I rather work on a gasoline engine, there is SO many ways to improve them, a diesel is fairly dialed in.

NEW NEWS:

So here is some proof of how fuel vaporization matters…

A 33% improvement just running the winter bland gasoline which has a more ability to vaporized easier.

“In winter, gasoline blends have a higher Reid vapor pressure, meaning they evaporate more easily and allow gasoline to ignite more easily to start your car in cold temperatures.” https://www.gasbuddy.com/go/summer-b...blend-gasoline

The change from 15MPG to 20MPG is 5 MPG improvement, that is .33% improvement, that is a major change.

I discovered this when I took the Explorer up to road speed, which is 75MPH posted and of course I was running along with traffic at 80MPH.

And on a scan of all my gauges I saw what seemed impossible, she was doing 22MPG: 22MPG at 80MPH…this did not stay 22 as load as other things acted on the SUV but it stayed at 19 to 21 all the way back to home…even when I kicked in the A/C. This was a drive of about 9 miles.

I took her out again the next day and it was still reading 18/20MPG at 70/80MPH….this does not compute.

All summer long she was reading 50MPH = 28/32MPG, 65MPH = 18MPG, 80MPH = 15/16MPG.

So this morning at 3PM I woke and wanted to test her a fully as I can….so first thing I checked was my scan gauge II was still set for a 4.6 engine… I thought it might had reset its self to different engine size. It had not, it still reads a 4.6.

So up on the freeway and ran normally until all was warmed up, then began testing on the return leg of the trip…

50MPH = 29/30MPG, 60MPH = 22/23MPG, 70MPH = 21/23MPG 75MPH = 21/23MPG even 80MPH was showing 20+MPG WTF!!!???

The really odd thing is my 50MPH reading of 29/32MPG is the normal reading I have been getting, it is the readouts for above 60 that are off….the 10MPG drop at around 60MPH seems to have disappeared somehow.

Either improve, or keep them running with some makeshift fix. No wonder I see some cars from Argentina which got the EFI replaced with a carburettor once some electronics started to fail.
