I know a lot of guys on here run Mobil 1 15w-50 synthetic, me included.
I've seen a lot of guys switching away from M1 since they "changed the formula" or whatever as well. I was wondering if someone could explain exactly what happened and why it was no longer suitable to use.
I've also heard complaints from some BMW shops that Mobil 1 15w-50 is too thin and the additives aren't right which tends to result in a lot of excess valve chatter that is often solved by switching to something different. A couple people on the forum also noted increased valve noise when running M1 in their s14's as well.
Are either of these real reasons for concern? Tons of people swear by M1. I've never run anything different, so I don't have a baseline to compare to. Next time I'll probably try something different just to see if I notice. Just curious.
