I see these Premium vs Regular threads in every forum any more. They are usually started by people who for the first time in their lives, purchased a vehicle requiring premium.

Well, every vehicle I have owned in the last 17 years has required premium...and not one of them was a turbo. Honestly, I never made a big deal out of it. I was just glad I had gotten to the point where I could afford such a vehicle. It seems odd to me for people to be quibbling about gas prices when they can spend $40k! I would think that the practical thing to do if you did not want to pay premium gas prices would be to look at vehicles that do not require it. There still are plenty of them out there.

 

This thread was intended for actual owners of the new NX 200t and their experience. The last poster has never even owned a Lexus I don't need a lecture on what car I should buy. This thread is out of control with useless comments and opinions. I sure was glad to learn how bad the Genisus was.

Corrado was the only one to take the time to answer my original question. Thank you.

I think this thread should be locked before it gets more out of control. There is nothing to more gain here.

 

Lol. Becuase if you don't own an NX, You obviously don't know how octane impacts fuel tables and engine timing, right?

You don't need to own the car in order to be a member of its forum, just a general interest. I also belong to the Nissan GT-R, Corvette C7, Ford SVT raptor, and Ford GT500forums. I don't own any of those at this time, does that mean I don't deserve to post there? Lol

I worry you don't know how a forum works. It's called a location for conversation as people wish to discuss. Not "they got off topic and told me im wrong, so lock the thread!" Maybe you don't spend much time on forums...this forum is VERY polite compared to others.

 

Folks, keep the tone down and focus on the topic at hand while respecting others' views and opinions. While opinions from anyone are still welcome in this thread, let's keep the focus on ownership feedback and their experiences, as per the OP's initial post.

To avoid any confusion, I have renamed this thread accordingly.

 

getting back to the original topic. As mentioned - most luxury vehicles that prefer premium fuel have computers that can adjust the octane level from the gas chosen. The difference is that you may not ahcieve the true performance numbers that are published.

For example if the published numbers are 235hp and 258 torque you may only get that with premium fuel. regular fuel may receive a lower output. Maybe only 210 hp and 225 torque (just guessing what the difference will be).

In the past without these computer adjustments you would experience knocking in the engine.

 

Back on topic for me as well... I have no issue with the NX using premium fuel, but its predecessor in my garage (a 2001 Acura CL Type S that I truly loved but was getting a little long in the tooth) used premium fuel as well, so it's nothing new to me.

Count me among those who will not be trying a lesser octane fuel.

 

Here in northern Ohio premium fuel costs about 40 cents more than regular 87 octane fuel.
For the longest time it was only 10 cents between grades, until recent years.
I wonder if this spread is only true in Ohio?

 

In Georgia and Tennessee - both places I am frequently in - the spread is 40-50 cents.

 

.40-.55 difference in my area which is a ripoff.
Bigger profit to make up for the cheap 87 cost.

 

Just got a NX200t from a 2006 RX 330 so I was used to the fuel deal. Like running premium anyway so no big deal.

 

I did a compromise with my RX's and used the mid-grade fuel. I had no engine problems using it and it made the cost reasonable.

 

just wanted to share a couple of screen shots from the manuals on the NX 200t and 300h.

200t -


300h


seems to be a lot of confusion as to what fuel should be used in the NX. hope this clears it up.

 

mwl7698. This thread is to provide feedback for those who have or are considering putting 87 octane fuel in their 200t knowing that 91 is required.

Thanks nonetheless for the screenshots.

 

I think something should be added to this:

Those who wish to run 87 in their car that recommends 91 should detail what their level of car knowledge is. Do they have experience with engine building? Have they worked with engine tuning beforehand? Perhaps worked in the car industry. Heck...even taken an ICE class in college.

I sense a lot of this is the blind leading the blind.

No offense to anyone, but I'm not really going to credit someone who sits and watches Top Gear and feels thats enough to starting suggesting engine information.

With that said, I am dropping out of this conversation. there seems to be a feeling that if its "runs" its ok, and coming from a LOT of engine building experience, i can't help but laugh. All over .50 cents a gallon saved. smh

 

It's nothing to get too worked up over. This discussion goes on on a lot of forums.
