Loss of power after gassin up HELP!!!!
 

Filled up 91 v power on Tuesday and car hasn't been the same..could it be a bad batch of gas....Car has 4000km on and no oil change done...

i think the car is recommended for 93 or higher octane. Petro canada offers 94 octane racing fuel, i suggest u use that instead of 91. the price for it isnt that much more that 91.

did or does it still chirp? people were saying that thanks to the lack of ethanol in 91 V power that it eliminated the chirping from the direct injection.

no chirping >> extra power ??

Try a bottle of octane booster to up the octane level and get you through this tank of gas.

It's possible the gas station dumped the wrong grade of gas into the wrong well? It's possible that it's just a bad bit of gas..

I wouldn't stress too much until you've emptied this tank and refilled... or if you see a check engine light come on or something like that.

There is a huge different in performance between 91 and 94 octane. I can notice the different on the FRS but not on all my previous car.

The noise have nothing to do with power

I've been driving around Tdot as we speak...I'm almost a quarter..should I wait till the light comes on until I put 94 or a quarter is fine ..

That's cuz the car was designed for 93 octane with 91 being acceptable.

your other cars were probably designed for use with regular fuel (87 octane).
The higher octane wouldnt give much benefit to those engines.

I'd stay away from Petro 94. The octane boost comes directly from an ethanol injection, hence the chirping sound. The power boost (if any) is negligible. I just went back to Shell 91 after two tanks of Petro 94 and the chirping was persistent enough to be worrisome/annoying.

My previous cars are S2000, RSX Type S and integra with B16(winter beater), all cars call for premium fuel.

Do we still have sunoco ultra 94 in GTA

That's what warranty is for. LOL
If lots of people complain or failing. Toyota/Subaru Will come up with a improve DI pump and would have TSB or RECALL.

Yeah except they're called Petro Can stations. Sunoco and Petro merged with Petro being their retail brand. Their 94 is the old Sunoco 94.

And I second all those who are using 91V over Petro 94. If it was true ethanol free 94 then yeah it would be better but Shell 91V ethanol free is much better quality gas. And the negligible power loss(were talking 2-3 horses people!) is worth it versus the long term use of ethanol additive any day to me!

I believe all gasoline have ethanol now, doesnt matter is Shell or others. According to this statement from petro-canada website.

Ethanol-blended gasoline is a fuel that typically contains up to 10% ethanol in unleaded gasoline. We use ethanol in our gasoline where legislation requires its use and where conditions warrant. The Federal Government has regulated that motor gasoline sold in Canada after Sept. 1, 2010 must contain an annual pool average of 5% ethanol. Different provincial mandates also exist, some with higher ethanol pool requirements. Because of these mandates, most grades of Petro-Canada fuel may now contain up to 10% ethanol. This represents a change from the previous state, where premium fuel was ethanol-free at Petro-Canada. To find out if ethanol-blended gasoline is sold at a station look for the yellow labels in the pump area indicating that the fuel may contain a maximum of 10% ethanol.
