bschelle Posted July 26, 2008 Report Share Posted July 26, 2008 I found this and was wondering if anybody else has tried it! "GM has just issued a TSB on this problem that applies to ALL GM vehicles and blames the high incidence of sending unit failures on high levels of sulfur in gasoline. The sulfur corrodes the sliding resistor mechanism and produces erratic and inaccurate gauge readings. To address this problem, GM has released a FUEL TANK ADDITIVE. According to GM TSB #06-00-89-07BB, you should purchase a bottle of GM Fuel System Treatment Plus (part #88861011 for GM brand, 88861013 for AC Delco brand, and 88861012 in Canada) and add it to your tank at every oil change. The additive cleans the sulfur corrosion from the sending unit and prevents new corrosion by laying down a protective film. The additive also removes engine deposits."

Hey, thanks for this information. While she has more serious problems, , my x's gas gage in her 02 Monte Carlo is on the fritz reading full then empty, she has been adding gas every 250 miles It has a hatch in the trunk to get the pump out, I was going to check the connections, maybe this is where I will start instead.

Bruce Nunnally Posted July 26, 2008 Report Share Posted July 26, 2008 While I appreciate that this is one solution, I would suggest that GM needs to design an fuel tank sensor that works in the type of fuel that we have.

JohnnyG Posted July 31, 2008 Report Share Posted July 31, 2008 While I appreciate that this is one solution, I would suggest that GM needs to design an fuel tank sensor that works in the type of fuel that we have. I see that you remember my posts from several years ago. Though I do feel vindicated somewhat in my responses of that time, it is important to note that much of this high sulfur stuff is now gone from the US market. I think we're avoiding it on the open market, (it was generally foreign refined anyway) so it is probably going to China. I seriously doubt that GM is going to supply gold plated fuel sending units anytime soon. Never underestimate the amount of a persons greed.

BodybyFisher Posted July 31, 2008 Report Share Posted July 31, 2008 Is there a way to find out what this stuff is, can I use Techron to solve the problem or is this something special?

bschelle Posted July 31, 2008 Author Report Share Posted July 31, 2008 I read where Techron is the same stuff. I got a couple bottles at Walmart and I just put the first one in my 99 Deville with the gauge problem for about 3 years now. I will let you know how I do!

JohnnyG Posted July 31, 2008 Report Share Posted July 31, 2008 No, the corrosive component of the gasoline can be detected by a "silver strip" test. This is kind of a litmus test and really doesn't yield quantitative results, but it does indicate a problem. The extent of the problem then can be determined in a lab, then treated in bulk storage by certain chemicals in the proper amounts. I'm no authority on the treatment, but Techron is not designed to inhibit, let alone treat, the corosivity of gasoline. I didn't realize that anyone was having an ongoing issue with gas tank sensor failures. In fact, I would assume that this TSB was released some time ago. Can anybody tell me when this was actually issued? Anyway, treatment for this issue should be confined to the GM additive recommended in the TSB, and at the recommended schedule. And definitely stay away from adding copious amounts of WalMart version Techron for any problem. Never underestimate the amount of a persons greed.

BodybyFisher Posted July 31, 2008 Report Share Posted July 31, 2008 My fuel gage is erratic, reading low when I first start and higher the more I drive.

JohnnyG Posted August 2, 2008 Report Share Posted August 2, 2008 So BBF, when did this issue start? You still might be getting some imported (corrosive) gasoline on the east coast. Think of the GM additive as a form of TarnX, not that I would recommend putting THAT in your fuel tank! Never underestimate the amount of a persons greed.

