don't want to start another heated discussion lol, just looking for simple answers.

When I bought the 16 ILX, I used premium (the dealer said regular is fine)......I've been running regular for about 2 months now and the car rides beautiful, smooth, I'm still reaching 38-42 mpg on long trips (pretty much the same)

just wanna know for the long run, if I'm safe using regular? Or should I switch back

<p>and plus, you dont really save money when using a lower octane fuel. The ECU adjusts so that lower power, lower fuel economy to account for the lower octane to prevent knock.&nbsp;</p><p>&nbsp;</p><p>thus why it's &quot;recommended&quot;&nbsp;</p>

Can these threads be banned. It's like the reverse of justin leaving the gates open and all his 3G lackies come through.

Lower octane fuel and the engine will adjust by taking out a few degrees of timing. Yes it will work but with lower-than-rated HP.

Oh mr quality engineer, can you advise why the TLX I traded my ILX in for sucks shit with a terrible 9 speed transmission... transmission shifts are definitely a downgrade.

As an engineer, I am not the correct person to go to for specific complaints/warranty stuff. I was merely stating how I know what I know about these vehicles. I'd be happy to answer whatever spec-related questions I can about the ILX/TLX/Accord.

Can we just auto-lock any thread title involving gas or the word "premium". Please?

No problems with regular thru 36000 miles on our 2013 ILX Tech. Highway average is always over 37 mpg.

Nexx
