2003 Toyota Corolla; Mixed driving, sometimes lots of highway. Other times I drive a good amount of city + idling (I use the car for courier work).
I'll break it down by last three oils/conditions.
MC5000+MMO: 35.5. Summer use, A/C on constantly, mostly Shell 87, sometimes QT 87. Best of the summer/AC use MPG. Highest MPG- 36.4.
Pennzoil Platinum: 34.5. Same conditions as above. Best MPG- 36.2
Schaeffer's 9000: 37.3. Hardly using A/C. Also added 5 ounces Lubegard Red to the transmission. Best MPG- 46.6!
I'm very pleased with the MPG of this car. I think the rating is 26/38(not positive). The lowest MPG I've ever gotten was 30.57
I don't have a lot of data on the Fusion like the Corolla, but I'm pleased with it as well. Best MPG- 33.4. Worst MPG- 23.5. When I was using it for work, I was averaging around 27. Same conditions as the Corolla, A/C on constantly.
Also, I don't drive the cars real hard, most shifts under 3K RPM, around 70 on the highway.
