Is it just me, or is this gas mileage TOO good?

[GotToyota?]

Alright guys, I know this seems weird and maybe I'm just going crazy, but lately I've been getting about 25/26 MPG overall. This seems abit high to me, especially with what I have:

JDM 7M-GE with 50kish miles
NGK spark plugs/wires
New OEM clutch
New cat/exhaust piping
Royal Purple 10W-30 oil
4.3 open differential
W58 transmission

This is with 89 octane and occasionally getting on it. Am I just crazy here?

I got some low milage NGK R's from Yellow 13 so im gonna install them tomrrow. See if my gas milage will go up!

 

[Yellow 13]

With or without AC?

 

[Insidious Surmiser]

royal purple'll help w/ that too...

With or without AC?

It's on and off, but I only use my A/C when I head to work, which is probably 2-4 days a week. So I don't use it often.

I think my original window sticker said something like 26/30. Probally gone way down from then.

I only got like 13 mpg the last time I checked. I'm changing my O2 sensor tomorrow. Hope that raises my mpg.

That's what I was getting until I got a new cat/exhaust piping and NGK plugs/wires. It really makes a difference apparently.

we used to get about 30 on the highway in the 88.... i can't figure out why the fuck my 89 gets under 10... its pathetic but i cannot figure out why....

sorry this is off topic, but in the picture in your sig, the car looks FUCKING GREAT!

keep it up!

on topic:

last time i checked i got around 21-23 MPG on the highway, thats with the 550/lex mod and a walbro fuel pump with an AFPR.

also, that was pretty spirited driving, i also have an NA LSD so that hurts the gas mileage alot. so your numbers dont seem to be too far off for a healthy motor.

 

[BorHor]

I didn't know LSD's hurt the mpg. I still think my mpg is low even though I drive mostly city.

Thanks for the comments.

BorHor: It's not the LSD that affects it, it's the 4.3 that makes it lower mileage.

Oh ya, LSD have different gearings.

I get mid 20's out of my 89 turbo with spirited driving and 33 on the highway, my only mods are home made 2 1/2" downpipe with both cats removed and a drop in k & n filter. Oh thats imperial mpg not US

 

[Selz202]

NA LSD is also a 4.30... its not unheard of, your car is more efficient than stock and many others have seen those numbers, its all in the way you drive.
