Sporting a 44.3-cubic inch motor that creates 3350 revolutions per moment, the X320 is among John Deere’s larger riding lawn for example in San Diego tractors. Offered in cutting widths of 42 or 48 inches, the John Deere X320 scoots up at around 6.2 mph. The X320 employs regular, low-octane, unleaded fuel.
87 Octane
The John Deere X320 manual suggests you use regular, 87 octane unleaded fuel. This is actually the gas you buy at most gas stations labeled as “regular.” Exxon explains 89 octane as a mid-grade fuel, and 91 to 93 octane gasoline as premium. You will likely not see a performance boost in a John Deere X320 by using higher octane fuels, which usually be more expensive.
