Only had 2 tanks of fuel in it so far, and yeah it comes from a local truck stop that is very high volume. I hadn't been adding anything to it but since the bottle I bought treats 125 gallons I got plenty left for most of the summer. :laughing::laughing: Still love the little Mahindra. A stuck injector is no big deal, I work for an ambulance service and last week they replaced all 8 injectors in my rig and when they started it 2 stuck open within the first 30 minutes. Hey, if anything does go bad I got 59 months left on the warranty....
