In Poynt, if you click on the gas station of interest, and then "See Station Details", it lists the prices for every grade.

I don't know if it got updated since, but just D/L'ed Poynt after seeing this thread, and you can search cheapest prices by grade, don't even need to go into station details...

Poynt is sweet btw! Integrates well with Google Maps app too.

Poynt is supposed to be adding a gas price feature as well.

It's in the latest version (1.5.4.12)

I've been using gasbuddytogo.com for some time now, works great. I hardly ever visit the stations listed, so long as I know the ones nearest me are within a few pennies of the stated lowest prices. I know people who will spend $2.00 worth of gas to save .02 by driving across town, though! lol

I enjoy lifeinpocket for all my search needs.

Poynt since it has many other features.

Too bad Poynt doesn't work in Canada... yet... maybe one day

For now I guess I'll just use gasbuddy.com on my browser - actually has quite a bit up to date in the Fraser Valley / Lower Mainland , BC

GasBuddy.com is working on a BB version.
They already have an app for iPhone and Android.
Good Luck
