Exaust Smell?
 

Hey guys and gals! I own a 08 f150 and have about 1000 miles on it and notice a rotten egg smell from the exaust. More noticable during a period of 50 mph drives and then stopping. I know this smell is from the cats but is this just a normal thing for these trucks?

I remember in the 80's-early 90's a lot of gas vehicles smelling like that. Long time since I have smelt that but ever once in a while I do.

Did it just start?

Did you fill up from a different gas station?

I had it once at about 2k it was there for a couple of days then gone.

If it keeps it up take it back to the dealer.

Isn't that smell from sulfur in the fuel? Lars! You remember the same thing I do! I got it in gas from a Chevron station back then. I stopped using Chevron when that happened and I still feel "queasy" every time I'm sort of "forced" to fill up at a Chevron station on trips, because my tank is low and that's what's available.

About a week ago, we were driving back from a trip with our grandchildren and I smelled it again. Once we all figured out it wasn't one of us, :hehe: I decided it had to be sulfur laden fuel again.

My 05 and my 08 both stink to high heaven...My cousins 08 does it as well so i figure its either the local fuel or just the trucks...

I'll try filling up at a different station next fillup and see if it helps.

That one time I did fill up was at a mom+pop station that had an indepent hauler. Usually I fill up now at the name brand ones only.

Yes Jack sulfur is that smell.

Hmm, i live in a town of about a million people...not too many mom and pop stations and it still smells really really bad...On the other hand, 8 out of 10 times i fill up at walmart/sams...cause they are usually 6-10 cents cheaper and that adds up when im putting 27 gallons in...Thank god i didnt get the 36 gallon tank.

I don't think the sulfur content is really a function of the brand of gas. As far as I know, it's not a "regulated" substance, so refineries don't have to go to the expense of removing it. It's present in crude oil, except "light, sweet" crude, which comes from Saudi Arabia, is supposed to be very low in sulfur.

I suspect any brand you buy could be high in sulfur at any given time.

- Jack

So the sulfer content is all dependent on which refinery and where they are getting the oil from to be processed. Not to argue with Jack but sulfer is regulated in diesel so it must be too in gas. Probably not as much in gas.
