What octane is everybody using

[BLUEKNIGHT911]

IT'S BECAUSE

Cheap fuel? It's a personal choice.

Something to think about.

The gasoline that is sold at your local gas station must conform to an EPA-mandated minimum level of “detergents” to help prevent and reduce the build-up of fuel related carbon deposits that both increase exhaust emissions and reduce engine performance.

Unfortunately, all the various blends and brands of gasoline are not created equal, plus some low-quality gasoline brands have additive packages that are not strong enough to keep the engine deposits under control.

Several of the world’s top automakers worked together to establish a higher “Top Tier” standard for gasoline that would contain a higher level of deposit control additives. Many gasoline retailers sell gasoline with a lower quality additive package, so unless you are always using a gasoline that conforms to “Top Tier” gasoline standards, it would be a good idea to use a fuel system cleaning chemical on a standard maintenance schedule.

Having seen several Spyder engines in various states of disassembly. All of them shared one thing in common. Lots of carbon build up....some were very low mileage motors too.

fwiw

....They are all set up to run overly RICH and there isn't anything you can do about it.........Mikeguyver :thumbup:

With running the risk of ticking some people off...
You pay $20 to $30k for a vehicle and consider using something other than what the manufacturer (engineers) recommend? :banghead:

There are reasons why fuel octane ranges are recommended -- however, having said that, I'll bet a case of beer there will be someone post on this thread with a long list of reasons why they know best and use whatever they want in their Spyder, and that it is better than the manufacturer recommends. :roflblack: Just another reason I do not buy used vehicles.

Most people do not even understand what octane ratings mean. Some believe the higher the octane the better the fuel; which cannot be any further from the truth.

Octane has nothing to do with the quality of the fuel; as so many uninformed seem to believe. If it did then everyone would use "rocket-fuel" in their vehicles.

In the most of layman's terms, octane relates to the "burn-rate" of the fuel; and various engines require specific burn-rates to work properly as designed to get the most from the engine and prevent damage over the long-term.

Use what the manual says to use... there is a reason they provide the suggestion.

Again... another reason I do not buy used vehicles.

Sorry if this ticks anyone off or offends them...

Illinois Boy, they will not believe you. instead they would rather save $1. per fill up which equates to less than $50 per year.

the problem with putting in a lower octane is heat. the fuel needs to burn almost completely and help to cool the valves. when you use a lower octane the fuel not only burns completely but, you also get small explosions in the cylinder which leads to burnt valves, scored rings and coking.

:agree: On a five-gallon refuel; it MIGHT be $2.00 more for me...
Money that I consider to be well-spent! :thumbup:

I also believe that using premium produces higher mpg's. :thumbup: I'm guessing 2 mpg better. :hun: Can I prove it? No. And don't anybody start with all the math solving this or that. ray: I don't need a headache. :lecturef_smilie: Tom :trike:

 

[Bob Denman]

I managed to document a 2.5 mpg improvement with 93 octane, versus 87; in my 2010 998. :thumbup:

Bottom line for me--I always put in the highest octane available when I refuel the :ani29:'s. I do notice a performance difference if I am forced to use 87--which is the lowest I have found here in Alaska.

I have 4000 miles on my 2014 RT and have always filled with 87 octane. Never had a reason to switch. I'm averaging 36 mpg and have never had an issue. Runs great! I run my 2011 RT on the same with no issues.
