Don't know if you know the story, Grishams first book was probably his best, A Time to Kill, but it was too good - a literary masterpiece, won awards but didn't sell very well. Grisham went back to the drawing board and checked out best sellers to see what the formula was to write a best seller. He wrote The Firm and he was a huge success.

Do most turbos require premium gas? If it helps the the engine last longer, could be worth the added expense. Performance wise it shouldn't matter?
I've been using BP with Invigorate 87 octane gasoline, which BP says exceeds tier 1 requirements.
Car runs great. But, I want my baby to have the best! So midgrade or premium?
I used midgrade in my 1.4T Jetta

I have to use 91+ in it now because of the mild tune but the rest of my fleet do fine on 87. I try to use top tier but I admit I usually shop price.

many more companies from this area on the list that didn't used to be there.
One still missing is Speedway, a subsidiary of Marathon Oil. Marathon's products are
meeting top tier, but the Speedway fuel doesn't.
I noticed that Valero is now on the list. Their differential between PUG and RUG
is 40 cents, while Shell is 80 cents and even more at some stations.
So if you're looking for PUG that meets octane and has additive packages
that are above minimum...

One could actually put lower grade gas into engine with much less fear of long-term damage than 20-30 years before. They won't get any fuel economy (or hurt it) due to ECU adjusting timing and thus dropping mileage, but a real damage due to uncontrolled explosive combustion (knocking) is much less likely.

"They are out of 87, I can't put 89 in!"
No benefit to 89 octane for your engine.

Higher octane is required whenever engine's timing tolerances are such that combustion needs a good control. This includes high compression ratio naturally aspirated engines and high boost supercharged and turbocharged engines. Basically once the engines have all this fancy hardware that squeezes more torque, horsepower and efficiency from less displacement, the price you pay is that fuel needs to be very specific, or all that is defeated. For example my previous 2012 BMW 328i required minimum 89 octane, current 430 needs 91.
BTW, there are so called low-boost turbos that don't require premium gas. Volvo used to sell cars with those (nowadays they all are premium recommended).

Shipping weight is 40 lbs so it’s not going to be cheap to ship it to where ever they decided their customer service dept is.
VERY NICE Yammy RXV1. That was one of the “top of the heap” AVRs. Looked at those pretty closely a little while back.
U571 will give your entire system a work out, particularly your sub(s).
If it was one of the amp modules, I could pull one board out and replace it with another (there’s 9 of them). If it was once of the speaker connectors, I could pull one and solder in a new one. If it’s a CAP, it’s DOA. I give it another 24 hours to see if I can find a service facility.
I’m already starting to look at new units (maybe refurb). I like the Yamaha 3080, the Denon X8500, Anthem MRX 1120 (which Anthem has on sale for 20% off right now) or a Marantz SR8012. Given the Pioneer-Onkyo marriage snafus, I’ll steer clear of them.
But, my surgery on the old unit is not over....yet!

One of them had been suffering from some medical issues, and had been away from the sport for a while. He had an opportunity to get back in the car this past weekend, and ..... well, I'll let the video tell the tale:

Reiner played an eternal optimistic health nut providing death therapy for the suicidal Reynolds. For me the funniest scene in the whole movie is the untimely demise of Dr. Maneet shown in this trailer at 2:05.

All the rest are pretty much "top of the line" for each brand. I like that Yamaha unit. But, both the Marantz and Denon have the Audyssey room/speaker correction, which is one of the best in the biz.
Still, have the Pioneer "uncovered" and am swapping out parts. Good thing Parts Express is only a 45 minute drive away. My soldering skills are rusty, though.
Got a 7.2 system set up (2 subs). Not really thinking of upgrading to Dolby Atmos, at least not near term.
Will let you know.
They were very vocal about their feelings that premium gas should be used in all Volkswagens! They said they would run cooler have more power and just run better. He was right! I would use the good stuff but once in awhile I would run a tank of regular and I could tell the difference in spite of suggestions from other VW owners that it was a placebo effect.
My Volvo was premium-recommended, and by the time the price difference was more than a MPG difference made up for, I was solidly over 100K so I figured I would be nice to it. And I use premium in the RDX anyway, because my Costco membership sometimes gets the price difference to almost nothing ($2.55 today vs 2.39 for regular at other gas stations).

Not that I would advise driving either one at anywhere near their top speeds.

Having said all that the wife put 87 in it by mistake early on and nothing seemed off. MPG is terrible either way.

I feel like on the RDX that you have so much extra power already with that type-R turbo that giving up 10% is not going to be noticed. But with the TLX 2.4 weighing 3500 pounds I want that extra 10% of power in some passing situations.
It does seem like the Acura owners who get 250k+ out of their cars seem to be putting premium gas in their vehicles. Is there a chance that the higher octane and the detergents in premium help the engine last longer? I really don't know. Probably not. But there's a small to medium chance maybe that it makes some difference in the long run? Difficult to say. And we'll probably never really know. But since I'm considering buying out my TLX and keeping it long term I think I'm going to stick with premium.
With the driving we do, I could lose 100HP and probably not notice. And remember, all that gain/loss is at the top end of the rev band. If you are bopping around town never breaking 3,500 RPM you aren’t getting into that theoretical tuner band extra anyway.

No offense to your friend, but he needs to rethink that detail, and how close he wants to get to a large tight group of amateurs like that.

2018 RDX, 3.5l: 252 lb-ft torque @ 4900 rpm, 290 hp @ 6200 rpm
2017 Honda Accord 3.5l: 252 lb-ft @ 4900 rpm, 278 hp @ 6200 rpm
So same peak torque (at same rpm), but 22 hp peak power difference at same rpm. This means there is tuning difference (perhaps just software, perhaps some hardware), which justifies premium gas. Basically it squeezes a bit of extra juice at high revs. It also means if you run RDX on regular, you'll see lower peak power, but otherwise it may be imperceptible to you and I'm not even convinced that the gas mileage would suffer.

I’ve mostly put mid grade in the TLX as a compromise, but seems the same on regular.
Ditto on the new RDX but not enough miles on that yet to really tell.
Around here, lucky if you can find the delta below $.50. I miss the old days when each grade level added a dime!

He loves the fact he can drive through the city and there is no engine noise. OK. I would feel weird without engine noise, but I am slow to want to change...I like my gassers.

That's why I have said more than once that I'd like to see if there's a real fuel-based difference if you were to tear down high-mileage J35 engines.
