In a car you drive 12 months a year its reccomended every 5 years or 96.000kms now for a sled we use 2 months a year with avg. 5000 kms a year...hummm if its not changed colour still a bright GREEN I wouldn't worry about it...its not a big investement to change it if it makes you feel better, if you do change it I'd go 60/40 mix of a good quality like PRESTON premium brand and use ONLY distilled or de-ionized water you can buy at Canadian Tire for $1.49/3.78L and LET IT SNOW!!!
