Have you read the entire thread? You're missing the point my friend. If you have coolant in your oil, and you want your engine to last, you need to change the oil.

Pre-tell, what oil is supposed to last 30,000?

Oh I didnt think you guys were talking about changing your oil with coolant in it, thats just throwing away money dude..

About the oil that needs to be changed every 30K.. I forgot what brand it was but there is one out there.

Did you mean "Pray tell"?
Mobile 1 extended performance is suppposed to be good to 15k, possibly longer depending on some variables.
And Amsoil makes one that they say is good to 25k....

That's exactly what I was saying.

I haven't come across anything like it, and there's another problem with that type of oil besides the price. Even if it withstands break-down for a long time, contaminants still build up. (i.e. it gets dirty)

I change oil when it gets dirty (around 3000 miles) or less if the car sits a lot and I drive short distances.

You guys forget that oil might last up to 15k, but your filter needs to be changed as well. So if you dont want to end up with bad bearings and crap in the engine change both when you notice that oil is dirtier than it should be.

Also driving with bad head gaskets is practiacaly impossible because you will overheat extremely and damage everything in the engine. even a hair thin crack can cause overheating.

Besides if you run your engine on syntetic oil all its life
and chage it regulary the engine can last 300000 miles easily. (big engines such as v8, diesel 1000000)

My 5 liter cutlass started smocking at 250000 miles (1983) By the sludge build up in it I could tell that noone
ever used syntetic oils or changed oil regularly.

hey, I have seen some strange people not changing oil for 50000 miles! Also my friend had a Ford tempo that was previously had been owned by a woman and the main bearing on it failed at 60000 miles resulting in
a really loud knock. (WTF?) The engine was mint inside.
And I am not picking on ladies here. (things like that do happen...)

All you guys say is true, but common sense shall be the issue here.
