OK, Thanks everyone. So..... I can stick with what I am using. This mower runs for about 250 hours per year. I change the oil at 90-100 hrs of use. Would I be better of using the Rotella 10w30 than the Walmart 10w30 synthetic? I am looking to do the best I can for these engines without getting into the exotic oils for $8+ per quart. Thanks again. BTW, I too have plenty of T6 5w40 on hand for a truck, but that is not the 10w30 the manual calls for.
