Engine oil OEM Toyota or OEM Mazda

I have a 2016 Corolla and just had the oil changed at dealership at 188000 km. Worked out for me.

I'm from a Toyota family. My parents used to buy Toyotas just out of warranty and never did any maintenance on them. When an oil change interval was due my dad checked the oil levels and maybe topped it up a little if necessary - like once a year that is. There was never an engine problem.

If it\u2019s a Toyota it will run just fine even with chewing gum instead of oil, a Subaru will explode one mile past the due service mark.

See how much metal that 08 weight pisswater has generated after only 1.3k miles? Switch to 0w30/5w30 and you'll see a drastic reduction in wear. I know I did.

Forgive me but I’m confused. The Tundra doesn’t have two separate oil reservoirs that I’m aware of and I change my own oil. Also, for what it’s worth mines been flawless since 2022 and almost 40,000 miles (not that that is a lot but just saying).

While I didn't own a 2018 (mine was 2013 hybrid -> 2022 prime), here's my short list:

Electric gives a huge increase in torque from 10-50mph

Mechanic told me the oil came out barely darker than it went in on the last change. ~80% electric miles

I’ll do the 15k oil change soon with Toyota OEM 0w-16, which is made by M1 but has a much higher moly content than the regular retail M1 oil.

I personally am changing my own oil with full synthetic on my 23 2.5T every 6000 km or so. No need other than peace of mind for me. Doing it myself only takes 30 minutes and $35 in oil, filter and crush washer.

Never had any luck doing an oil change every 10K miles on any cars in my fleet. However, with a new car that’s hybrid that I bought last year, I’m praying that I can push the oil change interval every 10K

2000s Toyotas. Not really unreliable, but oil burning was an issue on most of these because people did not change the oil on time.
