Neither you nor the truck will ever notice any difference.

Yeah it doesn't make much difference. I switch between 5w20 and 5w30 Royal purple depending on how careful I am when ordering it, and I haven't noticed a difference.

Mobil 1 has a synthetic 5w20, but if you prefer the royal purple 5w30 and its available that works too.

Some synthetic 5w20's like Mobil 1 are actually closer to 0w20. So a 5w30 is a decent choice.

5w-20 is super easy for me to find. Anywhere I go I can get 5w-20, even the local farm supply/hardware store has 5w-20.

The 06' gassers are designed for 5w-30 and thats what should be used. You don't even need a full synthetic, Motorcraft 5w-20 Blend can be gotten at a Dino oil price.
