Canadian maintenance schedule

[Hockster]

One of the local car groups here had a guy test the chevron 94, it turned out to be ethanol free as well, but there's reports on these forums that it's crappy quality. There's only 1 Chevron in town and I've never tried it.

For having tried it before with my Stinger GT Limited, using 87 octane fuel did work without any issues. But the power and torque were indeed reduced and fuel economy also suffered when compared to 91 octane. So I went back to using premium.

I put Motul 5w40 in mine after I broke it in at 4000 km. I intend on changing it every 6 months since I do not put many km on my car. That will always be below the 6000 km range. As far as gas, in eastern Quebec we only have 91 octane, so I fuel up at costco or Shell only. I sometime put a can of booster that brings me up to 98 octane. The car is strong and wicked smooth when I do that.

Motul and Molly are great choices , I have use both and they run well

To add to "additives" point it is also what isn't in the fuel - Shell's premium fuel is the only one (that I know of) in Canada that has zero ethanol. Ethanol isnt good for direct injection engines as I understand (high moisture content) so that's the only fuel I will be using. (Unless someone knows better than me) As for the cost? A little week by week is better than one big bill and if you have or sign up for Air miles you save $0.03/L and can use your points for free fuel, car washes, etc to help offset the cost

I saw a video that showed wear on engine parts, and other issues of gasoline, E10, pure Ethanol and methanol, and the E10 was fine for wear.
It did mention that it caused a bit of water in the oil, but I believe it said if it sat for a long time and not so much if car runs daily/regularly.

What reports have you seen that suggests that E10 is not good for gdi engines ? Please share, if you can find these reports.
If true for sure, I'd like to know so I don't use it and watch out for this at stations.
I usually use Shell or the Ultramar that has Premium at 89 prices on thursdays.

I read so many things about DI, turbos (the Stinger is my first turbo car) catch cans, etc that I may have mixed messages, this wheels article mentions it, with the caveat that your car may not be able to take advantage of the performance in the fuel

...Ultramar that has Premium at 89 prices on thursdays.

On Thursdays and Fridays here in Montreal, Quebec.

So our engine's are 10:1 compression ratio. I've heard it be said this car has high compression ration, but that's not on the high side ?

side note, my gt limited has the 5w 30 oil cap w/red letters.

I've heard it be said this car has high compression ration, but that's not on the high side ?

Forced induction engines have a lower static compression ratio because the FI pushes the effective compression ratio well beyond that point.

Computer management is pushing the limits ever higher, but 10:1 is a pretty decent starting point for a twin-turbo motor.

Supposedly Costco premium is ethanol free as well. Mind you this link is from 2017.

Can confirm, Costco 91 is ethanol free and Top Tier detergent gasoline. Have only been using Costco premium for my car since I picked it up in October

 

[Hockster]

Heard a rumor the Canadian Tire premium was ethanol free. Sent an email asking over the weekend and got a response today that it is indeed ethanol free.

"Thank you for contacting Canadian Tire Corporate Customer Relations.

question is, area ALL Gasolines sold in Canada, regardless of brand, meet said requirements ? LIkely do, otherwise they'd be closed down.
question 2 is, what are the requirements and 2b, are they too low or are the stds high enougth that all fuel in Canada is good enough for our cars ?

And if new turbo engines have sensors and stuff that sense the octane being uses and changes the mixture so it'll NOT Knock, then why isn't safe to use 87 octane ? Kia says it's safe to do so, but some folks say it's still not good for the engine in the long run ?
What is the actual science ? I'm testing both now

Why all the concern around this? Canada isn't some 3rd world country or something. Just buy 91octane or higher at your local reputable gas station and you're good to go. Why anyone would buy a performance car with a TTV6 and run anything but high test is mind boggling to me.

 

[Hockster]

Running 87 might be safe, but even in the manual it says reduced performance and mileage.

 

[TheAlien666]

Having tried it myself, using 87 octane gasoline I didn't have any issues aside from the reduced fuel economy and performance. But the car didn't feel as sluggish as I would have thought, just a little less prime. But the gas tank sure didn't last very long, so the money saved on regular fuel was negated by the fact that I did much less mileage with it. So I went back to using premium (91).

 

[MerlintheMad]

True. And as one guru said in his video, "Why not avoid engine knock to begin with?" If the car adjusts to avoid knock, that means that the engine was beginning to knock, and modern tech compensated. But why allow even an incipient knock when it can be avoided altogether?

 

[I Stung U]

I don't think it adjusts as a reaction to knock, but it senses the octane level, somehow, I think, and makes adjustments on the fly or within reasonable time of driving with it ?
If it's a reaction to knock, then no questions anymore. If it's before cause it senses it and it's and if it really is safe to use it, then I would, to save money.
I've already done some testing with it, and I do get a wee bit less mileage but the price difference, it's still noticeably cheaper $ per mile on 87 octane, and same type of testing by many pros out there, says the same thing It's cheaper per mile cost to use the 87 octane.

I've haven't the time to do more research on here, which I will do .
Anyone here have any good pro video links to post regarding this, I'm open to seeing them.

I don't trust manufacturers to be accurate on this, cause if it's already been proven that gdi engines can have LSPI (low speed pre-ignition) happening which damages the engine, them knowing this and ONLY recommending oil that meets only ISLAC GF and API SM only, this would suggest that they're stupid or aholes who want you to blow the engine, to make money from you later.
This engine oil issue is a give away they're either stupid or crooked. Top Engineers are aware of LSPI, and they know new oils are designed to help reduce the lspi issue, why wouldn't they update their min. oil. recommendations ?

Side note, any one find the get either good or worse milage with Costco gas ? 87 or 91 ?

Top Tier is Top Tier. I use Shell when I can't find Costco.
