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
