Ran a liter of 2 cycle outboard tc3 oil to see what the deal is and found the smoke and stink (even with windows up)at stop lights was too much. I like the quieter engine but not for the price of that smell through the vents. Others find the same or just me? Anyway I'm back to power service treatment...stink gone.

I can't tell a difference in odor when I run 2 stroke oil versus when I do not.

I dumped a liter in about 3/4 of a tank and couldn't smell anything different. Even when I was hooking up a trailer with the engine running

I use a quart per tank and can't tell.

Hmmm,
Maybe I'll have to try a different brand 2 cycle.

Use the wal mart stuff.

I use 2-Stroke AMSOIL HP Injector 12oz per full tank...People tell me it smells like a Charcoal BBQ :)

i used the husqvarna premimum 2 stroke oil. no extra smoke or smell
