Hi Jason
Thanks for contacting the Answer Army to post your questions.
Always follow the recommendations from the Engine Manual. You should have received a manual from the engine manufacturer. They have the oil requirements listed. However, unless you are running in the winter (snow thrower etc) 30 weight will work fine.
Do not use synthetic unless the engine manufacturer recommends you do so.
Thanks again from the Husqvarna Technical Services Team
I’ve just bought a tc138 and I’ve bought husqvarna oil sae30 and filter, I was told if your not mowing or using it in the cold below 0 sae30 is perfect
