Late Wednesday night I stopped at the former Sunoco at Queensway and 427 to fill up, but it has now turned into a Petrocan as a result of the corporate union. I needed gas so I went to fill it and noticed an Ultra 94 pump just like it always was. I guess I'll be stopping at the Petrocans now and watching the stock price hopefully go up.

Anyone know if that has ethanol in it ?

pongobaz

Yup...same **** as the sunoco 94.

10% I think. Rennlist guys got me on to Shell 91 (no corn oil) and I noticed 15% improvement in mileage and no exhaust tip soot.

I only run Shell 91, again bc of the low ethanol content. I try to stay away from other brands unless I'm in desperate need of petrol.

^ now that's interesting. Got to look in to this Shell 91 business.

shell 91 has no ethanol, here's the sticker on their pumps:

So pardon my ignorance but is ethanol bad? Or does it give less performance?
Since I got the P car, I've been using nothing but Sunoco 94, thinking that I was doing the right thing.

I switch between Petro Sunoco 94 and Shell 91. I just filled up with Shell this morning on my way back up north and the car feels gooood!

Well for me ethanol is very bad as it is pretty hard on CIS componenets. I don't think Ethanol is good at all really but i can only speak for myself.

FFaust

Yeah, did a search on RL after my post above... and I'll be trying Shell 91 for the couple next tanks.

I always put PetroCan 94 because I tought octan needed to be higher than 91.. ?

chrenan

I always use Shell 91 as well.

From what I understand, ethanol doesn't burn as well, and can be really hard on non-metal components within the fuel system, in particular in older cars like Clive's or mine. It's very strongly recommended to avoid ethanol in old systems, however in newer systems I don't believe it's quite as harmful. But because it doesn't burn as well, it hampers performance, despite the added octane in sunoco 94. If you want the best of both worlds, use the Shell 91 and add octane yourself - you can buy it at CDN Tire.

What's more is that octane is measured differently in different countries, so when a German car calls for 94 octane, that might be the German rating, which might be the same as 91. I don't know for sure, but I'm fairly certain that back when my car was made there was probably no octane equivalent to Sunoco's 94, so I'm pretty comfortable using just 91.

If you're really curious, google it (or search here) and you'll find way more information than you care to read. I did back in the days when I had spare time (before kids!) and read a fair bit on it. Can't remember most of it now, but I made the decision to stick with Shell 91 based on what I read.

All suncor petroleum products contain 10% ethanol. Sunoco and petro canada.

All BP products contain salt water, mud+concrete mixtures, golf *****+junk mixture.

Shell rocks!!!!!!!!!
