My recent truck 1983 Scottsdale C10 has 383 SBC, I am going to do an oil change, what oil viscosity would you suggest using it?
The previous just said "high mileage" type.

It would help to know what temps you are dealing with outside in winter and summer and if you are towing with it

10W-30 is the recommended viscosity for that model year. Grab what every brand catches you eye at Walmart.

Castrol 10-30wt. I use it on my ZZ4 in Texas hot weather. In the original 305, Castrol 10-30wt saved the engine twice. Each time it over heated. Once for a busted hose. A second time for a leaking heater core.

THE VIBE ONLY HOLDS 4.5 QTS SO I HAD A .5 QT LEFT OVER FROM ABOUT 2010.I HAD IT IN THE SHEAD & JUST USED IT FOR MAKE UP OIL IN MY PUSH MOWER.I NEEDED A LITTLE OIL IN THE G6 SO I HAD SOME OTHER BRANDS LAYEN AROUND. STARTED PORING THE GTX IN THE FUNNEL,IT WASN'T GOING DOWN 2FAST,I NOTICED A CLEAR GOO CLOGGING THE SS/MESH IN THE FUNNEL,WEIRD !!!I HAVE OTHER NEW OIL STORED IN GLASS JARS,ALL THAT WAS OK,IM WONDERING IF THE PLASTIC DETERIORATED & WAS FLOATING IN THE OIL ?IM PRETTY SURE IT WASN'T WATER.

Good point. I didn't mention I use 1 quart of Lucas oil additive. It replaces one full quart of oil. The additive sticks to parts better after shutdown. Valve ticking on cold starts is almost gone since I've started using oil additive. I use it especially on my '08 Nitro that calls for 5-20wt oil. The light oil caused a lot of rocker arm clatter on morning starts. Now, it rarely clatters and it's really quite when running.

Today's high-quality engine lubricating oils are very sophisticated. Most oils already contain precise amounts of additives blended into the lubricating oil to meet stringent performance requirements. These oils meet performance characteristics that conform to the lubricant industry standards and are sufficient protection when used according to the recommendations. Aftermarket lubricating oil additives are not necessary to enhance engine oil performance and may in some cases reduce the oil's capability to protect the engine.

Dodge engine designs are notorious for ticking. Especially the overhead cams in 3.7 and 4.7 engines. Both use 5-20 wt oil. I drive a 3.7 and fixed a 4.7 for my dad. The lash adjusters lose movement over time. Light oil will not stick to parts. My Nitro engine is a lot quieter using the Lucas additive. Without it, clatter is very loud. I've noticed that oil change mileage increased using Lucas. Straight oil run less miles. On my experience, I'll stick to using a Lucas quart for overhead cam engines.

How do I get this off to put oil in? Do I just pull it out? I tried turning but the metal piece just spins

Pull up on it. It’s two a two prong metal base. The prongs have to squeeze together to clear the opening.

Yes, slowly as there may be a baffle in the valve cover.
