No - no advantage.
Stick with what's recommended and you'll be fine. :)

Subject: DML: Re: Oil weight
Hi Guys,
I looked through a couple of the replies to this thread and came up with a
question. Do you think there would be any advantages to using two different
weights in the pan at the same time?

it turns out that I ended up with 5w30 instead of 10w30 [mobil1]. Given
that it's been gawdauful K-K-Kooooold here lately (subjective) the lighter
oil seemed like a good idea anyway, so I went with it. Which brings me to
my question:
> I have been switching weights with the seasons, 10w30 in the cold,
15w50 in the heat up to this point, and Blackstone has confirmed some facts
for me. The most interesting is that, fresh out of the bottle, the 15w50 is
better oil, in almost every respect. After 6000 miles [hot], the 15w50 was
only showing a little over 1/2 used, and according to Blackstone, could have
been pushed to close to 10k safely. The 10w30 was almost completely used up
after 4500 miles [cold], and should probably have been changed after 4000 or
so. I am assuming that the 5w30 will also suffer this "shorter" lifespan,
but I haven't sent samples in to confirm or deny this.
> As an experement, I also tried delo400 15w40 dino oil for almost

miles. I probably could have gone longer, but it was getting cold, and
15w40 seemed too heavy. I'll post the results of that , and of the 10w30
castrol synthetic blend that I am trying in the bimmer currently, when I get
them. Oh yeah, I had a question.. Do any of you guys that run 10w30 year
round, ALSO send your oil to blackstone for testing? I'd like to see how it
holds up during the summer.
