Hey Guys, What brand, weight oil are you using in your Kohler gennys? TIA

I use 15w-40 diesel oil. It has the zinc additive that auto oil no loner has. 200+ hours so far.

Mercury 25/40 synthetic blend.

I know that question is a "Grab your popcorn" type question but all my paperwork is on the boat and I'm finally feeling good enough to do some of this SH#@ myself and save the HEAVY lifting for the younger gen...….lol

From memory the Kohler 7.3 manual states a straight weight 30.
