OCI Obsession and loving it!

Wear rates are highest at the front end of an OCI. The longer the lube is used, the lower the wear rates become (irrespective of brand/grade; with limitations).
Well documented and discussed here:

I must admit that was a very interesting article about early oci. I can see there is a lot of analysis done on the different mileages on the engines for the OC.

And logically that would make total sense as fresh oil will strip out the good oils that have coated the internals just to start over again. ( layman's term)

Well I am by no means fanatical about changing my oil at 1K it's just been a strange habit that I picked up last year. I will be pushing out my oci to at least 3 to 5K. Thanks for the article

To the OP.

which is you? :
1. I just like changing oil.
2. I think more oil changes are better for the engine.

To me it is clearly #1. If you think its #2-any "certified" oil expert. (Tribologist) will tell you (as mentioned) there is more wear in the very early miles of a new oil change. So if anything you are slightly "hurting" your engine.

50 years ago I was in your camp. No longer. The longer the better (for me)

Well after reading that article that another poster shared, clearly shows that early oci definitely strips out the oils protection and starts fresh again. So yes more damage is being done by a fresh oil change especially too frequently.

That's interesting, do you think long term use of a product like Valvoline Restore & Protect could negatively impact that tribochemical barrier?

My question would be if a more robust oil extended OCI formulation with a stronger additive package would cause more initial wear such that it is counterproductive to use the EP oil if you are doing frequent 5k interval changes.
 
I have been doing 3k mile OCIs give or take on my Silverado 5.3. I told myself last oil change that I was going to go 5000 miles. I’m at 4100 miles/40% on the OLM and I’m getting the itch to change it. 5k mile OCI would be about 4 months. It’s feeling like an eternity between oil changes.

You should change it when you feel comfortable doing so. Forget oil life monitors that are a wild guess, and don't know what oil you are even using. Or what makes someone else happy, but you do you. Many people would say that I change my fluids too early, they have their opinion, but as the owner, I do what makes me happy.

Most OLMs are actually NOT a wild guess but a well engineered piece of technology that oil analysis can prove is safe. Every car that I have owned with an OLM I have followed it and my oil analysis results have shown that they are even a bit conservative. For example I went 2000 miles extra on my 98 Corvette after the OLM counted down to zero and the UOA showed that the oil was still suitable to go further. So in my experience with both Honda and GM, they knew what they were doing when they developed the algorithm for these monitors.

Again, you do what makes you feel good.
Others, including me, should do what makes us feel good.
Some people also drive on tires almost bald, me, no i don't.

Hello all,
Figured I'd post this for a general census of the masses.
Not looking for any reprimanding on; you are wasting resources, or just flat-out ridiculous and Overkill.

I'm just voicing my oci as a cathartic and a process that I just enjoy performing on my 2024 Rav4 hybrid car, and mostly love the way it runs after a fresh change.

Does anyone else do there oci at or around 1K miles give or take.

I used to run all of the top name brand oils now I just buy a two Jigger, 10 quart box from Costco for $35 free shipping.
All of the reviews on their full synthetic 0w20 oil has been very good.
so I figure since I'm changing so frequently why not just go with a non name brand and enjoy what I do!

I should probably also mention I don't drive much Highway and I let the engine warm up probably too long, and I for sure can smell excessive fuel in the oil.
That's another reason that I have been changing so frequently but it's my obsession.

I know if I ran it on the highway more I could probably burn off a lot of that fuel. Anyway just wondering if anybody out there feels the same way, or am I the odd duck!

I change mine at 3k especially with my DI Honda 3.5L. My ram with port injection 3k also. Oil is cheap. I don’t give .02 about what environmentalist say. Recycled oil has a purpose, turned into fuel oil for ships or heating oil

I’m just saying that they aren’t a wild guess at all. If you decide that you want to ignore them and do your own thing it’s a free country. But just know that these things were designed by some very smart people who did extensive research and testing to verify that they work.
