This is just one brand but in searching Shell Rotella Diesel oil, I
see there's 3 different types available here in Canada from a Canadian
vendor.
From canadiantire.ca vendor FAQ re Zinc content:

Rotella T3 15W-40 1325 ppm zinc

Rotella T3 NG 15W-40 800 ppm zinc

Rotella T5 15W-40 1230 ppm zinc

Rotella T5 15W-40 is a semi-synthetic product formulated for heavy
duty diesel engines. Rotella T3 NG 15W-40 is formulated specifically
for use in natural gas fired engines. Rotella T3 15W-40 is the
mainline product for heavy duty diesels."

I'll double check the container, but I'm about certain I recently put
in Rotella T3 15W-40
Regardless, from this Shell PDF page  http://tinyurl.com/ofwcbtr

"· Hard working diesel and Gasoline engines Suitable for use in
pick-up trucks, sport-utility vehicles (SUVs), mini-vans and
motorcycles."
