I've considered trying mid-grade or premium, but the cost always turns me off. I'm thinking about trying it on a road trip, but I get the impression that it takes a few tanks for the ECU to make adjustments.

Shell is one of the places I look for when I'm travelling. I usually stick to BP, shell, Pilot, and Loves

I saw one of these along 65 last winter. I think I'll stop on my way through this coming year to see what the fuss is about.

 

I’m pretty sure the ecu adjusts on the fly, no?

 

I know this was tongue-in-cheeck but Shell is my choice, particularly my neighborhood station which sells ethanol-free 87.

 

I think so, but I thought I had read that it takes a few tanks to really adapt to a different octane. Maybe I'm wrong. I thought I had read it in one of the other 200 octane threads around here.

I know the computer can make some adjustments in real time, but I always thought it took awhile to actually learn things. I experienced this when my '03 wouldn't run after changing the timing belt. The belt wasn't the problem, but having disconnected the battery reset the ECU and it wouldn't run due to carbon build-up in the throttle body. I pulled the intake tube and cleaned out the throttle body and it fired right up. If it could really adjust on the fly, it shouldn't have been an issue, IMO.

This wasn't my theory, either. I found out by googling the issue.

I'm sure someone will be happy to tell me if I'm wrong, though.

 

87 non ethanol 99 percent of the time

 

I try to hit QT when I’m not traveling. There are Bucees all over Texas and other than the lines I like them.

 

Here in Utah I Gas up at Maverik, The prices are in line for the area and most not all but most have the ethanol free gas that I get for both my Auto's and boat and the use of the Gas card save 10 cents per gallon and get you points you can use for coffee or drinks and even save em up and use them to try to win shit like a guy at work got a heck of a nice Side x Side 2 years ago.

 

93.....never less.

 

Being supercharged kinda dictates that.

 

It does

 

87 from Top Tier brands like Arco, Shell, Chevron and Costco. I stay away from shady gas stations

 

Also, Premium gas does not mean it is cleaner or of higher quality. You are wasting your money on premium gas, this truck doesn't need it. Buy 87 but buy it from Top Tier gas stations, their gas has additives and detergents.

It is just in your head.

 

Any notable difference in performance, mileage and gas consumption?
Just curious.

Used to get Costco premium gas. The friendly gas attendant came over to tell me stop wasting my money.
Said any top tier regular gas would do.

 

Anyone else in Colorado notice 85 is regular gas out here? Allegedly it’s ok at higher altitudes?

 

Not me personally, but I've seen comments from members who seem to use it without issue.

What's the typical mid grade and premium octane there? An how bad is the price gap?

 

I think we're 85 reg, 87 mid, 91 premium, or something like that. I've always ran 85 in everything other than vehicles that require premium (Lexus) and haven't had any noticeable issues.

Not a major price gap between them most of the time.

 

I don't experience any knocking. I must however run 93 as my engine is supercharged.

 

87 around town and 93 when doing long hwy trips

 

Filled up this morning with ethanol-free 91 octane gas in Parker, Arizona at Monarch gas station. She purrs like Stormy Daniels.

 

Be aware of placebo affect and marketing. Your engine's ECU doesn't "learn." Your engine's ECU doesn't have an octane sensor. It can detect knock which is horrendously bad. Your ECU will attempt to protect the engine by reducing the timing through knock retard. This is a defensive mechanism and not a learning mechanism. Your ECU will not invert this strategy and try to advance timing if it detects no knock. Cars with high compression ratios, forced air, and tuned cars need the higher octane to control the detonation due to the increased heat.
