I changed the oil and filter on my 2007 LS2 last week, and I went in to reset the oil life meter and it only resets to 99%, what happened to 100% ?

Thank you,

Dave S

Be thankful for what you got....might have been 9%

Vette_DD

Maybe it figures you spilled that other 1%.

That happens when I reset mine as well. I've reset it after it showed 99% and I think it reset to 100%. Not positive on that however. 99% is close enough for me.

Not sure exactly which is which but I am pretty sure I read somewhere on this forum that having the car running or in accessory mode defines whether it sets at 99% or 100%. I could be off on the running or not part but it will reset at 100%. It probably says exactly how in the owners manual. Anyway, somebody here will know exactly what to do but fear not, there is nothing wrong and it will set to 100% if you choose to keep searching.

So following is the procedure from my 2013 manual:How to Reset the Engine Oil

Life System

Reset the system whenever the

engine oil is changed so that the

system can calculate the next

engine oil change. To reset the

system:

1. Press the TRIP button so the

OIL LIFE percentage is

displayed.

2. Press RESET and hold for

two seconds. OIL LIFE

REMAINING 100% will appear.

If the CHANGE ENGINE OIL

message comes back on when the

vehicle is started, the engine oil life

system has not reset. Repeat the

procedure.
Two possibilities here. maybe didn't press AND HOLD for two seconds or maybe you did the reset with the engine running (as previously stated) as the procedure mentions later about starting the vehicle. OR MAYBE THIS IS MUCH ADO ABOUT NOTHING! (or at least 1%)
Seems that the forum is suffering from some slow days recently.

Hay you might be on to something, My C5 always reset to 100% with the trip meter, but I tried it with the engine not running, I'll try it again with the engine running and see if that works ? Thank you,

It never resets to 100%

Never has and never will.

HBsurfer

Mine does.

J.Moore

So does mine. 05 Coupe with 79k miles. Changed oil & filter last week and reset with engine running. 100%.

Well i went out last night and tried with the engine running and still just 99%, I grateful it at least goes back to 99%

FatsWaller

Here's your workaround. Wait until the meter reads 98%, and reset it. If it goes back to 99%, then it's correct because you 'used' 1%. Because of the perversity of inanimate objects, it'll probably reset to 100% but you'd be no worse off than you are now. I'm guessing you're going to change the oil long before any of this matters.

BadAV

My LS2 only reset to 99%. I didn't care because I'm not THAT OCD.

hawkgfr

only 99%.







99.999999999% of all Corvette users change oil inside of 50% life anyhow...





(I never saw 100% on any of my six Corvettes...My Ridgeline though does show 100%

Crow Hunter

My 2006 has always read 99%. That's good enuff for me!

C6ToGo

Shop manual says to reset while ignition on and engine off:

Follow this procedure to reset the GM Oil Life System ™:

1. Turn the ignition to ON with the engine off.
2. Press the TRIP button so the OIL LIFE percentage is displayed.
3. Press the RESET and hold for two seconds. OIL LIFE REMAIN 100 percent will appear.

The Corvette and all my new vehicles always reset to 99%.

Crystal Dream

Following the procedure shown in the OM, mine resets to 99%, also. Just wait until your trip odometer resets itself after 2000 miles! That is a head-scratcher...

HBsurfer

I just used this procedure on my 2007 base today and it reads 100%

saplumr

Just tried that and sure as sh!!ten it did work. Moral of the story is read the owners manual. I’ve been ok with 99% for 16 years.
