I get 2 free oil changes a year from by dealer. The person at the front desk assured me that I will get synthetic if that is what is required, which it is.

I got my oil change on Jan 20th. I drove for about 2k miles and the change oil warning came up.
I don't drive hard so how could synthetic oil get used up so quickly? Is the dealer putting the regular crap in and lying to me? Thoughts?

Regardless of whether they put standard oil or synthetic oil in, after only 2,000 miles it should not need to be changed, so either they didn't add enough at the oil change or your sensor is malfunctioning. Have you physically checked the dipstick to see if it's indeed low?

not yet, came up this AM. I guess I will try that
thank you

After the oil change, the system has to be reset so it knows the oil was changed. Turn key to on, depress pedal 3x fully to the floor and back in 10 seconds or less and turn key off.

Oh yeah I didn't even think of that. Most likely what happened. Good call sir!

it was reset. The oil change was 3 months ago, the warning only came up today

does the car know that the oil is dirty or it's just based on some time period?

Pretty sure the oil change notification is by odometer reading.

Some cars do it by drive cycle... aka number of miles

Other, usually more expensive, cars actually measure the "dirt" in the oil.

I believe these cars do it based on miles. It may also have a drive cycle and/or time component to it but IDK. The owners manual will probably tell you.

Either way, with full synthetic it should go at least 6k miles on the 392. I would just check the oil level and reset the light.

This is from the 2012 SRT owner's manual...

Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Have your vehicle
serviced as soon as possible, within the next 500 miles
(805 km).
NOTE:
• The oil change indicator message will not monitor the
time since the last oil change. Change your vehicle’s
oil if it has been six months since your last oil change,
even if the oil change indicator message is NOT
illuminated.
• Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
• Under no circumstances should oil change intervals
exceed 6,000 miles (10 000 km) or six months, whichever
comes first.

More from the manual...


Oil Change Due
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Due” message will
flash in the EVIC display for approximately 10 seconds
after a single chime has sounded to indicate the next
scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate dependent upon
your personal driving style.

I say check the oil and if it checks out, reset it and go from there. My car had an oil change light come on about 3 weeks after I changed the oil. It was my mistake for not resetting the light. :notallthere:

What car is measuring dirt?

Typically two methods, often a combo on some cars.

Miles
Drive profile, temps, revs, run time

Daimler discovered that oil degradation is correlated directly with its ability to conduct electric current. Therefore, Daimler has fitted V-6 and V-8 engines with a digital oil quality dielectric sensor, that is mounted above the oil pan along with an analog oil level sensor. This sensor measures changes in capacitance, which effectively is a proxy for the amount and type of contaminants and oil degradation products present in the oil. An increase in dielectric constant (less resistance to electrical flow) indicates oil contamination and degradation.

Daimler-Benz (Mercedes-Benz) has been incorporating the sensor into its vehicles since 1998.

Some Cadillacs and other high end cars have this as a resistance tool as well on board in the oil systems to monitor.

Our cars have an algorithm that is calculated based on miles, gallons of fuel, temperatures and sustained idle.

The only real way to find out what is going on is to do an oil analysis. This sampling detects all the potential problem areas before they become catastrophic!

Our customers go at least 10k miles on their oils or 2 years. Some as high as 18k miles on one change.

Even 2000 miles is too soon on dealership oil.

By the way, "synthetic" is not a characteristic but a function. There are very cheap quality synthetics that companies use. Ever since the Mobil vs. Castrol lawsuit, this word has become fuzzy and blurry!

Try QuantumBlue once you get rid of the free oil changes and see what a real designed oil feels like in the car!:beerchug:

I change my oil every 5k or 4 months and have never had the oil change light come on in over 40k miles driving on it.

Have you ever considered trying our lubricants and ACES IV? 4 months or 5k is very short. Our blends can double or triple your current interval and give you a better product. I see you have installed a lot of aftermarket products and seem to have missed us.

Just curious.

I might be interested... I don't race my car just a little spirited driving once in a while. Not sure how much I would be able to feel the difference. I would have to test my current Oil then test your oil at the same mileage. Too really see the difference.

This is why we make the Competition Formula QuantumBlue so that it is a street/strip lubricant that is made to protect during every day use but will protect you if and when you get hairy with it!

As far as a difference, our customers call me back after using the oils and ACES IV and can't get over how much of a difference they make. Throttle response, smoothness, fuel economy, quietness (Hemi Tick) etc.

I would have to test my current Oil then test your oil at the same mileage. Too really see the difference.

Yes, we would have to do that to make sure. However, you can get a good example by the 14,011, 16,600 and 18,230 mile samples in 5.7L Hemi Engines that have come before you! Jed's OCD has gone 167,004 miles on 13 oil changes so an average of 12846.46 miles per oil change. Based on the 5k miles you have been going, that is 2.57 times longer on an oil change each time. The analysis shows no wear!

Thanks for the dialogue! Hopefully we can talk about it on your next change!
