Hey guys just wondering whats your fuel mileage? My 97 V6, 5 speed seems like its getting [shizzle]ty mileage I'm getting about 550km a tank with 91, where my old 93 v6 5 speed used to get about 650 minimum with 91. My car has 219 000kms on it. I've replaced the air filter, done BG induction clean, plugs, wires, cap, rotor, fresh oil with Lucas additive.
Lol that sucks guys, you must be doing lots of driving in traffic. I'm only asking because my 93 got better mileage...I think I figured out the problem, I'm getting minimal activity from the bank 1 sensor 1 o2 sensor as per my air/fuel ratio gauge. Right now im thinking its not getting into closed loop, ill check o2 sensor signals as soon as I'm done work.
I get 24 mpg city, sometimes can get 30 mpg highway on my 94 v6 auto. But lots
of short trips really can cut it down, sometimes can drop to 20 mpg. I use premium.
I always fill up when the light comes on, it takes about 12 gallons from there to fill up.
I see the tank is 15.5 gallons capacity, have never drained it down close to that.
Worried about the fuel filter clogging.
Just bought my 93 MX6 5 spd, body has 355k but I think the engine is at around 200. So far filled up my car 3 times, and getting 23.38 MPG. between the 3 fills. the first two were lots of driving, with no tune up, then did plugs, wires, oil change with lucas, and K&N air filter, just bought new as well. Going on a highway trip tomorrow, will report back with the fuel economy on the highway.
If you have ethanol mandated to be in your gas in your area, you'll never get the mileage you used to get back in the day. Not sure what Canada's take on the ethanol scam we have here in the US is. There's not as much energy in ethanol as there is in gasoline.
Another reason you will notice poor mileage is that in the winter, all gas companies change their formulations so it will burn better at low temperatures. Because of this, it doesn't have the same energy as summer gas.
Back before ethanol, in the same car I drive today, on cross country trips I could consistently get 32-33mpg when in the flat states and maybe 25-30 in the hilly states. Nowadays I can never break 30mpg because all gas has ethanol in it. Performance also isn't as good. God bless our corrupt politicans.
Regarding the lucas additive: totally unnecessary and guaranteed to cause poorer mileage because anything you add to your tank dilutes its total energy. Nothing is as a powerful as gas and it already has all the additives it needs. Use premium, keep on top of your O2 sensors and that's all you can do.
Run a bottle of Techron (not the cheaper bottle, get the expensive one as its a higher concentration) or Gumout Regane through the tank once a year and call it good. Both contain the exact same active ingredient and it is superior to anything currently on the market and is the only chemical that will both clean very very well and *also* not leave a residue of its own behind. Absolutely nothing else is needed. For the most part, Lucas is snake oil, and so is just about every single other product on the shelves. In your neck of the woods, I might imagine a fuel-line drier is sometimes beneficial. THat's all I can think of.
