The old 5k or 10k oil change debate

Possibly more important than total surface area of the filter element the “type” of filter media may play a larger role. Generally, there are two types of filter media- cellulose and synthetic. They say one is better than the other.

Wix filters for example. 51393XP is synthetic where 51393, no XP suffix, is cellulose.

 

Yep, you don't want to use a roll of toilet paper, especially if its charmin.

 

No no no no no...
That IS NOT the TW way. Never has been, never will be.
Just about every topic that gets "discussed" on this forum turns into the same shit lol.

 

I looked at that TSB and can’t see how it relates to the video at all. The TSB covers to 2011 models and the fix was upgraded pistons and piston ring sets (new part numbers). The video is a 2015 Camry. By 2015 they wouldn’t have been using the problem parts they would have been using the lastest pistons and ring sets.

 

LOL!

On a sad note...you are correct in your overall opinion about how things turn sour.

 

Good point but the video doesn't relate to our trucks either... Yet everyone keeps saying here's why I do 5k and using it as a justification.

 

Not sure folks are using that as “justification” since none of us have to justify the decisions we make to anyone here, I think it’s more to inform that the Toyota Master tech has an educated opinion that’s worth considering. No different than someone pointing to 10k/1 year OCI in the manuals (while failing to mention the 5k/6mo conditions that may apply.)
Pretty sure at this point with all the OCI threads people have their minds made up by now lol.

 

Lol how long did it take Toyota to include 3rd gens in the fuel pump recall? They were installing the same recalled pump a decade after the first ones were recalled, so there is no reason to believe they would install the upgraded parts stock. If you spend some time on the rav4 forums you will the same problem being reported in later models. Also given that it was a TSB and not a safety recall Toyota had no reason to extend it to later models even though the problem persisted. There are also several other problems with the video, like calling a vehicle maintained with the cheapest oil available and ignoring a serious oil consumption problem till the seized piston rings destroyed the block "impeccably maintained". I think that falls under the category of owner neglect, not impeccable maintenance.

Also this.

 

I get it. No one is going to change your mind about OCI, nor should they try too. Conversely you can poo-poo any mention of 5k oil changes until the cows come home and people still gonna do what they’re gonna do, based on their research, experiences, and biases. Such is life.

 

Well, to be fair the owner of that Camry and I suppose also Toyota would deem that the vehicle was impeccably maintained, since every service was completed (between two dealerships). Also, until the owner first started noticing oil consumption, how would he know or even suspect he had a problem? Also from the video, it was stated that the vehicle was brought in for consumption tests twice, and that oil was being topped up regularly. That doesn't sound like neglect to me. I don't think you can reasonably lay the blame at the owner's feet.

 

Hi everyone, just checking in to see who won.

 

I really haven't advocated for a specific OCI (on this thread at least). That video was just annoying me because I doesn't have much to do with our trucks and has some odd discrepancies in it, but if you MUST know my opinion everyone should do oil analysis tests to work out the best OCI for there engine, because every engine is a special little snowflake, and what works for one my not work for others.

 

Are these issues being seen across the whole 3rd Gen run, or just earlier engines?
I guess it would also be notable if other vehicles with the 2GR-FKS are experiencing the same problems.

 

lol

 

It's TW. Therefore the answer should be obvious. Nobody wins.

 

The winners are those who just go with what the OCI they prefer and only post info for others to consider if they wish to. The losers are those who have an innate need to convince the rest that only their OCI is the correct answer, because TW folks gonna do what TW folks do, lol.

 

The takeaway of the video for me was that the owner apparently followed the dealer-suggested maintenance to a tee and still ended up with these oil consumption issues at a relatively "low" mileage. Ahmed said that it was his informed opinion that 10k mile oil changes were at least a contributing factor to the ring wear observed on this engine.

Whether these issues are a result of the 10k OCIs or some design flaw particular to the 2AR-FE might be deserving of further research, however.

It seems like Toyota never could get those Camry 4 cylinders quite right after the 5S-FE in the 3rd gen Camry. After that they started having various issues like headgaskets and oil consumption. But this is just from my research online; it would be interesting to see if @Bishop84 has observed this in his work.

 

Well put.

Alright so what next, politics or religion?

 

Ya the master tech didn't include some perinate information like at what miles the consumption test was done and how many miles it drove while consuming oil, but from the way he described the problem it sounds like the consumption got worse and worse till the owner couldn't keep oil in the thing. Which would definitely be neglect in my book.

 

Oil brands. lol
