150 miles to tank... bad?
#21
Lets see, I usually end up putting about 14 gallons in the tank when I fill it up, and at that point I have about 135 miles on the tank all together. So I figure about 150 miles give or take on it. Car seems to be running fine, aside from a rattling at low rpms like around 900-1200 rpm, and the p0137. I have cause to think its' the cats, but am unsure on the matter. In addition, my local dealership wants to charge me 120 bucks for the diagnostic fee, and will only cover the whole repair (cat warranty 8yr/80k) if they deem it neccesary. i.e. I get slammed with the 120$ fee if they don't think i need a new cat. In addition, it's virtually impossible to change my o2 sensors, I've tried, they won't come out, and the cats are in the way.

Yeah, its wierd though in that it looks like the cats on my car are welded on differently than they were in my two old 99 SS's, in that the cats are flipped to prevent access with a crescent wrench.... any tips?

i get over 300 highway and close to 300 and close to it in the city if i keep it down and that's with no cats headers no air no egr and 4.10's
But anyways, yeah 150miles/tank is bad. One time I did that to about 5/8s tank.. so I used 3/8s and I went 150miles.
I usually average around 250miles/tank but I drive mainly city.

The worst Ive ever got on a tank was like 220ish but that was playin around all weekend and my car's an A4. The M6 cars get better mileage but anything bellow 200mpt is just WAY too low.

the 98's have smaller tanks so it changes the miles/tank
even with my cam I get over 200 city and over 340 highway
that error code is the O2 sensor
if the cats are in weird it's probavbly not going to be covered under warantee since someone modded it, I would say just go LT's and new Y-pipe

I think a lot all comes down to how you drive. If I'm conservative, meaning short-shifting, use 6th gear for all speeds above 50, then I get between 250-270 per tank. However, if I play a little, meaning rev out in first and hit hard in second, then it drops to around 190-220 depending on how much playing around I do. Highway cruising for long distance is great in our cars. Everybody should be over 300 for 70mph, 6th gear cruise-control on driving. But, city driving is way different. Stop and go is terrible for fuel economy. Plus, there's always that temptation to hear that LS1!!
