Is premium fuel really needed?

Fuel type?
I've been filling my NX with premium unleaded ever since delivery. Gas prices are starting to creep up a bit now that summer is approaching and was wondering if it would be okay to go for mid-range or regular gas instead? I know premium gas is recommended for the NX but just wondering if anyone else is using regular as and if there is any differences in performance or any potential issues

I didn't realize you guys with the turbos had to feed it premium. Just one more thing to like about the hybrid. Of course, we don't get to go as fast though

Normally I have not been too concerned about the difference in price. However, I recently ran across a station charging $2.10 for Reg and $2.80 for 93. 70c per gallon difference is outrageous IMHO and I'm concerned with depressed gas prices it will become the norm. I was stuck paying for it that time since I needed it for my race bike.

I have been using both, regular and premium. I have not found any difference in performance, MPG or power. Certainly cannot hurt the engine. If yo can find fuel without Ethanol, you should get 1-2 more MPG, minimal increase in power over E10

We only use premium because the car is labeled "premium required". However, when we asked the sales person about this, he said the dealership only stocks regular unleaded and they put it in all the cars they sell.

OHh! I won't use regular here, (85 Octane b/c of altitude) but also it can cause early detonation in the cylinder chamber & "pinging". Not good in long run for pistons, crankshaft, etc. Just my 2 cents worth!

Well sure, there is that. it isn't actually that much, but regardless, the price difference in fuel and the better mileage combined will never make up the additional cost of the hybrid. Oh well, still like the hybrid. That's why they make a model for every taste.

Actually lower octane often give higher MPG. The higher the octane rating, the more difficult the fuel is to ignite. The best power and MPG comes from using the lowest octane possible while avoiding detonation.

In the end when buying the NX I clearly new that premium gas was a requirement. I guess I don't understand this whole thread. I'm sure all of you new this before buying your new NX and if you didn't, shame on you.
You need to use nothing less than 91 octane. Using less than that can potentionaly harm the engine. The operative word is potentionaly. If your willing to use regular, you are taking a chance.
Good luck!
