I am near Peoria and just got my B2620 last spring/summer. I run only non bio diesel and used the Power Service silver bottle all last year until it got cold and then switched to the white bottle. I haven't had a single problem and I just hit 45hrs this afternoon spreading gravel.
I had to spend over $600 last year, October for a complete fuel system cleaning of L 3800 with only 70 hours on it. Algae was determined to be the cause of tractor sputtering and shutting off during operation. (First season of owning)
With this said, can someone please advise on what they believe is the best additive to use. I keep a 5 gallon diesel container full for use after every time I've used by Kubota. I've placed a picture below on the different additives I've purchased and wanted the opinion of the OTT members. Dealer said that the climate here in Illinois last year...for some reason, caused the Algae to be extra tough on diesel fuel. Thanks.
