Star Tron Fuel Tank Cleaner - Remove Sludge, Varnish & Other Deposits - Rejuvenate Old, Stale Fuel - Concentrated Formula Works In Gas Tanks & Diesel Tanks - 1 GAL (093600)

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

Put in fuel tanks. Pumps seam to work better

This product works very well for what it was designed for

This stuff seemed to do a really good job at breaking up sludge in a gas tank. Didn’t help with any rust

Used one old trucks that had gas left in them for years. It took awhile but it cut through the varnish.

The package arrived quickly and was securely packaged. I have used this product before and really like it. Before using it in every tank of fui my side-by-side would not idle without going dead. I have used this in every tank, according to directions of one ounce to four gallons for the past year. Today I can let it idle forever and the motor doesn't die.

This did not do what I needed to do but I may have been asking too much of it. I looked at some reviews before purchasing and it got high ratings but I think it is more of a fuel additive not a gunked up system cleaner. I was attempting tp clean the fuel tank on a generator that was full of fuel that had gone bad. It absorbed a bunch of moisture and the tank rusted inside. There were a lot of rust chunks and it ended up taking far more drastic measures than this to get it cleaned out. I'll give it a second look if I need to store fuel but it didn't really do what I needed.

Had a trouble code display and was after buying fuel from a station that was having a tank issue. My car was running a little rough so I added this product and let my car set for 24 hours. When I started it, the check engine light turned off and the engine ran smooth. I’m impressed with this product and have recommended to family and friends. No complaints whatsoever.

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.

After draining the fuel tank on my recently purchased 1967 tractor I put in new fuel and added the instructed amount of product . New clear view fuel filters are still showing no debris and the tractor starts and runs well after standing idle for four years .
