Anyone use Premium Fuel?

I got a marginal performance and mpg increase from ethanol free 91

2.0l ecoboost
91 octanes only

The entire point of this thread is whether octane makes a difference ON THE HYBRID!

It absolutely makes a difference on the ecoboost, and every other engine that adjusts timing and/or/ turbo boost based upon available octane. Anyone who questions or doubts this has nothing to contribute to the discussion.

Octane is not energy; it is the ability to resist premature detonation during high compression. The more octane, the higher the compression possible, and thus increased power and/or mileage.

That is *all* octane does.

Entirely.

When timing/boost are not being adjusted, octane has excactly two levels: enough to prevent knocking,, and not enough. (there is a tiny transition zone where incipient knock can be detected with sensors).

But all of this has nothing to do with the hybrid, and this is the hybrid subform!!




there won't be. Unless you're somehow driving it in a way that is causing knock. Back to the enough not enough dichotomy

Why does it seem that Hybrid owners ‘hate’ EcoBoost owners??? It’s certainly not the other way around!!!

The OP said nothing about hybrids. He was reading the manual sections that apply to both EB & Atkinson.

Top Tier fuel makers vary the additive % in Premium vs Regular - with Premium getting more of the additive.

A cleaner ICE, whether EB or Atkinson, will perform better. How much better? Is it worth added cost?

Now if the OP was specifically asking about Hybrids - there would still be plenty of EB folks responding because EB folks lack reading comprehension skills.

I use premium gas and still pay less than what I paid on regular gas in my previous ride.

Pemex only!

Pemex only!

“Top Tier” gas has a higher detergent formula than non top tier. Since Pemex is not top tier - do you use aftermarket (Techron) or OEM (Motorcraft) detergent/additives occasionally? I think the recommendations say a $25 bottle every six months or so.

Keeps your baby squeaky clean

This is what I use, is it good?!

I certainly don't.

I'm just pointing out that info on how an ecoboost responds to octane (it likes it!) has nothing to do with an octane question in the hybrid section.

A hybrid owner posting in the ecoboost secant about how premium made no difference for his would be equally pointless.

The OP said nothing about hybrids.

But this is the hybrid subform. And the response to premium is one of the things that radically different between the two engines.

Top Tier fuel makers vary the additive % in Premium vs Regular - with Premium getting more of the additive.

it is entirely believable that some manufacturers would put enough extra additives in premium to have measurable effects.

Good question.


more seriously, it depends upon what is in it, and it would take some research.

We know what is in Techron: it's what Chevron uses to create it's top tier fuel in the first place!

There is a lot of snake oil out there, some of which have folks that swear by it. Some harmless, some harmful.

If you can determine that it comes from an oil company that makes TopTier fuel, it's likely good. And if it's not, than what do those folks really know? The top tier standard was developed by the companies who make high compression engines; none of them sell it. Rather, it specifies what they want to count on being there.


a side note:

* the difference between pure gasoline and 10% gasoline is about 3% fuel economy regardless of engine type (less energy by volume in ethanol). If all else is equal in the gasoline used, octane will be higher with the ethanol, and more power could be generated in an engine playing with boost/timing.

Check the ingredients for Polyether amine (often abbreviated as PEA)

It is the highly effective & commonly used detergent in Top Tier Gasoline and also aftermarket additives. Was a neat discovery by some smart “nerd” scientist

Probably because OP has/had hybrid as shown in sig/status info, and opened the thread in the Hybrid drivetrain forum section.

Which obviously not all threads are opened in correct areas.

There are never any Hybrid owners responding in the EB subsections.

Their discipline is something the EB owners can only aspire to.

Well since I haven't seen anyone who lives in a high altitude area comment...

I run Mid-Grade in my hybrid but here in NM that means 88 octane because our "regular" is 86 octane.

I will say I struggle to understand why the 86 octane won't work because the whole reason for lower octane content at high altitudes is that altitude has an impact on the density of the air the engine is ingesting and 86 is supposed to work like 87 because of that.

Probably because the boost provided by the turbo lessens the affect of high altitude. The reduced atmospheric pressure at high altitude does indeed have a significant effect on a , but less to on a boosted engine naturally aspirated engine
