Are the days of the 10k OCI over with?

[jetman]

The last vehicle I had that had the OLM was a 2010 Ford Escape (what a pig). The book said 7.5k miles or six months. Well, at 6 months the vehicle had 3k miles and the OLM went off. So, I guess it did have calendar!

Yeah, my wife only drives her 2012 Lincoln MKX 600 miles per yr nowadays (telecomutes) and the OLM inticates its time for on oil change after 1 yr.
She used to drive it 16k miles/yr and it would indicate it was time for a change after about 8 mths or 9k miles.

My new to me C5 corvette w/5.7L LS1 (w/66k miles since new) OLM currently is indicating 65% remaining. I changed the oil (7 qts M1 0w40 euro) and filter and reset the OLM 5k hwy miles and 10 wks ago. I think it should read 25% remaining.

I'm sending in an sample soon to see what is what.

 

[jetman]

Here the OLM in our 07 Yukon Denali w/6.2L indicates( mostly hwy miles).
8100 miles - 25% remaining
6200 miles - 50% remaining
7800 miles - 35% remaining
8600 miles - 25% remaining
each done in less than a yr.
If you divide the miles by 2 the OLM would be trustworthy.

This week, or at least past few days... This thread is entering Peak BITOG. I'd grab the popcorn but I don't eat popcorn.

I think the snarky ones are clear.

Seriously, go outside or walk around or something sometimes. Wow.

Now, as to 10k OCIs. Here is a video of a visual inspection of oil at ~12.5k.. how does it look?

 

[jetman]

10K mile OCI has been a minimum with my Toyota.

Here's the OCI history of my 07 Toyota FJ Cruiser w/227k miles on its 4.0L 1GRFE.
Dec 2010 - Amsoil SS 0w30 - 17,000 miles
Dec 2011 - Amsoil SS 0w30 - 18,700 miles
Aug 2012 = Amsoil AMO 10w40 - 12,200 miles
May 2013 = Amsoil AMO 10w40 - 14,000 miles
Mar 2014 = Amsoil AMO 10w40 - 15,000 miles
Nov 2014 = Amsoil ACD 10w30 - 14,200 miles
Jul 2015 = SuperTech Syn 5w30 - 10,100 miles
Apr 2016 = Mobil1 5w30 - 11,000 miles
Aug 2017 = Mobil1 5w30 - 13,000 miles
Oct 2018 = Mobil1 5w30 - 14,500 miles
Sep 2019 = Delvac1 ESP 5w40 - 11,000 miles
Oct 2020 = Delvac1 ESP 5w30 - 11,100 miles
Jan 2022 = Delvac1 ESP 5w30 - 10,000 miles
Mar 2023 = Mobil1 5w20 - 6900 miles
I have always totally ignored the OLM.

I bought it used in 2009 with 20k miles. Sump Capacity is 6.5 qts with larger than stock XG8A full flow filter I've been running since 2012 and the EaBP90 remote bypass filter (since Jan 2011) setup. It gets 99% local driving.

It has never and still doesn't leak or burn (consume) any oil.
It's never thrown a check engine light/code. Purrs like a kitten and gets the same 20+ mpg it has always gotten.
The only engine mx that's been done is: 1) I've changed the PVC valve twice, and 2) I changed the copper spark plugs every 50k miles.

"Nothing" the YT Toyota tech says holds true with my Toyota.

I used to do 10k intervals on my Prius because port injected low power no turbo. Now doing 5k with GDI Turbo. DIY oil change costs me $27 and I do it 3x a year. If I stretched it to 10k I’d do 3 every 2 years instead of 6, saving a whopping $40 a year which doesn’t really seem like a good deal to me for the added risk

For the people buying sna….pardon I meant boutique oils, they have to justify the higher cost so running it for extended intervals may seem worthwhile

 

[Cherrybomb]

This was a very interesting post.Lots of good info and opions,no right or wrong answer.It all comes down to each individuals vehicles, miles,are they short or long,is the vehicle under a warrenty.My vehicle,for instance,VW has a 6 year,72,000 mile warrenty.I'm a retired old fart,10,000 miles a year,mostly short,a few 50 mile round trip.VW. says 10,000 mile oil.If I do the 10,000 my oil analsis comes back,fuel dilution.Its thru the Amsoil site,which is Polaris Labs-Oil Analizers.I do the dealer at 5,000 miles.I found what works for me.Another advantage of short sevices is the inspections,a big part of safety.My dealer can be trusted,he knows not to b.s.me.So unfortunately although the oil and filters in todays world are much better,my oil dilution due to short trips and direct injection ,I learned and do what I do accordingly.

