Amen to this. In my mowers I have used 5w-30, straight 30, 15w-40 and 0w-40 (with various mixes due to adding a few ounces to bring to the full line with a different oil). It never seemed to matter in how they ran.
I have noticed more oil consumption from using dino 5w-30, however. Since I always check the oil before I mow, it didn't really matter. But I can see how that could lead to a problem for someone who rarely checks the oil.
My firsthand experience is with older B&S engines, though. I'd be curious to know if Honda engines also consume more 5w-30 than SAE 30, 10w-30 or Xw-40.
