Does anyone know if the oil life monitor will be accurate with synthetic oil in the 2.4's? I would think it's the same sensor as the one in the 2.0's. And they come with synthetic. Or is the sensor calibrated for dyno oil?

 

I dont think that the oil life monitor is accurate with any type of oil. I have 2500 miles on my SS 2.4 and my oil life mon. says I am at 68%.

 

Mina has been at zero ever since me second oil change. Enough said.

 

3800 km on mine and 66%. I don't trust the darn thing.

 

Did you remember to reset it?

 

The oil life monitor uses a set of calculations based of several measured variables such as engine temp, rpm, etc to determine a realistic oil life measurement. I really don't know why you guys don't trust it, it's fairly accurate and reliable.

If you think you need to change your oil every 3k miles (4800 kil) or 3 months then you've let yourself be duped by money hungry companies that tell you false values to get your $$$. Follow the DIC and change your oil when it gets down to the 10%~20% range and get your oil changed then. GM themselves in their documentation for vehicles with the oil life monitor suggests following the DIC or at least once a year, or cars without DIC 5000 miles or once a year.

Cars that DO NOT come with synthetic do not have their oil life monitor calibrated for long life synthetic oils. If you just use the 5k mile synth oils follow what the DIC suggests, but if you use the other ones just add the overage after you hit the normal change time.

 

mhmm weird:S did u reset it

 

So if I follow your advice, I would not have to change my oil until I have around 7500 miles. I do not think I will be trusting my oil life monitor.

 

its not uncommon for cars to have 7500 mile recommended oil change intervals for mostly highway driving. GM would be highly stupid, when people get millions for spilling their coffee, to put any type of device on their car that would recommend anything other than a very conservative estimate of when to change oil. first person that suffers oil related engine damage to DIC would have a class action going so fast, it wouldn't be worth it. the oil out of my balt has looked much better at 7800 miles (when DIC indicates its change time) than what used to come out of my cavy at 3500.

 

Thats entirely accurate! Otherwise GM wouldnt have put it in there because they would ultimately get screwed by warranty repairs and lawsuits.

Go by manufacturer specs, use the recommended oil, and change at around 10%.

If something goes wrong (and it wont) get it fixed under warranty.

The whole 3,000 Mile/3 Month thing was only used by oil companies to maximize profits.

 

You said it!
Thats also very true!

 

the only reason i don't trust the whole "if anything goes wrong just have it fixed under warranty" saying is because i owned a 1992 saturn sc2 where the previous owner probably did oil changes every 8k miles and the piston rings became frozen at about 58k miles...so by that time it't too late to have the warranty do anything. oil problems normally don't arise until later on in the motors life (such as high mileage) so i'm not willing to "trust" anyone when it comes to engine life

 

at about 7500 - 8000 miles I did my second oil change after doing my first at 3000 and wondering why it still looked damn near new ... after talking with the service department at my dealer they mentioned that the monitor is very damn near as accurate as any other method cept of course a lab test. GM would not risk putting the meter in there if it didnt work. The 3000 mile deal is **** to just get you in to make profit. Now saying that the service guy who I always go to mentioned that you should change it at or before 10% life left but recommended a change at around 25% life left if you wanna be picky. This is also a good way to gauge tire rotation under normal driving conditions.

 

I don't understand why people are still changing there oil at 5000 km, this DIC is not new technology, GM has been using it for over 10 years.

I know for sure it goes as far back as the 1991 Vette's.
plus anyone who's switched from regular oil to synthetic, have lengthened the oil change intervals for over a decade.

now if you start modding your car I probably would start changing it a little sooner then the oil life recommendation. but that will only apply to people who are modding internals.
just my 2 cents

 

i know on my moms new accord you're not supposed to change the oil till 10k miles... something about the break in period... that true for our chevys too?

 

I pick mine up tommorrow, so I don't have the owner's manual yet. Please tell me what DIC is short for, it's driving me nuts!

 

some cars get a special break in oil, which makes the engine break in period, less stress ful, but this is for engines which are not extensively broken before assembly, which is not necessary for our cars because all engines are run prior to shipment for assembly.

you'll find that more common on vehicals which don't use a Synthetic oil like Mobile 1.

I've been changing my oil to the monitor which tells me to change at about 10,000Km
(I do a lot of Highway driving), and each time i checked the oil and it's still good to go for longer. I have 30,000km (about 18,600miles)

 

I change mine every 7500 miles, and my my car is fine

 

i checikedmy oil at about 5,000 miles, and i'll be damned if it didn't look like new still... i'm at about 6300 now, and will be changing it soon

 

driver information center....

 

^^^ yea, you DIC head.

 

the guys from GM called me, the customer satisfaction thing, he said that for the first oil change, do it at 3000 miles and reset the monitor. then after that you can follow the oil life thing on your hid, he said with the ecotech you can run on synthetic oil for 4-6k miles

 

Thanks for the info.

 

my dealership said that the oil doesnt need to be changed until around 7500 miles because it is running synthetic. (which lasts longer than conventional oil)

 

Reset it.
Its very easy
