Is 94 octane really worth it?

Yes it is. Just try a tank full of regular and see just how noisy the engine gets ;-)

I'm currently running 91 octane, so I'm guessing it will be much better for the engine if I run near empty and switch over to 94? 1400km on it currently

another 600 until first oil change yay!

Sorry, I thought you were referring to regular vs 91 or 94 octane. My mistake.

So would you still say I should switch to 94? My car is still basically brand new so if it will be of benefit, Ill make the change.

Chevron 94 with Techron

Living here in the a$$hole of Canada where there's no choice except for 91 octane at any station you choose, I take advantage of the Super Store pumps that give back 3.5 cents/L for groceries. But I've filled up with Sunoco 94 in Ontario last fall. Didn't see any noticeable difference in daily driving.

Is the Superstore gas okay to use? I'm almost ready to bite on a white 2010 370Z and that's where I usually fill up my Jetta because of the money back for groceries.

Yes. Superstore doesn't make gas so they buy it from Esso, Shell, Irving or some other refiner. I haven't heard any ping from engine in 22K kms. So, I'll keep getting my grocery coupons.

I fill up at Husky with 94.

Husky uses 10% ethanol. E-10 is corrosive to steel. Used to be called gasohol.
Basically you're putting moonshine in your tank.

Whoa hold on guys - you are wasting your money running 94 octane. I was under the same delusion for a long time. You get more power out of lower octane fuel but we need to run 91 to keep the engine from knocking because of our high compression. 91 is optimum whereas 94 is only needed if your car is pinging or knocking and if your 370Z is knocking on 91 you have either bad fuel or a problem with your car.... unless of course your car is boosted then you're gonna want to run 94 or higher

I realised that Sunoco 94 Octane doesn't improve any power and also it more expensive than 91 AND I get "less" mileage.

So 94 = more expensive + less milegae + ethanol... I am sticking with Shell 91 as it claims to have 0% ethanol (which I don't think the 370z wants).

So I made the switch to 94 octane... Now it feels like I'm driving a jet plane.
