So the computer monitors engine conditions and calc's oil life. Wondering what kind of numbers folks are getting before the 'puter notifies them.

I'm "on track" for about 7500 mi's...

2007 coupe 15K. I've been changing annually @ 3K & 50% +/- a little, just about all in town cruising. In late June drove 3440 miles, all interstate, 105F in AR,OK,TX, 70-90 mph. Left ABQ on fresh Mobil-1 @ 96% returned at 85%. Depends on service cycle. Dipstick didn't move. Eyeball extrapolating, I could drive 35K miles on an oil change exclusively at interstate speeds. Used 120.4 gals = 28.6mpg on the trip.

As per Blackstone's recommendation I will change mine between 5 & 6K. Later! Frank

Went on a trip last summer. Changed the oil before I left and when I got back. 5% oil life left, 10,360 miles.

Never changed before 3%, but was ~200 miles after 0% once.

I drive the C6 about 2,000 miles/yr. I change oil every 4,000 miles or 12 months, whichever comes first.

So, 2,000 miles per oil change. I need to take the car out more.

Pitbull11

have you ever done a oil analysis to see how the oil looked after these intervals?

Hell yeah. Get your moneys worth

I have driven 6K miles since my last oil change in December. I still have 47% oil life remaining. l normally change it at 50% oil life remaining, but I have been busy.

BigJoe

I change oil at one year or 7500 miles. Usually that is at about 20% left on the meter. Although my car is a daily driver/commuter car my commute is only 20 miles round trip so I don't rack up too many miles in a year.

TLS_Addict

2,500-3,000 miles in all my performance cars because they all see some drag strip time, not a lot and they are not highly midified so I feel that is a good number. The oil still "looks" good but that doesnt say anything.

Mixed driving and mostly cruising, my MPGs are always 24+.

Boozman

I've got 7,500 and still at 45% but I'm coming up on 1 year so I'll be changing it soon

peter pan

I change at 50% DIC not mileage

Vette_DD

No, not exactly.

I only put about 8K miles a year on my C6, so I change it once a year.

eboggs_jkvl

7500-8000. City driving with occasional long trips on the highway. Just got back from a 1700 mile run up and back to Ohio.

All highway and I'd hit 10K easy. City driving is a bummer.

Use Mobil 1 extended service and changed the oil every 3000 miles

GOLD72

The 06Z06 would make 7500, the '10 CTS Wagon at 10,000. The 07 Vert would make 11,000 miles but the one year time limit forces an earlier change.

I thought my 2011ZR1 would make 7500. But now well after my first change, it appears I will only make it past 6500 somewhat. I did an early first change at 5000.

LTC Z06

I use the best Amsoil and change once a year, and I checked their claims with a blackstone labs test.
