2022 Corolla Cross HPL PP 0W8 20,080 Mile OCI

It's hard to really say. In Amsoil's defense, they do give you some valuable proof of performance testing as I mention quite frequently. I personally value that. I feel Amsoil is somewhere between Mobil 1 and HPL. Mobil 1 is the rules based approved lubricant using the latest chemistry. Amsoil still has a SA of 1.03 (was 1.06) and HPL is the rogue renegade doing things they feel is best despite any regulatory hurdle.

If you've noticed, Amsoil has changed their "one size fits all" approach as they now offer a complete Euro line, HM line, and Hybrid oils. This is a deviation from the old school approach they used to follow.

Amsoil also has an in-house testing facility which is highly valuable.

So all in all, its hard to really say.
 
The thing I like best about this thread…the guy drives a lot, and he’s not afraid to test equipment to its limits. I love that stuff (and because he drives so much we don’t have to wait long to witness the results).

Thank you. Intelligent, cordial discussion on both things technical and pedestrian are a welcome sight.
 
Thread revival!!

Might just try this on my 2024 Prius Prime.. Now, if only AMSoil or Pennzoil could easily sell 0w8 in Canada as OE Toyota 0w8 is on national Back Order since god knows how long... Interested to see AMSoil Hybrid 0w8 VOA if somebody saw some pass around.
 
I prefer to use 5W-30 in all my vehicles for the higher HTHS. I wanted to buy a Toyota Corolla as a commuter car.

I just bought a 2008 Toyota Corolla CE as it's the last year Toyota actually speced 5W-30 in the owners manual,
and it was the last year of the "spin on" oil filters on the Corolla.

It has 60,000 miles on it, and I plan to drive it 20,000 miles a year for 7 more years while commuting.

From 2016 on, the spin on filters made a comeback on the Corolla.
