Just returned from the National Mahindra Dealer Meeting and have this to share:
You should be using an additive in your diesel fuel tractor to remove water. Water builds up in all diesel and will damage injectors, injector pump and fuel system parts.
Bosch which furnishes all Mahindra tractor injector pumps will not warranty the pumps of any age if they are damaged by water!
We sell two types on our shopping cart but a bottle of one will treat 100 gals. where as the Mahindra bottle will treat 500 gal. This is less than $ .25 a tank to get the protection.
