Really?
So Caterham called their tech line inquiring about mixing oils and their tech said it was absolutely fine.
So which is it.
And redline not only says it's fine they even recommend it so a person can fine tune the viscometrics for a specific application.
So I guess I should expect my clean engines to sludge up now,or suffer some form of lubrication failure.

I suggest taking that q&a from mobil with a grain of salt. They are of course trying to sell THEIR product and of course will discourage any thoughts of mixing their superior product with another brand.
And you are aware that in order to carry an API starburst the lubricant must be miscible with other branded api starburst lubricants,aren't you?
Tig why don't you dig up one of the many frankenbrew uoa posted in the forum and prove that mixing is bad.
A uoa is proof positive that mixing is bad,right?
I'll save you the trouble.
Not a single uoa posted here of a frankenbrew showed any problems whatsoever. In fact in the many examples here of a frankenbrew wear metals tended to be lower than the universal averages(not that it in itself means much)and I've never seen a uoa that showed anything even close to abnormal.
So since the api mandates that to carry their star an oil has to mix safely with other brands,and since I mix different brands at almost every oil change and my engines internals are spotless,and since every frankenbrew uoa posted in this fine forum says no problem I'm gonna call bovine carp here.
I saw a quote yesterday from a mobil rep yesterday that states under no uncertain terms that the word synthetic as it applies to oil is a marketing term,so should we then conclude that mobil oils basestocks reflect that statement or......
Back off big guy, you're on a rant again.
