My '05 SONATA with the 2.7 V6 accelerates very nicely at 87 octane; it's designed to run on 87 octane. No need to spend the extra $.10 per gallon for 89 octane. I've never had a problem merging into traffic, even accelerating up to 80 just because some inconsiderate driver wouldn't back off for 2 seconds to let another car in.
But then maybe your rt 128 is a different rt 128 than somewhere else, wherever rt 128 is.

Thanks for your input but I fail to see the point of the post for the following reasons:
1. I don't and never have merged on Rt 128 and I don't even know where it is.
2. I have never stated I am or was unhappy with the performance of the 2.7 V-6 we had owned. Since we no longer own it it is a moot point.
3. I am not in currently the market for a car "with a bigger engine" OR a Honda CR-V. I wasn't asking for your or anyone elses opinion about which car or engine I should buy.
This started out to be my opinion about the uselessness of using a higher grade fuel than stated by the manufacturer and somehow now I have an argument about merging on Rt 128?
If you feel better about your merge using premium by all means..go for it!!

I thought this was about premium gas, you did mention a Santa Fe 2.7, I said the same retuned engine in a 2007 with more horse power gets better acceleration with 89 or higher.
Around town 87 may be okay, not on the highway. 128 is in Boston, it's the same for merging on any highway in a major city which Boston is.
The manual for my 2007 says for better performance use 91 or higher, I find it to be true.
Whether or not you own the car you are still saying other than 87 is a waste, on most cars it probably is, not on this particular Hyundai in my opinion.

Missing gas filler neck door on 07 Sonata?
by hemi69charger

While filling up, I recently discovered that my 07 Sonata Limited doesn't have an "inner" door at the top of the gas tank filler neck. On all the other cars I've owned, I'd see a metal "door" that covers the filler neck once the gas cap is removed. I believe that door functions to prevent gas from the tank from splashing out. Can anyone who owns a 06 or 07 Sonata verify whether the inner door exists for me? Thanks in advance!

No "inner door" here, either. I'm not certain, but I think those were put in as an anti-theft/siphoning measure. Gas theft used to be a big problem. Probably too much work for thieves now, they steal directly from the gas pump by driving off without paying. Or use stolen credit cards. Anyway, no need to worry. Enjoy your ride.

Thanks, wanna_azzy, for checking things out for me! I doubt the purpose of the "inner door" is for theft prevention, though. I think thieves can still siphone the gas given that the door is there, much the same way that the door can be pushed in (to open) when you insert a tube, e.g., the gas pump nozzle. I remembered reading somewhere--from my Intrepid manual (?)--that the door is referred to as a splash guard of some sort, but I could be wrong. Anyhow, it's good to know that I'm not missing anything. Thanks again!

I think that inner door or flap a couple of inches or so down inside filler neck was originally a functional feature that prevented leaded fuel filler nozzles (which were larger) from being inserted in "unleaded only" vehicles. Since unleaded fuel nozzles are slim only they could be used. Now long after leaded fuel has disappeared this feature has also, it seems, disappeared. That said I haven't bothered to look on our 2006 Civic to see if still has one but if it does I don't know the current function. Couldn't be splash back prevention, at least while filling because the door is open at that point..no?

That flap is only a splash guard to prevent gas from sloshing out while the car is in motion. An anti-siphon feature would be a mesh screen in the filler neck that lets gas in as you fill up but blocks a hose inserted down the opening.

The splash guard idea would only be necessary if someone filled the tank to over-capacity (and only even then until you burned off a gallon or so) plus the screw on cap seals the tank and makes it a closed system for emission reasons. Over capacity is, not only filling the tank but also filling the filler tube to the top. Since this is a no-no with modern cars one shouldn't be doing it anyhow. So I am still at a loss to explain that flap...if it is still there on the newest cars and apparantly the 2007 Sonata (at least) doesn't have it. Maybe it is finally being phased out?
