2009 BMW E63 M6, Sapphire Black
37K is from 2009, 85K is from 2004 so I guess age could be a factor. interesting non-the-less
Ahh ok. That adds a bit more context. Sorry, didn’t mean to imply the 87k one was clogged, it was just a related thought and a good reason to be proactive on changing them. Unfortunately I seem to recall they’re a fairly significant ball ache to replace on the e60.I've had the 85K since it was a baby, with 20K on it. It does a lot of garage time between drives, but the gas has been good. The 37K I've only had since 34K, so don't know about its fuel history. Ethanol pretty hard to get away from in these parts. The 85K filter didn't "feel" clogged, I changed it for preventive maintenance, car was running great. But it is 5 years older.
