I drive my car hard. And I know the oil life is based on that. But my first oil change came at 2300 miles (oil life was at 5%). And 1000 of those miles was a road trip of pretty much all cruise control. I figured maybe first oil change is coded to go faster. I'm now at 1400 miles and my oil life is at 64%. Somehow longer even though most the miles now are city. But still on track to pretty much get 3000-3500 miles out of it. Not a huge deal. Oil changes are cheap. But is this normal?

Check your oil level every fill up for the first 2500-3000 miles. They lose some oil until the rings are fully seated and then not a drop after in my case. Not sure about the oil health algorithm but I never went by that.

The Oil Life value is affected by actual driving conditions. Your car knows how it's being driven and adjusts the Oil Life Value accordingly to protect the motor.

Yup I get it. But 2500-3000miles on OEM synthetic? Seems a bit excessive. Oh well better safe then sorry.

The only other indicator would be an actual Oil Analysis to see how much metal, fuel and combustion byproducts are in the oil. The Oil Change algorithm in the car is essentially a "timed" oil analysis, just with no real data like a real Oil Analysis.

Engine Heat consumes oil additives, so another factor for oil changes. The harder you run advances this clock.

During the shutdown, I didn't change mine for 9-10 months, 3200 miles, since the oil life thing wasn't at "0" yet.

Make sure you are following the manual requirements too(6 mon or 5K). The Oil Life monitor is "smart" but not does not seem to be timed at all. I've never had my oil life below like 45%, but I don't drive much so I hit the 6 month mark every time. When my warranty is up, I'll be switching to once a year most likely.

Short of on board sampling, no oil algorithm % left is entirley accurate. It's kind of crazy to think one needs to change brand new oil after 6 months of winter storage...especially a good synthetic. Has to be a CYA thing for Dodge.

Or a money making thing for the sevice departments...

That's a great idea. Probably gonna send a sample in and see how the oil is actually doing at the 2500-3500 miles rather then the computer. I did some research and it seems they changed something for 22 in the algorithm because alot of owners are reporting that. As well as people who owned an older year hellcat and now a 22 saying timing is about cut in half

 

[baabootoo]

Great idea, Pennzoil will love you for that!

Back before Hellcat they set the normal cars at 12 months and 10,000 miles and the SRT cars at 6 months and 6,000 miles knowing that they were performance cars and would likely be run harder and they've just stuck with the 6/6 to this day.

The oil algorithm is a little more than a 'timed' analysis. It has not just time, but starts, stops, timing, temp, engine loads and a bunch more...but is still essentially running a little blind without an onboard sampling system...which will likely never happen

Normal for you and your style of driving.

I had my 2018 Hellcat's oil changed every 5K miles (or every 6 months) and the oil life never got below 30%. The bulk of my driving consisted of a 60 mile per day work commute mostly on the freeway. Generally I drove the Helcat to work 2 days a week. The other 3 days a week I drove my MINI JCW. it also served as my city car for running errands.

Might add I gave a co-worker a ride to the train station. This required about 5 miles of city driving. By the time I reached the station the engine was fully up to operating temperature, with the oil temperature up in the 230F range. I frankly liked seeing this as I knew with the oil that hot, the engine that hot, water in the oil was turned to steam and being removed by the crankcase ventilation system. Keeping the water content of the oil down helps prolong the service life of the oil.

As an aside the Hellcat engine took "forever" to get even warm driving on the freeway. But after nearly 30 miles of freeway driving at some point both the coolant an oil termperatures were up to reasonable "warm" temperature.

Short trips with the engine failing to get to full operating temperature and remain there for a while really hammers oil life.
