That would be a sensible interval, I should think. After you use up your stash, I'd still consider something a little more helpful with respect to viscosity such as a 10w-30 HDEO (or even a synthetic HDEO, should you be able to get it at the same price). If you go that route down the road, don't concern yourself with whether there's SN on the jug, as long as you've got some combination of CJ-4 and/or CK-4 and/or ACEA E7, E9.
I'm looking at what can nurse you those extra 50,000 miles best with a bit of luck and without breaking the bank. That's about the best I can recommend this side of the actual fix.
