Putting Mobil 1 Extended Performance to the test...

9.xx a quart, and 13.xx for the filter. Call it 55 bucks after tax.

Let’s compare that to a normal oil change…

4.xx a quart, and 3.xx for the filter. Call it 24 bucks.

So, considering that I run ‘normal’ oil in the car for 5000 miles, and if I can run the Mobil 15000 miles, it’ll save money. Of course, that leaves the question of how far can you run the ‘normal’ oil. Even if you’re breaking even on cost, it’s cutting your workload/disposal in half.
