Nissan Truck

Engine Size:
Trans: Manual

Issue / Question:
My friend asked why her new car doesn’t need 91 octane. She asked because she said her old 1989 Nissan truck would stall if she used 87 octane. Does stalling due to low octane make mechanical sense?

No its usually not a fault of the fuel at lower RPM stall issues. It could be long term use of low octane fuel could have caused some carbon problems with the EGR valve and cause problems the higher octane fuels would help prevent long term.
