As an update to a previous posting, I've just changed the oil and decided to use Walmart's TECH 2000 SAE 40. To verify that it meets the 6V92TA requirements, I found the certification license at http://eolcs.api.org/DisplayLicenseInfo.asp?LicenseNo%3D0791
. It is listed as CF-2 (formerly CD-II), so I am comfortable with this decision -- except that the ash content remains a mystery.
Now we can wander into any Walmart and find the right oil anywhere in Canada, without worrying about mixing grades or brands. For US journeys, we'll have to bring a pail or two, I guess, since it seems to be a Walmart Canada thing only.
Folks in the border states might want to grab some on a visit North. We paid $32.60 ea. (CDN) for a couple of 20 liter pails (about 5.28 US gallons), leaving over half a pail after the change.
It's nice to get some maintenance work done, so we can focus on the conversion and some travel plans for the warmer seasons.
Update: fixed flaky link (I hope).
Update 2: Darn, it worked yesterday.
