Reply to "Oil Decision Time."

"Wow, this is a whole lot of churn just to sort out what goes into your grocery-getter.

There is a dirty little aspect no one mentions here (because they may not be aware?) The formulation 'meets the spec', yippee. Pop open the bubbly. Does the batch in the bottle meet it? Are you buying from a company that plays the 'test until you get a pass, then put that on the CofA' game? What are their data handling guidelines for replicate results that are outside of acceptable test precision limits?"

"Since no one I know of gives you batch data unless you buy in bulk, you may be buying a pig in a poke."

"You mean like the Mobil 1 API Certified 5w30 that Exxon said passed the API engine wear tests, yet when BP and Ashland tested the "same" product off the shelf, it failed the API engine wear spec miserably and showed 4 to 8 times more wear than the Castrol and Valvoline products?"

Nice to see you both have oils suggestions.
Oh, wait........... you don't.[/QUOTE]


I guess if you were a little more perceptive, would realize they both do have a suggestion...................that would rethink your final decision about who the "winner is" as you stated earlier. They both know something about oil,you apparently..........don't.

I am not really sure what this thread is about since you have basically answered your own question in your first post. You already have stated that you use GC or M1. What oil decision are you looking change to another brand after all these years!

Why don't you take your own advice,Trajan............and ask BMW! Why ask us!!! What do we Know! BMW IS YODA IN YOUR CASE! SO USE THEIR APPROVED OIL,AND BE DONE WITH IT!

Your Quote...

"Engine makers know more about their engines than anyone. So I'm a big proponent of using mfg approved oil in my engine."

ENOUGH SAID............
