SUNOCO TECH CORNER
Sunoco’s Standard, a 110-octane fuel, has basically been around since the ’70s. Think of it as an entry-level race fuel, Sunoco's Santner says, “that can satisfy a pretty sporty performance build.” Define sporty? He figures roughly below these three parameters: a 13:1 compression ratio, a 4-inch piston bore and a 7000 rpm redline.
Leaded fuels are not compatible with catalytic converters and oxygen sensors. Unleaded fuels will be limited to 104 octane.
