diitto

Hi... Forgive me as I imagine this has been asked a thousand times but I did a search and didn't find lots of information (??)...

I have a 2012 GS Convertible that I bought new last April. I chose to have the first oil change done early, at about 2000 miles. Now I have 6000 miles and the oil life indicator (which was reset at the oil change) is still showing 50 % oil life remaining... Assuming it's linear that would say change it at 8000 miles on the oil (10,000 on the car)...

What's the consensus??? Do you follow the oil life indicator??? Or change oil more often???

Again, sorry if this topic is already talked about at length elsewhere... Send me a link if such is the case...

I appreciate the help... thanks... bob...

Just do as the manual says: annually or when the monitor says to, whichever comes first.

I like to change mine the first time between 500 and 1,000 miles, then at somewhere between 50 and 60% on the DIC.

I also did mine relatively early (3K miles). And do it every year or 5K miles, whichever occurs first. I'd leave it longer if only highway miles, but city miles can deplete some of the additive package earlier than the DIC IMO (which is only an algorithm, not an actual oil sensor, like some think). It's not a DD, so I do it every 5K max. Yes, we're probably being overly cautious, but I'm okay with that. Cost me the same to change the oil more often than doing lab analysis, and I enjoy doing it. Plus I recycle it, so not harming anybody or anything . Good luck.

I only put about 6K to 8K miles a year on my Vettes, so I change oil at about 10% or once a year, whichever comes first.

Change mine every 5K miles regardless what the DIC indicates.

I must be old school. I go by miles.

I will do mine every 5k or 6 months...

I follow the DIC and never change until it's 3% or less. GM spent countless hours, dollars, and hundreds of thousands of miles on the testing and research to develop a system that got the most and safest reliable amount of use from the oil in the engines in our cars. They certainly wouldn't give a 100K mile warranty if they didn't have extreme confidence the system worked as designed.

I change it once a year or when the DIC tells me to or after any HPDE.

I change mine every 1000 miles or when the DIC gets down to 95% whichever comes first.

Just kidding, always makes me chuckle to see people sticking to the old ways. Waste of oil and money. I do it when the DIC indicator gets down to 0%, typically works out to around 8,000 miles.

My wife's Merc C300 says to change every 10,000 miles, just changed it yesterday. And since the filter is on top of the engine, I suck the oil out of the dipstick tube using an oil extractor. Pretty simple and easy. Wish the Vette had the filter up on top.

I look for a 5 or a 0 or every 5k....usually turns out to be about 50 of dic

Your info is correct. M1 good for 12K of normal driving.

Flame Red

I do it once a year unless the DIC indicates to change it first.

SUB VETTE

Usually it's once a year.

I just change it when the DIC tells me to. DIC accounts for the higher oil temps and rpms seen during an HPDE.

I drive 3,000 miles a year and change oil and filter once a year per the manual. It's usually at 52%. I never need to add oil. Mobil 1 5w-30.

EyeMaster

Once a year if less than 20 000 km per year. Top up when needed, change filter at 10 000km if you want.

More than that is not needed.

I agree with this, but doubt I would ever see mine get to 3% in a year or less since I couldn't imagine putting 6-8k miles on my car in a year. I think that GMs logarithm on the oil change DIC indicator is probably set very moderately meaning the oil would probably be ok beyond the change oil now or 0% remaining. As some have said, Mercedes says do it at 12K. In my C5 which was closer to a DD in Europe, I changed at about 40% since we often drove long distances at high autobahn/autostrada speeds.
