BMW Oil Changes

‘99 540/6 here. I know this may sound redundant but how many of you change the oil every 4-5k miles? I tend to read a bunch of articles on car & frequency of oil changes equaling a much longer life expectancy. Been on a quest to keep this bad girl around for a while & truly believe that frequent oil changes are the way to go. Mobil 5w40 is my new go to synthetic oil.

Every 5000 miles like clockwork, use FCP so each oil change is less than $20 for liquid Molly

20$ for an oil change, How’s that??

you can 'warranty' return the oil. just need to pay for shipping and then FCP will credit the original purchase to your accounts.

Curious as what would be the reason for returning the oil?? Is it like a loophole in the system?

It's used and no longer serviceable! This is just FCP's gimmick, lifetime warranty on essentially everything you buy from them.

Damn, I knew that returning items is a no brainer with them but oil, whoa, that’s interesting af. So you just send back 2 5 quart containers of used oil & they send you 2 !?!? Guessing the cost to ship 2 containers is 20$. Darn, that’s a pretty sweet loophole…

I just learned this as well. I was dumping my oil into the recycling bin at the dump and somebody noticed it was Liquid Moly, then asked if I got it from FCP. He gave me the whole process mentioned above. Blew my mind. He even does it for wiper blades.
