I recently replaced the leaking sump gasket on my 2004-ish Briggs & Stratton 22HP V twin mower engine. It has somewhere around 700 hours of run time. I can’t be 100% sure of the exact number because there was a short gap between noticing when the old hour meter had died and installing the new one. Anyway, when I owned it up to scrape off the old gasket I was amazed at how clean it was inside the crankcase. If it weren’t for the tiny bit of remaining oil it could have been mistaken for one that had just rolled off the line.
It‘s gotten 25 hour oil changes and 50 hour filter changes since it was new, mostly with Traveler brand 30 grade and then Delo 15w-40 for the last couple of years. There were some numbers written inside the crankcase with some sort of marker or paint pen. I was amazed they were still completely legible after all that time being soaked with hot oil. I wish I knew what they used to write them with.
