Moble 1 - 15K mile oil

I would never use it either. Just because the oil is supposed to be better, your engine oil is still going to break down with heat and still have metal shavings. That is the reason why we change our oil in the first place right?

I suppose the new stuff is more heat resistent. I believe the theory goes that the filter traps particles large enough to do damage - everything smaller just keeps circulating but does no real harm...
I've always noticed that true synthetic gets dark real fast - normally, for dino oil, a sign that it is breaking down....

The occasional tiny particles worn away from normal use is typically trapped in the paper oil filter element. Why replace your oil if there's no need to. Do an oil analysis test and see how well it holds up. If you go 5K on oil and you get back some stellar oil analysis results, they may tell you that you can easily go another 3K, 5K, or more between oil change intervals. I wouldnt just blindly believe mobil that you can go for 15K without thinking about it, but I also wouldnt be surprised if this is a much better engineered oil than normal mobil1, and its safe to run longer than some other oils out there.

The main reason oil is changed is because it either is no longer staying in it's grade, or more often, the total amount contaminates has exceeded the oil's detergents and chemical capacity to suspend/neutralize them.
An oil's function is to lubricate, clean, and cool the engine. Additives are added to the oil to enhance those functions. If the oil becomes too acidic, it will corrode the engine.
That's why all the oil gurus' talk about the mysterious TBN number when they are measuring the lifespan of an engine oil.
In short, a TBN (total base number) measures the amount of active additive left in a sample of oil. The TBN is useful for people who want to extend their oil usage far beyond the normal range.
By comparing the TBN of a used oil to the TBN of the same oil in virgin condition, the user can determine how much reserve additive the oil has left to neutralize acids. The lower the TBN reading, the less active additive the oil has left.
However, the TBN is not the only factor to consider when determining how long an oil can be used. If wear accumulations and insolubles in the oil build up and become abrasive, it's recommended to chang out the oil, no matter how high the TBN reading.

i dont intend to go 15k on an oil change no matter what kind of oil but when you look at it versus regular mobil 1 the price difference is about $5-6 for 6 quarts and its simply a better oil than regular m1 so whats $5 more if its better for your engine?
I bought the 15k mobil 1 in the 5 quart jug at walmart for $24 as opposed to $20 for the oil M1 and got 1 quart individually since 5 is not enough for alittle over $5. $29 for oil is not bad when you think about how long it will last I'm not talking 15000 i'm talking 5-8000 when you consider how long it takes to drive that many miles its very reasonably priced.
as for using synthetic oils to help lower gas prices I don't think that if everyone quit using dino oils altogether and the oil companies quit making anything other than synthetic gas prices probably still wouldn't fall.

While speaking about oil.How was light sweet crude named
by taste or when the oil guys saw the profits they said
sweet.

sweet crude = low or no sulfur content.
sour crude = higher sulfur content

he said that GM wouldn't warantee anything over the 7000 mile one. GM's not
buying into that extreme oil changes>7000miles.

No matter what the mileage interval an oil claims to have, I wouldn't go longer than a 1 year interval at the very longest. As is, I pretty much stick to a 6 month/6k mile interval... and for me, 6 months always comes first. I basically change the oil once before racing season, and once after.

i hardly get 6k miles on my car in a year, lol. Let alone 15. But a problem that youd run into with the LS1 is, at 15k miles, there would be no oil left in the pan with the way these motors go through the stuff. Hell I find about 6oz of oil in my catch can every 3k miles, and im sure its not catching it all either. That would be my main concern.
