you can not "cancel out" so-called "overages" with your fees to result in less income. On the Schedule C therre is a place for revenue (think of that as the fees you receive for performing a shop). There is another place for Expenses. Expenses are costs which are mandatory. You are required to buy $6 of gas and get a full reimbursement at $3 per gallon or $6, plus a $5 fee for performing the shop. IMHO, the best way to treat this case is to enter $11 as Revenue and $6 as Expenses. Of course, you can deduct mileage associate with the shop, and that eventually gets deducted as an expense at $0.575 per mile.
Now, let assume that you buy 4 gallons of gas. Only 2 gallons is an expense. The other 2 gallons never appears on your income tax except indirectly as part of the mileage deduction.
Now, let assume that you are REQUIRED to go into the convenience store and make a purchase for $1 and get a receipt. The MSC says that they will not reimburse the $1. The $1 is entered on your Income Tax as an expense because it was a required business expense.
Now a "gray" area. You are REQUIRED to go into the convenience store and make a purchase for $1 and get a receipt. The MSC says that they WILL reimburse the $1. You look around, and the least expensive items cost $1.19. The $1 is entered on your Income Tax as an expense because it was a required business expense, and the $1 reimbursement is entered as revenue. The gray area is the left-over $0.19 and dealing with that depends upon your ability to convince the IRS that it was a required business expenses if you get audited. Your ability to convince the IRS that there were no items available at less cost (regardless of their attractiveness to you) diminishes as the amount of money you spend goes up. I would not want to try to justify a $5 purchase. I am willing to try to justify my excess $0.19 on the $1.19 purchase.
To address your question directly,
" I get two gallons of premium gas (required for my vehicle) and end up being $2 over the reimbursement limit, say the shop fee was $10. Would it be reasonable to say my reportable income for this shop would be $8?"
I hope you now understand that the answer is no. IF they say that they will reimburse you for up to 2 gallons of gas up to a limit of $6 and you were only able to buy 1.75 gallons of gas (because you bought the premium grade), then no one forced you to buy more than 1.75 gallons of gas. Any of the extra gas that you bought and which was used doing mystery shopping will eventually be included in the $0.575 per mile rate.
If you had huge amounts of reimbursed gasoline, then the IRS might allege that you are not entitled to the full $0.575 per mile because you never paid for gas, but I doubt that anyone gets reimbursed for enough gas (compared to the total amount purchased in a year) to raise this issue.

Thanks @SteveSoCal and @bgriffin!
I'm surprised to learn that only reimbursed expenses can be considered an "official expense". I guess I'll take a closer look (pun unintended) at the reimbursement amounts to make sure I only take ones where I'm sure I'll be fully reimbursed, or where the reimbursement amount is generous enough to make any overage worth not being able to claim it.
Great info, thanks again!
Forgive my ignorance as I'll get clarification from my accountant on this later, but is it 'wrong' to cancel out my reasonable overage from the reimbursement with the shop fee, then count the 'net' shop fee as how much I made on the shop?
In other words, I get two gallons of premium gas (required for my vehicle) and end up being $2 over the reimbursement limit, say the shop fee was $10. Would it be reasonable to say my reportable income for this shop would be $8?
