oil change monitor on '05 Chevy

just got an '05 Colorado and reading up on manual. Is the oil change monitor useful at all, or gimmickry? Anyone notice over time that it does anything much different than
common oil change intervals?

Very useful, not a gimmick.

Keeps you from wasting oil. Keeps you from having to replace the catalytic converter prematurely.
Be advised; you do need to use a motor oil that carries the GM approvals listed in your owners manual. If you use non-approved oil, changing every 1000 miles wouldn't be often enough to avoid problems.

There are elements in fresh motor oil that burn off in the early stages of its use, these elements are poisonous to catalytic converters. Changing your motor oil before it's necessary increases the frequency that this happens and contributes to shorter catalytic converter life.

Have you seen any tech explanations on how it works?

Yeah, ah, stay the hell away from that shit: some of it is not certified for engines and will decrease the life of an automobile's catalytic converter; it may also void any and all warranties.

Amsoil "recommends" that you buy their product because they want your money.

As do many other brands of motor oil.

"performance requirements for gasoline engines."
Are there any other people out there who (along with Steve) don't know the difference between an 'engine' and a 'catalytic converter?'

Yes, the oil may cost less, the damage that occurs however, probably will not.

The whole point of following the vehicle manufacturers approvals.

Show me one bottle with a label that actually states that.

These cut and pastes from the Amsoil web site really aren't necessary. Anyone looking for a good laugh can easily find their way there.
BTW Steve, you never answered my question a few days ago about the manner in which you've personally experienced cooler engine temperatures while using Amsoil.
Are ya ever gonna?

By "Preferred Customer" they mean "ignorant retard who is willing to pay twice as much for an inferior product."

It appears that the Amsoil selling scheme is based upon the "multi level marketing" scams that a large number of other worthless and/or dangerous products use. That may be why "Steve" has been spamming every automotive newsgroup in Usenet she or he can find: in the "minds" of these retards, more spam equals more money.

Since engines are designed to opperate at specific temperatures, I'd stay away from any lubricant that is (1) not certified by manufacturers and (2) claims "cooler engine temperatures."

I got almost 10000 miles on my first oil change. 17K on it now, and have over 50% left.
