Has anyone used Power Service Clear Diesel?
 

I used Power Service Clear Diesel to clean my tank and fuel level sending unit. The result was a smooth fuel needle. the reserve light started working, and the engine ran smoother. The next tank I ran the SeaFoam through the tank resulting in a rougher running engine and the reserve light flickered. Three weeks later I ran Clear Diesel through the tank again, the reserve light is steady when it comes on, and the engine runs more smoothly. I know this is a very limited sample, but wonder what results others have had with Clear Diesel.

I've never seen it before, where did you get it?

I saw it at Atwoods, read the label and decided it would help with my fuel tank sender. I also saw a Power Service product called 911 for gelled fuel.

We have Power Service 911 (red bottle), Cetane Booster + Antigel (white bottle), and Normal Lubricity increaser/cetane booster (gray bottle) I use the stuff in the gray bottle....don't need anti-gel. Its not going to reach -21F or less here. Last winter's coldest of all days was -12F, and I still got my car started. :D And it was only 1 day that cold. A few more below 0, but not -12.

While I'm quite familiar with the PS product line, I've never heard of or seen this juice. I hope it's safe for a mobile environment...

I'll keep my eye out for it, I'd like to give it a try, though I may just pull my sender and clean it out....maybe this weekend! :D

The description you quoted did say "fleet, marine, construction and agricultural applications." I'd say that covers the "mobile environment"! ;)

I've used Power Service for decades in winter use, in our family's diesel MBs and trucks.

Thanks, Shawn. I certainly did see that. This stuff is a tank cleaner and likely more potent than their other products. My concern is freeing up all sorts of junk that will ultimately flow towards the front of the vehicle and start plugging things.

that's why you have two filters. change/clean them as the collect gunk!

Just had a hiccup under load on my wagon that I cured with highway driving and a dose of the gray bottle stuff. Nothing serious, I was starting to diagnose it, and it went away.

I throw a bottle in every once in a while, seems costly to do it regularly. Don't have much of a problem with gelling or water or biobugs.

Of course, now that I said that....:knife:

I throw in 2 ounces of Lucas fuel treatment and four ounces of DK grey bottle at each fill up. not too costly and it does increase my mpg.

I have the white anti-gel for colder weather, but have not had to use it since last January...

I tried the Gray bottle of PS this weekin my 82 300SD. It did make a difference in performance and I believe it increased milage 320 miles and shows 1/4 tank left. The only thing I would worry about cleaning the tank is that if it breaks stuff loose in the tank it may plug up the sock on the fuel pickup. I started having problems a couple of weeks ago. After driving a while I loose power during accelleration. It runs decent at speed on flat land. It runs fine when you first start out. I picked up filters last night and am getting ready to change them. I'm not confident that this will work, and have resigned to the fact that I will be pulling the tank this week, after I run the fuel level down.

Your driving experience does sound like clogged filters. Change the filters and see whether that makes a difference. Before you pull the tank (unless you feel adventurous:knife:) I would check your tank filter screen. You have to get most of the fuel out (I have a 123, not sure where exactly yours is) so you don't have an Exxon Valdez.

Pull the screen and see whether there is anything to see. If not, leave the tank alone. I had such a bad problem that I couldn't maintain highway speeds for long. Nothing at the tank though. Replaced both filters and problem went away. I am guessing a bad tank of fuel. Your filters should be able to resolve tank issues unless you know about some major problem in the tank.

Is the Lucas fuel treatment any good? I have a bottle of it in my trunk but don't use it much, preferring Power Service Diesel Clean instead.
