Whats the reccomended engine oil for a d5 2.4

I know why its recommended because of the longlife and low saps for the dpf
And a few gramms less co2 emmissions due to the too low viscosity wich the engine pays with more wear outside warranty
But there are if you look good a few low saps 5w40 oils wich provide better oilfilm strength change them every 10000 miles to cap the oildillution percentages
They are even cheaper than the 0w30 oils and if you by it by 5 gallon cannisters you save even more

I do low milage any way i average 7000 a year i just want to put the correct oil in to protect the engine not botherd about price just best for the car regards mick

thanks so what was the outcome of the test what grade to use ? regards mick

as i said in post #2 above .
Was your cambelt changed ?

Its all co2 grammes at expence off the engine
And i doubt when they did the tests the oil was dilluted by 20% biodiesel wich cant evaporate wich is the case in regular cases in practical use
But when the complaints of rising oillevels came they didnt even know the cause! yet alone it proves they didnt even tested that worse case scenario because back then biodiesel blending was non existant
Wonder why audi turbo engines departed from the 0w30 oils? those seized up even without biodiesel dillution ! ok it where petrol turbo's with higher thinning temperatures
But i hope u get the picture


Btw the euro 3 engines all run good with 5w40 oil wich are roughly hardwarewise the same engines
Look at the specs for a5/b5 oils they all have lower filmstrength at pressures and temps where the engines need the protection the most than b3/b4 oils wich are the specs for most 5w40 oils

viscositeit bij 150 °C (mPa.s)


A1/B1

>=2,9, <=3,5; Xw-20: >2,6


A3/B3

>= 3,5

A3/B4

>= 3,5

A5/B5

>=2,9, <=3,5






So suggesting 0w30 has better protection because volvo and castrol say so they dont! and with absurd levels of biodiesel dillution it gets even worse!
But hey the few grammes of co2 reduction due to lower viscosity is better for the enviroment than replacement engines or in the best case more engine wear.
The only thing not to use high ash oils wich most 5w40 are is because of the dpf
Thats the reason pre dpf d5 engines used 5w40 oils even then also 0w30 oils where availible, because if wateroil is all that good why didnt they advised 0w30 oils for euro3 engines?
Dpf and emission pressures made them use 0w30 and that volvo thinks a bit extra engine wear is acceptible is fine but not by me!
Luckily a few low saps 5w40 oils excists!

Sometimes new insights due to practically experiences wich wherent availible at the time of the tests or design and common sense can be better than religiously obey what the volvo bible says
i have numerous examples of dealers regardles wich brand who dont know what they are talking about technicaly besides blurding what they are told to be blurding

i realised after i hit the button sorry but this seems to be such a confusing topic & i still don't know wich way to go no the cambelt was not changed just got one more quote to get tomorrow from a local volvo garage

Im wondering with my low milage that i do if the higher viscosity would give me problems with the dpf filter who the bloody hell invented dpf filters if it wasn't for that my mind would be made up do you think that 5w30 create a problem with the shorter journey user with the dpf ?

[copperknob]

yes i would use 0w/30 only d5 06my onwards volvo recomend it

Viscosity is not a problem for the dpf provided u take a low ash oil and normally 0w30 is lower ashed
But there are some low ashed 5w40 or 0w40 oils
On the other hand dpf where designed for 50 ppm sulphur in the diesel but the last 5 years its 10 ppm or less due to the en590 spec
So the sulphated ash buildup in dpf's is lower than anticipated

I only advise it to do it out of warranty ,not because of the stronger thicker oilfilm, but if something happens not oil related they grab any excuse if you didnt foolow up the instructionbook to not remburse you

if volvo recomended to pour a liter diesel in the crankcase you would also do it?

So what am i looking for low ash content on the lable how is it quoted by numbers or code or what brand ect & 5w30 or 5w40 the last 3 independant services state part no.she004 ultra extra 5w30 i wonder if the she is short for shell but you don't see that on the shelf any more its more of a garage brand even when i put the reg in euro car parts it comes up with so many oils regards mick
