Gasoline Brand Preference

I look for the best price.............. BP, Shell, Clark, Mobil

 

Interesting expose on higher octane marketing:

Pump Fiction - Marketplace

I favour Chevron (regular octane), mainly just latched onto a brand, and figure it's one less variable (if there is any variation), if I'm monitoring mpg. Also, they have free air, about the only brand in our area.

 

Costco has been good for me. I might try chevron on the next Fill up

 

Costco and Sam's seem to hurt my MPG..............

 

Costco all the way with new "TopTier" additives.

 

I thought Costco gas wasn't top tier. Where did you get that info?

According to a pamphlet at Arco stations, their gas is equivalent to top tier.

Galaxy Nexus ? 4

 

Here's my Costco mpg

 

^ Helps to have a bigger battery, huh?

 

I think you might be right but I don't think I would see substantial gains with chevron. I think it's all in the mind when it comes to which brand name gas is better.

 

Sweet thanks! that will save me even more money now... the price difference between regular and mid grade is sometimes almost 20¢

 

All fuels will cause deposits. IMO, anything other than BG,Chevron Techron, or the 3M chemicals are snake oil

 

Sounds like one of those interweb legends with no real basis in fact.

There's no evidence that use of injector cleaners has value on ANY car, even less likely on a Prius. Earlier injector technology and fuels might have been a different situation. Chevron with Techron has been shown to accomplish adequate cleaning. Note that Texaco with Techron is the same gas.

 

I have plenty You might be assuming this and touting it as truth, but it's NOT even close.

 

FreeRide, it looks like you've embedded your response in a quote, anyway:

Going from 57 mpg to around 65 mpg is roughly 10% improvement. I can't see this: if legislation adding a 10% gas additive cut mileage by 10%, there'd be torches and pitchforks in the street, LOL.

​

 

Are you saying (1) no detergent additives are needed for any reason, ever for Prius, or are you saying (2) some detergent additives help but for other reasons besides injectors? If detergent are not needed, then Techron is not needed, right? I am under the impression EPA requires a certain minimum level of detergent additive, and TopTier.com gasolines contain more than the EPA minimum if needed to achieve the optimum level of detergency.

 

good find... i must have mis-read it or have been thinking of my wife Ford Edge when i posted. I brain is on over drive during the day bc i am trying to chat here and work at the same time.

 

i was just digging around on the Toyota Owners website and looking through the manual and here is where i got my info...
