Is there such a thing as TOO much diesel additive?

[DieselHead]

Ever since I've discovered the magic of 85+ and DFC, I've been adding a half bottle of one of them, plus several ounces (like 6 to 8) of PowerService additive per tank. My question is, is this overkill? I never figured there'd be any harm in over doing it, but I pose the question to you guys anyway. If you tell it isn't harmful, then great, I'll keep doing what I've been doing. If you tell that it IS harmful, then also great, I'll use all that stuff up at a slower rate. Thanks guys!

Well, just because I've been doing the exact same thing as you, it doesn't necessarily mean that it's OK -- I could actually be a complete moron.

But seriously now, I have definitely noticed a significant difference while using this "witches brew", and I don't think that it is psychosomatic. Additionally (just because I can't leave well enough alone ) I have been adding about 4-6 ounces of two-stroke oil to the last two tankfuls. This may be a bit counterproductive from the smoke reduction standpoint but I just wanted to experiment and see if the extra lubrication for the upper end of the injection pump would make any noticeable difference. (I'm becoming a bit suspicious of my IP's health) It's inconclusive at this point.

Considering what some people put their tanks, and/or use as a primary fuel source, I really don't see how this could cause any harm, unless I'm gravely mistaken. There IS "too much of a good thing" when it comes to using Techron - too high of a concentration of it can cause loss of lubrication to the cylinder walls. Additionally, using it more than a couple of times between oil changes is inadvisable as well.

Hi guys-
On kind of a related matter...How do you check the filter at the fuel tank on an 85 300D? I understand it is vulnerable to clogging from algae, etc. Also, where is it exactly?
Tanks!

Ed:

The fuel tank "filter" is a sock screen on the end of the fuel pickup line. Inside the tank You can check it by gently blowing compressed air into the tank via the fuel line. This will (temporarily) clear anything coating the sock. If it won't bubble, it is also corroded. You will need to remove the tank to service it.

Alex:

I've seen instructions to fix gelled fuel that tell one to fill the fuel filter with diesel fuel treatment and crank til it starts, so I don't suppose there is an upper limit on the amount you can put in the tank, at least phyiscally. At $6 a pint, I suppose there a finacial limit!

I only use that much to clean a dirty injection system. For normal use (mostly keeping the fuel from gelling in sudden cold snaps), I use 3 or 4 oz per 15 gal. More doesn't do much that a litte won't do, and it is expensive to use as fuel.....!
