I just picked up a new North Star 13kw gen. It has a Honda GX630 engine. They ship it without oil. Manual says 5w30 synthetic. What oil would you guys suggest? Thanks!
That's odd, because Honda recommends 10w-30 for that engine. If it were me I would use Mobil1 10w-30 High Mileage with 3.5 HTHS viscosity as a bare minimum. In your climate a 15w-40 with HTHS of 3.7 or grater would make even more sense. Skip the 5w-30 unless you think it will need to start at or below 20 F.I just picked up a new North Star 13kw gen.
