General Gen 3 B58 poor reliability

[HereinDaRockies]

I assume our Grenadiers have the gen 3 b58?

Why do you assume?

I've seen this guy's videos and I don't put a lot of faith in what he has to say about very many things. There are just too many variables to know what his issues might be. Change your oil early and often (every 5k miles for me), don't rev the piss out of it and you will be fine.

The B58 comes in many formats and tunings.
He is talking about the high output sports versions.
Not the version used in the Grenadier.
The Grenadier engine has been detuned (as stated) and remapped for reliability.
In Australia we also get the B57 diesel (my vehicle) which has again been massively detuned for reliability.
Keep in mind also the gearboxes used in the Grenadier and max torque figures below highlighted for petrol/gas (8HP51) and Diesel (8HP76).

B58 to date is probably the best inline 6 BMW has ever produced.

It's as smooth as a gravy sandwich! I love it.

I would say the Ineos engine is retuned to suit the application. The Ineos tune gives a high torque rise early. It flattens out the torque curve and give higher horse power lower in the RPM to perform more like a truck engine and not a performance car.
What I found interesting was what he was saying about the oil viscosities particularly the 0W-12 he mentions. Oil viscosity seems to be a contentious topic at the moment, and it doesn't matter what brand the 4x4 is. I had an interesting discussion with a Land Rover owner wanting to change his 6 cylinder Defender to a higher viscosity for towing and also have had similar discussions with several Toyota diesel owners considering similar changes.

That's not a new issue. The hurr-durr of the seventies with thick single weight oils and 3000km oil changes persists.

Short intervals hurt nothing in the vehicle, but are pretty darn wasteful of natural resources of they're only used to 30% of their capacity and discarded.

And nothing changes even when there are Toyota trucks with over 1.6 million km, towing/hauling for the majority of those, all run with 16,000 km oil changes of 0w20 in hot places like Texas.

The Grenadier will be my 5th b58 (X3 M40, and 3 X5’s) and never an issue. Always 5K oil changes.

All your b58s have this tapping sound, esp when cold?

 

[Tazzieman]

Normal I believe.
Injectors/HPFP
Sounds a bit diesel-like when cold.

What was your advice to the Defender and Toyota owners regarding oil viscosity as I guess it would be relevant for us.
I know you would not want to be held to account for any advice you give so I would fully understand if you don't give us the information, but maybe if you tell us what oil you use yourself that would be helpful.

Cheers,

Steve.

Tassieman got the answer before me!

Lots of discussion with 300 diesle owners about 0-20 oil.

5-30 for the win in that conversation.

And the 300 series small 5.5 litre capacity sump, high oil consumption, and 6 month service intervals.
They might have reasonable fuel capacity, but they need a long range sump.
I never realised the Toyota 300 series used a 0-20 oil.

 

[landmannnn]

I have read that going from say 5w30 to 0w20 reduces fuel consumption by 1.5%.
Likely as not the reason for manufacturers going there, longevity of engines being secondary.

I know nothing about oil from a scientific view, but I've been told that the use of 0 rated oils is all about fuel consumption, or rather helping achieve emission requirements. Whether that leads to lesser engine protection is the main point of discussion amongst others I have spoken to. Certainly in harsh conditions a 5-30 is a safer bet by all accounts. If going from 11.5L/100km to 11.67L/100km is the trade off to better engine wear, I'm ok with that.

 

[Quartermaster]

Anyone thought about the fact, that modern versions are developped especially for the thinner oils?
When i got my last G-wagon with the OM 656 inline six, it was designed for 0w20 oil, but my dealer put "thick" 0w30 in it, because it was easier for him to have just one oil for all. Didn't like that.

My inner love for the S50/52 wants to fight over this comment... But I'd have to agree, the B58 is a fantastic engine in virtually every way (ok, the oil filter placement isn't great)
