Lucas fuel treatment anyone

[GatorBait]

Anyone ever try this Lucas fuel treatment? Says you can use instead of paying for premium fuel. Just used for first time along with premium fuel. Will see if it makes any difference with fuel consumption.

I think @FordTechOne will chime in quickly on this one.

I’m not aware of any data showing how effective the Lucas fuel conditioner is, but it does not increase octane, so if you use anything less than 93 you will see a decrease in performance and fuel efficiency.

Any reference to fuel octane would be in the context of carbon buildup causing knock, resulting in the need to use higher octane. Modern engines run much cleaner and the PCM controls timing to eliminate that scenario, so that is an outdated claimed benefit.

If you run top tier fuel there should be no need to run additives such as this.

They make a great product for diesel engines that cleans/lubes injectors, AND also cleans the DPF. However, on a gas engine, I think that Chevron makes the best for cleaning/lubing the injectors. It has Tecron in it that really seems to be the market favorite. With the standards of gasoline delivery and tank status at the stations, this Chevron stuff is cheap insurance to protect your injectors.

Why are there certain tunes that are called "91 octane?" Am I to believe that said tunes allow the Raptor to run on 91 octane?

I believe those aftermarket tunes are optimized for 91 octane use, such as in states like CA where you can’t find 93.

For reference, Ford tuning will allow you to run on 87 octane without hurting the engine. Their tuning is adaptive to octane as most manufacturers are these days.

Very interesting.

Now, if they "retune" it to run 87, will that gas mileage reflect as worse or equal to stock gas mileage?

87 gas mileage with tune and without the tune?

Is 87 octane fuel as energy dense as 93? No, so fuel mileage would decrease.

Pretty much everywhere in the west. 91 is the best you can find.
