"DO NOT USE 93 OCTANE" ?

[Cheshire]

I wish I knew how you average 17 mpg. I'm almost at 3k miles and have tried 87, 91, and 93. I've been averaging at best 13-15 mpg and thats sometimes with a light foot! I even did a road trip from Houston to San Antonio doing 80 mph on the highway getting 13.1 mpg.

I'm getting my first oil change at 3k....I know a little dated I usually wait till 7-10k but just doing it this once. Hopefully it helps my mpg.

Usually I'm a very aggressive driver, but with the Bronco I've been trying to drive slow and conservative to see how good the mileage can be. I'm sure if I start gunning it and driving aggressively on the highway, the mileage will drop to what you've been averaging.

Lol honestly that is with a light foot about 80-90% of the time. It’s been a little concerning considering I was expecting at least 17ish. This is by far the worst mpg vehicle I have owned.

Where was/is it?

right by the access ramp to 280. I believe on Broadway? if I recall correctly.

I worked as a summer intern at an ARCO refinery near Long Beach, CA In the early 70’s. I was working in the QC lab picking up samples and sampling tanks before the product was sold or shipped. There were dIfferent tanks for each grade of fuel they produced. One quickly learned that the sampling equipment was specific to each grade of gasoline, diesel or jet fuel. Though the sampling apparatus did not appear to have any mechanism for potential tank contamination, using the ”regular gasoline” sampling equipment on a tank of ARCO Clear would get you fired. I do remember taking samples to the “engine lab” where the Motor Method octane rating was determined. There was a one cylinder variable compression gasoline engine there that ran at low RPM and knocked a lot! Unfortunately I was too young to ask a lot of questions back then.

Due to the care of cross contamination they instilled on me, I do not like the “one hose” gas pumps either. If your buying premium, you get a full hose of regular.

Was the "clear" the jet fuel? They have strict quality standards for that stuff. The consequences (and liability) of sending a slug if water or sediment into an airplanes tank are huge.

You guys crack me up. Gasoline stays fresh for months. Gasoline pumps have built in fuel filters.

Lol.

I agree, logic has nothing to do with this. I still don't do it. It took me years to put the actual gas grade that the owner's manual recommended instead of the higher grade because "it is better for the car"... I also know that ALL gasoline sold in the US has to have a minimum of additives and quality yet I try to look for "top tier" gas.

No. At the time the ARCO Clear was their premium gasoline. Sorry but I don’t remember the octane rating. Their jet fuel, JP4 and Jet A, was kerosine/diesel “grade”. IIRC, flash point and “gel” point were important. I remember sampling a huge tank of JP4 one night with a US Navy inspector observing…. They were very particular about what they bought.

I’m getting 17.4mpg average on 87; and I’m going 75-80 on the highway. Mashing it around town.

Maybe the 1.25” wheel spacers allow the tire to block the parachute aspect of the rear of the fenders. A stretch, maybe, but maybe not.

haha my ford dealership experience was a total shitshow too.

No matter how much I like this bronco, it’ll be the first and last Ford I ever buy

Im right there with you!!

It is more like a requirement. You can offer ethanol free fuel but are required to divert a certain amount of corn-fed black angus ground beef into the tanks of our vehicles. That corn could feed more cows or the land could raise alternate foodstuffs for direct human consumption. It is simply put a way for the federal government to subsidize corn farmers without direct subsidy payments.

Ethanol laced fuel returns less mpg. Minimally less, unless you run E85 but pure ethanol has 34% less Btu power available from it than pure gasoline. And the amount it actually reduces our dependence on foreign crude is suspect when it takes large fuel and fertilizer inputs to produce the alcohol stock. It is more about "see what we you duly elected congressman are doing for our country and the world"

Or more likely lobbying from the plastics and rubber fuel system components industry grousing that sales were down

Well said.

 

[Jawaburger]

I have an option of ethanol free 91 here, or regular 91. WHich one is the best for this?

If I had the choice I would certainly go with ethanol free gas.

Water by itself is a poor combusting fuel.

That's not what my dealer said.

I owned two new LR Defender 90s when they came out. If you floored them on the highway going downhill they'd max out at 80 mph. I got 10-12 mpg in those pigs. My 4Dr 2.7L BaseSquatch is bigger, much faster and more powerful, so not bad relative. I also owned 4 Wranglers and always felt they were underpowered. The Bronco does not feel underpowered to me.

I know that area well, thanks. I have family in Burlingame.

 

[cclkramer]

2800 Miles and have used 93 the entire time. (aside from the original dealer fill-up, which I'm sure was 87) No issues.

I asked my dealer to fill my truck up with premium before I picked it up. They said NO! They were to cheap. Said they fill all the vehicles with 87. I use premium. My 7.3 f-350 deisel dually gets better mileage.
