I have 2019 Grand Sport with 1150 miles. I had the oil changed at 500 miles and the OLI was reset. Now after only 650 additional miles, it is showing an oil life of 60%. I checked the oil and it is showing full. Any ideas of what could be the problem?

 

How long has it been since you changed your oil? The OLI is also time dependent. 0 percent at one year even with no miles.

 

 

For 4 months 3 weeks, 60 percent sounds about right.

 

It's impossible to pinpoint without more information about your C7.....

The OL indicator will call for an oil change at 1-year. It has nothing to do with whether the oil has ever been used. That's GM, Engineering for you. LOL!

My C7's oil is almost 2.5 years old. Still NOT timed out. #LOL! More GM Brilliance at work!

 

I only have a 710 filler. ....

My Ferrari calls for an annual fluids change - ALL fluids change - even with zero miles. Belt changes and gaskets and such replaced every 30K miles or 5 years...... I just budget for it. I figure they know more about my Ferrari than I do. Ditto for Corvette engineers.... of course, I put about 25K year on my Corvette so five oil changes a year is the norm for me anyway......

 

I don't know how many times we need to tell you this before it'll sink in. Your dealer reset your OLM when you bought the car, (or someone else reset it at some point after you bought it) that's why it hasn't hit zero yet. It's IMPOSSIBLE for a C7's oil life meter to still be above zero if it was reset over a year ago. It will ALWAYS reach zero before or at the one year mark. You don't have a magic C7 that defies this logic.

 

 

Devidog, Yes the OLI will be less after sitting this winter..

 

 

The OLI takes a few factors into consideration, it's just that time is also one of them, so even if you reset the meter and don't drive a single mile, it will still count down to zero in one year. And so while your car is in winter storage it will drop down at a rate of about 8% per month. But in addition to time, it also takes into account your oil temperature and rpm, so if you drive it harder then it'll count down faster than someone who drives more gently. If the oil gets hotter than normal more often (as it would on a race track) it'll also count down faster.

 

Not at all .

The OLM doesn't test or measure the oil in any way; it is strictly an algorithm that takes many variables and metrics into consideration. Among other things, it measures mileage, time, trip length, driving style, etc...

 

" I noticed on my work order that 5 w 30 was krefilled instead of the new 0 w 40. Will that affect my OFI readings?" No.

 

For whatever reason you only drove 650 miles it 4 1/2 months your lucky it's not showing even lower! I'll explain:

My '88, '93, '08 Vettes all said in the Owner's Manual change oil at XXXX miles or for the 2008 that had an OLM, when it said OR 1 YEAR WHICHEVER OCCURES FIRST!

The C7 is the first Vette to use time as well as many other parameters to define when to change. With my C6 had to keep track myself. So regardless of miles each month it will reduce the time from 100% by 1/12 = 13%. Can see why GM included it as it appears many folks never read or followed the Owner's Manual!

SIDE BAR
Some "get their shorts in a knot" because the C7 tells you the time you should have read and followed with every Vette! Or worse. My '93 Vette stated this for oil changes in the Owner's Manual:

Change oil every 7500 miles OR ONE YEAR WHICHEVER OCCURS FIRST.
BUT if most drives are under 4 miles CHANGE OIL EVERY 3000 MILES OR 3 MONTHS WHICHEVER OCCURS FIRST!

It's not that the oil wears out in 3 months or necessarily even in 1 year, it's the combustion products that get past the cold pistons and rings at each cold start. The worse thing for an engine it NOT to have that oil get hot enough after a start to evaporate much of the water that is a key product of combustion. It combines with the sulfur and other "stuff" and forms sulfuric acid etc! That corrodes metal parts. If driving 2 or 3 miles to the store and back the oil never gets hot enough long enough to evaporate that water. Three months of mostly 2 and 3 miles trips (or even worse pulling the Vette out of the garage many time to get something behind and pulling right back in) than 7500 highway miles with few starts!

The OLM measures oil temp and time after a start. If you do only drive short distances it will say to change before a year! Better that the GM "guess" in 1993 of change every 3 months! It also uses engine revolution and other parameters but does NOT measure anything in the oil! It would not know if you (or a dealer) put in straight 40 weight oil.
