Engine oil OEM Toyota or Lucas
Right now I have some Lucas High Performance, but the brand is relatively immaterial to me. As long as it's a reputable brand and it meets the spec in the manual.
Do it, new engines throw off a lot of burs and metal particulates before the parts get seated. I changed the oil on my 2023 venza limited at 950miles. Listen to the car care nut master Toyota tech who sez change the oil at first 1kmiles. He cuts open his filter after 1k miles and the filter is full of metal particles.
I just changed the oil in our new 2023 RAV 4 Prime at 1,000 miles, we have been driving in HV mode to run the engine for break in. I also sent off an oil sample, but have not received the results yet. I did open open up the oil filter and found some tiny bits of metal! At least the filter catches it. I have always changed the oil after the first 1,000 miles in our new cars (Toyotas the last 30 years). Also the dealer said every 10k miles but I always do it at 5k.
I feel it is a good idea to change the oil after the first 500-1000 miles.
I do this just in case something got left behind in the manufacturing process that I don't want circulating in the engine.
There is no guarantee this will make any difference in the life of the engine.
I did my 2024 corolla cross at 1300 miles. Will do it again at 5k miles, and then standard 5k after that. Toyota does them at 10k because it saves them money since they give you a couple free ones off the get go.
I changed my 24 Camry hybrid at 1500 miles. The oil was BLACK and there were a fair amount of metal fragments in the oil as well. For me, the cost to rid the engine of th ebreak-in metal wear is totally worth the $30 it cost me to do it.
The car care nut says to do it, so I will trust him. My '24 Corolla SE Hybrid is at 802 miles and there is a 5 quart bottle of Mobil One Advanced Fuel Economy full Synthetic 0W-16 and a Mobil One extended performance high capacity filter waiting for tomorrows early oil change.
First 500-1000 miles is probably a good idea since there are likely metal bits left over from the manufacturing process and, although they get cleaned very well, the oil does a much better job of it and you don't want those bits floating around in yiur oil or in your engine itself.
After that, you can change your oil as often as you want as long as its under ~10k miles. Most people recommend 5k miles bc oil will pick up debris and metal shaving and what not and 10k is a bit long to let it go unless you're using a much higher quality filter like amsoil or Mobil 1. Most full synthetic oils will last longer than 10k miles these days, but I wouldn't push it due to the debris it picks up.
My mechanic added a bunch of Lucas to the oil, which he said might at least quiet it down, and it did. It's quieter now, but I can still hear it at idle.
I mistakenly put 0w20 in ~1000 miles ago, and though my engine hasn't fallen out while I driving I've seen ~5-10% loss in mpgs and it's a little louder than it was with 0w16.
