WTF is: TOP TIER Detergent Gasoline?

[Vance]

So in my preparation to get back on 2 soon I've been reading - A LOT - about how to ensure keeping engines running clean, etc, as best as possible with day to day type choices.

One thing I came across recently on a number of different sites as a suggestion was to be sure to run "TOP TIER Detergent Gasoline".

I remember with my Aprilia when I got it Dyno burned - the shop said to run 91 octane minimum. But - in reading on various sites and forums about stuff - they're not referring much to octane so much as this "TOP TIER Detergent Gasoline" stuff...

So my question is - since I'm guessing the CSC's own page on gas (http://www.cosportbikeclub.org/local/highoctane.html) is WOEFULLY outdated (are any of the pages not on the forums updated anymore???) and doesn't refer to such a thing but to high octanes... can someone in the know talk to this stuff, and equally importantly, where to find it, how much it costs compared to say normal 91 octane, benefits / drawbacks, etc, etc, etc.

"Top Tier" generally refers to name-brand gasolines, like Conoco, Shell, etc. Top Tier gasolines are suppose to have better detergent packages than the gas sold at mom-and-pop shops, grocery stores, and the like.

It's not about the octane level, it's about the detergent package.

Higher octane isn't always better - most times it is just pissing away money.

So... basically buy 91 octane at Shell or such and all is well?

Run the lowest octane you can get away with, w/o experiencing pre-det. It'll provide you with the best performance on a otherwise non-engine-modified sportbike.

I put 85 in Gemma and all the naturally aspirated vehicles I have, and none of them have ever had a problem with it. I do try to stay away from "off brand" stations, but they're few and far between anyway.

Higher octane fuels are intended for vehicles that are actually capable of taking advantage of it. TC/SC cars, etc. :up:

Try the non-ethanol unleaded at Pynergy and Brad's Conoco. Your bike will like it.

Basically, but the octane you need will depend on the bike. Usually the lowest octane you can run without engine knock is best.

I typically run 87 from Conoco in my R6, except when it's really hot out then it's 91.

My Ninja 500 runs on 85 and would probably run fine on piss after a night of serious drinking.

The main thing you want is quality fuel with a decent detergent package.

Roger that ---

Thanks everyone for the information! It actually makes a bit of sense now!

[~Barn~]

Remember Vance, that because of the altitude here, it basically replicates the same effect that higher octane fuel provides for people at or near sealevel.

Shell 91 ftw!

In order to meet TOP TIER Detergent Gasoline standards, a higher level of detergent is needed than what is required by the EPA. Also, TOP TIER was developed to give fuel marketers the opportunity to differentiate their product.
Why did the six automotive companies join together to develop TOP TIER?


All six corporations recognized the benefits to both the vehicle and the consumer. Also, joining together emphasized that low detergency is an issue of concern to several automotive companies.

Clean engines help provide optimal fuel economy and performance and reduced emissions. Also, use of TOP TIER Detergent Gasoline will help reduce deposit related concerns.
