Using my real MPG data (27) and adding 3 MPG to get to 30 MPG average and using my average fuel price per gallon, which is $3.24. The N20 would have saved me $2,300. I'd bet anything that by 200,000 miles, I'd need to replace the turbo(s) at some point, which would easily be a $2,300 repair bill, so there is no net gain. Yeah, okay, you can make the argument that the N20 would be a half second quicker to 60 MPH, big deal. I need reliability and longevity. Throw in that the N20 is probably more expensive to produce than the N52 and would raise the base price of the car by a few thousand dollars, there is no benefit at all.
You fill your car up with regular??
