well i have had my car for a while now... [since the end of April] and i finally changed my oil yesterday [with help from people in this forum i decided to go with Castrol GTX 5w-30] and lets just say my gas milage improved drastically.

1/4 of the gas tank before the oil change got me roughly 30 miles city/50 miles highway

now after the oil change a 1/4 of the gas tank got me 45 miles city/ 80 miles highway


wow

Yeah it's a huge difference of what some fresh oil can do.

I get usually 40-50 city in the first 1/4 of a tank



But I guage my MPG by Trip and Gallon filled at gas station. But I use the same markings on dial to know where I should be.

Useless post.

This is not how you measure MPG.

i dont consider it useless if i noticed that i dont have to go to the gas station every other day

oil changes do help slightly in MPG.

Jumping from 5w20 (Just an assumption) to 5w30 will definitely not help MPG though.

^but you will not see a calculatable difference towards the worse either!

When I first got the car, I was getting 12/13 mpg. I calculated on todays fill up and I got 19 mpg (260mi/13.8 gal). This was wet highway, high speed highway and some local driving. Now if I could keep to around 70 all highway, I would defiantly break 20 mpg.
I'm using 10w40 oil and premixing (3 oz/tank). I think the premixing helps.
