The 15,000 Mile OCI

[Cujet]

Going beyond 8000 miles in my vehicles results in poor UOA results. It also results in cam phaser "knocking". So, I simply don't do it anymore.

Just a note: GM reduced the OCI in many vehicles due to cam and balancer chain wear. It seems the longer oil change intervals directly resulted in warranty claims! If that's not a good enough reason to change your oil at reasonable intervals, I don't know what is.

In other words, cover the OLM with a piece of tape and go back to the days when a person was in control of their OCI, rather than a computer.

The person remains in control.
The IOLM simply gives a less arbitrary estimate of oil life than does an OCI based upon only time or mileage.
Whether the owner decides to change at 50%, 15% or 0% is his decision.
If the owner wants to do OCIs on a time or mileage basis, nothing about an IOLM precludes that.
An IOLM is a useful tool.
One can ignore it if he wishes.

Exactly what I would do if it were in my vehicle.

Almost any car can go 15k miles on a oil. Not trying to be rude but if it doesn't burn it and doesn't leak then it will go 15k. No I recommend it on any car?
Nope

Back when I was 17 I dated a girl who bought a 3-4 year old satarn and had the oil changed once. It was (I believe) conv quakerstate. I know it was quakerstate but I don't know for a fact if it was conv. Regardless she drove the car for like 2 years and one day I get in it and I see she's 20k and something miles. I asked her if she ever changed t and she said when she bought it. Long story short I poured about half a can of b12 in it and drove it 5 miles down to the shop.

Car still runs true story. I believe its the add packages that expire not the base oil. I'm sure you can ruin base oil but it takes far longer.

Call me old fashioned, but I still like 5000 mile OCI's for dino and 7,500 miles for synthetic.

A lot of things can happen in 15,000 miles.

An oil change is the best diagnostic that you can perform.

We're running M1 green cap 0W-20 in my Daughter's Toyota Camry.

She's supposed to drop by for an oil change every 7,500 - but that car is lucky if she shows up before 12,000.

It has 14x,xxx on it so far.

Her last car (Honda CVIC) got mostly 10K OCIs on dino oil because she didn't hold still long enough to get an oil change..... 253K miles later, a deer strike took it out.

Our cars get 5K OCIs on conventional oil. Whatever 5W-20 that's on sale. Purolator standard filters.

Wow - you're using Purolators for 5000 miles and your engine isn't failing due to media tears? You're quite the riverboat gambler!

I know, right?

Not to worry - we're using the Purolator Classic filter - not the PureOne.

Ok, DON'T PANIC! We have enough members here at BITOG to flame you about your extended use of Purolator Classic oil filters. If no others will step up then we will examine the situation with EXTREME CAUTION and go from there. JUST BE CALM!

I think the engine involved and sump capacity are big considerations. The DI engines are hard on oil. I had a 2012 Sonata 2.4L. I ran Amsoil AZO 0w-30 to 7500 miles. The UOA showed a Tbn of 3.2, not done yet but I doubt 15000 was possible. Maybe 11K to 12K. 60/40 hwy/city. ALL of these extended OCI claims have "UP TO" in the verbage. The only way to verify whether an engine/oil combination can extend an OCI is by doing an UOA at the OEM recommended MAX mileage and then go from there.

That's the best rationale for synthetic EP oil and premium oil filters I ever heard.

I wouldn't get dino oil anywhere near your daughter's vehicle.

Also you did well in picking a couple of bulletproof vehicles for her use.

If the Camry is the cartridge style filter version, don't worry about the Purolator scare.

No issues whatsoever with the Purolator L25208 Classic.

 

[MrQuackers]

L25608 I think

Mobil 1 has used their EP brand motor oil and oil filters as marketing tools for this OCI. Then there is Bosch with their Distance Plus oil filter. Amsoil & Royal Purple for motor oils. And finally, you have a few brands that simply come and go over the years.

I like the idea of saving time and resources. Plus, I'm getting to that point in life where I like to have that one big weekend, right about every 15k, when I can focus on all the regular maintenance related needs of my daily driver.

I am this close to signing onto the every 15k dotted line. My vehicles for now are a hybrid and an older Volvo S80 without a turbo.

Any reason why I should reconsider? Any brands I should consider beyond those already mentioned?

Thanks in advance, and hope all is well.



IMO, you are approaching this the correct way; looking at oils and filters rated for 15K miles. That really narrows the field of both. If I wanted to extend OCIs, I would take this approach rather than depending on multiple UOAs to access the performance of "lesser" oils. Oil formulations can change rather frequently, invalidating UOA based OCI decisions.

It's the cartridge filter. Genuine Toyota $5.75.

Yes, that girl could tear up an anvil, in a sand box. With a rubber hammer.

 

[SilverC6]

Typo, yes, the Purolator L25608.

Funny, I use the same "break an anvil" phrase to describe my older son.

 

[macarose]

Thanks, This is not an easy task and the manufacturers have been stone cold silent on this issue. Even the Society of Automotive engineers haven't weighed in on this, which is scary to say the least.
