I prefer 7,500 mile interval. I feel like 5k is just too early, and 10k just seems like a bit too long. At 7,500 when I do my oil changes the oil still seems pretty clean and filter looks to be in good shape. My 2012 is at 105,000 miles.

I do it as close to 10k as possible, 2016 sr5, 178k miles

I do about every 10,000 miles. I don't think I've ever sent in a sample from the 4Runner, but I do 10k intervals on our Rav4 as well and have had it tested by Blackstone and reports always came back good, so I'm pretty comfortable following Toyota's recommended intervals.

Some great responses. So far 20 people do 5,000 mile intervals, and a cumulative 34 do 6,000-10,000+ intervals. Sounds like a lot of people with intervals between 5k and 10k do so for "timing out" reasons.

I use the time interval and do it annually only because I only drive around 4k per year. If I drove more I'd change every 5k>7k probably. 2012 SR5. w/56k on the clock

I did 10k when I was strictly dailying it, but since I started wheeling I’ve gone down to 5k intervals.

I’ve never had issues with 10k intervals and have always stuck with that.

10k intervals using TMO 0w20 until recently. Now doing it at 7.5k intervals with 167k on the odometer. Runs like it did when it was brand new.

Every 5k miles. I have it lined up with every 5k on the odometer. I bought it in January with 50,000 miles and just crossed 60,000. With a couple road trips planned soon I’m thinking I’ll be close to 15,000 miles on the year. I do drive it somewhat hard.

179000 and a steady diet of Mobil 1 0w-20 extended performance every 10k. A few 15k intervals when I was doing a lot more miles per month. I'm back to 10k intervals now that I'm driving less.

I can remember multiples of 5 easily... but since I'm in Canada, I do the oil-changes every 5,000km. Thats like 3,000 miles.

Clearly, I'm on the conservative side of things in this thread :-O But I also grease all 6 driveshaft zerks while I'm in there, and all 6 JBA upper-control zerks too. Sold my last 4x4 at 20yrs of age to a student, and it's still going strong... I have high hopes of getting 30yrs from my 4runner

I did about a decade of 3000 mile changes on other vehicles but when I started driving over 600 miles a week, I switched to synthetic and 5K changes. Every 10K is a tire rotation so that's easy. I've never gotten rid of a vehicle with less than 200K on it. I figure someone else can enjoy the golden years...

Nah, that's just to go get your floor mats checked ;).

For me, 10K interval +/- a couple hundred. Coming up on 52K miles on a 2020...

If you read your manual the recommended oil change depends on how you use your 4Runner. If it primarily a commuter car where most of the driving is highway it recommends 10k. If most of the driving is in the city or locally it recommends 7.5k. If you do a lot of towing it recommends 5k. I think the reason many people, like The Car Care Nut suggest changing every 5,000 miles is it simply takes all the guess work out and ensures your oil is in optimal condition.

For me I do it every 5k. My tire shop does oil changes so I have it changed there and get my tires balanced, rotated and recheck my alignment. An alignment runs about $120-$125 in my area but many tire shops are now offering unlimited 5 year alignment’s for about $190 which I did. So now when I take it in I get everything done at once. Makes it easier to keep track of things.

Oh and I’m sure most of you already know that most tire shops offer you free rotation and balance for the life of the tires when you buy the tires from them but many do not do oil changes or alignments. If you’re looking for the convenience of having you oil changed and tired rotated and alignment done all at once it may be something you want to consider when buying new tires in the future.

I was changing mine every 10k, but the oil seemed a little dark, so I've since switched to every 5-6k. Not a huge difference going to the shorter interval, but drive a good bit on forest service roads so figured it couldn't hurt. 125k on my '14

Number one reason for oil change....contaminants. Contaminants in the oil is the main reason conventional oils were swapped out at 3000miles, as well as blended oils at 3000miles and full synthetic at 5000....no later. Look at the oil at 5000, its DARK brown to black. Cars are expensive enough, why get lazy and fooled into thinking 10,000miles is a-ok...it's not and it's pay back will hit you in your wallet.
I do my own oil changes on my 18 4Rnr, and my sons 07 4Rnr. I installed the Valvo Max oil drain system on both. Super easy and no spills. The only issue is my 18 with that stupid, stupid oil cartridge system, what a stupid design and major pain in the ass to deal with. The 07 4Rnr is sooooo easy in comparision.
