[QUOTE="Pascal, post: 294393, member: 13724"]We do zincs at every oil change so I don’t carry them. Away from home I try not to do any maintenance unless it’s needed, always a risk of something going wrong our 2009 C32s have the manual priming pumps, I ve used them a few times to make sure they work but when replacing filters I use the electric priming pumps. A must in my opinion[/QUOTE] My perspective on all zincs...they don't take up a lot of space, they're typically an errand and overpay when you need them, so keep a round or so on board.
