I have a 2017 Fit LX manual. When we first got the car, we needed to change the oil at 3k miles (the Oil Life Meter was at 15%). I wasn't that concerned since a lot of the mileage was my wife learning how to drive.

But the second oil change lasted only 3k miles as well before the Oil Life Meter hit 15%. I expected the oil to last much longer as a lot of the mileage was highway.

In both cases, we used the stock non-synthetic Honda engine oil (Castro?).

Having switched over to Mobil One, Im hoping some improvement with the engine oil life.

Im curious if anyone is having this kind of experience?

 

If you are changing your oil based on the Maintenance Minder, then I think it does not know what type of Oil you are using. There is no way it knows whether you put in Castrol, Mobile or Honda OEM.

So I would think changing to Mobil will not change the amount of time the maintenance minder gives you as it count down engine oil life.

I believe the maintenance minder uses different criteria for determining it's rate of oil degradation. And I think it's more connected to style of driving, as well as mileage.

I also believe OEM Honda Oil IS either full synthetic or synthetic blend.

3000 K, seems pretty fast between Oil Changes, I average in the neighborhood of 7000 miles between changes.

I would bring up my concern with the dealership service department. But unfortunately, I don't think changing brands of Oil should change your parameters of maintenance minder rate of deterioration.

 

I agree that the oil sensor does not know which brand Im using but the degradation should be slower with the synthetic. Im curious to see what parameters and measure the sensor uses.

According to the dealer, he said the oil that they use in his service shop is not a synthetic and suggested that I change my oil every 5k miles. Synthetic, he said, needs to be changed once a year. But at 3k miles for every non-sythentic oil, I suspect something might be wrong.

 

What kind of driving are you doing? If it's mostly city with lots of stop and go, the OCI will be shorter than if you're doing mostly highway.

I do mostly highway and I'm getting nearly 10k OCI intervals using 0w20 full synthetic.

When you saying burning oil, is the oil level low?

 

There is no sensor for oil degradation. The maintenance minder is only based on vehicle usage. Primarily it is just a sensor for engine revolutions. Driving it at higher rpm's will have it calculate shorter oil change intervals.

It also doesn't know if you're in dusty conditions vs clean air.

 

Nothing to do with the Maintenance Minder or the frequency of oil changes, BUT - Why oh why would you be using non-synthetic oil in the two oil changes? The manual clearly states synthetic and the grade specified 0w20 is only available in synthetic.

 

Both are good points!

 

80% city/20% highway.

If I was a smarter man, I would have checked the oil level before my wife took it took the shop before her 2nd oil change. Im assuming tho, that the OCI is telling me both the oil quality and quantity are running low.

 

The first oil change was free .... and with it came the blended oil. And the car came from the factory with blended oil.

After that, I made sure my wife put in Mobil One.

We'll see if the oil change minder comes on early with the synthetic oil.

 

The MM is NOT able to tell oil quality or quantity. It is not looking at the oil in any way, shape, or form. It uses an algorithm based on vehicle usage to determine the oil change intervals.

 

 

Is this a Honda Dealership? Because I believe the correct weight, Honda OEM Oil is only Synthetic or Synthetic Blend.
I have a hard time believing a Honda Dealership would use non-synthetic Oil in their shop.
As far as I know, most all new cars today have synthetic oil blend or full synthetic recommendations. If I was going to a dealership that didn't even carry synthetic, I'd change dealerships.

And yes, synthetic oil is more stable and doesn't break down as fast. But again, the maintenance minder doesn't know that. I would guess the criteria and parameters it is using to evaluate "Oil Life Remaining" IS based on the deterioration rate of the oil that IS recommended. Which is a synthetic.

Therefore unless driving parameters change, I wouldn't expect changing to Mobil would change the maintenance minders rate.

However, I agree that only 3000 miles seems incredibly fast. You might mention it to the dealership. You're still under warranty and there might be something wrong with the maintenance minder.

I'd be curious if this post finds anyone else who has ever experienced a deterioration rate as fast.

I would say my driving is average, leaning towards the conservative, and I at least, the very least get double that.

 

excellent question.

 

interesting indeed..

 

I like your modification and it explains why my MM tells me to change the oil every 500 miles and do a dance while it drains. Darn MM!

 

lol'ed mine too..!

 

stick with premium oil. me personally i run amsoil.they guaranty their oil up to 25k miles and is the best out there for di/forced induction engines.
its definitely worth the extra few dollars.my car runs ultra smooth and i have a mt car.the oil the dealership uses is very similar to mobil1 oils.
the reason you see top drivers and high horsepower cars promote mobil and other brands similar is because those dudes change their oil after
every run.reason being is that the oil can only keep up due to the fact that is burns up. heres an example back in 06 i ran redline in my evo ix
and changed my oil after 3k.all the other evo guys were running mobil1 full syn and they changed theirs after every 1k. to me thats redic!
just look up the noack oil chart and youll be good hop this helps
