Oil change on snowblower and oil/filter on generator, both last done 2.5 years ago

. Both got warmed up nicely, generator had a 1500W heater on it for some load while running. It was 45F, sunny, not windy outside while doing them. Forecast on the other hand is a bit different with blizzard warning for tomorrow, 50-60mph winds, current prediction is 16-20 inches. It seems to keep getting increased as the day goes.
The generator had 15W-50 in it from last change but when it was 8F, trying to pull start it is just not a thing. It was also fuel diluted some. Fortunately it does not get used very often, as in maybe 3-4 times in last 13 years. I went for a larger filter this time so the 1.25qts that I put back, has it mid way on dipstick level. It only calls for 1qt per the manual.
Snowblower oil was dirty, maybe a bit grey with some sparkles but has been used multiple times since last OCI. I used some of my on hand Mobil 1 5W-30 regular, no alphabet letters for both. Gas cans and vehicles are filled up, food and drink supply all good.
