Calcium borate and a molybdenum compound seem to be key to this additive technology. We can’t tell details from UOA, but these elements are all significant in many modern oils. The secrets are probably not secret to the corporate chemists of the top lube manufacturers.
The usual some other market owner's manual.
A continuation of the gross misconceptions about Toyota oil pumps here. Your statement shows you don’t have a clue how it actually works. If what you say is true then there would be widespread failures here in the north during winter. Or summer for that matter.
Mobil1 0W-8 has around 4x variation in thickness simply going from 104F/40C to 212F/100C.
I suspect Toyota knows a thing or two about how to keep engines alive.
Well, according to folks on the internet, Toyota has designed some very fragile engines and oil pumps. Some say it’ll wear out immediately after the warranty expires if you use thinner oils. And yet others say it’ll explode if you use thicker oils. Quite the paradoxical design.I suspect Toyota knows a thing or two about how to keep engines alive.
I believe the common Internet consensus is that you'll shear off the oil pump drive gear.
they are indeed dosing the additive levels quite heavily.Purchased it 2 weeks ago , it’s not my aunts Prius.200 hp , quiet , nice drive.
850 miles on it, will do an oil analysis now. The 0w8 is like water , obviously, but the new oil is very dark in color. There must be a lot of additives in this oil, Toyota oil, made by Mobil 1 …..
And because both of those groups are on the internet, they are wrong. It's not a paradoxical design. THe VVT doesn't suddenly blow up even you use a thicker oil. Nor does the engine suddenly explode one mile after warranty expiration if you use the thinner oil.
Yeah. You’re plainly stating what my paradoxical comment is meant to jokingly allude to. The various unfounded internet theories and misconceptions have created a hilariously false no-win oil viscosity paradox.
Like Ford V8s used to do?
How old is that page? Seems like they should be talking about SP. At least they are offering higher viscosity choices.
What does that have to do with it? Does Toyota get their engine designs and parts from Ford?
Because SP didn't exist with 0w-8 which is a listed grade when the manual came out so they can't say to use SP because one would have never found 0w-8 with SP and they don't want to say to use a non SP 0w-8 but to use an SP 0w-20 or higher since that would become too confusing. Instead they say to use 0w-8 with glv 1. It's a 2022 model year and api didn't recognize 0w-8 and 12 with api SP at the beginning in 2020. Only after 3 years from release did api recognize 8 and 12 grades in SP in late 2023 though the sae recognized 8 and 12 as grade a decade ago. With SQ did they recognize 8 and 12 from the beginning but jaso glv is its own thing.
THere's something called temperature sensors that feed information into the ECU
