arco gas?
 

I've filled my previous car with arco and never had trouble but my friend kept telling me to not use it. Now that I have my z i'm a lot more curious as to what type of gas people use. So the370z please let me know what type of gas you fill your z with. (of course I use premium) thanks.

I'm typically not the type to defer to old threads but this one has literally been covered to death. Google "the370z fuel" and you will get several. Go through until you find the answer you are looking for.

I've put Arco (premium only) to my Z for years and no problem at all. Even now the Arco is in top tiers.

thanks for the reply felix0121

You're welcome. I also get a lot of useful informations from this forum.

Let me explain what I've experienced more in detail. I had purchased my Z in the early 2012, and from the first I just had put the cheapest gas as found anywhere nearby. At that time I had no idea about the fuel additives, I just wanted to pay less as possible for very expensive gas prices at that time. (It included Arco, but I must have visited many non-top tier cheap gas stations I guess - of course always premium though :rolleyes: )

Later one day I found out I got to have somewhat lower throttle on my Z especially when I try full acceleration for zero to sixty entering freeway from local. So what I did was that I put a Valvoline and Techron (by the Chevron you know) engine system cleaner to my Z, and very soon I got back its whole faster response as I had at the first time.

My last report from Blackstone says the engine looks in pretty good condition now.

By myself I've tested many brands of premium gas (like 76, Shell, Chevron, Mobil .. etc) to my Z, but as a result interestingly I found out that I had the best performance with Arco premium (it is by my subjective feeling, not by any objective measure). If it is true, it must be because my engine already got used to the Arco gas, so other Zs might go different.

As I know any engine is supposed to get used to a specific brand of gasoline because of its different additives. I think Arco gas is okay, but what matters is that you really need to put high octane - I mean premium gas to your Z.

I agree Shell or Chevron are more expensive and maybe better than Arco, but absolutely Arco premiums should work far better than those regulars on your Z.

Or if you want to take care of your engine better, you can also try those engine system cleaners. I cannot guarantee it would work to your engine, but it really worked to mine when it was little messed up with putting cheap gas. (I recommend you to be careful to choose what engine cleaner to use, because bad cleaners might do harm to your engine)

arco gas?
 

Do NOT buy arco! There's a reason why it's so damned cheap! Haha you get what you pay for. I would suggest any of the following 3 in this order 1. Chevron 2.shell Vpower & 3. Mobil 1, 91 octane obviously :)

Arco gas claims its top tier but I've compared the way my cars run with all 4 stations and I am the happiest with chevron. I noticed better throttle response, tank duration, and just overall smoothness of power output :)

:eek:

I prefer 93 octane ;) :driving:

Unfortunately there's like no where with 93 octanes unless I buy a booster every fill up :/

Oh I know. Another reason TX > CA :stirthepot:

I'm just joking around of course :)

Lmao yeah I hear some states do carry 93 octane which is BS! If Cali has the strictest emissions laws then why not provide cleaner gas with better octanes?!

I would like to hear your thoughts on 76.

You know I don't think 76 gas is actually bad, I've always felt like 76 and shell kind of go at each other and Mobil 1 and chevron are head to head. Of course I still trust chevron over any other but I'm not sure I tested 76...

Guess I've never really been that drawn to it :/ sorry man I'd love to elaborate more but I don't have enough experience with it to give you a good, quality, honest opinion at the time. Maybe I'll decide to try it a couple of times just to give feedback haha.

I've been buying gas for over 40 years and, as far as I can tell, there's not enough difference in the major brands to worry about. The condition of the stations' tanks has a much greater effect on gas quality than the brand. YMMV

Thanks man. I usually stick with mobile or chevron myself haha. But used 76 past couple fill ups. Most threads I found on it said it was up there with the rest. But idk why always felt a lil iffy about them xD

My dad won't use shell or arco cuz apparently he's gotten bad gas at those places in the past and caused major problem. But meh

a bunch of our shells are becoming VP Racing fuel

speaking of which doesn't CA have 100 at the pump?kinda jealous

Yeah I fell the same hahaha pretty much why I haven't given them a go X) but dude try it out your self. Fill up maybe half a tank of arco and burn through that. Pay extra attention to everything. How well the car picks up speed, launch behavior and overall smoothness of power gain. And then do the same with the Chevron, or other gas of your choice, and give it a little test :) you SHOULD notice a slight difference. I've felt my BMW and Z be sluggish when using arco and other not so popular brands.

