MOBIL 1 Synthetic 0W-40 oil FOR A 89 760 (6 CYLINDER) NON TURBO? 700

Hello fellow Volvo gurus!

I have a series of questions regarding oil and oil filters for my 89 760 (6 cylinder). I hear that Amsoil is the best, however Mobil 1 is more readily available. I was considering using Mobil 1 0W-40 for my car in addtion to a Mobil 1 oil filter. What are my advantages over, say using a 0W-30 and or a 5W-30/10W-30? Also does anyone recommend using 15W-40 in the summer months, it can get very hot and humid up here (northeast). I was just concern that 0W-40 may cause my engine to burn more gas? Are the viscosity index numbers too far off? Will the Mobil 1 0W-40 give me more protection? I would be willing to dump it/replace filter every 5,000 miles. I have some oil build up on the top of the motor, possible seals, and or distributor o-ring? And my last question what type of gas mileage could I get out of this V6 motor? The engine is very smooth.

Thank you
