Poor MPG on 92 Camry V6

Due to the old age of the engine I would guess that would be the problem. You can try and run some seafoam through the engine to see if that helps.

When did it last have a tune-up, including plugs, wires, cap, rotor, and air filter?

I'd test the basics first, the rings and valves. to do this a quick way is to just do a compression check. I know reaching the back cylinders is tough - i'm lazy so i might just check the 3 front easy ones first. If these were strong (over 200 psi reading would be considered strong) then and only then would i test the back ones - but if the front ones are low on compression you have your answer.

^ haha, and that sums it up. :thumbup:

I get about 19-23 mpg in my 1994 V6. Gas hogs.

Am I like the ONLY person that has managed to get over 30mpg in a Gen 3 V6 Auto?????

I think I was the first person do hit 28mpg all-highway on a 3vz-fe that posted on the net about it. And I was heavily modified at the time...
Even the vvt trickeration v6's. If you can get 29mpg+ on the Camry platform. You're doing something uncommon if it's consistantly like that on the highway.

My 30.1MPG was figured out well.

Filled up at a CERTAIN pump near my college, till it clicked off, then squeezed 1 more time till it clicked. Only used the CC so I knew the EXACT amount put it, and therefor, the amount put in after that did not have to be the same. Drove 960 miles, 60 miles hardcore City driving, and 900 with prolly an average speed of 75, with Windows down, or AC on on for 1/2+ the time.

Best since then I have gotten when actually calculating it was 28, but that was because I got caught in some traffic.

My best is ~34.5mpg round trip. I'm wondering if I can break 40mpg with synthetic oils and the coolant temp sensor mod...

Like driving really slow. I get passed by semis all the time... :lol:
I'm averaging 30+, with ~1/4 city and 3/4 highway over 5,000 miles, ~50mph average speed. Which is way up from my ~20mpg driving like every other person on the road ~65mph average speed. Saved ~$150 over the last four months, it's like removing one utility bill a month. :whatwhat:

Yeah well my Civic can get like 50-60mpg+ at like 40-45mph! :lol: I'd rather get 35-40mpg & drive alittle faster myself. I do admit tho. I am slightly more prone to drive alittle slower tho. Those tiny tires just don't grip that well.
Eh, most of us like driving at, or above the speed limit & keeping pace with traffic, or slightly pulling away. That means you're going to drop it down.
Really. I never noticed much of a differance on mine when it comes to lots of accelleration VS medium if you cruise at the same speeds. Just never dropped that much.

What you really get into when you're driving faster & loosing a mpg, or two. Is that guess what? Paying that extra $2-3 at the pump is a very, very small price to pay. Even in the long run! Sorta like asking what would be more cost effective. Importing a nice diesel out of Europe that could probably get 50mpg+, or buying an old crappy civic for a couple hundred bucks & getting 35mpg+ out of it.

I went the cheap VW route, got a diesel and gasser for $500! :thumbup: So far the best out of my POS diesel was [email protected], but with a tune up, new tires, leaky injector fixed, and the nice gasser body/alignment I'm hoping to break into [email protected], or [email protected], maybe more with aero crap (like the underbody panel on your Lexus iirc)... I don't mind going slow in light traffic at 4-6am because there's no worries, hassles, or assholes up mah butt, just kick back and listen to music. But if I'm going to Vegas on a Friday I'll set the cruise at 70-80mph. Can't wait till I get a W/VO source and system in.

In terms of price, it really depends. Over the 70k miles I've had the car, I could've saved enough to buy another one in o.k. condition (~$3k) just by averaging 30mpg instead of 20mpg. It's small on a daily basis, but it adds up to a lot, especially on used cars. Kinda like insulation, a wood stove, and evaporative cooler instead of central air/AC and crappy insulation.

The main thing is replace the two main oxygen sensors. Generic ones are about $30 a pop. Cheeeeeeeeap.
Replace the spark plugs, dizzy cap & rotor, air filter, PCV valve.
Reset the ECU by pulling the EFI fuse a second & putting it back in.

You can also adjust the base timing & AFM cog. Which you should do anyway... It's free power.
You're not far off. Especially if you drive hard.

You oughta get about 24-25mpg highway max. 20-22mpg city max. You should average 23-24mpg.




The correct tire pressure to run would be 32psi all around, or 38psi all around.

In South Africa the Gen 3 came out with the 3s-fe, would i still be able to do the above?
Where about are the oxygen sensors? Would it be picked up by the ECU if its faulty?
How does one reset the ECU? Which fuse is it?

Apologies for the 101 questions....i have been looking for info like this on South african sites, but not many people appreciate the camry in SA.

Also, how badly were your consumptions affected when changing from standard rims and tyres to 17" or 18", in my case i have 225/45/17. Its not a lightweight rim, but sure not on the actual weight

I owned a 92 camry v6 until about half a year ago, so I pulled out that little piece of paper dealers put in the windows of new cars listing their features and also in big black bold letters fuel economy. This camry was bought straight from a toyota dealer back when it was new, and the piece of paper shows an estimated 18city 22highway. Obviously with mods you can get much better than that, but if you haven't modded anything to affect fuel economy, normal wear and tear on an engine will decrease that originally estimated amount.

Did anyone notice a difference in Mileage after putting on Aftermarket Rims?:whatthe:

if you put heavier wheels on then yes it will suck your mileage dry.

You could also replace the entire chassis with fiberglass
