How To Read Mileage On A Fox

Interesting. I'm wondering if my stang has 60,000 or 160,000 miles. My pedals show no wear. Just some normal stains from dirty shoes.

The stock torque boxes look great and it still had the stock 2.73 gears along with the aod, so the engine hardly ever saw rpms higher than 2000. This car confuses me. There are signs of high mileage and signs of low mileage. When I took off the valve-covers, there was a lot of hard dried oil glaze (dark brown grime) covering the underside of the valvecovers and inside the oil breather/filler neck and a little grime on the valvesprings. No sludge or carbon though. The inside of the throttlebody and intake manifold was soaked in oil also, due to a clogged PCV filter. The driver side seat also had a busted bolt which caused the seat to lean back all the way down to the back seat. Odometer shows 60,422 miles now, so I put 422 miles in it since I bought it back in july of 2015. lol

sure fire way to find out. send an oil sample out for analysis

The oil glaze and other oil globing, clogging and general stickyness in my opinion is from running the engine for short periods and low rpm schlepping around town, not bring the oil up to temperature and dissipating the moisture from the inside of the motor. I suspect the gear oil in the rear is suspect too. Another reason could be the previous owner used a 'jiffy lube' type establishment to service the vehicle and they used inferior oil products. Cheep oil is just that, cheep, may actually be low milage just poor choice of maintenance products.
Or could be that the pcv system malfunctioned at some point and they didn't notice.

The car had cheap standard oil and a no name oil filter. Probably cheap Jiffy Lube crap. I actually did an oil change on the car myself using Mobil 1 high mileage oil and a motorcraft oil filter, after cleaning up the inside of the intake manifold (changed intake manifold gaskets) and the inside of the valve covers (changed valve cover gaskets also). That's when my dad decided to grab the stock 5.0 HO lower intake that I had laying around (from my 93') and port it himself. I think we killed 10 birds with one stone. lol The gear oil didn't look too good either. Looks like it has never been serviced since it came from the factory. lol Even with the stock 2.73's and an AOD, my car could actually break the tires loose. There's a saying that a stock aod mustang with 2.73's would just bog off the line and not even spin the tires. I think that is a sign of an engine that is still technically fresh. Now with the 3.73's, I can spin the rear tires with just sudden half throttle acceleration. I have peeled-off by accident a few times from stop signs (oops). lol

I've actually changed the oil first thing after I have changed the intake manifold and valve cover gaskets, so I don't think the sample would be accurate.

4 thousand or 104 thousand ....hhhmmmm

I forgot to mention that when I was looking for another foxbody mustang, I test drove a vert with around 112,000 miles and it rattled a lot more than the vert I have now. I actually installed subframe connectors on my 91' vert, which it did not have when I bought it. The car felt very smooth and quiet even before the subframe connectors were installed.

Most likely 104,000. But, that looks like a 4000 mile interior.