But again that's just me brotha don't take my word for it try it your self! :)

i was hoping after ur long post dat you'd put ;) jk at the end..

Dear Thor! Where did you seen that!? Hahaha I gotta go now! Lol I've heard of a couple of rare stations that do carry it but it's like legendary **** that you need a master ball for! Hahaha they're out there but requires ridiculous travel times and maybe elevated costs and I think it's considered like for racing only. Not sure how it all goes down...

Placebo effect. Retail gas all comes from the same refineries. The only difference is the additive packages like techron, etc.

Lmfao! That'd be solid cash!

:rofl2:

Haha just found my nearest station with 100 octanes it's 143 miles away from me and it costs $9.93 for 9/10 of a gal. Hahahah yeah by the time I get home I'll have to fill up again XD.

People overthink gas. It all comes from the same place. The thing you should be concerned about is the gas station, not the gas. Are the tanks ok? Does it get enough traffic so the premium doesn't just sit for long periods of time and absorb condensation?

In addition, 99% of octane boosters and fuel treatments don't work. Techron concentrate is one of the few cleaners that makes a difference. Octane boosters might turn your tank of 91 into 91.2. Toluene will boost octane very well, but it's not cheap anymore.

:tup:

We have a refinery in town. It's commonplace to see tankers from the different brands in the area filling up at the same rack.

Mabey some might find this helpful idk

Shell or BP(old Amoco). Chevron does not run well for me. Turbo cars find so so gas real quick. The tanks at the station make a big difference. No old stations for me.

You don't hear about class action lawsuits against Arco, such as people complaining that it ruined their cars, right? Well, then that's where I take it.

I don't think there is any nuance if at all when comparing cheap gas to brands like Mobil or Shell. There is no in-depth analysis that proves this....I could understand if you drove a higher end car $60K+ like a C7 or 991, but c'mon. These are Nissans meant for common people. I used to ride 2-stroke pocket bikes, and guys would buy $30 2-stroke cycle oil versus $6 weed whacker ones, thinking they had "Ferrari engineered" weed whacker, leaf blower motors on their China-made pocket bikes. And it's not like they were faster on the tracks; it just smelled a little better.

To each his own I guess.

#1 Shell
#2 Mobil
#3 Cheveron

I'm with Chuck on this one. It's way more important to get your fuel from a station that clearly has to refill its premium fuel stores frequently.

I have been using Arco 91 octane in my '09 since new. I'll bet it's had less than a dozen tanks of gas from other stations through it. No problems encountered at all. I do add 8 oz of MMO to the tank about every 1000 miles, that seems to help with the sticky fuel level sensor, and I run a bottle of Techron through it before each oil change. Arco is top tier, use with confidence.

In my view,i think big Oil Companies should have more budget for R&D,so their fuel will be better..

I use Arco, Valero, or anything else that is Top Tier. No issues at 60k miles!

Ethanol Free 93 only

chevron or shell

Im in the same boat as the O.P. Before getting my Z I really went wherever they had the lowest price. Since getting the Z I read a little about Top Tier gasoline and decided to try and use only that. I have read some good things about Shell V Power Nitro but the closest one to me is 1/2 hour away. 93 octane always.

Hey fellas,

I work as a chemist for a Valero Refinery, my job is to certify the finished gasoline. We ran a bunch of different tests on the fuel. My primary test is to check the octane rating, whether we're selling 87, 89 or 91. From what I know working in the refinery is that it doesn't matter where the gasoline is coming from...whether Chevron made it, Shell, Arco or Valero. Our gasoline gets hauled to different gasoline stations not just Valero's. Furthermore, a lot of gasoline from different refineries get pooled in what we call Commuter Tanks off site. So you see t doesn't matter who made it but what does matter is the gasoline station you're getting it from. I am told that Chevron with Techron is the best additive you can put in your gas tank, followed by Shell's V-Power. I get a small discount at the Valero pump station here at work...but I still pump Chevron. Anyways, I just wanted to chime in. Thanks
