Hi all. I’m looking into buying a little grease gun for a separate project but I’m wondering if anyone has gone around and greased the fitting on their HRV before? I assume there are zerk fitting around the vehicle, but I don’t know if those come in different sizes or if it’s standard size. Also, I see much about psi when searching online; does anyone know if there’s a minimum psi needed to properly grease these fitting? Thanks.
