Hi guys, I'm relatively new to oil and have a question regarding S/ES and H/EH nozzle patterns. I know that the ES/EH are specifically for kerosene but otherwise it appears that an S and ES are interchangeable. This has me wondering if its necessary to carry both, as it seems pointless to be carrying say a 60/60S and 60/60ES on the van if thay are basically interchangeable anyway,
Thanks, John.
