    I was just wondering what engine oil you guys use in your mowers, Just wondering if you use automotive oil or what is best to use.

    Thanks for any help!

    You should use Dino oil for at least the first 100 hours of use on a new machine ... then maybe somewhere around 150 hours I go to full synthetic, manufacturer recommended weight !!

    Full synthetic always, only thing I keep dino around is one machine takes 20w-50 as hydraulic oil,
    another takes a 10w-30 non-detergent motor oil, couple of other odd applications.

    Everything else I run 10w-30 Full synthetic, cars, truck, the equipment, yes, everything else.

    Same here...diesel oil is a severe duty oil and will hold up in air cooled engines

    I have been using Valvoline 30W for years without any issues on my equipment.
