Source for Valvoline VR1 10W40?

[Jeff G 78]

I always used VR1 in my race car with great results.  When it was super hot out, I'd run 20W50, but I'd usually run 10W40.  I am trying to buy some now for my street Z and I cannot find it anywhere.  They still sell 10W30 and 20W50 on Amazon, but the 10W40 seems to be gone.  Valvoline's website still shows 10W40 VR1, so it's not discontinued.  When I lived in MI, my local Napa store always carried all viscosities of VR1, but in AZ, I can't find anybody that stocks it at all.  Amazon only has 20W50 and 10W30.  Here in AZ, the Fall/Winter temps range from lows of 30F to highs in the 80's, so I think 10W40 is still the best viscosity.  Should I keep looking, or switch to something else that's easier to find?

It’s out there, saw it a couple of weeks ago somewhere. Let me backtrack a little. Will let you know. Hopefully others will chime in.

Their shopping site doesn't show it.  Seems likely the main site is out of date.

If you blend 10W-30 with 20W-50 do you get 15W-40?  Hmmm....

Fascinating, I checked Rockauto but they didn't have it. I googled it and checked the shopping link. Some 10w-30 and 20w-50 but no 10w-40. There was some straight SAE 40...

Same thing at Jeg's and Summit racing...

I've read that the VR1 10W30 doesn't have as much ZDDP as 10W40. I also read somewhere that they quit making 10W40. I think 20W50 is too heavy for our upcoming temps. I guess 10W30 it is...

I would think mixing different weights of the same make oil would be okay, but not ideal, or convenient.  Here's a handy ZDDP chart if searching for another.  I can't believe what oil costs nowadays!

I don't think you can go wrong with this stuff.
