Took a trip up to MI this weekend. Impressive mileage once again.
It was about 20% city (by time) or 10% city (by miles) so let's call it 85% highway, 15% city.
Total of 492.2 miles on the tank; I had about 0.6 gallons left when I filled up. Yeah, cutting it close - anyway... that comes out to 41.8 MPG
. Was running Shell V-Power 93 Octane.
Half the miles were in serious rain and/or a strong headwind and I noticed (watching the MPG meter) both caused a performance hit, as you may expect.
After 11.5K miles and a few long road trips I'm starting to come to the conclusion that I realize a measurable MPG boost on 93 Octane whenever I'm running all/mostly highway. When it's my more-usual 50/50 city highway split, I'm not sure that there's an MPG benefit from running premium.
One final note - MPG meter in car indicated 39.8, actual was 41.8. Pretty much in line with the 5% variation I usually see. What I do find interesting, though, is that the car more often under
estimates when I run premium and over
estimates when I'm running regular.
