Here's the 2 things that I wonder as regards the older diesels -
1. ULSD. Will those older engines have problems over the long term because of this stuff ? Will ULSD have a nasty effect on the fuel pumps ? I have not heard of any new requirements but what if there's a new and even more stringent requirement in the works ?
2. I just noticed a sticker on the pump at my local Murphy that stated they are now pumping B20 biodiesel. While my truck can take up to 20% biodiesel, what happens WHEN you run B20 in the older diesels.
I'm not for or against older diesels as regards the original question. I would just want to know the answers to the above questions before I got too serious.
