about compression ratio
Searched forum but got no good answer....
I have right now 1.8l 66kw 4cyl engine with compression 9.8:1
if I raise it to 10.5:1 then what about fuel consumptiom?
more economic or less?
I drive usually with octane 98 or sometimes 95.
I have no manual, but I guess manufacturer(renault) suggests 95 (or 91 if 95 is not available)
My typical trip: 85% country roads(+highway) and 15% city
