I actually just tried switching between a tank of 91 and 94 this month for sh*ts and giggles, and maybe its just my “butt dyno” but I can feel a pretty big difference.
where are you located? Ontario? AB?
your stock tune (fi you are on stock tune) will probably pull timing on 91, but on 94 it will be able to use a bit more. Bit more power. Although in the cold, car should be using the stock timing pretty well up. 91 can suck so it’s tough to say. 94 + cold = great things from my car relative to 91 in the summer.
Vancouver, BC. I have a 93 tune (count said it was actually specifically for 94, but the invoice says 93). Is your 94 chevron? I love that stuff, the only other people I see using it are crotch rockets
It was about the same as any other place with about 30 cent difference between 87 to 93, but then 91 to 92 to 93 was a 4/5 cent difference. It was nuts.
The 92 is for the cheapskates that know their car requires 93, but they want to save 5 cents and assume it won’t make a difference since it’s only 1 lower. I have seen a guy with a new Mercedes CLS put 89 in his car. My mind was blown
Gah, drives me crazy, if your car recommends 93, use 93 or buy a different car… especially if you are driving a new Mercedes, I’m sure you can afford it…
Yea, like I said, I was blown away when I saw it, thus the picture.
Most places around me do 87 91 93, so I put 87 in the Jeep wherever I can find it and 93 from Shell in the Audi.
It’s pretty comical when you look at how little money you’re saving per year for cheeping out on gas. It’s not nearly as much as most people think. Getting gas prices back down though, that’s where some real savings should be had, and there’s no reason for them continue their escalating path.
Yea it’s definitely pricier, and like I said maybe it’s all in my head but the car seems to absolutely love it. There’s a lot of local guys who don’t go on the forums with big turbo builds who are tuned for 94 around here, and those cars are craaazy.
I think it’s more complicated than that, b/c of the subsidizing for farmers to grow ethanol in the first place. And the cost of manufacturing ethanol from any crop is an added expense in comparison to the traditional refinery of crude oil. Not saying our government would find a way to add a tax and drive up gas with less ethanol being used, but there is argument on both sides and if ethanol had never begun in the first place, I’d have to think overall cost/price would be less.
Man I wish AB had Chevron 94. All we have is Husky 94 with ethanol. I’ll probably still run it when I get the JHM 93 tune. Keaton figured it wouldnt be an issue and I’d still see power increases over the 91 tune.
I think you would for sure. I’d love to see some hard data on the difference between a 91 and 93 JHM tune. Take a car to the track, run with a 91 ecu, swap it, TB reset, run 93 ecu?
