If you want to be cheap, you should of bought a Civic.


For real it's $3.00 diff.

 

As an incredibly unscientific experiment, I put 87 in my Scion Tc on my way up north and 93 on my way back down. I believe the trips were comparable as far as distance, speed, temp, etc... On the way up (87) I averaged 24mpg and on the way back (93) I averaged 28 mpg.

4mpg difference * 13g = 52 extra miles = ~2g of gas so I actually saved money buying premium in a car the doesn't even require it.

Like someone above said, its two bucks people!!! I wonder how much money gas companies could save if they only carried premium. Probably enough to charge as much as the regular.

 

the gas mileage you lose and it still seems like you would put slightly more wear on your engine since it would detect the knock THEN correct the timing...would negate you saving 20 cents per gallon. sounds like the 20 cents more per gallon is worth spending. I don't like it much either, but it just comes with the territory. You bought a car that run on 91+ octane. :/

 

Did you use the same brand of gas on both fill ups? I think that due to manufacturers using different additives that using two different brands of gas may have more impact than using two different octanes on your car (assuming the TC only requires 87).

my understanding from someone that worked at ChevronTexaco was that all fuels are the same (unless it's walmart gas or something), but the difference were the additives. I guess you are talking about performance and more engine health at that point?
I say stick with the manual suggested 91+ octane.

 

All 87 Oct. gas comes from the same place.

The diff. is how much additives are injected.

 

i use whatever's recommended by manufacturer:

i.e.
- lawnmower - 87 *
- accord - 87, 89 *
- s2000 - 93
- 911 - 93 *
- ferrari - whatever *

i stop thinking about saving few bucks, rather i think about making more bucks so that i can upgrade to ferrari.

* i don't own currently.

 

cyclon...thats right it isnt a civic...the beauty of the civic is that it gets 34mpg around town on 87. Just bc its less expensive does not mean its not good.

 

 

Didn't say it wasn't as good. The civic is a great car, it's just that it's less sensitive to these things and 5 years later, it will probably less of an issue if you ran cheapo gas in a civic than if you did in our cars.
