Very interesting information.
I always get about 70 miles to the gallon on average. I have yet to break 100 miles to change to reserve.
I just purchased a gallon of Rotella 6T for my 2000 mile oil change and I hope I get some results like you on the move from dino to syn.
I'll keep an eye on it.
If anyone is interested (O'Reily aka Kragen) has rotella on sale right now for $17.99 a gallon 6T and 10.99 a gallon for dino. Also Mobil1 Motorcycle and VTwin for $7.99 a quart.
