Engine oil Shell or OEM Toyota

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).

I run rotella t6 5w-40, and she loves it

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

10w30 Rotella will cut your oil consumption by 70-80%, ran it in my last Subaru until the clutch went at 234k and running it in my current Subaru

Change the oil with Rotella T6 oil.

Ive used T6 with good results. The major drawback with T6 is foaming, it's less than great in that regards.

I tried Rotella when I first had my truck but it kept smelling like it was burning so I went to Valvoline Full Synthetic since it’s certified for Cummins.
