill level.

 

I apologize if this is redundant or appears elsewhere. I wanted to check back in and list filter model numbers I have. Some of these are out of production, thus my original post, but hopefully this will help someone looking to cross-reference.

I have used Royal Purple, Bosch, Purolator One and K&N. For full synthetic oil value, I plan to use Mobil 1 extended - it's $25 for 5 Quarts vs 22 for the standard Mobil 1 - as I did on my XJ8L, but shorten my intervals to 7k-7500 miles. With 90k on the clock of the VDP, after running my previous car from 107k to 180k and want to see if the shorter intervals reduce oil burning and keep it quiet on startup when it gets to that mileage. At 150k +, my XJ8L had some valvetrain noise for about 1-3 seconds on startup. Ran great, but always made me wince. Current car is extremely quiet and sounds like everything is getting lubed. Not very scientific as there are multiple mechanical reasons for the differences, wear, oil pressure, chain guides, tensioner performance etc. But without a way to look inside, I can at least trust my ears. The current car has NO measurable oil loss due to burning or seal performance (or lack thereof) Goal is to keep it that way. My previous X350 was so good to me, having a younger, better cared for one is like a chance at redemption, and I plan to give it a bit more preventative attention.

AND: For the Ultimate: K&N SS-2009 Lifetime Stainless Mesh, reusable Billet 6061 T6 Aluminum (Aluminium for you Brits!) sold By K&N, but Manufactured byPure Power. I don't believe it filters particles as small as conventional mediums but claims to allow higher oil pressures. Whats better, oil circulating better but with more undesirable particles suspended in it, or "cleaner oil" that circulates less freely or with less pressure. A discussion for "Bobistheoilguy.com" perhaps but maybe a bit over-analytical for here, lol.
