Regular or premium

We’ve all got plastic tanks

Touche’

fuel lines, pumps, injectors, etc. ???

We’ve all got plastic tanks. But agree otherwise.

With a rubber liner.

In the end it still comes back to full circle, it’s up to the user and the engine runs on both... put in what you feel is right.

"Rust" or oxidation requires the presence of oxygen or an oxidizer.

Rust in fuel tanks comes mostly from the filler neck or the gas station. And most of the particulate in the tank isn't "rust', but is sediment, like sand, dirt, etc.

Agreed, we run 93 in our explorer platinum. Period. It has never seen 87 unless the dealer put it in it when we bought it. I also only use amsoil full synthetics.

Now I've learned something else.
Learn a lot on this Forum

Off topic, but this is familiar to me from my snowmobile with variable exhaust. I take it apart and clean it every 2000 miles. Used to use "regular" 2 cycle oil but then switched to expensive synthetic. The difference of buildup on the internal parts is HUGE. I'm a convert to paying more for top quality consumables that keep things cleaner now. Worth the $$$$

We take it a step further and run non ethanol 91+ octain in all our small engines, PWC, ATV and dirt bikes. All two strokes get synthetic oil.

Good point but...The eco boost was supposed to save people money. V8 power with 6cyl mileage. It makes the power. Does it save any money, if you a filling it with premium?

It sure does. It has more power and more fun to drive than my other V8 Expeditions that average 12mpg compared to my '16 getting 17mpg.

I can’t get my 5.4 down to 12 if I try, even if I lead foot it all day it stays around 15... I get 17-18 highway here.

Must be our crap fuel LOL. Since the cold snap here the '04 5.4 is getting consistent 10mpg. But it also gets warmed up longer before being driven too so that's why it's down from 12. The '16 gets warmed up until the engine oil temp reads "normal" on the display.

I let mine warm up 5 minutes usually and go

I wonder if the on board computers are lying to us LOL. I check the '16 on the dash too and the '04 & '06 calculated by miles and fuel used. All tho the '04 is the 2 valve and the '06 was the 3 valve. The '06 got better mpg at about 13-14. Long highway trips up to 15mpg.

I’ve calculated mine once for sh*ts and giggles and the computer was actually close. I think they can be innacurate at times yes.

I stopped measuring MPG years ago on my 03 Expy
just glad the dang thing fires up & moves
the Falken AT3W tires have already earned their cost in this snowy winter
my old truck might be my best friend .... I love driving it !!!

 

[ExpeditionAndy]

I use 87 for around town and when I go on a long trip I switch to premium. I really don't see a big difference or any difference in performance. I do notice a difference when I drive out of PA using a full tank of PA regular gas, my mileage drops by at least 2 mpg. If I switch to premium, I notice it only drops by 1 mpg. I think they have more ethanol in their gas than we have in Indiana.

 

[deweysmith]

The injectors can and do meter fuel by the gram. The computer is far more accurate than the ol’ pump-shut-off method, for sure.

I wont argue anymore about this. You don't even own an Ecoboost. If you ever own one run some 87 in it then run some 93 and get back to me. 3 people in this thread have said their trucks run better on 93 over 87 and youre basically calling us liars.

"Run better?" What's that mean, what's the criteria for "better"? Different?

I've run 93 and 87 octane in my '17 and without access to a dyno I can't tell the difference making 93 a complete waste of money. I don't doubt there's more power and better fuel economy there, we've all seen reliable tests, but it just ain't use-able in normal driving and my experience towing a 6000 pound trailer shows no need for it either. I ran the fuel tank down to the 20-minute fuel light blinking before filling with 93 before towing. Towed fine. 87 tows fine too. Maybe the guys towing 9000 pounds need it?

Fuel companies calling high octane fuel "Premium" is advertising BS pure and simple. Nothing premium about it, just something to make owners of expensive cars that don't need high octane feel good and make them think they're being kinder to them. Modern cars with electronic engine controls and devices like knock sensors can handle their minimum octane fuel just fine.

Fuel companies make all sorts of claims and want to sell you "Premium" gasoline for sure. I doubt it's less profitable for them.

Haven't found it here in Virginia but there was a gas station near me in Ohio that sold 120 (100? 150?) octane "racing fuel." No experience with it at all though. I know the guys running racing snow machines in Wisconsin used to get AVGAS in cans at the airport FBO.

I admit, gas mileage makes no difference to me mainly because I do not pay for gasoline...BUT in as much as "octane rating" is really nothing more than a measure of detonation preventative, it would make sense all other things equal, to use the higher octane.

FWIW.....I use a min of 93 in all my vintage bikes since when they were new, you and I were buying 100 & 105 octane at the pump!!

Like I said I'm not going to argue anymore. There are numerous other threads about using premium on here and they all end up the same way. Guys saying premium is better for the application and guys saying premium is a waste of money blah blah blah. Fill up with whatever you prefer

Please don't post bad information. Premium, according to owners manual, is recommended for towing. I own a 2011 Mustang GT. It requires 91 or higher all the time. The manual states, it will run on 87, but with reduced performance. My Lincoln 4.6l DOHC, also says the same thing and adds a "premium" sticker by the gas cap. The Ecoboost just re-worded it the manual. It basically says, its recommended for severe service. In reality, you are driving around with reduced performance. Nascar and drag racers use high octane. You sir, own a expensive vehicle. It also is stupid, to run down, fuel until idiot light blinks.

 

[chuck s]

Recommended is a much different standard than required.

Just how much "reduced performance" is the question Numbers aside it's inconsequential in normal driving of our trucks. Performance cars (or pseudo performance cars) will feel the difference. That 350 Mustang will still get to the next stop light sooner. Heck my S2000 will.

This is what Colonel Cooper referred to PII. Preoccupation with inconsequential increments.

23 gallons is my normal fill up. At 60¢/gallon extra for "premium" that computes to nearly two six-packs of a good micro-brew to put it in a meaningful number. I'll drink the beer until I need some increased power.
