Oil Suggestion for New Guy

[Jmeyers278]

Okay, I just bought an 05 Land Rover lr3 with 65k miles. It has been serviced since new at the local land rover dealer. They did oil changes every 7500k with the recommended conventional 5w30 castrol. I am not a guy who gets minor service done at the stealer. I am wondering what you guys think on what oil and filter to use. The book calls for 3,000 mile changes but is kind of indirect about it. It says and I quote..

" The oil consumption of your engine is influenced by many factors. New engines reach the normal value only after 5000km (3000 miles) Under high loads you engine will also consume more oil."

It says nothing else about oci

It then says

"Recommendations for all climates and conditions

NOTE: Recommended oils are complete in themselves and additives should NOT be used
NOTE: It is essential to change the oil MUCH more frequently if the vehicle is operated under severe conditions.

Use only oils Certified for Gasoline Engines by the American Petroleum Institute (API). To protect your engine's warranty, use and SAE 5w/30 oil meeting specification WSS-M2C929-A (GF4)"

That is straight out of the book guys. I also plan on keeping the car for the long haul!
Thanks
Jim

My first question is if the manual recommends 3,000 mile changes why the dealer was doing 7500? Perhaps the 3000 figure is for severe duty as many OEMS have shorter intervals for all fluids under their "severe duty" recommendations.

Does it have an oil life monitor?

Just my opinion. but I would run Mobil 1 oil at 5-6,000 mile intervals. If you do an UOA at that interval and it shows you can go further than go on out if you feel comfortable. For me, $24 a jug of M1 and a filter for another couple bucks from Walmart means 5-6000 miles is still cheaper than one dealer oil change with conventional oil.

Straight 30 weight. Nothing else.

A 5w30 Synthetic Blend such as Motorcraft or Pennzoil would be a good step up your previous conventional Castrol (and not cost much more money if any). I drove a 1998 Land Rover Discovery for my last job, in which we used 5w30 Motorcraft with an OCI of 5,000 miles that ran very well.

As a rule of thumb: Conventional oil is recommended for 3,000 miles of use, while Synthetic Blend is recommended for 5,000 miles.

If you want to keep a 7,500 OCI, you could also consider a full synthetic - M1 is what is most popular on these boards.

For filter, you cannot go wrong with a Purulator PureOne.

M1 5-30 has the spec you need. Here a link to their PDS.

If its been running 7500 mile ocis with GTX your gonna have some serious varnish issues. I suggest running a few 3k ocis with Pennzoil Ultra just to clean it up and then stepping up to 5k ocis for a while. Maybe after its all cleaned up you can extend it quite a bit more depending on your driving habits

Assuming that it's the 4.0L, tig1's suggestion is correct. Whether or not you want conventional or synthetic is up to you, but the Mobil 1 5w-30 meets the requirements for WSS-M2C929-A.

It is the 4.4l jaguar v8

Also I am a pretty conservative driver with the occasional full throttle get out of my way pass when the road rage kicks in

The spec is a Ford spec which I think is an energy conserving oil.

I think it aligns with A5/B5 ACEA specs and is backward compatible with the older 913 spec.

OCI in UK is 15k miles.

Not sure I would leave it that long myself.

My Pathfinder has a long OCI specified but I change it at 5k miles, spec ex for 18k miles.

I would probably do 5k miles myself but you have to consider different fuels in the US, with more sulphur.

I read on here that this is what hammers TBN much more than the ultra low sulphur fuels we have in the UK.

If you intend to keep it for a long time you could consider an additional bypass filter.
Petrol Discovery's are rather rare in the UK, more popular in places like UAE and apparently Russia.

You might get more targeted info on a Land Rover forum.

There are also lots of specialist Land Rover magazines that might have info for you.

Possibly even some places to buy parts in the US or Europe.

As far as exact oil choice goes Land Rover and Jaguar tend to spec Castrol in the UK.

Though Mobil will certainly do a very good oil up to the job.

If a Land Rover dealer put conventional oil in my V8 Discovery I would drive it over his cars bonnet.

^ The above phrase isn't referring to OCI. ^

It is stating that the engine won't be fully broken in until it has 3,000 miles on it and may consume more oil then normal until it is fully broken in.

Look for a maintenance table. The table will show the OCI for normal service and another OCI for severe service. Sometimes the maintenance table isn't in the owner's manual, it may be in a separate booklet such as a warranty policy.

the scheduled maintenance book says 6 months or 7500 miles

Well just start with a few short ocis with a good syn and work your way up from there. Im a SOPUS guy but I guess M1 is ok.....

those land rovers are Money pits i have a friend that has the big one 4.6 and replaced almost everything. very strong vehicle but expensive to fix

Automobiles are money pits....I love the rover....they aren't terribly expensive if you can wrench yourself and shop around for parts

 

[bigjl]

I think they might suffer slightly with the higher sulphur fuel content in the US Nd the use of conventional/dino oil.

They wouldn't put that anywhere near a modern vehicle in Europe.

Perhaps they did in the old 3.5 and 3.9 engines derived from the all alloy Buick lump, but these modern engines are not even remotely similar.

I looked at a Discovery 3 prior to buying the Pathfinder and maintenance was my biggest worry, albeit I was looking at a TDV6 with the 2.7 rather than a V8 or V6.

Also I could get all the toys on an '08 for the same money as an '05/'06 Discovery 3.

Don't forget to find some Land Rover forums to glean more related info as they can be cheaper to own than some think.

Especially if you can do most of the routine stuff yourself.

Possibly even a bypass oil filter setup.

Oh oh. I ran the Mobil lube selector and they claim to not have an oil for that, only for the 4.0L. Does the manual recommend something different for the 4.0L versus the 4.4L?

In a pinch, M1 0w-40 might be the safest option.

Why a 0-40. The book calls for the same castrol for both engines in the book

The reason I mentioned that was because the Mobil lube selector claims to not have a suitable lube for the 4.4L. Either the lube selector is wrong or there was a back specification on the engine for some reason (i.e. API/ILSAC oils didn't perform as planned). If the latter were the case, then M1 0w-40 has enough ACEA and proprietary European specifications that it would be a safe bet. However, if the manual insists upon an API/ILSAC 30 of some sort, I don't see a problem with that.

 

[Jmeyers278]

I went on just about every oil website and the only one with a recommendation for that motor is the pennzoil site. It recommends pennzoil ultra 5w30....not even castrol's website claims to have an oil for it and the manufacturer recommends castrol gtx

I'm with Garak.
When in doubt I would fall back on that oil. It has the most certs on the planet and is a great oil. I'm a sopus guy myself but the M1 0w-40 is the most decorated oil available. If you are planning on running a 7500 mile interval that would be my oil. Or red line 0w-40 but it costs more and is harder to find.
