We run several small 4 cycle engines within extended family. As an example, a Makita leaf blower. One thing learned over the years is to unconditionally change the engine oil each month for the VERY SMALL engines. On the Makitas, the quantity is exceedingly small, just 79.8 mL (milliliters) of 10w30.
Additionally, I often drain and add just a little new oil and drain it out immediately, without starting engine. Black carbon re-colors the new oil at such times.
Several of our Makita blowers are going strong at 7 to 8 years with daily use.
