Oil Change Interval (1 Viewer)

[mjosoba]

Morning all. I’ve strayed over here from the 80 section. My wife just leased a 2023 T4R and we were talking to the sales guy. I had to ask him a couple times to make sure he wasn’t mixing them up. But he insists it’s 10,000 mile oil changes and 5,000 mile tire rotations.

Why on earth would it be this long? I’m thinking I’ll just change it myself at the 5,000’s between the 10,000’s. Is there any reason this would void their warranty?

My wife thinks she’ll want to keep it after the 3 years is up, and if we do, I don’t want a vehicle that’s only had 3 or 4 oil changes in that time.

they have to keep the machine going somehow.
imo 5k is too long for oil or tires.

I do mine 5,000 miles

Their US Marketing team created that recommendation to keep initial ownership costs down. I would go with 5k oil change and tire rotations. And I know this is a lease, but if you keep it I would recommend changing all fluids - transmission, transfer case, diffs, and radiator fluids - every 60k. Keeps everything nice and happy through stratospheric mileages.

hes right, thats the factory recommended service interval. the trucks running synthetic oil so you can get away with a longer service interval, personally i change the oil in my wifes car every 7500 and just rotate as needed. you can do the services yourself but you wiould need to keep records of what youve done with receipts to show that the vehicle has been getting serviced.

I change mine every 5000 and it just so happens that is when the maintenance minder comes on.
I would never wait 10K miles between oil changes.

The salesman is correct but I agree with others that you should do it every 5k or 6 months.

10k normal, 5k severe duty is correct. Toyota has a lot of engineers, a huge set of data, and does extensive testing. I suggest trusting the people who are the experts. 10k is fine for most use. It's the standard for all Toyota's with synthetic fluid IIRC.

IMO the best bet for evaluating service interval is to use mpg as your guide. Start with 17mpg as the baseline for 10k oil changes and adjust interval relative to mpg. For example 8.5mpg = towing = 5k oil changes. 14mpg = 8k miles. Etc.
This is based on the study by Cummins IIRC that heavy truck mpg was the most accurate predictor of engine oil life. They started at 40k and 8mpg I think and adjust from there.

I did my first change early at 6k or so. Then 10k adjusted for duty like heavy towing use. I've never had an issue with a Toyota using Toyota's service guidelines. The two million mile tundras used 10k mile oil changes.

Good luck.

Oil and filters are cheap. There is a BIG difference in cleanliness and long-term engine wear between 5K changes and 10K changes. All of our rigs get a 5K change. The Toyota "normal duty" recommendation is more or less just for easy highway use.

Those million-mile Tundras were 100% highway rigs that might have racked up 10K miles in a few weeks with only ~10-15 cold starts. For most DD rigs, 10K will be 6-12 months with hundreds of cold starts and short drives, which are much harder on the oil and engine.

Yeah, I always imagine it’s stuff like those guys who escort turbine blades and all they do is cruise along at 70mph day after day. I do our Subaru at 5k, much happier than it was at the 10k, then changed to 7500 by Subaru. The LC gets it at 5k as well. Oil is cheap, and I’ll just do it myself at 5000k and take it to them for the 10k’s.

The devil is in the details/fine print

What toyota considers to be severe duty is pretty much anything but highway driving and they have specific scary language I recall reading in the new vehicle propaganda that suggests they will absolve themselves of any warranty responsibility if folks dont change early/often.

I'm pushing 80k and have been doing synthetic oil every 5-6k

Intend to send a sample off to blackstone for next couple OCI's before I hit my 100k warranty mark just in case.

Fingers crossed.....I'd like to drive this vehicle to 500k and beyond

I need to read up on it more, and also find out if they will take issue with me doing it in between their required changes. . I’ve got a ton of 0W-20 FS from work that we use in our Subie. I actually deliver the bulk 0w20, 0w16 and 5w30 to the dealer we bought it from.

From having owned multiple Subarus, they really need no more than a 5K change. They all seem to burn nominal oil til around 4K, after that they seem to rapidly accelerate oil burning. This has been my experience on both EJ and FB-series engines. Not sure if the boxer shears down the oil or something else. My 2UZ does not seem to have that problem - the oil slowly gets darker, but the level never drops.

Definitely my experience too, with our FB25. I found that it ran through mobil 1 to the tune of over a quart every 700 or so miles. We did two oil consumption tests through Subaru, and it miserably failed both. I figured if I was going to burn that much, I’d use our oil from work since I could get it so cheap. We also deliver to Subaru. Ends up that oil is fine until around 5,000 or until I do a prolonged trip at 80mph+ of at least 800 miles. Usually in one 5k oil change I’ll have to add about 1/2 a qt, up to a full qt if we head out and back to CO, or MI or similar.

Edit: Really very few complaints about the FB25. It’s a heavily favored contender for a swap into our Westy.

i think the only thing that would be an issue with that would be not having it documented if your doing it yourself. you can claim that you do the oil every x miles but with no proof its just words

 

[Masonblackmon]

A lot of these newer vehicles have longer periods between Maintenance.
For example my mom has a Lexus rx350 and it’s recommended that you change the oil every 10,000
My f250 diesel is the same way with the transmission fluid interval at 125,000 instead of the old standard 50-75000 miles

Are receipts of materials purchased proof enough, you think? I’ll have to talk to my old boss, he is the parts management EO for the series of dealerships we bought it from.

 

[bigredmachine]

should be, whenever we had someone come in trying to make an extra care clime and there was engine damage if it was serviced at the dealership it would show up in the national records for the car. if there was no history they would have to bring in receipts for parts or from an outside shop if it was something that they couldnt or wouldnt do themselves. obviously their not going to warrantee am aftermarket part that you bought but if its a factory part there will be some warrantee on the part

Toyota has been running a 10k oil interval for years. Here is something you need to keep in mind if you are going 10k. You must check the oil between. It is not uncommon at all to go through at least a quart between changes. No big deal for most. Howver, I’d guess 90% or more of our customers NEVER raise the hood themselves. Therein lies a huge problem with the 10k oil change. Most manufacturers allow a quart of usage every 1k miles. So in theory, you could be out of oil at 5k miles. I have not seen this, but I have seen some go through 2 quarts between 10k miles. And some customers go off about this. It wasn’t that long ago that intervals were 3k and it was considered normal to add a quart between. Now, at 10k if a quart has to be added it’s the end of the world. You should have 2 years or 25k miles of complimentary service on your new 4runner. Just make sure to check the fluids yourself, even after service. I have seen techs miss checking the oil at 5k. I spot check ours every so often, as much as anything so they know I’m always checking their work. Enjoy the 4runner.

Good points. This is another reason I switched our Subie and my moms hybrid Camry to 5k intervals. They were burning a lot of oil, and I was adding a significant amount. Both engines, FB25 and 2AZ-FXE, have known oil burning issues. The Subie rarely burns any oil until shortly after 5k miles, and the Camry seems to still burn about a qt. But either way, I’d rather just change it. There is a significant amount of impurities trapped in that oil, and I’d hazard a guess it’s exponential the further you push it. I don’t see how 5k intervals could ever be a bad thing, and oil is so cheap, I’m content with that.
