I may continue using the OEM filters. The main purpose of this thread was to ask about the aftermarket filter that the parts desk sold me and if it is ok to use since I already have it. I may continue buying the OEM filter. I have been changing it at 100 hrs or once per season as it’s not very expensive. I could wait for 200 hrs. Each time I’ve drained the engine oil it is not black or very dirty looking. I think the most important thing to life of OPE is the air filter. Luckily this Toro has the large Donaldson canister setup.If you are going to follow factory recommendations for service, then you only need to change the filter every other oil change (or 200 hours). That cuts the cost in half, so just use the OEM filter.
