Need Advice–Cleanest Fuel Oil Company

Anyone have experience with fuel oil companies in the Twin Ports? We’ve been using a company for the last several years, and when we had our chimney cleaned recently, the guy who did the cleaning pointed out there was a huge build-up of sulfuric acid in the pipe and even inside the furnace. He attributed this to the quality of the fuel oil we have been getting from the company we have been using (a company he says he has heard/noticed other such problems with).

So, my question–anyone have advice on a local company that delivers as clean a fuel oil product as possible?

Thanks
