I think this was mentioned a while ago but cant find the message.
I want to change the engine oil in my 3.9i Discovery today, its done 78,000
miles. Any recommendations on what oil to use (as long as its from
Halfords!).
Thanks
Richard

i used the 10/40 part synthetic from Halfords (big greenish bottles 5 ltr)
in my 3.9, no ill effects from what I can make out, although I do change the
oil at around 3k in mine because of previous mistreatment

On my 100k V8 P38 I did my 3-4k routine oil & filter change last bank
holiday weekend. I used Castrol GTX 15w/40 "for engines over 75,000
miles" whatever that means. The following Thursday on a trip from London
to Chichester my engine shattered a piston. No warnings, drama,
overheating, smoke or water loss just a nasty noise that at first
sounded like cam/followers knocking. New engine ordered and on the way!
Coincidence?

I used a semi synthetic 15/40 from a retailer in New Mills about £9 /5litre
branded Vauxhall kit pity you have to use Ha;frauds I've not noticed their
pricing policy as being competitive against real motor factors.

good 20W50 or 15W50 is best. The 50 part is most important. I'd not run a
pre-serpentine belt one on anything much thinner, from choice. Good 20W50
is getting hard to find though, I've got a tin of Halford's green 20W50
which is fine for the series III, but probably not all that good quality.

ideally, you want API SG or higher - but 20W50 with that standard is even
harder to find. 15W50 is getting more difficult too. 's down to all the
modern engines that run on gnat's **** oil.


Morris lubricants do quite a good 20W50.

almost certainly, but any 40 "hot" rating is a bit thin for most of the V8s.

Disco II and later RR with the "4.0" engine will run OK on thinner oil.

All my Land Rovers seem to have gone well on Castrol. I think I bought
Magnatec last time and the RRC engine hasn't used a drop in 6000 miles.
Shame that it leaks from the diff and transfer box at such a rate then
really!

decent stuff and whatever spec the book says. It'll prolly spec either an
API or ACEA code for the oil - generally, exceeding the required spec is not
a problem except with brake fluid, if you get it wrong: DOT 5 is not an
upgrade on DOT 4, whereas DOT 5.1 is. DOT 5 is silicon fluid and not to be
mixed. Just to make life nice and simple...

I don't have the specs for the 4.6 motor but I expect they're in the
handbook. mostly, with engine oil, better spec is better especially for
modern engines. API system has SF, SG, SH, SJ, and so on, I think up to SL
now, for spark ignition engines and a matching set CE, CF, CG, CH etc. for
compression ignition.

ACEA go A2, A3, B2, B3 and I think E2, E3... I forget what they all mean
but generally they advance in a logical manner. I think at least some of
the ACEA have dates as well, like A2:96

If you look at the LR site they seem to recommend everything from 5w30
to 10w60 http://www.ownerinfo.landrover.com/extfree2viewlrprod/index.jsp
handy site that you can download manuals remembering to allow for blank
pages that aren't included in the pdf.

I use the standard Land Rover oil, it's about 12 quid a gallon from my local
Landy specialist.

I've just bought Unipart green 20/50 for my 2.5 na/D 90 don't fancy putting
magnatec in it.

That's the stuff, V8s love it, Part No GUL7005, used to be GGL400.
Obviously they are still selling it then, I wasn't sure.
