Engine oil OEM Toyota or PENNZOIL

Any LL-01 5W-40 is technically suitable and approved. I use Pennzoil Platinum Euro 5W-40 in the N55 and previously used it in a B58 540i. There are other options as well.

Try Pennzoil Ultra Platinum next, I have used it in my WRX and I'm super happy with it. It literally makes my engine run quieter.

I found a dealership that sells the Toyota oem at 5.90 a quart so that’s what I use. It’s made by Mobil 1 but has certain additives added specifically for Toyota specifications that regular Mobil 1 doesn’t have. Technically it’s what the 4Runner will run best with.

Toyota synthetic. I was going to do Mobile 1 but noticed a few claims of people using both saying it shifted a little more smoothly with the Toyota oil

I use Pennzoil in my cars because it won project farm's oil showdown.

Pennzoil Platinum Euro is one of the best oils available as far as NOACK is concerned. It meets most if not all European car manufacturers specs and is the factory fill in Fiat/Alfa engines.

Tie between Royal Purple or Pennzoil, choice usually based on availability or sales. I might slightly favor Pennzoil due to its connection with Shell as I exclusively use Shell 93 fuel for the additives.

I change my oil at dealer every 10k miles. This time I am going to pay $299 for a package of 5 oil changes, with tire rotations, filter and all liquids fililled up if necessary.

My engine is happy with Pennzoil Platinum. No leaks and minimal oil consumption.

While any oil can work for your car, the current best option in the market is Pennzoil Ultra.
