Mixing Delo 400 with Chevron Supreme

[MarkC]

This is only for 1000-1500 miles (the second AutoRx cleaning phase) in my Cherokee.
The place I went to get oil from only had 4 quarts of Chevron 10W30, which I usually use, and no Havoline, so I grabbed 2 quarts of Delo 400 15W40. This will be used with AutoRx for the cleaning phase then, back to all Chevron or whatever.

Any detriments to this kind of mixing, which I don't normally do?

Thanks.

No detriments whatsoever. In fact, I did the very same thing and took a short analysis of that mix some time ago:

I would do it in a heartbeat.

I mix 50% 5w20 and 15w40 motor oil the last change. The pennzoil 5w20's have alot of moly and the longlife has alot of zinc and calcium. I figured it should be about a 10w30.
