You can use sythetic oil after the engine is broken in. The whole thing about american cars is BS. Vette's come stock with synthetic.

Oil: Motorcraft 5W-20 which is a synthetic blend.

Plugs: Motorcraft AGSF-32C which is a copper plug.

I bought 76 Super, Synthetic blend SAE 5W-30 motor oil today. Is that a good oil to use for my -01 GT ?

Ditto. The blends are a bad compromise. Stick with dino juice or go synthetic.

I have already put it in the engine, was that a bad idea?
Will it run badly whit "blend" ?
Is there some difference on 5W-20 and the 5W-30 I put in? It says 5W-20 on the oil cap...

I'm using the Syn Blend Motorcraft 5/20 at least until the warranty runs out (3 years). It's very good motor oil. Stick with the thinner 5/20. As for full synthetic, everyone has an opinion either [positive or negative. The KEY is to change the oil and filter at 2,000 miles (HOT) to remove the acid that builds up from combustion. It's the acid that kills the engines and makes sludge. I've got cars with 100k+ miles and zero sludge just by changing the oil and filter hot every 2,000 miles. Stick with the Motorcraft filter. Auto Zone sells Motorcraft Syn Blend for $1.89/Quart.

I don’t think changing your oil every 2000 miles vs 3000 miles will help sludge. Sludge is usually a result of frequent short trips where the engine never gets up to a normal operating temperature. This causes the water in the engine (a natural result of burning gas) to not reach boiling point to vaporize, which then mixes with the oil and carbon to create sludge, which then gets deposited on engine parts when the engine is shut off.

The key to avoiding sludge is to avoid running the car for very short amounts of time, like driving a block for ice cream, and don't start the car just to move it. If you do, let the car warm up fully before shutting it down.
