The 87 Octane You Buy May Be 91!

I work in a refinery (XOM) and we often ship 91 as 87 and 89 because we always try to make the highest grade all the time. So, we usually have so much 91 octane we can sell it as any grade. We can't however sell a lower grade as a higher grade of course. I always buy 91 (ten % discount

), but with prices this high i'm gamblinging on the 87! I know the manual recommends 91 but I hear and read it can handle 87 even at sea level with minimal notice.

That's pretty cool. Sometimes its the other way if you have an unscrupulous dealer. We had a big scandal of that going on in NY/NJ a while back. People were selling 87 as 93 and pocketing the difference.

I have only ever ran 87 in mine and havn't had a problem. And FL is pretty much sea level.

The manual recommends 87.

Yeah. Why does everyone keep saying you need higher octane?

Everyone confuses octane and some other rating. Recommended octane for the Titan is 87. The other number is 91 for some other measurement. If I knew more about the differences I would be able to remember the name of the other measurement.

Oh yeah, your right, kinda. The manual recommends you use AT LEAST an octane rating of 87 (AKI). You just might get 91 is all I'm saying.

Same thing happens a lot in most industries nowadays....when I was working for Intel, About 80% to 85% of the CPU's passed at the highest Mhz for the stepping of the CPU ( In this case it was northwood stepping P4 HT CPU's ) ....so 80% to 85% of them would pass perfectly at 3.2Ghz....but Intel charged an arm and a leg for that CPU at that time, so most of them got binned out to 3Ghz...2.8Ghz...2.4Ghz...etc Because those were WAY cheaper and Intel could sell them by the hundreds of thousands. So in actuality you were paying for regular unleaded ( 2.4Ghz ) and really getting supreme unleaded ( 3.2Ghz ) ....Intel was smart enough that they lasered a fusable link limiting the multiplier on those chips before packaging the die into what you see as the final CPU. Motherboard manufacturers caught on quickly to the scheme and adjustable bus speeds with the ability to lock the AGP/PCI clocks to 66/33 Mhz let Overclocking become the multi billion dollar business it is today. Even the 15% to 20% of the CPU's that were sent out that WOULDN'T do 3.2Mhz at standard voltages, MB manufacturers got smart on that too by giving us adjustable voltages to up the noise ceiling on the CPU to even let the slum CPU's run at " Supreme" speeds.

Like SRVNT said, It's easier to make the best you can and bin out the product as you see fit for the business....then to have 3 or more special lines producing 3 ( Or more in the case of CPU's ) different products.
