#20 of 24 Re: Top Tier Gas [fezo]

I use top tier gas (Shell V-Power 91) for my wife's Mazda CX-7. I do this for both the detergent in the gas formula as well as the fact that the 2.3L turbo engine has known issues that I'd like to avoid.
No Chevron stations here in Colorado. I know my folks use Chevron in their Hyundai Sonata.
For my ION, however, I use the gas from the local Kroger station. 85 octane and it seems to run fine. Perhaps I should get a bottle of Techron (if it's available) and add it to the tank.

Oh, Techron is readily available. They'll have it in a good sized Wal Mart of almost any auto parts store. Toss it in every oil change or two. Your engine will thank you for it. Your Ion is going to set longevity records under any circumstances.

I was going to say that's too often, but then I remembered that I'm down to about one oil change a year, so that's just about right.

Yeah, a year or 10K miles (a synthetic oil change or 2 dinos) sounds about right.
#24 of 24 Does Saving Pennies on Gas Put Your Car's Engine at Risk?

"Mazor believes that the driving public has outdated notions about gas. Twenty years ago, only premium fuel had detergents in it. Back then, it was beneficial to occasionally buy a tank of high-test gas to clean the engine. Then, he says, "regulations were very lax and there was little enforcement. But all that has changed."
Likewise, Randy Stephens, chief engineer for Toyota's Avalon, isn't wholly convinced by the claims of engine protection afforded by higher-priced gas. He says fuel experts at his company study the effects of different brands of gas on the Toyota engines. Automotive engineers disassemble engines after 10,000 miles of running them on different brands of gas to see if there is a difference.
"Honestly, in the 10 years I've been in charge of Avalon, I've never seen one come back with any sort of deposit issue," Stephens says."
