New guy from Southern Indiana
Hi all!

As you can tell from the username, I have an SC300 5-spd. Not exactly the most economical car; but we all do strange things in the name of love! I'm well known to my friends as a slow (I prefer safe and thoughtful) driver, and I'd love to learn how to improve my technique and extend the range of my tank.

I regularly get between 24-25mpg over the course of a tank. With the possibility of a job ~50 miles away, I'll be looking for more ways to improve that. I'd love to hit 30mpg some day soon. It is essentially stock. Being a 3.0L I6 weighing about 3500lbs, she's a little thirsty. At 75mph, it will turn 3k RPM, so I tend to stay in the mid-low 60's on the highway (limit here is 70).

I have another car which is the SC's polar opposite. An '85 Buick Regal T-Type (It's like a Grand National). I recently completed doing an engine swap to a similar turbo V6 as the one that was in it. It's my fun car, and I plan on having a lot more fun with it in the future!

I love to wrench on things and look forward to learning from (and with) you guys! Anyone else in the Indiana/Kentucky/Illinois tri-state area?

Start with the two lists 65 things and 100+ things. they are linked at the top of the page.
See what you can live with.
I have a Q45 and can get 30+ on the freeway on a regular bases. But I 'adjusted the NUT behind the wheel' and run a little tall er tire thanstock(I'm on the freeway alot)

If you dont have a scangauge, I'd get one. The Q has an mpg screen that I was addicted to prior to coming here. THe scan gauge gives me alot more info.

ps. cant say that i realized the 300 was a straight six!

reminds me of my 66 mustang w/ a 200ci straight six.

Welcome! I know you'll find plenty of info here. You didn't mention the year of your SC300. I know you need a few posts on here, before you can do pictures, but it would be nice to see what you have.

I remember a couple of yrs., where to me, that model was quite curvasious! (making up new words?)

Bumping tire PSI will help anything.

I have sort of opposites too: Kawasaki 250 Enduro 112mpg/ Honda Silverwing Interstate 53-64mpg.

Honda CRX 45-62.9 mpg/ 6.2 Diesel Suburban K10 up to near 30mpg. (has manual hubs)

I kind of liked this pic. As far as stock colors, the light brown wouldn't show dirt
too badly here where it rains a lot.
