That's great info about the lubricity issues of my oil, that can explain why I smoked a pump two years ago. I had never even heard of an oil pump failing on a burner, ever, until mine did.
I'm looking up oil lubricity additives right now, and it will be a SOP from now on in my tank. The pump was only like $110 and I replaced it myself, but god **** figuring out that it was the problem was a crash course in oil burner functions and components. It was very frustrating.
What brand biocide do you recommend? just doing some quick and dirty research I've seen a few complaints of excess carbon build up from the additives used in a few brands.
The best rated biocide I've found is Biobor biocide and lubricity additive:
Biobor at Amazon
Seems like what I would choose without any advice or knowledge of the additives used. My tank is inside so I don't think I need any temperature protection, I'd appreciate your input!
