Is anyone using 15W-40 in your ZD? Dealer says it's ok. Book says 30, 10W30 or 10W-40. What'cha think?

I DON'T HAVE A 326...that being said. I would think that as long as you are within you manual recommendations, I think you would be fine. I always look at the required rating first, I'm sure it's got to be at least an SH or SJ at a minimum.

As far as the dealer, I would double check what they say, mine tried to sell me an SG rated oil when the manual requires higher.

WELL WHAT DO YOU HAVE.?

ZD326 was one of the options you gave.
 
Pecan, I found the 5w-30 in my Intek does sneak by a little so you need to check frequently to maintain level. But thinner oil will cool better.
