I was experiencing some issues with our 2014 Ford Focus. Nothing crazy, but a bit confusing at first.
Many cars have fuel economy displays, taking data from various sensors and turning them into something potentially useful. In my case, I noticed two of my readings that appeared incorrect. (The level has always been- on most cars). The first was "Distance to Empty". After a tank fill, it reads around 575 km. It was showing only 410km on a full tank. After a few more days, it seems as if the fuel economy was getting bad.
It took some thinking and web searching. The problem was obvious, but I was looking at a bad reading and bad fuel consumption. Turns out to be related to high sulfur in the fuel.
First, calibrations aside on fuel guage...the contact points for this car are exposed to the fuel. There are 16 sets, I think, meaning 32 contacts for the float wiper. Sulfur compounds will coat them over time. It did.
Secondly, the injectors were also working harder to deliver fuel for the same reason...sulfur coating.
As a former Chevron employee...I looked into Techron availability here in Thailand. (There are CalTex stations) Turns out that Chevron makes a concentrated form of Techron additive, called Techron PLUS. They recommended 2 bottles, one each for two tank fills. I did one bottle, then after half tank used, topped off for a trip to our property. This Techron formula specifically takes care of the sulfur AND coats the contacts to prevent new formation.
Good economy for us is 7.0 liters per 100km, (33.5mpg) but we were using 10.2/100km, or 23 mpg! Big loss.
The trip was amazing. A one way drive is 250km, 500 round trip...never made it both ways on one tank. This last fill shows 185km to empty still, and I am home! Average consumption down to 6.7 liters per 100 km. (35 mpg). Power awesome and fuel to burn on only one treatment.
The downside? one bottle was 480 Thai bhat...$14.50. Worth every penny!
Just in case you don't know...Techron laced fuels have low amounts, designed for every day use...all American auto manufacturers use it for DOT testing.
