It's not the heat, studies have been done using water and it turns the turf off color but does not produce a total kill such as oil. The oil covers the plant and cuts off it's ability to get oxygen, that is where the true kill comes from. Vegetable oil helps, but produces nearly the same results as mineral based oils. The only hydraulic oil the will not kill turf, is Enbio oil, that Danny Dacosta sells. I believe that it is being marketed by BASF. I think there may be a video up somewhere on the benefits and change out procedures. A great product if used correctly, and the change over needs to followed 100% to the T. Have a leak, rinse with water, a little discoloration the first day or two, and within a week you have no signs of any leak.