I am going to try this and see if it helps. It would be great to have a gage that is somewhat accurate.

thu Posted August 3, 2008 Report Share Posted August 3, 2008 BMWs had a huge problem with high levels of sulfur in the NE part of the US. They had to fix/replace a bunch of new engines because of it. The nickel coating Nikasil on the cylinders (which makes the surface VERY hard) was destroyed by this high-sulfur fuel. http://www.e31faq.com/default.aspx?ToDo=vi...01&catId=97 Note in that article towards the bottom, that the current 4.4L V-8s have their cylinders crosshatched - just like the Northstar. Also, more info on that same problem: http://www.koalamotorsport.com/tech/article-m60v8.asp 2003 Seville STS 43k miles with the Bose Sound, Navigation System, HID Headlamps, and MagneRide 1993 DeVille.

Texas Jim Posted August 3, 2008 Report Share Posted August 3, 2008 Reckon it is not just our Cadillacs... There is a poll on the GM-Trucks.com board, where some of them are having the same problem that is being talked about here. Per the poll... 40 percent are having issues. But so far...it is a small poll. If anyone is interested.... http://www.gm-trucks.com/forums/index.php?showtopic=82092 Hope this link works.

They had to fix/replace a bunch of new engines because of it. The nickel coating Nikasil on the cylinders (which makes the surface VERY hard) was destroyed by this high-sulfur fuel. I think more than a few Mercedes engines were destroyed by this as well! Thanks T Jim for pointing out that this is NOT a GM problem. The standard of the industry is a silver plated/silver compound resistance wire as the main part of the fuel level sending unit, a wiper on a float changes the resistance much like a volume control knob controls the sound level of a radio. We all know what happens when a volume control gets dirty. So all we are talking about is a dirty surface on the resistor, which can be cleaned up (hopefully) with the addition of the GM additive. The left coast, I know the midwest, and probably most of US refined products have gone to ultra low sulfur gasoline, mostly as a reduction in a known pollutant. Sulfur has an affinity for silver and apparently nickle. Generally it causes the familiar tarnish that most of us have seen on silver, but under high temps and the by-products of combustion, who knows what kind of havoc it could cause. The reason I reference gold plating in some of my previous posts is that that metal is virtually corrosion proof........so Lexus (maybe not all models) fuel level sending unit uses a gold plated wire for their resistor, and wiper. Has any other car maker come out with an additive for this problem? Never underestimate the amount of a persons greed. Link to comment Share on other sites More sharing options...

bschelle Posted August 16, 2008 Author Report Share Posted August 16, 2008 After 1 can of Techron to a full tank of gas the gauge is now working properly.

KHE Posted August 17, 2008 Report Share Posted August 17, 2008 The gas gauge in my '96 Seville becomes flakey on a very intermittent basis. When the bulletin was posted, I checked the price of the GM additive and it was almost $30...... The GM EOS that was $9.00 and then discontinued has been reintroduced - it's now $24.....

BodybyFisher Posted August 18, 2008 Report Share Posted August 18, 2008 My gas gage is a mess, I am taking a trip this week, time for Techron. You know what is ironic about this? I used to use Techron, but because the guru was so adament against injector cleaners, I had gotten away from it. I would suppose that its still important to use it with care? What is the concentration of techron in this stuff can that be determined?

JohnnyG Posted August 18, 2008 Report Share Posted August 18, 2008 I asked the exact same question of "Mr. Gasoline" for any of you that have followed the link, but couldn't wait around for an answer. Maybe, when you have some free time, you might ask exactly what the proper method for cleaning fuel tank sending units is, maybe even how it works, and wait for an answer. I'll ask our research group tomorrow to see what they have to say on the subject. Frankly, I'm fairly certain that all gasoline additives contain the same basic kind of chemicals, but I don't know what might make Techron different. I know we don't use Techron for a reason, not that we haven't in the past. Probably trademark rights to the name. You can probably tell that this is bothering me. OK, so NOBODY uses Chevron gasoline and has a problem with his fuel gauge? I kind of doubt that. Never underestimate the amount of a persons greed.

Hi My problem is, the gauge is showing more gas than what is in the tank.Around 12 litres or 3gallons more.This is when the tank is running low.
