Idunno maybe its jsut me but lately Ive noticed that my 90 DX Rolla is eating up GAs alot quicker? Hopefully its just my crzy idea but if not what are some things I can do/change to maybe aliviate this problem?

how can u tell??....are u keeping track of how many miles between fillups??....has ur driving style changed lately?......had ur foot grown lead??....

try this....for each fillup....reset ur trip odemeter and keep track of a few fillups to determine gas consumption......

maybe you need a tune up. check your air filter, tire inflation etc.

my foot recently turned lead, but i really dont see much of a diff. Correct me if im wrong but isnt the peak gas milage around 50 MPH for most cars. Yeah im really revving it like i go up to around 30 in first.....could that be bad for my car? the owners manual said max is 33 for first

The peak gas mialage in every car is different, as a general rule:
fuel used = (power output - power loss) / (speed - friction encountered).

Usually tho, you will find this to be around 50mph (~80km/h), or in 4 cylinder cars, around 3000rpm.

As for revving hard in first, that is only bad during break-in, every other time it will just waste fuel. If you maintain your car well, it will happily run at redline all the time and not do damage.
