My gas gauge acted funny some time ago, (2 years?), anyway, it went away after I filled it up.</P>


Two days ago I filled it again, and it didn't quite act right...it showed about 7/8 full, and then over the next 12 miles slowly worked toward full. It is working OK now. I know that this is a common problem in the C5s, but I'm wondering if anyone has had any luck fixing it. I have been told that the brand of gas makes a difference, but that doesn't seem to matter to me as I'm not loyal to a brand. Here in AZ (recently moved here) they only have 91 octane anyway. <IMG src=smileys/smiley6.gif border="0"></P>

I've heard that Shell gas has an additive that causes the types of issues youmentioned. Ammaco or Chevron are supposed to be better.<IMG src=smileys/smiley1.gif border="0">

 

i am more surprised that there isnt higher octane!

 

Have to tried changing the sening unit in the tank? The 84 has a float connected to it and sometimes it hangs after years of use.</P>

 

You can put water in your tank and the gauge will still show a reading...doesnt have anything to do with the gas...you can replace the gauge if the delay really bothers you but it sounds like its works fine to me.
