MPG updates

[Sal-XK]

Been driving a lot with lots of idle time still getting 15.6 right now mixed city/hwy

What kills me is I drive MAYBE 5-10 miles a day all city no highway, plus I dont have the updated tire size in the computer so it a little off as Matt said it would be

I ran a year before I got the sc programmer and it was about a 2MPG gain after the correction. That was running the 265's

WOW! Im not that optimistic but gaining 2 mpg would be nice, thatd be 13mpg city!!! pretty sad when we HOPE for 12.5-13 hahaha

The minimum octane down here is 91, so i dont think it should be an issue in a Hemi.

Greg (mate of mine who has an 07 Hemi, same saguaro front bar and rear bar) got on his last melb-bris-melb trip (round 4000km trip) he averaged 16l/100km (14.7mpg) on std 91 octane, no tune. Mixed use, some offroad, some beach, some city, some highway.

Wont be an issue for him, he has just bought a CRD and all the gear is being transferred.

I wont mention that i got 10.1 l/100km (24mpg) average over the last 2 trips, including offroad use. Ooops, just did. Just doesnt sound as good as a Hemi does under load up a nice long hill.........

Oh the pleasures of a diesel!! Yea it may not sound like a HEMI but that fuel economy is awesome, only if an inline 6 Cummins could have came under the hood, hhhhmmmmm!!!! To update my mpg's the last trip to Rausch Creek I avg'd 15.3-15.5 on the way down (hwy) and 15.4 on the way home, by far the best I ever have had. I was using Sunoco 89 and will continue to as it seems to run the best with their gas. It will be interesting to see what my city mpgs stay at...

I've read that the way octane is calculated is rather region specific. There is no international agreed standard for doing the math.

In Europe there is 95 and 98 octane unleaded. The 95 octane actually corresponds to 87 octane in the USA.

So does that mean if he is running 91 octane he is actually using an octane less then 87?

Ahhh, i didnt know that.

We have 91 as standard, 95 Premium, 98 Optimax, and then some now have 100octane. Dont know what they match up to but the 98 optimax with Toluene was a match for Avgas back when i had the drag car.
