Oil Change Frequency

[adam1991]

You are probably right, think I'll start doing it every 1500 miles!

Every fillup.

You can never be too careful.

Actually, just run some lines and a big reservoir and dump tank, and have fresh oil going in with old oil going out while the engine is running.

Fill up the fresh oil reservoir, and empty the dump tank, when you get gas. Problem solved.

Total loss oil system like early motorcycles had! No dump tank, let it go straight on the ground!

That’s what CNC machines do. 10’s of thousands of hours on the ball screws and linear guide ways with minimal wear.

I was told with my Big Bend that I should be getting getting an oil change every 5K miles even though my percentage of oil life doesn’t indicate that.
how often do you get an oil change?

A little over 6k on my 2024 sas 2.3 and just did my 3rd oil change, and second air filter.

It has been 80% offroad since I bought it, in VERY dusty conditions.

To each their own, but i do my own service, so its not as costly as taking it in to the dealership.

Do you have proof of your statement? And possibly it's true, but I'll standby that changing oil at 3k miles is better on turbos than letting dirty oil lubricant those turbos with 7,8,9,10k miles on it!

Yes, standby. In the meantime, ponder how all turbocharged engines are the exact same and there's absolutely no room for improvement these past 120 years or whatever.

Okay, this literally made me laugh out loud.

It is true, though. Maybe not going from 40-40 to 20-20 true but...


Is it true that if you turn down the radio in your car you can see better?

AI says...

No, turning down the radio doesn't literally improve your eyesight, but it
does help you focus better on visual tasks, like driving or navigating unfamiliar areas.
Here's why:

Distraction Reduction: Music is a significant source of distraction while driving. By turning down the volume or turning it off, you reduce the auditory input that competes for your brain's attention.

Prioritizing Sensory Input: When you need to concentrate on a visual task, your brain prioritizes the visual information, effectively "turning down" the auditory input in the background to free up cognitive resources for processing what you see. This means you'll dedicate more of your brain's processing power to visual and spatial awareness, which are crucial for safe driving.

Cognitive Load: Driving is a complex task, and adding distractions like loud music increases the cognitive load on your brain. Reducing those distractions helps your brain allocate more resources to the most important task at hand.

I know at my age I don't process multiple simultaneous things as well as I did at 20 -40.

Not going to read thru 9 pages of 'you should do this' 'you should do that.'

General consensus anymore is 5k is a safe margin for modern engines. It used to be 3k.

You're also fine to go by the indicator light/oil life sensor, as long as you actually get it changed before it hits zero every time. Probably in your best interest to keep it documented or have it done at a dealer if you're going to do that, that way they already have the documentation if something happens - like a spun bearing or gouged cylinder wall from improper lubrication. In that case you'll be able to point at it and say 'I did things per your recommendations'. Not always the best defense but certainly can't hurt.

In 2005 I ran my 2003 Honda for 23,000 miles with Amsoil, which is rated at 25,000 miles. When I changed it, it poured out thick and light brown. I had a race engine building mechanical engineer inspect it. He was very impressed. I should have had it tested but did not. The true test was driving the same vehicle for another 18 years without a single mechanical failure and changing the oil once per year there after. I would still be driving it if the northern winters and salt had not destroyed the undercarriage. Do what you want though.

I change oil and filter every 5k and rotate the tires...

 

[B A C N O W]

I change my oil every 4k miles after the initial change at 1500 miles! I use only premium top rated full synthetic oil and i change it myself!
Oil is cheap and the task time is minimal while the actual service is simple! Why would you want to stretch that interval?

How many people are having engine failure due to changing their engine according to Ford recommendations? Nobody.

How many people are experiencing accelerated wear due to fuel dilution and have no clue it is happening while following Ford (or any other OEM DI engine) recommendations?

@CarbonSteel , going from memory but did you not test your factory fill which is the Motorcraft synthetic blend? I recall it had sheared out of grade with something like < 3K miles?? (going from memory).

It was out of grade in 1,000 miles (already a xW-20). Had I followed the iOLM, it would have been at the bottom of the xW-20 range or worse into the xW-16 range. I changed it at 1K miles and started using a 12.2cSt @100C oil that does stay in grade allowing me to run it to 5K or so.

Like most DI engines, I have fuel dilution despite not short tripping, in fact many of the miles are long highway trips where dilution should be the least and the ability for the fuel to evaporate is the greatest.

When folks say "I'm following Ford recommendations" in using Motorcraft blend (or some other oil) well after it has sheared/diluted itself out of recommendation, I have to wonder what the mean.

Here is the detailed engeering/scientific spec sheet that Ford uses to define its recommendation:

WSS-M2C961-A1

If I recall (going from memory) you may have purchased this document? In any case, I don't have it. However, I would be very surprised if it says something to the effect of

"the oil used must start out within these specifications, however if it shears/dilutes out of these specifications it is "ok" to continue to use this oil for 5,6,7k miles"

I would be like totally surprised, valley girl surprised

Yes, I did buy that specification, and you are correct--it states nothing about continuing to run an oil that has diluted/sheared past its intended viscosity.
