So the car needs to be tuned for it. I can't just put it in and try it?

I wouldn't worry about 94 or 91 on stock tune and you can fill 94 on stock tune. However, if you car is only tuned with 94, then you stuck with 94 and really the only problem with it is it's not available everywhere. When my car with stock and I tried comparing the two gas. I noticed the car lasted longer with shell 91 but I got better throttle response with 94 (got 80km less to a tank). At the end, use whatever you personally like as long as the octane rating is 91 (premium) you got to go

Tuning for 94 is fine if 94 is available in your area. If you travel outside your area and only 87 is available then you have two choices: a) Fill with 87 and carry on with no effect on the engine except timing will be retarded if the engine detects knock or b) tow your car to a gas station with 94. I know what I would do.

had that problem on my road trip. in fact some boonie area only had 'regular or supreme'...


i carried some octane booster on long hauls outside of major cities just to be on the safe side. last thing i want is pew pew lazors to happen inside my engine :icon17:

I had my car tuned in the US with Sunoco 93 octane. Here I use PetroCan Ultra 94. When I was in California and needed gas I switched maps to my 91 octane map and used Shell 91. If you have a custom tune get a 91 octane map. It's a piece of cake for the tuner to do.

If you're running a stock tune, you can switch between 91 and 94 octane without issue.

this all the way... when i get a tune i'd definitely want to have 4maps... 91 tune, 94 tune, valet, blow engine

That's how mine was tuned. :tup:

However instead of blow engine mine is mapped as a kill switch and you need to change map back to get car to start :tiphat:

Case in point, AB Canada is very short on V-Power right now...found out the hard way today, good thing I still had 1/2 a tank.

Alberta is short on many things right now. Good government, jobs....., but I digress.

Ouch.

Edit- could be worse, you could be living in Ontario.

:)

:icon18:

o wait…………….I am stuck here too! :roflpuke2:

or toronto of all places :shakes head:

oh wait... fml :roflpuke2:

Put some in, only because of V-power shortage. The only thing I noticed so far, is that the exhaust sounds slightly louder.
