So, if it takes 40 dollars to FILL my gas tank each week and next year it takes $40.40 each week then I've lost 40 cents on the value of my transportation asset (the ability to travel 1 tank full of gas when all factors for said trip are considered same like MPG and driving conditions etc.)
The stocks I own are in companies that sell stuff. So they won't decrease in value even though they're valued in dollars?

You bet. The oil company shares I own should keep their value because they can sell the oil for more, right?
