    What do the oil experts say about Pennzoil 0w-16? That’s what I plan on using but still have some changes of Toyota oil stored.

    If you're talking about Penzoil Platinum 0W16, I wouldn't hesitate to use it, because it is a full synthetic. I have been using only synthetics for almost 30 years, and I've never experienced engine wear.
    The added benefits I find, are better starting in bitter cold weather, and longer intervals between oil changes.

    Pennzoil is underrated and I love it because it is slightly cheaper than Mobil 1 but better than most group III oil. Penzoil Ultra is GTL which has very good base oil and need less additives to keep it good. Additives are the one degrades over time not the base oil. Gas to Oil (GTL) is very clean and have very homogenous size, very close to PAO.

    That’s a benefit I see also, made from natural gas. But people are talking about additive companies doing the leg work so I don’t know what the h..is going on. I’ll probably use Pennzoil 0w-16 and get it with a rebate.

    Pennzoil Platinum and Ultra are regarded as one of the best synthetic oil you can find in Walmart. It is often better than Mobil 1. If I choose Mobil 1, get the SUV and Truck, it has the longest oxidation lifespan and antiwear. Do not ever add any Home chemist (Lucas, hotshot, Ceratec,etc.) additives, it will destroy the formulations and can cause serious damaged.

    Thoughts on Costco's Kirkland oil? Says Warren on the bottles.

    Personally can't say much about Kirkland oil but Pennzoil Ultra Platinum is excellent. Mostly used it for the last 200k km in the Civic. It didn't burn oil both with Amsoil SS and Redline HP and sure doesn't burn oil with Pennzoil UP. I'm planning to use it in the Prime too as i have a stash of it, prior experience says so far so good (Civic, sister's 2021 Prime and both my brother's CX5 and father's Turbo CX5) and the price is really good once in a while at Canadian Tire (more or less 40$ for a 5l of UP with a mail in rebate of 15$ from Pennzoil)
