Star Tron Fuel Tank Cleaner - Remove Sludge, Varnish & Other Deposits - Rejuvanate Old, Stale Fuel - Concentrated Formula Works In Gas Tanks & Diesel Tanks

We began to have problems where every 40 miles or so our RV would begin to hiccup and bog down and lose power and acceleration. We put seven different fuel filters in in the course of 5 days. We were concerned we would have to drop the tank and wash it out and possibly replace the fuel pump. On an RV for him we found out that the problem that we might be experiencing would be a lot of varnish plugging up the fuel pump sock. This recommended filling up with cleaner and letting it sit for more than a day I filled up my tank completely and put the proper amount of tank cleaner in and let it sit for five straight days. After that outfitted with three fuel filters I began to drive. The RV ran terrifically for a while but then towards the bottom of the tank began to have similar problems. I refilled. Added more tank cleaner and let it sit for longer. Since then the RV has been driving terrifically with tons of great power and no hesitation or issues. I am planning on storing the RV full of gas and with this cleaner in it to continue to work on any residual varnishes or sediment

Didn't help my diesel at all actually made things worse and had to dump the whole tank and replace all the filters which I run two of. My truck was running before and it actually made it stall out and not start. Do not buy for diesels.

It does nothing in terms of removing sludge and tar as it states though I strictly followed the instructions for use

pour le moment ça fonctionne comme prévu , je verrai dans le temps

Excelente. Llevaba tiempo con atascos y limpieza de inyectores en la caldera de gasóleo. Fue probarlo y no volver a tener esos problemas. No es económico pero vale cada céntimo que cuesta.
