Stanadyne Frozen solid

[JCyrbok]

Sending unit

I have used Stanadyne from just about tank one in my truck. I have never had a problem with my FP sending unit in about a year since installation. Maybe I'm luck or its just waiting to take a crap on me after I post this.

I've been using the stanadyne in my truck since new. 20,000 miles later,no problems. I switched to it from the power service in my '99, and after 40,000 miles, no problems either. Have you guys having the problems thought about the fact that you might be getting bad fuel. I always keep a couple of bottles of the stanadyne in the bed of the truck,and even in below zero temps we've had in the past, no problems. I would think that if a reputable diesel injection shop recommends it, than it should work as intended.

Big A,



Yeah I've thought about bad fuel but I always buy my fuel at the Flyin J which goes through huge amounts of diesel each day. Not to say that they couldn't get a bad batch but that coupled with the fact that my FF hasn't clogged on me and the truck runs good has focused my attention elsewhere.

Iv'e been having good luck with the Siloo brand Anti - Gel (and their conditioner for a few years now.

I would get a hold of Stanadyne and see what they have to say. I will keep a closer eye on my truck. Barry G just replaced the fuel sending unit in his truck. I will ask him if he's been using Stanadyne.

Alex,



I contacted Stanadyne about a week ago and they said that they have not seen or heard of any issues using their diesel fuel additive and really didn't care about my problem. I was surprised to hear how pushy they were. Ohh well, not like I was holding them responsible for trying to buy me a new sending unit. I was just inquiring about any issues they may know of.



I still do think they make a good product, I'm just skeptical that it is actually doing the job right. Jamie and I stopped using Stanadyne in her truck about 2 weeks ago and she said that she has picked up another 1. 5 Mpg. Sounds like maybe a bad batch of stanadyne!!!!



I'm trying to find a hand pump so that I can start putting the Almagated into bottles. I should have results here soon.



rblomquist - Almagated is another diesel fuel additive. It had a write up in the TDR magazine a couple of issues back. Apparently it is supposed to be really good. If you would like I can find the info on it so that you an read up on it if you would like.

Yeah that would be great since I've only been a member long enough to see 1 issue of the TDR.



As far as "gunk" on the sending unit, I don't think it's related to just Stanadyne. Mine went south, and back, and south again in conjunction with using mystery oil and then while using PS.

John Deere Fuel Additive = Motor Honey

Can't go wrong with John Deere fuel additive. Been using it since tank #1 & never had any problems. Comes in Winter and Summer formula. "Big Green" doesn't cut any corners.

How much? Does it lubricate the pump?

Take a look at the address on the JD additive. I've haven't looked lately but about five years ago it was the same address that's on the Power Service jug.

This is a link to the info. on John Deere winter formula fuel additive. The summer formula is much thicker so I guess it lubricates a little better.



Sorry guys, you have to have a user name and password to get on the John Deere Parts web site, so I did a little cut and paste/edit.





Winter formula diesel fuel conditioner - 16 oz. $4. 60, 1 gal. $29. 95, & 5 gal. , $154. 95. Summer formula diesel fuel conditioner - 16 oz. $4. 30, 1 gal. $28. 75, 5 gal. $153. 75.



Winter formula should be used when the outside temperature is below 32 degrees F (0 degrees C). It prevents gelling, keeps injectors clean, provides lubricity, and improves engine performance, which results in better fuel economy and lower operating cost.



Features:



# Improves fuel flow in cold temperatures



# Prevents fuel gelling and fuel filter plugging caused by wax and ice



# Improves power and lubrication



# Disperses moisture and prevents ice formation



# Saves money versus blending with #1 diesel



# Inhibits corrosion



# Keeps injectors clean and removes existing deposits



# May be used as a winter additive for the fuel system of diesel cars, trucks, tractors, combines, and marine engines



Part Number Size

TY16230 16 oz.

TY16231 1 gal.

TY25226 5 gal.





Anyhow, I'm not sure if John Deere's is any better than anyone elses..... I use it because I get a very good price on it and it works. I think it works out to be cheaper to use because it is more concentrated. (1/5 oz. per gallon) In most cases, it is hard to beat Wally World's prices.

I have been using the Rottella T with no problems.

Rotella DSA 4 gallons for $33. 00 1oz per 3 gallons. I would love to see some consumers lab analyze all of the brands so we would know which ones are really better based on application. I know Amalgamated did their own analysis and declared themselves the best .

Rotella DFA

Been using Rotella DFA for quite some time now, available at wallyworld, at least the last time I bought a case. Stuff works fine. I imagine all the antigelling compounds are like STP, don't work unless in the correct environment. See -20*F here every winter, no problems since using it. I do use my block heater, set up on an ambient thermostat set at 32*F. The stuff increases cetane as well... Ron

Been using stanadyne performance formula for 140,000 miles. No problems.

 

[Turbo Tim 1]

The quality fuel conditioners are made with polymers that by themselves would gel at 70 degrees farenheight but then solvents are mixed with them to bring the pour point down to somewhere between 0 and -20. When properly mixed most provide excellent cold filter plugging protection. If over-dosed you will have problems though. Another note would be that after a fuel has reached the cloud point, usually about 0 to -5 degrees for a 40% K-1 mix an anti-gel will have a hard time working. Therefore it is important to treat the fuel prior to problems arising. The stuff I use turns to gravy below zero and 4 oz mixed with 1 gallon of straight #2 will thicken to 5w30 at -20 but if mixed to the recommended rate of 1 quart to 250 gallons it works great, protection down below -30 with a 50/50 mixed fuel. I personally wouldn't do much more than double the recommended rate. Just a little fyi

Turbo Tim, That is some good advice. I've been using Stanadyne PF for 100,000 miles now with no problems. But I stay within the recommended "doses" because I know that too much of a good thing is bad for the system. The authorized Bosch shop in Macon recommended the PF to me when I got my 01 and that's the main reason I use it. I'm sure the others work just fine but I can't give testimonials. I've not had the problem with the PF gelling on me in the container and mine stays in the bed tool box where it has seen cold temps but nothing below 0*.

I've been using 8oz of Stanadyne per tank filling from the beginning in my 3500; 17,000 miles later, no problems.



The ol' Chevy plow has been getting its share for the last 2-3 years, runs fine, although doesn't like to start easy when it's really cold

 

[Intelman34]

I had heard stories about Stanadyne additive gelling up in the bottle and never really believed it, but I guess it really is true.



Power Service works great for me though! I was using an additive called Artic Express since it was free, but now I am back to the Power Service and I getting about 1mpg more.

 

[TBrennan]

Somewhere below zero (-5 deg F?) my Standadyne PF was starting to gel in the bottle. I managed to force the 8 oz. into my tank and added a full tank of diesel (which I'm sure blended it well). So far no problems here in NE PA and I've seen it down to -16 F overnight.
