Wrong number? Matter of fact, I called back on a second occasion and asked about using "a Rotella type 5W40 or 15W40, since these are probably the most popular viscosities used world wide". I was again told, quote "definitely not Rotella, or those other competitor viscosities, because those formulations outside North America differ from what we get, for use on Honda generator products." He then went on to say about his reading about the probability of aluminum related, internal corrosive damage, in using these diesel rated type oils. As a side drawback, he mentioned the fuel economy loss that would result, in jumping to a 40 wt oil, from the recommended 10W30.
Now I did not want to upset the guy any more than I already did. Here is your homework assignment: You call their customer relations help line number - and report back what your ears hear.
