Honda oil is usually what we use, but if you have to change it
on a Sunday or Monday which most Honda dealerships are closed,
be sure & use one that is not energy conservative. Like last time i
changed mine, it was on a Saturday evening when i sank it. I got
about 10 quarts of el-cheapo motor oil to flush it out, then put some
Valvoline atv oil in. I couldn't get Honda oil because it was too late.
They were already closed.
