I've got an '06 GTO programmed with the U7191. This is the first car I've owned that had the oil life monitor on it (you know, the one that tells you when it's time to change the oil based on mileage, engine revolutions, time of day, and lord knows what else...)

Anyway, does programming the ECM affect this calculation? I change the program between the Diablo tune and the 91 octane tune based on what fuel I can find when I fill up (93 is tough to come by in west Texas). I know the Predator doesn't display oil life in any of the menus, I've looked, but I wonder if the parameter gets reset when a new program is written.

I ask because it's been almost 7500 miles since I last reset the monitor, just testing it out to see how long it 'recommends' to go before changing the oil.

Any ideas?

P.s. When is TCM support due?

no, it does not affect the oil life monitor... (I have it on my car as well)....

the oil life monitor is affected by how hard you drive your car...

depending on how you drive your car, it is entirely possible for it to go for a year until it says you need an oil change...

fwiw, mine I usually change my oil at about 6000-6500 miles, and I still have about 30-35% on my oil life monitor...

I still change mine at 3000... Old habits and is cheap enough that I figure it could not hurt.

I know at 6000-6500 miles, my Mobil-1 oil still looks fresh... so I'm good...

cheap son of a

"looks fresh" and retaining the original viscosity are two different things sweetie


have you performaed a viscos test on that used oil after 6000 miles yet? better safe than sorry. especially in your high horsepower application.

yup, performed the test myself.. made my fingers all slippery.. good to go!

hey, if GM says to use normal/regular oil and to go by the OLM, and they haven't had any engine damage due to oil issues by waiting until that OLM tells you to change it, then I'm SURE it's aaaaallllll good using Mobil 1 full synthetic and changing at 30%, which is well before it would tell me to change it...
