JD STX38 - low oil after 15 minutes
A few weeks ago my JD STX38 started cutting off after 15 minutes and will not start until about an hour and a half later. What is weird is that after it cuts off, the oil level shows very low. I thought that I was getting oil into the combustion chamber, but it's not smoking, I don't have to add oil regularly, and the spark plug is not getting fouled. I assume that the engine has a low oil shutoff as that is what it appears to be doing. Where else could the oil be going?
