Recently, my 96 D1 (100K) starting running rough on the highway. I'm a little paranoid on which gas I use, so I will say that I normally use Chevron mid-grade. But on this particular day, I was on empty and there wasn't a Chevron nearby. So I put in Mobil's mid-grade. About 50 miles later, my engine began running very roughly. The next morning, the engine stalled a dozen times. When my tank ran dry I filled up with Chevron premium, and then installed some new spark plugs just in case this was the issue. All was well. The truck was running great. The morning after this, my D1 stalled again. It was 50-degrees outside temp, if you need to know. Then later in the morning, I started again and there was no stalls. But the engine still seems to be running a little rough. Any ideas on how and what this might be? Thanks, dean | ||

Sounds like you got some water in the fuel. Most service station tanks have some that sits at the bottom (being more dense than gasoline). Sea Foam (NAPA) is a fuel drier and cleans the fuel system too. | ||

I know people are quick to blame "bad gas." We find that "bad gas" is a wrong guess much of the time. But it's possible. If you suspect bad gas the first action should be to remove your fuel filter and empty it into a glass, watching for water droplets. If you see much water the tank should be drained and the lines and fuel rail cleared. If not, fit a new filter and no harm done. | ||

I suspected gasoline quality since this was the only variation from normal. What do you think this might be? I would be grateful for your help. Thanks, dean |
