Just bought a 1999 Maxima SE. The wife put about 10 gallons of 87 octane when the low fuel light came on. I filled the tank with 93 octane and checked the fuel cap, but the SES light stays on. Had the OBD scanned and came up with O2 sensor and Knock Sensor codes. I authorized the shop to clean the fuel system--they did not say this would clear the SES light--but I went ahead and had it done. There are no drivabilty issues. Could the lower octane trigger the SES light?
