So the truck Penske gave me apparently needed to have an oil change, but the person in Oregon dismissed the warning without getting it done. So now it urgently needs an oil change immediately as it's 1.5k miles overdue. I am very annoyed because they knew I was driving way the hell across the country so wtf?

I am trying to not get upset and just frame it as extra time to do some laundry because I am running low on clean socks so why not.

Keep your fingers crossed for me that it all works out ok! I know it always does, but the suspense kills me 😅

Drain the oil buy new oil and replace.

Just watch out for the Americans, they smell the oil from 5 miles away and may attack 😉

How do you know it needs to be changed immediately? Did you look at the oil levels in the engine after the car has cooled off? I have driven 5k miles after the oil change light came on. Sometimes those recommendations are not the most optimal but the one that protects the manufacturer from liability.

Bro change your oil every 5k miles 😂 skipping or delaying oil changes is the number one reason engine components fail prematurely.

Oil changes are literally the easiest and most important maintenance task on an ICE vehicle.

The 5k mile recommendation, from what I understand, is outdated. They’ve been telling you to change your oil around that number for a long time. But cars have become more efficient since then and so it would make sense that the recommendation would also change. And if the oil levels are still good and the color looks normal, why not continue driving on a rental?

No, it’s not. One of my best friends is a professional mechanic and he stresses oil changes over everything. I have heard the exact same thing from diesel specialists that I’ve paid to work on my vehicles.

Engine oil is the buffer between all of the moving components in your motor. As the move (thousands of times per minute) they all rub. When metals rub they shave microscopic pieces off of each. Your oil becomes filled with huge amounts of hard and abrasive materials. The oil also gets degraded from micro plastics (gaskets degrading) and hydrocarbons (ICE by products).

No amount of efficiency upgrades stop or mitigate these processes.

I’ve heard the opposite from the same professionals. I also think it’s important to consider incentives.

The recommendation used to be 3k, so why did it change? If it’s something that is set in stone and efficiency or oil quality can’t change it, then it should still be 3k. That’s almost double efficiency per oil change.

What’s changed is the oil not the physical realties of engine wear. But there are many different mileage specs for oil change intervals.

The more often you change your oil, the less amount of miles driven with your engine’s lubricant filled with shrapnel and the less shrapnel per oz it contains.

You can delude yourself all you like but the facts remain. Oil quality and quantity degrades the longer it stays in the motor. Since oil changes are cheap and easy, there’s no good reason not to do them every 5k miles.

I have a 12 year old diesel vehicle and the manufacturer recommends oil changes every 10k but the dealership and a diesel specialist have told me to change it every 5k miles. Explicitly told that almost all of the problems they see in my model are due to the 10k mile oil change recommendation and downstream wear and tear from that specifically.

Calling me delusional isn’t necessary but seems like you’ve already made up your mind so no further discussion is going to be useful. Have a good day sir.

Agreed. It’s also the cheapest and most cost effective maintenance you can do on a vehicle. Just do it.

It's not my car, it's not even a car it's a 16 ft rental truck that's been working hard for me through desert and mountains for a week now. It didn't give me a warning that oil was needed soon (that happened before I got it) instead it started flashing it needed oil immediately. It turned out to be 2k miles past due already (that's how far I had gone).

I had to go into their truck depot which was an annoying detour but it's all fixed now. They were super nice and it wasn't so bad really. But it was totally their fault, the place I picked up the truck had cleared the warning without replacing the oil.
