Changing it regularly with a 30 weight is lightyears ahead of how most OPE is treated.

Pick what you want, as long as it's Xw-30 or SAE30 and has a API certification from sometime in the 1990's onward.

Snowblower gets the old green GC each year. Just changed it out yesterday. Not sure just how much original green I have (M04)...

I've been using PYB straight 30 for decades without issues. When QSGB straight 30 goes on sale, I'll use that as well-it's actually got a strong green tint to it (not that it matters-just reminds me of some older spec oils)

You'll get all kinds of answers. Why? because almost anything will work. Seriously, a small engine will likely run a long, long time on any juice you put in it. Engines that have the correct level and even infrequent changes of oil, will run well for a long life.
My take is as follows:
Best protection: Synthetic with Mobil 1 HM 5w30 and 10w30 as the best. There are a lot of good syns that work fine, if that's your level of cost tolerance. An HDEO syn in the 5w40 is also a fantastic choice.

Fine protection: HDEOs like Rotella or Motorcraft, in either 10w30 or 15w40. You can't go wrong here, strong oils for long life, at a bit less cost.

Completely adequate protection: ST30, or any of the 30wt oils intended for small engines and diesels. These are among the cheapest and protection is super. I like Wolf's Head 30HD. Wolf's head is good oil, $3 a quart and easily available around these parts.

Ditto. Got no proof for or against other than no failures or issues to date.

Was using Wolfs Head HD30but switched to ST HD30. I would use any 10w-30 but those two are spec for most of my mowers. I use 5w-30 my snowblower...usually what remains from an OC from one of my cars in winter.

Never had 4 stroke equipment issues related to oil.

Amsoil ACD 10W-30/30WT. Has no viscosity modifiers at all, is high in zddp for the flat tappet cams, high detergents to keep these hot running small dirty engines clean and is a group IV oil. Best oil I have ever run in these small engines. BTW I do lawn care commercially (my business) for the last 31 years. Been there done that.
