Is there anyone that still fans of 20w50 or is that weight obsolete now. I'm curious of using in my 88 Ford f150 302 in the summer.

No point really unless it's an oil burner. I have literally had that same engine making over 650 hp and used 10w30.

I put 20w50 in a 88 Town Car with the 302. I thought it would blow up when I started it when the engine was cold as it made so much noise. Took it out a few days later and went back to 5w30 and 10w30. All was nice and quiet again.

Why not just be old school and use a 30W?

Nothing wrong with it in the right application. It has never had many fans on this forum, but I've used it on and off over the years in Chevy small blocks

I like skyactivs suggestion of a straight 30 for your 302 as well. I think you'll actually find more people here favor 30 than 20/50.

How cold or hot can straight 30 be used?

I have 12 quarts of 20w50 Castrol motorcycle to try in my Duramax LML next spring.
You can make your own 20W50 by adding SAE 50 to 15W40.

I use more 20W-50 than any other weight.

Having two old British Leyland vehicles around that spec it, plus badly worn rings on the one that gets driven the most by far means that I can easily chew through a lot of the stuff.

Can't remember if that one had the intake with the PCV in a grommet on the back of it like the car engines, but if it does, there's a screen underneath it that gets plugged up and causes oil consumption. The 302 definitely does NOT need 20w-50, I'd run a cheap 15w-40 in it given your location and the fact it is consuming.

It's been stated, both here & in my GM diesel owner's manuals (6.2 ones) that 32F/0C is pretty much the minimum recommended temp for SAE 30 dino, although if a little warm up is allowed & it'll crank fast enough to start, I would go as low as zero to +5F. I've started (worn-out) engines with 20W50 below 0F before with no issues.
