Oil your using? Duration you use?

Reading GM's manual for the car, it appears 5W30 API approved oil is recommended. What brands are you using? Motul? Mobil 1? etc....What duration are you changing it?

PLEASE DON'T tell me you follow the dummy oil change light.

The search function has more than enough oil thread results for you to research off of.

I use the supertech 20w 50 and I just change it when my light tells me to.

lol...ok not really

I have only changed my oil once since I got the car and I used penzoil ultra 5W20 and have gone about 4k miles on it so far. Ill probly change it at around 8k or so. Not to say you should base your decisions off of anything I do though. I dont claim to be an oil god by any means.

Why did you adjust your duration? Curious.....

I adjusted my specs on the previous car to 5w30 from 0w20 and duration to 5K miles +

I have been seeing where good synthetic oils are lasting 7-10k between changes. Plus our engines hold right at 9 quarts and I would assume the more oil the longer it takes for it to be broken down. 8 just seems like a safe place to change it out.

Pennzoil 5w30 conventional, i change the oil whenever the OLM says "service oil", which can be anywhere from 7k-10k miles in my case, once i get the cam i'm thinking to get, i'll switch to GC 0w30(syn oil), much better oil pressure from 6000rpm and up, which the bearings always love.
There, change the oil whenever the dummy oil light says so , really, or whenever you like to change it., either way.

Have used Mobil1 5w30 Dexos-approved, changed when the dash tells me. But I will be changing to Quaker State Ultimate Durability 5w30 next time. Why? There is a site you can find by searching "Bobistheoilguy" that has a ton of information that leads me to believe that the QS is at least equal to the Mobil1 and it is also Dexos approved. Oh, and it is $6 cheaper than Mobil1 per 5 quart container at Wal-Mart.

Major waste with such a good oil, especially with double the oil capacity that most cars have.

I change my oil twice a year, which comes out to around 7-10k.

Going to be trading in my G8 in January or February, 2013. It's been a good run. Thanks all. See you in the for-sale section soon as I pawn off some parts...

penzoil platinum 5w30. I usually change it when the OLM is around 50% which is usually around 5K miles.

Mobil 1 0W-30

I wait until the Oil Life Meter gets to under 10-2% remaining.

Once I use up the Mobil1 I have left, I'll use either the Castrol Edge or the Fram Full Synthetic I got. I'm not too picky/choosy about oil.

Hold down the left steering wheel scroll bar (enter key function) when cranking. Instead of the usual DIC LCD screen that you're used to, you will find "Engineering mode".

Use the same scroll wheel up and down to cycle through the extended information that it supplies. Throttle Position Percentage is a fun one! But Engine Oil Life in % is there in one of those options. Don't trust the battery percentage one, people have found it to vary widely.

If you press the road button on the steering wheel, you exit out of engineering mode, and can't get back in until another ignition-start cycle with the enter key pressed.

Hope this helps.

Hold down the scroll wheel with thumb while using other hand to crank with key.
