I want to put Amsoil Full Synthetic in my 2004 Cobra, but I cant decide what viscosity to go with. I live in Georgia so right now its in the 40-50, but in the summer it gets easily in the high 80s, sometimes in the 100s, rarely! Im looking at the XL 5W-20, XL 5W-30, ASL 5W-20, and the Signature Series 0W-30. I just want the best for my bone stock cobra with 31,000 miles on it. Any input please!

You cant go wrong with any of those... as long as the oil isnt low you'll be fine

I run Mobil 1 5W-30 with a Motorcraft filter. I'm thinking I will use Aimsoil 5W-30 on my next oil change.

Surely any of the ones you're considering will work fine. I wouldn't stress over it. I would just pick one and call it a day. I used Amsoill for a spell. 5W-30.

Amsoil is good stuff !! For s stock Terminator 7 QT's 5w-20 is fine, I run 5w-30 in mine hoping it will help with the extra boost/heat.............
