For those that advocate 10K miles OCI

[edyvw]

This thread is about toyota recommending 10k OCI, with focus on modern GDI engine.

Actually, N52 was the engine introduced in the middle of GDI craziness, just port one.
It is very hard on oil. Extremely high temperatures (but EU versions I think all have heat exchanger), both coolant and oil. Oil doing good in BMW is going to do good in Toyota, port or Di. Oil doing good in Toyota is not going to do well necessarily in BMW.
So, his experience is VERY relevant.

Whether toyotas piston rings are garbage or not is irrelevant at this point.

Well, modern engines are using smaller piston skirt….

He's a Toyota tech talking about Toyota cars.
Maybe he didn't talk about an 800,000 mi Honda V6 because it's completely irrelevant to a Toyota discussion.

How's that for a narrative?!?

Sorry, I misunderstood the topic. Thought it was about oil change intervals. I now see it's about cars that last less than 150,000 mi.

Have you seen an N52 piston?

 

[KJSmith]

My bmw made it to 241k miles with 15k manufacturer service intervals and is still going strong . Always driven hard, 90/100 mph daily commute for 50 miles.

Highway miles?

Thats a big part of why my two Ecoboost do so well...even with them being GTDI engines.
40 miles each way daily allows the engine to heat saturate on a regular basis.
Highway miles do very little harm.

At the end of the day, know your car and driving style and adjust from there.

We have to many people that want to make blanket statements.

Engine
Operating Conditions
Lubricant

We can all come up with combinations that would or would not likely have problems with 10,000 mi oci.

A blanket statement, backed up with UOA's over a 20 year period.

But Yeah, it's the internet, anybody can say anything they want.
You get to choose who to believe.

Yeah, well, some of those UOA are not that great (high fuel %). I can show you.

You made a blanket statement? I thought you made a statement specific to your engines, operating conditions and lubricants.

People are perfectly willing however to make a statement your OCi is to short or long based on experience (or simply rumor) that was from a different lubricant, operational condition, and/or engine and without any knowledge of your analysis results.

I simply don't believe every 5 000 mi oci is to short or every 10,000 mi oci is to long. Your experience may be different.


I do have a problem with the idea (presented in the video) that all Toyota Vehicles that drive 299 miles a day regardless of lubricant or operating conditions require a 5000 mi oil change.

Hear! Hear!

It depends on what you call high fuel.
I read somewhere that Ford consider 8% high.... yeah, most of us do.

But high fuel that does not affect wear... is that a problem?
My '13 would dilute at times. As far as I know it didn't affect wear.

Both my '13 and my '17 will/would occasionally do the chain rattle... also never affected anything.

Sorry, misunderstanding on my part.

I think we agree that there are lots of variables and it is up to each person to decide what works best for them.
At the end of the day, do what you are comfortable with.... its your money.

 

[tolian21]

But high fuel that does not affect wear

Wow. If we cant agree that highly diluted oil with fuel causes wear, not sure its possible to agree on anything.

Anything over 1% is high dilution in my book. Such oil samples usually have viscosity significantly lowerred below the spec. It will wash away oil from cylinder walls, they will get groves and it will burn oil if you do it long enough. I dont even know why I have to explain this….

 

[doublebase]

Yup, I'm not a fan of him either.

Yeah, he just rubs me the wrong way, especially his earlier videos. He seems to have calmed down a little bit. But initially he was very combative. pompous, self righteous, talked down to people.

 

[doublebase]

Why not just go with the oil life monitor?

I’d love to, however my Toyota doesn’t use an algorithm it’s just a Mileage counter.

 

[doublebase]

You can find a situation that supports almost any position. BFD. It always seems to come down to what an individual believes will work well for them.

I've not seen (at least I cannot recall) anyone being swayed from their position regarding OCIs by any arguments contrary to their position and belief made in any of these threads.

Has anyone changed their position on OCIs for their situation by what they've read here?

I honestly can say that I have changed my position on oil change intervals based off information and perspectives I’ve read in arguments here. I try to keep an open mind, and if it makes sense to me...hey, why not give it a try? Study up on things a little bit that you believe differently. Try them out. No big deal. I’ve done it before, turns out I was wrong. And I’ve done it before, and turned out I was right.

I’m a historical 5,000 mile interval guy. I‘m going to try 10,000 mile intervals for a while to see if it’s ok. I may send an oil analysis in (I’ve never done that before either). I’m usually cost aware. I don’t like to waste money, but then I got to thinking (just yesterday is a good example). Out to dinner with the wife. She ordered 3 drinks that cost more than an oil analysis. Much more. And I ordered two (For about the price of one analysis). Then we went to a craft beer place and she bought 4 cans of cider that was $15 bucks. It was disgusting. Honestly I’d rather drink pond water. So, I’m spending money on stuff that I literally pee away, while it’s destroying my liver most likely. I’ll ”waste” $30 bucks on an analysis, maybe save a few bucks on extended oil changes...and buy more terrible cider.

How exactly without UOA you will know if 10k is OK ? Its not like you will hear or experience something any time soon…

Well, it’s the manufacturer recommended oil change interval for my car. I also bought, and I’m using an extended mileage filter and oil (Mobil1 EP). I do mostly highway driving, very few short trips, almost zero city traffic driving, no towing/hauling.

I’ve looked at almost every UOA for my particular engine online - they are all very similar. I’m also an ASE master certified tech myself that teaches automotive. I talk to techs at Toyota dealerships. The techs I talk to are the ones I’ve trained. I ask them specifically...are you guys seeing any problems with these 10,000 mile oil change intervals, and to my surprise the answer is always the same. No.

Having said that, I do plan on getting an analysis done. The only problem with that, I guess, is that I don’t plan on running the same oil all of the time. I usually buy what’s on sale or rebate. I guess that means my UOA would be useless because I may be using something totally different next time?

Doubt you will see anything major between different brands (as long as they meet all the specs you need). The bigger factor if you change your driving habits.
