Acidity can build up in engine oil and that could be damaging the gaskets. Replacing oil is going to remove that acid build up which could help. However, I have a car that gets 3 oil changes a year over 6 or 7k miles and that still has leaky gaskets. Age and temperature (extremes, high or very low) are the biggest contributors.

Today's oils are so much better. Amsoil use to advertise 25K for oil changes. Last edited by M4CompConv/X7; 04-19-2022 at 08:22 PM.. |

I am puzzled as to why in the UK the oil change interval is ~19k miles or computer says so. We have no yearly change nor a 10k mile one.
Any ideas why so different to USA?? |

Also, a basic "US recommendation" for maintenance has to be good enough for the people who see extremely hot temperatures (e.g. 115F in summer in the south) along with those in extremely cold temperatures (-20F in the northern states and Alaska). You don't have to worry about that in the UK.

What oil are you using there, is it some extended mileage oil? Definitely sounds high.

Just my 0.2 c on old thread. I do 5k changes on all my cars for 2 reasons:
DI engines run dirty on oil; Viscosity seems to degrade with miles even on newer oil formulas; Perhaps Im overthinking this but oil replacement also cleans any shavings and other garbage that is normal result of operating engine. I plan to keep doing this since I dont see any downside to this procedure. Time and money investment is small enough to have it as extra insurance ( I do it myself) |

Same. $200 ish for an oil change and peace of mind is worth every penny. It's not a Prius, it's a high performance car. I'm all for not wasting money but in this case, it's not a waste.

Planning to follow the schedule on my G80 as well, which in my case will amount to annual changes at 3-4k mile intervals. If I drove it more, I'd have no concerns about going 10k. Additionally, this logic doesn't make sense at all. If your engine blows up after 5 years (or whatever) of following the manufacturers' recommended maintenance, what idiot is running out to buy another one? |

The BMW marketing team and executives don't want your engine to last a lifetime. Still, there's a good middle-ground that they agree to based on EPA requirements (extending oil change intervals to reduce waste) and actual testing. The engineers would probably like it if you changed your oil every 5,000 miles, but the EPA doesn't like it so much. |

Every time I do my own own changes (5,000 mile OCI for regular driving and every 2,500 miles if it involves both track and street driving), I reset the CBS using ISTA. |

Sorry, seems to be a NA only mass "paranoia" with frequent oil changes.
In Europe we run 25k KM (or 15k miles) OCI without anybody questioning BMW mechanics advice, and I spoke to different ones including at BMW Welt. Never heard anyone having an issue due to that, either. I ran my m2 with a lot of hard track use on a factory OCI for 5 years and 80k KM. Zero issues. I am sorry but I tend to trust the opinion of BMW techs, both at my dealer and at HQ in München, over forum wisdom on this one. I am confused as to what "cheap insurace" some of you are talking about. Insurance against what exactly? There is nothing measurable you're preventing, rather paying several hundreds per year for no good reason. That money over a few years would be better invested in a good post-warranty insurance. Now THAT is actual insurance 😉 |

Also, we have 5 year full factory warranty here. If this was stupid, BMW would be risking engine issues during that period. Paranoid, I say. The LL oils are fine and work absolutely great. There are scientific articles on that topic. To me, stupid is changing oil every 5k and wasting money you can use for post warranty insurance. P.s. unless you're actually racing the car or tracking heavily i.e. 80% of the miles. That's a whole other regime. |

Well, to be fair I should say we also get 3 years (no KM limit) by default, but extendable to 5 for a grotesque amount of a couple of thousands, which is basically peanuts compared to the benefits it obviously gives you.
