Default MPG Report

Just passed 1100 miles on the odometer and reset the trip meter 200 miles ago. I'm averaging in the 19s. That includes daily commute, driving around the neighborhood, a trip to Costco, and two trips to the airport. BOOM!

I thought my mileage would improve but it has not. For ALL local driving, I am getting 16.9 mpg.

The main thing keeping my MPGs up is the highway time. It I did local stop and go driving most of the time I'd be in the 16s as well.

Remember that a drop of gasoline, regardless of its octane rating, has exactly the same amount of energy. If you are towing or running a lot in hot weather the rated octane (89) will prevent pre-detanation and allow your engine to extract the full amount of energy from the gas.

Running in a cooler climate, 87 octane and 89 octane will yield the same MPG since pre-detanation is typically not an issue.

My 2013 1500 Ram Sport has just over 8000K on it now...going back and forth to work, with speeds in 80-100k range the truck has been getting 13.8~14.2 L/100K.

Loaded up and pulling, it has been in the 21~23L/100 range. You can see below what I mean by loaded up. This picture was taken while trying to balance the load. 18' trailer @2000lbs, camper loaded up about 2000lbs, atv 700, and 25 gals of gasoline in dry box.

The 5.7 Hemi handles this pretty easily, but the truck needs a lift and airbags to be really functional.

Yea I have aprox 3700 kms on my sport now if I drive the speed limit Im around 11.5l/100km. On the 36 km trip home if I take the secondary road and keep between 80-90 I can do it at 9.8 So Im pretty happy and I only use supreme or 91 octane

I'm not an expert on octane but doesn't the compression ratio of the engine play into the equation? Some motors are designed to run on higher octane. My wife's VW said to run 89 we would run 87 and it ran fine but definitely ran better on 89 and got better MPG. Do the Hemi's suggest to run 89

Everyone needs to understand that octane is nothing more than the relative measure of a fuel's propensity to combust under compression (rather than when your spark plug fires). A diesel actually fires under compression - hence the term "dieseling", or pre-detonation.

So higher octane is no "better" than lower octane, other than the fact that it will withstand higher compression ratios w/out combusting. Many engines of the day will adjust their "timing" based on the octane of the fuel. If lower octane is uses, the ECU "retards" the timing - firing the cylinder before it fires under compression.

I have several "toys" with high performance engines that require 91+ octane. Without it, pre-detonation occurs (which can cause damage) - if detected by the ECU, it backs off the timing resulting in lower performance of the engine.

What does this mean? If the engine is designed for it, running higher octane results in maximum performance. This may or may not translate into better fuel economy. However, if an engine is not designed for higher octane, you are wasting your money using it (and the oil companies love you for it).

BTW - nearly all gas contains the exact same detergents... so it's not "cleaner" either. I do put it in my small engines (mower, snowblower, etc.) because 91+ usually contains little (if any) ethanol, so it stores better.
