Safe to go to 15K Oil Change Intervals with M1 Extended Performance?
Synthetic Blend Oil every 3K - Where I started and went to...
Mobil 1 every 3K - did that for half a year and went to...
Mobil 1 every 6K W/Filter change / oil topoff every 3K - No problems so far so I decided to try...
Mobil 1 Extended Performance every 15K W/K&N Filter - Havn't started yet, not planning on changing filter before 15K mile either... Does this sound like a good idea? Definately can save me money.

I grabbed this from my stickey.

Thanx for the heads up. Some interestion material in here!

Basically, it's ok to NOT change your synthetic oil every 3k miles, btu DO change the FILTER every 3k miles. They ran the test to 15k some-odd miles and changed the filter every 3k miles or so.

I think this has come up on the LSx tech before but there seems to be alot of new members posting here and those who havent seen this will be just as surprised as I was.
All tests have been done on a stock 2002 LS1 powered Camaro Z28
Mobil 1 study: http://neptune.spacebears.com/cars/s.../oil-life.html
Amsoil study: http://neptune.spacebears.com/cars/stories/amsoil.html
Honepage: http://neptune.spacebears.com/index.html
This oil analysis study of major synthetic oil brands shows conclusively that it is better for an engine to leave synthetic oils (at least Mobil 1 and Amsoil) in the engine for at least 6-9k miles while periodically topping-off the oil and changing the filter around 4-5k miles.
This would also be a great thing to add to the sticky about engine specs. It will save people alot of money anually.

Wait, how do you change the filter, but not the Oil??? Do you pour the oil back in? Seems quite retarded to do that, why not just change them both at the same time around 7-8k or even every 10k miles? You would save even more money that way right?
If a filter only lasts about 3000miles, then what good is it? Shouldn't we have advanced filters that can last as long as our oil? Perhaps somethign a bit bigger would do I guess if it can hold more dirt/grime/generalcrap you don't want in there.
I think a test of this type should be redone, but to test the filter, not the oil.

The contaminants about doubled at 3k miles, they changed the filter at 12k miles and the contaminants went back down, go figure. Scroll down in the llink to see graphs.

As by the definition of a filter:
any substance, as cloth, paper, porous porcelain, or a layer of charcoal or sand, through which liquid or gas is passed to remove suspended impurities or to recover solids.

you DO KNOW that the oil doesn't drain out when you pull the filter...only what was in the filter and directly over it...basically about 1qt...
hence the "top off" step

Exactly, I change mine every 6k and the filter every 3k. Don't be cheap. I use Royal Purple In my silverado. It is in the every gearbox except the trans. I cant believe how much quieter my truck got after putting it in.

I hear that lucas oil stabilizer was no good, infact your oil is better off WITHOUT it than WITH it... CHANGE ASAP...and NEVER add that crap - it causes your oil to foam up under high RPMS...
So far I've gone 7K miles on M1 Extended perfomance without any problems, although it burned a quart of oil off - however my motor isn't any louder than normal nor is there any unusual sounds and the performance is still up to par...
