Fuel Grade - what do you use?

[lesnar]

Which fuel grade do you guys use (regardless of what the Car Owner Manual says).

If the reasons for using a specific grade is not listed in the poll please specify.

Please also note the car that your driving.

"i FEEL that car performs better" translates into "I get the placebo effect"

When I had my first car (back in 1988) I'd get the Sunoco Gold about half the time (it was the highest octane at the time - 93 or 94 I think).
I don't have a car now, but I think I'd just get the regular if I did (way cheaper).
Looking back, I think I was wasting my money as my car had a 68 hp engine (1988 Dodge Colt). It was a small output engine, but it had good pep, no matter what fuel I put in it. Weighed only 1,850 lbs!
The difference between regular and premium was a lot less than it is now.

There's no reason to use premium unless your car requires it. That being said, I once filled up with premium at a Shell station that ran out of regular (it was the same price as regular and the mid-grade wasn't available because its a mix of regular and premium)....and I swear I got better mileage. But most likely it was the placebo effect.

Why is there no option for octane 94?

[MP3_SKY]

91, recommended because of my advanced ECU

[bembol]

Not only I FEEL my ride ('02 Acura RSX) run smoother...I do get better milage, about 30kk+ compared to Regular. Also, I figure I'm spending $40 for Castrol German Syntec 0W-30...

I use Esso Supreme because of Points for Touchless Car Wash during Winter.

87 Regular ftw.

ya, i heard if you use the higher grade it will give you better gas mileage (been tested by a few buddy of mine who filled up their tank and drove until the Empty light is on - they have tried it a numerous time).

So is it actually worth it in the long run - advantages: better gas mileage, possibly better for your car...??? what do you guys think.

Has anyone heard about Disadvantages of using better gas grade besides the cost..??????

[afzan]

i get 94 instead of the 91 my car requires.. i get an extra 50km+ per tank out of 94

[Spray]

need a 94 option...that's all my car is programmed for.

[plucky duck]

I beleive my 5th gen Prelude requires 92 Premium, but I find I've been getting decent mileage on Shell 91. Haven't really monitored mileage on Husky 94 before.

[EH100501AC]

Ha! First vote for 89.

You almost missed 94 Octane but yeah.

[Samir]

Where aside from Petro-Canada can you buy 94?

Just curious, I've never seen it anywhere else.

87 for me, btw.

[Evil Techie]

chevron's 92 for my car cause it needs it
otherwise shell's 91
