Oil opinion

[redandy3575]

Hi all

I'm sure this topic has been covered before, but just wanna hear what grade of oil most of you use for the 4.6lt?

Reason for asking, the manual states to use a 10W-50 which I tried out once, but found the engine consuming it at a faster rate to which I now use 15W-60 Penrite HPR 15 which is much more kinder on the oil consumption. Thing is, I want to go by as per manual, but if I do, I'd need shares in an oil company to feed the engine. Has anyone else had this issue?

Several points: The manual (Owner's Hnadbook) specifies a range of viscosities dependent on ambient temperature ... e.g. from 5W-30W in very cold climates to 10W-60W in warm climates

Further: are you losing oil because of leaks or because the engine is burning it? I was going through a heap of oil and discovered it leaking from the sump bolts which were adjacent ot the cross bolts. I removed/replaced the sump using a 'rubber' gasket and putting Loctite thread sealer on all the bolts. Problem solved.

I currently use either 10W-40W Magnatec of 15W-40 Magnatec diesel in my 4.6. given that it's an "old" design engine. My personal view is that 10W-60W is too high.

This is a topic bound to stir all sorts of emotions :eek::wasntme::angel: I try and stay away from full synthetics because of the flat tappet design. If the vehicle had roller rockers, I'd use synthetics.

I have been running Burson 20-50 with no problems. I use an engine flush and find that the oil stays cleaner afterwards.
My rangie has 278000 up and uses a little oil, but not much. Its always better when the oil is fresh using very little.
Cheap maintainance, regular oil and filter change.

I use the same as you redandy...
No issues whatsoever. In fact, it seems to run a lot smoother.

I'm running Valvoline Syn Power 5w 40 in mine, have for the 2 and a half years I've owned it. Zero oil consumption, zero oil leaks and no tappet noise whatsoever.

I use Caltex Delo 400 in my Rangie (3.9, but for oiling purposes the same as a 4.6). While technically a diesel engine oil it is fine for petrol engines and has high zinc levels as required by flat tappet cammed engines.

My preference is for a single origin, cold pressed olive oil.

I'm not overly fond of the peppery ones, although they can be very nice with the right food.

Definitely has to be local, the imported stuff is well oxidised by the time it arrives here and is usually rancid :D

Otherwise if that doesn't tickle your fancy, there should be some good info here http://www.aulro.com/afvb/good-oil/ ;)

Yeah I found that too. A lot quieter & smoother. Just as we'll, cause I just bought a 20 lt barrel of the HPR 15.

I've got a very slow leak near the timing cover, which at the moment is not a huge concern.

The timing cover oil seal is reasonably straightforward to replace. There is some discussion on this elsewhere on this forum. Don't let it go too long without attending to it.

here in uae warm climate so i am using 20w50( acdelco, castrol, shell elf ...etc in summer and 10w40 ( adnoc, elf, caltex ) in winter, i noticed increment in consumption in my autobiography 1998 model than my wife,s 2001 range rover with thor engine also 10w40 more than 20w50.

I use GTX 10W40.

Just recently I had a middle aged lady bring SAE30 diesel oil up to the counter, to which I asked where she was going to put it, "oh, in my new M class out there"...... um, good try...

:lol2:

At least she was trying to top it off, most wouldn't know where the bonnet release was located.

[bruce p38]

I use 5w40 As my manual states He's done over 570,000
with one rebuild so I guess that's pretty good ! No oil leaks and I
use very little That's a 4.6 1995 model Gems

[mtb_gary]

15w40 for me and always with a new filter. Usually every 5,000k or 6 months which ever comes first.
