Oil at 10k service

I'm old school, between 3000 to 5000 or 5 months what ever comes first, more towards the 3000 mark. Many dealers use bulk oil, its cheaper for them than bottled oil.

 

The one common theme I see on all these OCI threads...the camp that advocates for shorter OCI’s bases it on the theory of “why not, oil is cheap, my dad did it that way, I’m not gonna roll the dice” etc. (basically opinion) and the camp that advocates for longer OCI’s is basing it on scientific analysis of actual UOA’s (scientific evidence). For me, I’m comfortable running longer intervals because my UOA’s show a healthy engine. I use the money I saved to buy some Ray10’s

 

Not changing your oil will ruin the economy. Everyone needs a job from the service rep, the mechanic, the oil waste hauler, the refiner at both ends, the truckers, even the damn environmentalists trying to get you to stop early oil changers. Its your truck do what you want with it and stop letting everyone run your life.

 

The majority of all drivers operate their vehicle in “harsh” conditions. Proper preventative maintence is hardly a waste of money.

 

Except its not proper maintenance, its "i know more than toyotas engineers and i'm, gonna change my oil earlier"

Do what you want bub. I'm changing my oil every 10k miles and i'm going to sleep soundly tonight. If you want to call dry pavement a harsh condition to justify a 3-5k interval, be my guest.

 

Toyota recommends changing oil every 5k in harsh conditions.

Majority of drivers actually drive in harsh conditions.

Your self righteous post makes no sense.

 

No they don't.

 

Your opinion vs years of research

 

Ahem. The majority of drivers run on average at 25% of rated power. Nowhere near harsh conditions.

 

Source?

 

I love these threads. Get your oil tested and post your results. Also know every motor is different. I’ve been a fan of 50 mile oil change then whatever the interval is.

 

Id ask you for proof but i’d die of old age waiting for it

 

This is my first with syn. oil and I just couldn't go past 6k,12,18,next will be 24 and I will pay or do it myself.

This is just one article. It is a very common topic in the automotive aftermarket.

Logical thinking comes into play to.

Everyone in the northern states fall into harsh conditions. I am assuming with a user name of Pine State you are from New England. The temperature changes alone make it of the harsher environments in the country.

On the flip side, I don’t recall seeing any evidence proving otherwise. You don’t have to load an engine down or heat it up to drive harshly. There are far more situations in North America that fall under “harsh” than don’t.

 

Well you see... Luckily Toyota has been kind enough to define the intervals of what is harsh and what is not. They specify Perform these service items only if you drive primarily under the conditions indicated.

They include

- Driving on dirt roads or dusty roads - Nope, most people don't do that
- Driving while towing, using a car-top carrier, or heavy vehicle loading - Nope, most people don't have a car-top on a majority of the time nor Tow most of the time
-Repeated trips of less than five miles in temperatures below 32°F / 0°C - Some people do this, but nowhere close to most
-Extensive idling and/or low speed driving for a long distance such as police, taxi or door-to-door delivery use - Nope


I'd say the manufacturer who did all the testing and has to warranty this product is good enough evidence proving otherwise.

 

Extensive idling and low speed driving alone describes thousands of peoples commutes every day into larger cities.

The problem is that people like you are spewing their misinterpretations, misunderstandings, and speculation as fact. While your driving conditions may not warrant shorter intervals does not mean that it is right for the majority. To say it is a waste of money and is stupid is just pure ignorance.

It is not a good thing for people in a car community to discourage preventive maintenance, even if you "feel" its a waste of their money.

 

Toyota wrong, AAA article on the internet correct. Got it.

 

Toyota isn't wrong, your interpretation and overwhelming ignorance of a basic owners manual is what is "wrong". I'm still waiting for you to back up your claims with actual facts and research.

Oh here is some more "wrong" facts on the internet from the people that actually make the filters, including the filters for Toyota: http://www.hastingsfilter.com/Literature/TSB/94-1R1.pdf

There are plenty more "wrong" research studies available for you to dismiss.

Even the Toyota dealerships in New England recognize the region as a harsh environment and recommend the shorter intervals. Saying months of sub zero temperature fluctuations isn't harsh is just being oblivious.

Your sarcasm doesn't change your opinions to facts.

 

I backed my opinion up with verbatim passages from the owners manual. You backed yours up with a AAA article that broadly tries to apply to all vehicles.

Hmm, I wonder why a filter manufacturer would want to suggest you change it more often. What could they possibly have to gain?

Hit me up with some actual information.

 

You backed your information with a flawed interpretation of a basic owners manual.

Using your logic, any information from Toyota wouldn't be viable, as why would they want to increase their cost of ownership calculations? I am sure you think they correct on their "lifetime" transmission fluid. Yet the manufacture who makes the transmission recommends changing it much more frequently. Hmmm.

If you actually provide real facts and studies that the majority of the country does not drive their vehicle in what is considered a "severe" environment, I'll continue discussion. Until then, you are just troll giving an uneducated opinion.
