Premium only.

It actually makes me tired that people always want to test things with their cheapness. Can u put regular in? Thanks to smart ECU, u can. Is it recommended? No. Why? Well, I lost 30-40 miles per tank. At the pump, the difference is usually no more than $3.

I have not seen dynos that would show how much TSX loses on performance side, but early models of 350Z lost 16HP and roughly as much torque by switching to regular gas.

Bottom line: fill up with regular and you lose both performance and long run on a single tank and u dont save shit.

premium, because for me its only about 3$ more for a full tank.

i just LOLed. i only use premium also

Yes, try pumping half Premium Shell V-Power and half Premium Chevron Tectron so together you can have VTEC Gas to match with your VTEC engine! :mardi:

Premium only. And only from Chevron or QT if possible.

My dad on the other hand puts 87 or 89 in his 08 TL-S. :rotz: Different engine i know but still.

Shell Premium

It's especially important to use Premium (91 octane or higher) with the Hondata reflash.

The reflash advances the ignition timing so if regular gas is used, the knock sensors/ECU would really pull back the timing.

My 06 is completely stock, I do mostly highway driving on flat roads. I do not race or tow so for me regular gas works. For the 1st 2 months I used premium than switched to regular. My car now has 110,000+problem free miles. I have all the service done by acura/honda dealers and get complimented on how well my car is maintained.

if i was a girl i would get complimented as well :laugh:

but anyway, i use premium all the time, and sometimes 105(Racing gas)

shell v-power 99 ron like whoa!

 

[whatsanacura]

Premium here as well, as stated regular will also lower your gas mileage.

I also always use premium. It's only $.20 more a gallon, which translates to $3-4 a tank. No big deal.

I know the manual says to use premium gas, but the engine is basically almost the same as accord's and its i4 with only 200hp. Do we really need to use premium gas? or do you guys just use regular? Thanks

i lol'd...how many other stock 4-cylinder engines do you know that have 200hp??

nissan sentra se-r... also has more torque than us... just saying...

on topic: i always use premium. chevron w/techron 92 octane. always. i don't believe in being cheap when it comes to car maintenance and longevity...

I always use shell v-power 91, anything alts and the car runs like shit. I just wish there was 93 or 94 around here.

 

[woogi8]

yes, i do!

 

[Fars]

93 always
