It absolutely does not. You don’t know anything about these engines.
No, I’m an engineer. Not mechanical though. Working at a dealership isn’t what I’d consider a sign of competency or knowledge based on what I’ve seen and who I’ve met.
The fact that he’s promoting a specific winter rating tells you enough.
Engineers have said rod bearing clearance, connecting rod side clearance and 60 weight oil was the problem.
It has to do with the rod bearing clearance and rod side clearance wasn’t enough for a 60 weight oil.
You could put 0W-30 unicorn tears in S65 and S85 and they will still wear the bearings. If the engineers said it was a problem why didn’t they change the oil spec ever? They changed to the 10W-60 in a matter of two months in 2001 with S54. Many owners and engine builders have run lower viscosity oils and there’s been no cases showing any benefit. A friend of mine ran M1 0W-40 in one for a while and his bearings still looked trashed when he changed them.
Are you a BMW tech or are you a forum reader?
I’m not a tech. I actually know things.
I love when people think they read all these car forums and they try to come in to the dealer and tell us what the problem is.
You THINK you know, but the fact is you really don’t. I know what the problems are as they are talked about with engineers that come to the dealership and give the input
You better do a little homework and get into the nitty gritty on BMW M5 and M3 rod bearing failures with 10w60 oil.
You mean when I had to take my S55 in to get exhaust cam ticking fixed and explain to the master tech 4 times that the issue is loose exhaust cam ledge bolts when he insisted on replacing the lifters because that worked in the past? I even gave them videos showing the exact issue. Not exactly rocket scientists.
Then why didn’t you fix it bud if you knew what it was. You brought it to the pros BC you didn’t know. See we laugh at people like you that send us a car and tell us what’s wrong with it. Then why did you bring it in.
No, I brought it in because it’s under warranty and I’m not paying for an exhaust camshaft or cam carrier if there was excessive wear present on R&I.
Time is more valuable than money.
Now you’re just pulling stuff out of nowhere.
Wait. Now it isn’t “enough”?? I thought you said the 60-grade was the cause of the problem?
Yeah, that too. I’m not trying to put down techs because it’s a different skill set. I would rather have an experienced tech tear down my engine than a person who hasn’t done it before. That doesn’t mean I trust their troubleshooting or failure mode analysis skills.