OLM accuracy?

Our Yukon Denali I talked about in post# 283 here is hard on oil. Its a large 6000# SUV and even with the conservative way I drive it (at the speed limit & mainly hwy miles) it gets 18 mpg.

Currently it's been 8 mths and 8k miles since the last oil change and OLM reset. The OLM indicates 43% remaining .

* Note * During the 2020 shutdown I increased the oil sump capacity from 6.5 qts to 10.5 qts, that's why this OCI is as long as it is. But the OLM doesn't know I increased the sump capacity.

A few folks here are rather argumentative and childish with memes, some are put off with what they perceive as old people speak, some in fact agree with a few of your points. I find OLMs annoying myself and would rather go by even 5k odometer changes or as close as I can get (ie, 45k, 50k, etc). Thanks for sharing the many firm words. Go have a cold one and enjoy the weekend.

My work here is done.

 

[53' Stude]

If we ask TIG1 I think he’d say with quality synthetic oil, 10k is possible

 

[Slow Car Sport Mode]

Yah! Seriously. Go live life, La Vida Loca, have a car reviewer review your car, kick back a cold one, crack some cheese pet a cat, smile. This thread is like Grumpy Old Men mixed with Gran Torino and balsamic vinegar and Looney Tunes and The Usual Suspects (Keyser Soze!)

Big, Bad Gran Torino. BITOG should be "Get Off My Lawn, Eh?" At least sometimes. Or GOMLE

And the oil can be fine until the TBN is exhausted.

Here's Kia..

 

[Thermo1223]

In fine form as always.

Enjoy your weekend, I'm out.

He really does enjoy arguing with himself.

OLM rarely count down in a linear fashion.

 

[Drewby83]

I still do 10k on our 4.0L 4runner and 5.7L tundra which are easy on oil. I may do 5k on the 1.8L corolla our teen drives due to mostly short trips and smaller sump but could probably do 10k as well honestly.

 

[Bill7]

Prime example my 2015.5 XC60 Volvo which suffers exactly what you mention. At the time I got the car, BITOG was all in the 10k+ rage and how the modern oils can survive for 15k. Many members were even going into measuring contests (or so it seems) regarding how long they can go between OCIs. They would spend more money on multiple black stone reports rather than change the oil.

Sadly I was naive enough to fall into that 10k mentality train and I am paying for my own stupidity. Would the shorter OCI reduce the now hungry Volvo? Who knows.

I sympathize with your situation. Please share with us the brand, type (synthetic, semi-synthetic, or conventional) and viscosity of the oil you were using.

Also, if you had it to do over again from day 1, knowing what you know now, what oil change interval would you choose?

Post in thread 'Which 1qt oil has the best cleaning capability? Redline, Amsoil or HPL?' https://bobistheoilguy.com/forums/t...ity-redline-amsoil-or-hpl.372230/post-6587085

Most likely 5k miles and kept everything else the same. Well ok I would just use one ceratec.

 

[tblt44]

I go 7-8k , my GM 5.3 is easy on oil. I do use full syn.
When I was using blends I would change around 4500.
I know people that just drive, if oil light comes on it gets reset with no oil change till the next time

 

[fdcg27]

While there are edge cases where the oil should see frequent changes, IOLMs have been pretty well validated with UOAs in actual use. As is often noted, a UOA tells you little about the condition of an engine and everything about the condition of the oil.
We all know people who do ridiculously short drains, like the guy who works for me who does 3K changes and we all know people who wait too long, like those who can't remember the last time they had a change done.
As with most things, the golden mean is the path to take, avoiding both extremes.
For most of us, the IOLM works just fine and can be used as a tool to plan a change for when it's convenient to do one.
The drain interval debate is as old as BITOG and is echoed on every auto forum.

You are using premium oils .
