5k,10k,15k synthetic oils

Not that I would ever go that long between oil changes, how do you guys feel about using the 10K or 15K oil to change every 5K mi?? The prices for the 5 quart are about $3 more than the regular synthetic. I change my oil every 2500 anyways but was looking to go to 5K. Would it be best to go ahead and get the longer wearing oil? If so, how about using the 15K oil every 10K??

 

I personally still don't like it. Yeah the oil viscocity might not break down, but you still get dirt in there. Even in my beater cars I wouldn't run it. I would rather take the 15 minutes to change the oil.

For the lazy man than this is the sh*t!!!!!!
