What kind of gas mileage do you get? Options

[GotToyota]

I'd like to have an idea of what kind of gas mileage you guys get. I'll start:

Year/Model: 1995 GT
Transmission: 5 speed manual
Mods: Stock
Recent tune-ups/maintenance: New spark plugs, Gumout fuel treatment, filter and oil change, Seafoam treatment
Mileage: I just averaged 26 overall on my first tank of gas, this was with aggressive driving, and before the tune-up stuff mentioned above.

synthetic oil (changed religiously every 3K)

Why? Even crapy synths are good to 6,000 miles, and the better ones go to 15,000 miles. Get a good quality filter (stay the hell away from Fram, they're CRAP - NAPA Gold is REALLY nice) and good synthetic (Pennzoil Platinum) and change it every 10,000 miles. Anything more frequent is a total waste, and doesn't protect your engine any better at all.

Go here for good oil data.

That's completely true. Synthetic oils are known to actually last longer, and that is even way too short for NORMAL oil change intervals (Toyota encourages every 7500 miles). You can easily hit 10k miles and be just fine. And good suggestion on the Pennzoil Platinum, I use it in mine and it's a great oil. Also, change your oil filter every other oil change instead of each time, it saves you money and you're not wasting perfectly good oil filters.

BTW, I recently got 27MPG staying at 70MPH or below on the highway. Can't wait to get a K&N replacement filter to see if the mileage goes up.

You should see my oil at 2500miles [Granted I live in Houston where there is traffic at 9PM on a weekday]. I use Mobile1 fully synthetic 15w-50 with a Toyota filter and change it at 2500-3Kmiles everytime. The oil is thin and black and the engine feels so much smoother after the change.
Furthermore I'm a lubrication engineer for large engines and compressors in the oil and natural gas industry. Unless you make mostly long highway trips you're above info is just dead wrong. The worst of which is the bit about reusing your oil filter. You can starve your motor for oil on an older engine with higher milelage like that.

x2 I use mobil one synthetic 10w-30 and toyota filters. when I change my oil after 3K it's usually way way darker than the brand new stuff I put it.

and I use a new filter everytime. it's not like changing the oil is a hard or expensive job, and it's not like you hurt anything by changing it more often.
