Older classic vehicles use thicker oil , bearing clearances were not a tight as modern vehicles hydraulically lifters were not really a thing, flat tapped cams. Race car drivers also use thicker oil bc it moves slower and provides better coverage in the engine during high reving high heat. When I was a kid had no money a lot of my vehicles leaked/smoked, some oil thicker oil leaks slower burns slower. Lastly many even modern motorcycles still use thicker oil.

Idk I never used a Pokémon . They came out way after my childhood. I own a classic car that requires higher zinc levels more than most modern engine oils .

They are $8.78/quart at https://www.walmart.com/ip/Mobil-...t/20713645
And $24.97/5 quart at https://www.walmart.com/ip/Mobil-...t/20713647 which is a good deal I normally use to purchase.

It works great in air cooled lawnmower engines. Not recommended for freezing temps... but you really aren't mowing your grass in the snow. I guess that would also mean... don't use it in your snowblower.
