Guys, what octane does the Series II 3800 engine like more?

I notice my car has much better fuel consumption with the 91 octane Shell V-Power which is pure gasoline and whatnot, car seems to run a little smoother maybe.

However, it seems to me, I have more explosive power with the 94 octane with 10% ethanol added, I am not 100% sure though.

I have a few questions.

Ethanol... what's the deal with ethanol, it's not 'good' for the engine is it? I know it has a high octane rating but other than that, is it possibly harmful?

I remember reading on GP forum of a guy who said he will never put any gas mixed with ethanol like Sunoco or Petro Canada do with their 94 octane, and he would rather run 91 octane with no ethanol.

Any ideas guys?

I'm still not sure what gas to use longterm... Shell V power 91 or Petro Canada 94.

Would going WOT on the highway with each gas, and seeing how many lbs of boost I get, be a good indicator of what gas is better? Making sure, that of course temperature is abou the same on both test days, or is that pointless?

Let's hear everyones thoughts on using 91 vs 94 with ethanol :)

tried both, tracked the fuel mileage, similar driving conditions and found that my car likes the 91. KR didn't change much, a tad lower maybe with the 91. and its a couple pennies a litre cheaper.

I would say pointless.
Too many variables with going WOT & temps & such to use boost as an inticator.
Calculations real ones, not DIC. would be the best for over all MPG.
For performance Track times or something that could measure 0-60 MPH times.
I thought I read somewhere tht ethonal changes the fuel ratio or we need to change "that 14.7 to 1" ratio with a tuner for best performance/KR/MPG.
Just my 0.02

Ethanol is basically alcohol (rated at around 105-110 octane). It will get you more power but less gas mileage. So a little less KR (burns cooler I believe :think:) You will lose some number of MPG. Here in Minnesota a lot of the high HP guys tune and run for the E-85. They are able to run a little more stable with pulleys around 2.8 and 2.6 size. I have rode in a 11 second GP running E-85 and it will blow your balls off! >-) It also smells like Race gas

ABStiffGS's Regal was in the 11's on E85 and it smelled like corn...

Ethanol burns cooler (reducing KR), but releases fewer BTU's meaning less power per unit compared to gasoline (lower MPG). Gasoline companies add Ethanol inorder to use lower octane gasoline with Ethanol pumping up the octane.

As far as the OP's question... I always choose non-ethanol, even with the higher octane 10% stuff. However, I don't think either of us are pushing enough HP or fine tuning enough to make a difference.

I liked the good old days when you could get 93 or 94 octane where there was no ethanol in it... The best of both worlds.

To the OP if you live in ontario imo the sunoco 94 is crap. Shell 91 Is the only thing I'll put in my tank. No exceptions. I can't speak for your 94 octane gas if your from the states. all i know is that in ontario the best gas you can get is shell 91

Im in Montreal.

I think Sunoco 94 is pretty much the same as Petro Canada 94.

Yeah Ill keep 91 V-power, thanks guys :_)

Never mind the clerk, look for the sticker on the pump. By law there should be on there.

Gas pumps are supposed to place the ethanol percentage somewhere where you can see it. In NY almost alll the stations say may contain up to 10% ethanol

Now my problem with that is, since we used to have Mobile being the only one NOT using ethenal, it was more expensive. Sunnoco was cheaper , offered 93 octane and had up to 10% ethanol.

Now both Mobile and Sunnoco are no longer 100% gas. As well as BP, Noco, Getty and tops etc... so anyone looking for pure gas in WNY is kinda out of luck.

It's pretty much the same up here in Ontario...it's called "Industry Standard" and again, it's pretty much a continental thing.
