" I run synthetic, diesel rated oil in it. Changed hot and often"

Atta boy ! .

Oil is the cheapest mechanic there is .

Using fully synthetic oils will in fact allow you to drive the engine clean .

Many years ago I got my son his first mechanic's job in a lawn mower shop, he came home one evening and said " you told me Briggs & Stratton makes good stuff, they use plastic cams and gears, it's all trash designed to fail after a few years of light duty service !" .

Oops .

Kubota makes very good engines yes but after ten years or so they often no longer support parts..... when I was supporting a huge municipal fleet we had to either buy new engines (no, never) or salvage the entire machine due to zero internal engine parts availability .

A shame, what it means to you the owner is : HOT CHANGE THE OIL ON TIME AND ALWAYS A NEW FILTER ! .

Then you'll be amazed at how long it will last .
