Engine oil OEM Toyota or IDEMITSU

I change mine every 5k irregardless of whatever Toyota says. Oil changes are cheap insurance to your engine if you intend to keep it for the long term.

Toyota OEM oil has 10x the amount of thr dry lubrication additive molybdenum in its additive package. The dealerships use bulk Mobil 1 oil when they do your oil change. This is why everyone should change their own oil.

Mijn prius uit 2005 krijgt niks anders. Ik rijd er al mee van 220k tot nu 397k. Still going strong!

Use toyota 0/16. Or Mobil 1 0/16. Liqui moly is also very good.

Fun fact, on a gen 4 Toyota Camry (1997-2001) with the 5S-FE 2.2-liter four cylinder, the low oil light doesn’t even come on until you’re like 2.5 quarts low!

I have a Sohn kit and run Idemitsu engine oil in the engine and Idemitsu premix in the Sohn. Runs lovely and smooth and the original cat is still doing the job.

We use Idemitsu for engine oil and transmission and red line for front and rear diff. Red line makes a good fluid for the transmission also.

My 2014 had 226K changed it at toyota every 10K no issues

I check the oil a couple times a month, mostly because it's leaking oil a bit and needs a top-off every thousand miles or so.

I used Toyota OEM oil twice and was disappointed by the way it changed color at less than 5,000 kms. Two different mechanics asked me if I had delayed the oil change. Since then I started using Synthetic 0W-20 and never had any complaints.
