How often should you change the oil on your 4runner?

Assuming its an daily driver car. I was told 3 months or 3000 miles but that seems excessive.

 

3000 miles was the rule of thumb back in the carburetor days. It is not necessary for modern engines under normal driving conditions. I change oil when the maintenance reminder tells me too. IIRC, that was around 7k this last time. For a daily driver under normal conditions you will be fine following the vehicle maintenance reminder.

I also like to send samples to Blackstone Labs for analysis once in a while to check for indications of unusual wear. So far I've never had an issue with Toyota engines.

 

Synthetic or Dino oil? Synthetic goes much farther...even regular oil goes to 5k. You won't hurt anything with 3k oil changes...but 5k is fine. Higher with synthetic.

 

Mine is a daily driver in normal driving conditions that requires synthetic (2018).

I change every 10,000 miles.

 

Same

 

What's the manual say in your 3rd gen? I'd be shocked if it's the same as the 5th gen 10k recommendation.

For me I always replace it every 6-8 months regardless of milage as I don't even hit 10k a year.....especially this year as I've put 3k miles on since December 2019.

 

Ah, didn't even see this was in the 3rd gen forum until @aroyalsfan mentioned it.

Disregard my statement OP, as it doesn't pertain to your situation.

 

Hayne’s manual....

 

I change at 5k and use synthetic. First change goes down around 3k.
It’s either very dry dusty or tropical wet humid here. Neither is great for oil longevity.

 

Every 5k with Mobil 1 full synthetic, usually in the high 90s to low 100s here in Mississippi, so i like to keep it clean.

 

Ya, no wonder my engine is running so well. I change it every 3,500 miles. Gonna ride out this next change to 4,500 prob. I’m towing...

 

This may be the first time I’ve every opened this service booklet....

 

I follow the Toyota recs right now since mine is under warranty...will probably revert to my usual 10k interval. that's about 2x a year for me.

 

I use Toyota oil and filter. I change it at 5,000 miles.

 

que grado de aceite utilizan para el motor 3.4l ??

 

I use full synthetic and change it every 5K

 

I put on 12-14K per year so to make it easy, I don't even look at the mileage, just change it in December and then in June using synthetic oil, runs like a champ!

 

I change every 10,000

I use the same stuff in my Silverado.

Castrol 03060 GTX MAGNATEC 0W-20 Full Synthetic Motor Oil, Green, 5 Quart

I change when it reaches a certain color... Between 5k and 8k typically
