Fuel brand DOES make a difference. 200 1985Ti

Yep my data now proves it out. These are NOT single sample data points - they are averages over time with two gasoline suppliers in my area. I started this study last fall. The Volvo I used is not known to be the most fuel efficient of the 240 series (1985 245Ti), the driving with each tank was very similar – commuting to work on country roads 35-55 mph, with small amounts of stop and go near each termination of the drive. Oil through most of the time study was Amsoil 10W-30, then the last 5 tanks with Series 2000 20W-50 (there was no noted change in MPG with oil change)

Results:

Unocal 76 = 24.4 MPG

Chevron = 21.7 MPG

The data points are closely rapped around these means….and no I didn’t run the stats, I can tell the difference is significant!!

I know it's not a double blind study, and again I didn't alter my driving style for the fuel (couldn't do that if I wanted to).

Anyone care to explain WHY????????????
