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.

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

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.

Thanks for the info, did not know that.

Have you seen any tech explanations on how it works?

AMSOIL Recomendation

--------------------------------------------------------------------------------

Extended Life 5W-30 Synthetic Motor Oil (XLF)
AMSOIL Extended Life Synthetic Motor Oils deliver exceptional protection for 7,500-mile/6-month oil change intervals or longer where stated by vehicle manufacturers or indicated by electronic oil life monitoring systems. They provide "Peace-of-Mind" for owners of modern vehicles where drain intervals exceed conventional oil recommendations of 3,000 miles.

AMSOIL Extended Life "XL" Synthetic Motor Oils exceed the current performance requirements for gasoline engines and deliver exceptional performance by controlling wear and maximizing fuel economy.
AMSOIL XL Synthetic Motor Oils are convenient and cost effective. They last longer than conventional petroleum motor oils, saving time and money. Motorists traveling 15,000 miles per year need only change AMSOIL XL motor oils twice, compared to five times for conventional 3,000-mile change intervals. While the initial fill may be more expensive than conventional oil, mile for mile AMSOIL XL costs less.

AMSOIL Extended Life Synthetic Motor Oils provide peace of mind. The oil drain interval recommendations for many of today's vehicles extend well beyond the traditional 3,000-mile interval, some up to 12,000 miles with electronic oil monitoring systems. And unlike petroleum oils that have 3,000-mile maximum recommendations, AMSOIL XL Oils provide 7,500-mile/six-month drain intervals or longer where stated by vehicle manufacturers or indicated by oil life monitoring systems. When using AMSOIL XL Synthetic Motor Oils, protection and performance are not sacrificed with longer drain intervals.

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

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?
