Time to do an oil/filter change on the DRZ400 and wonder if I should
go with semi synthetic or just normal SAE10-40. Manual recommends
10-40 and makes no mention of anything synthetic. Are there pros/cons
for either? I use the bike almost strictly in the streets and hardly
any highway use or speeds in excess of 110 km/h (in case this matters)



1st thing on synth, steer clear until the bike is fully broken in.

Then select what type of synthetic carefully, too much of certain
additives, and you'll get a slipping clutch.

I'm not the guru about which synth is best, or what the dangerous
additive package is. I do know mobil1 used to be safe, but now that's
in question.

I was a rotella diesel oil man myself, then they started added bad-for-
wet-clutch friction modifiers to that, so I'm back to castrol 10w40.
