I can't remember when I didn't fill up at some Rotten Robbie or other. The one on Lafayette and Aldo in Santa Clara is a commercial truck stop so they have good product turnover. I had a recent algae problem with the SD. I can't blame it on RR since I fill the SDL there too. Must have been the sitting for weeks with an almost empty tank. One tube of Diesel Doctor and the prefilter is clear again.
