    Hi All - First off, great forum and great information. I have been lurking, reading, and learning a lot over the past few days. I am particularly grateful for the great write-ups on oil changes and diff/tc fluid changes. I will be doing my first DIY oil change on our 2012 LR4 as soon as the gear arrives from Amazon. Tired of the stealership prices. I have already ordered the Mobil 1 EP 5W-20 so that will be going in on this oil change.

    Today, I got wind of the Costco deal for Kirkland Signature 5W-20 Full Synthetic that is $24.99 for (2) 5 quart jugs after a $5 off and free shipping (local sales tax applied at checkout). I am getting some of the 0W-20 for my GMC pickup truck, but I wanted to ask the brain trust here if this brand of oil is compatible with our engines?

    The site says:
    "
    Applications
    For use in gasoline, ex-fuel or gasoline-electric hybrid vehicles requiring SAE 5W-20 API SN PLUS, SN, SL and ILSAC GF-5, GF-4 or previous standards. Approved for use in all GM gasoline engines requiring dexos1™ Gen 2 5W-20."

    Thanks again for all of the help and I look forward to your replies.

    It doesn't list the Land Rover spec that's spelled out in the manual.

    For as cheap as motor oil is--even the official Castrol Professional--on a per-mile basis, why risk it?

    I know a lot of us here are running Mobil 1 5W-20 EP or non EP with no problems.

    My local dealership throws Pennzoil into all of the rovers and jags.

    Starting to wonder if it actually matters... Especially since most LR4's are out of warranty now.

    because the ford 925 spec is obsolete.

    Doesn't mean it never existed and the Land Rover engines no longer require it. It's been superseded, and the spec of this Kirkland oil doesn't say it meets the new spec.

    Thanks guys. Appreciate the input. I love a good deal as much as the next guy, but don't mind paying the correct amount to ensure that the specs are met.

    That said, I got to thinking about this because when I was at the dealership recently to buy a jug of the "oh so special" coolant, the service manager told me that the $45 per gallon coolant that I was buying is the exact same stuff that is in the jug with a Jaguar label that sells for $110 per gallon. Are we paying for brand names and marketing unnecessarily? Is it just as good to run some Kirkland 5W-20 oil for 5k to 7k?

    It seemed like the folks on the BITOG thread thought it was perfectly fine for most uses and that it was made by Warren, etc. If I can do 5 oil changes for $100 (plus filter costs) then I would be way better off than bringing it to the dealer for several hundred per oil change.

    The 5.0L uses a mechanical phaser system for the variable valve timing. This would mean adhering to a 5W-20 viscosity is important. The 925A which was superseded by 925B is merely related to extending oil change intervals. In LR's "wisdom" they thought 15k miles was reasonable... This probably had more to do with marketing (low service cost!) than anything. Run at normal 5-10k intervals and the 925 spec can be safely ignored. Just use a quality oil.

    I personally like to use something that is at least "recommended for" the original spec, although as mentioned above, it's probably not the end of the world. There are old threads discussing the spec in more detail.

    If you want to use the insane 15kmi change interval only specified in USA, then yes it's critical to only use oil that formally meets factory spec. The rest of the world had a 7500-mile change interval for normal service, half that for severe service.

    The Kirkland 5W-20 is probably fine but I'd change it every 5kmi, same as I would Mobil-1 5W-20, or any other oil that isn't formally approved by JLR. (Remember, JLR approval is not the same as "recommended for XXX".)

    :confused:

    As a Service Writer (not at a dealership), I can confirm there are different part numbers for the exact same part used in Jags and Landys. The prices differ as well. We always cross reference the parts to make sure we are buying the cheaper of the parts.

    as I do 5k oil change intervals, I will start using this oil going forward. I use M1 EP 5w-20 now and it's fine, but this is half the price. I don't anticipate there being any issues. Now the question is, 0w-20 or 5w-20?
