Dont hate on the filter choice too much. My OCIs are super short on this thing and I've cut frams like this open after use on this engine before and never found issues.
2014 Ariens deluxe 28, LCT 254CC. 1st oil change after 1 hour of operation. Plenty of metallic. 20 Oz of motorcraft 5W-30 semi-synthetic, because it's what I had laying around.
2014 Honda 928WAS, drained FF after initial 2hrs of blowing 12+ inches of wet heavy snow. Refilled with AMSoil SS 0W-30. Lot's of metal "paste" viable in the drained oil.
Switched to M1 because it is much cheaper and maybe better. The mower takes only 12oz. Honda oil is just over $4 for 12.6 oz bottle. M1 was on sale for $3.99 a bottle.
2004 Airens Snowblower - Tecumseh 8.5hp:
Out: PO or FF 30w??
In: Maxlife 5w30
oil was in bad shape - looked like thick green pea soup. Warmed it up and changed it a 2nd time. Easier to start now.
2014 Husqvarna lawn mower - Kohler 4.5hp:
Out FF 30w
In: Maxlife 5w30
In: Kohler air filter
My mother's generator with a 14 HP single cylinder OHV engine.
Out and In: Peak conventional 10W-30, 36oz.
Also cleaned and oiled the air filter, sprayed out Havoline conventional 10W-30, soaked in Peak conventional 10W-30.
