What's your favorite gas station?

I've been racking my brain trying to figure it out..... the only turbo SUVs I can think of is.... Porsche Cayenne Turbo or Acura RDX?

Mazda CX-7. DISI Turbo 2.3L.

Here we go another fuel war thread of 94octane vs no ethanol people, does not matter on what forum this goes on, its atleast a 5 pages argument everytime.

lol it went from favourite gas station to favourite octane rating.

Hey Primal,


I run aviation gas in my chainsaw, snow blower and lawnmower...now my 16 inch chainsaw can cut a 20 inch log in one cut, my snowblower blows snow back to the north pole and my lawnmower cuts my half acre lot in a single swath ( and its cordless!)

My neighbour let me drive his: http://www.thetruthaboutcars.com/2008/06/2008-volkswagen-touareg-v10-tdi-review/

Super fun to drive, turbo V10 woot.

ultramar, it's cheap

Shell V-Power in the car (ECU can accept 91 and advance timing), and typically Shell 89 in the bike because it doesn't require premium. I did however fill the bike to the brim with V-Power/91 when dumping sta-bil in for the winter/storage.

To the poster who said even V-Power contains 10% ethanol I'd like to know where you heard or read that -- All the pumps I use clearly state Shell 87 = up to 10%, Shell 89 = up to 5%, Shell 91 = no ethanol -- which would mean false advertising. Arguably it is also the reason why I put 89 in the bike vs 87 -- to effectively cut the ethanol in half.

It's not true. v-power 91 contains no ethanol.

Shell V-Power 91 octane premium gasoline does not contain ethanol all over Canada.

Interesting, thanks.

Had no idea Mazda installed the turbo engine from the Mazdaspeed 3 and 6 in the CX-7.

-Jamie M.

That's cool because I always wondered why it said "where available". My understanding was that there was some ethanol in some gas stations.

 

[binette88]

shell and petro canada shell no ethenol and petro no ethenol and 94 pure

 

[binette88]

Ummm, no? lol. Ethanol contains less energy potential than gasoline and no 94 is ethanol free, so right off the bat ANY 94 octane fuel will have less power than Shell 91 or Ultramar 91.

-Jamie M.

I did not know that!!.. good to know might as well jus grab shell instead of missions to find petro

You're right that octane rating itself is not a measure of performance or power but it will be most resistant to engine knock. If your ECU is able to detect this and take advantage of the high octane fuel, it can advance the timing to effectively increase compression and torque. Again, it's all dependant on the ECU mapping. Some may detect it, some may not, and some may take many many fill-ups before it switches maps. Is the power increase worth it? Probably not unless you're on the track. Fuel with higher ethanol concentration is also quite hard on the fuel system and will require more of it to be burned to produce more power than ethanol free fuel.

That isnt totally correct onlctane is a fuels ability to resist detonation, therefore higher compression ratios require higher octane. It must be compressed more before it will ignite for that reason. For example I have a small hobby engine with adjustable compression domes when i use the 16:1 compression ratio done I need to use 112-116 octane racing fuel. When I use the 13:1 dome I can run premium pump gas.

Octane only equals power if you have a high enough compression ratio in your engine to run it. Running high octane fuel in a low compression ratio will not give you any power, it will give you less and can cause damage or engine failure

Ethanol is just crap added to fuel, it's poison

You're right, octane is a measure of ability to resist detonation. Engine knocking, although a technically different principle can be induced by using too low of an octane gas than recommended. Using too low an octane fuel can cause the flame during the combustion process to hit the top of the piston too soon. The crank angle will not be at optimum angle on the downward stroke. This can result in engine ping. For vehicles that have the compression ratio to take advantage of higher octane gas, the ECU can advance the timing to allow the combustion process to develop peak power at the ideal time to effectively increase torque.
