I've had good luck with Biobor.

That's the stuff I almost bought. Do you just pour it in the tank before
filling?

I was buying just before I needed to fill the tank. The print on the Biobor
Jr. bottle was so small that, even with my glasses, I could only make out a
few phrases that looked like, "full protective clothing", "pre mix with
(some quantity) of fuel", etc. It was the latter that really made up my
mind because I didn't have time to arrange the necessary containers and
means of transfer.

The StarTron says that there is absolutely no risk of interaction with other
fuel treatments. (If the PRI people are correct, that's easy to believe.)
I could still try Biobor when I use up the next half tank.

Another question: Does the alge sludge get through the primary filter? I
plan to put a vacuum gauge in my fuel line the next time I open up the fuel
system. However, my secondary filter is downstream of both fuel pumps so I
can't put a gauge on that one unless it was a pressure gauge just before the
filter.
