Boss isn't a big name, but they do have the appropriate API certifications and are competitively priced (as you are doubtless aware). There are plenty of other options. The Rotella stuff is readily available at CT or Partsource, of course.
Others have mentioned Delo, but that's a little harder to find competitively priced. Husky/Mohawk truck stops will have it, and Husky/Mohawk is the official distributor in western Canada. The best price I've come across for Delo, however, is from Maxim Truck & Trailer, which has locations in Regina, Saskatoon, and PA.
I've used Mobil Delvac 1 ESP 5w-40 in the winters here, albeit in a gasser,
with good results. They do make a 0w-40 as well. You'll have to go to the distributor for either of those. There is also Mobil Delvac Elite 222 0w30 which may do the trick for you. Petro-Canada also has a wide variety of HDEOs, including a 0w-40 and 5w-40. Coops would also offer several options.
I had a chance to talk to our head mechanic about the UOA's on the boss lube, his words were its not the greatest but it gets the job done. FYI the UOA's
were from our fleet of western stars with cat/ Detroit engines using 300hr OCI's in case anyone was curious.
If an oil is API certified it's as good as any other oil carrying the same certification. The comment about boss lubes from the mechanic is interesting. I assume he has seen multiple uoa from the same engine,otherwise he doesn't have enough info to state it's not the greatest.
1 uoa isn't enough to judge a lube. Too many variables such as operating conditions,wash out from the previous lube,a dirty air filter etc.
I suggest running the oil and at 5000kms have a uoa done including the tbn and don't drain the sump. See what the lab has to say,then adjust your maintenance schedule accordingly.
It's really very hard to judge an oil without at least a few uoa. Once you collect some data you can make a more informed choice.
It could be that the oil has had it by 5000 miles but if the cost is low enough it may be cost effective to do shorter runs with it.
Once you've got data on this oil you can decide if perhaps a more expensive oil that can sustain longer drain intervals may be more cost effective.
I'm in Saskatchewan. We have Co-op stores. They have their own brand of lubricants. They have a heavy duty diesel rated engine oil that comes in a 0w-40 flavour that is advertised as a pure pao group 4 synthetic. It's not very expensive and is easy to aquire here.
