Can you mix Redline with Nissan ester?
 

So I just used my last 'stealership' oil change about 500 miles ago and I am installing a Z1 25row oil cooler right now in prep for an upcoming track day at Fontana. I have 6 quarts of Redline sitting on my shelf, but don't really want to waste my recent Nissan oil change. Can I add some Redline to the oil cooler during install? Will it work with the Nissan Ester oil? Both are ester based...
And I guess worst case scenario, I can go buy a quart at Nissan.

I'd just buy another qt of Nissan Ester oil. Just not fond of mixing, even if it's ok.

buy a quart, makes the most sense......

Can you? Absolutely yes...you just have a mixture of formulations (and a weak mixture at that). Would I? No considering it should be trivial to pick up a quarter of Nissan as others have mentioned :)

Ok. Yeah, I'll get a new quart from Nissan. Bummer it's Sunday and their parts dept is closed so my car shall sit in pieces for another day or so. Thanks for the replies guys.

Drain it and put Redline in!

Mix it.

people are so anal and paranoid. Yes I am sure it is perfectly fine to do that...
