It's one of the best oils on the market...

Yes, I noticed that too. I drive with that oil the last 3-4 years.Noticed the other day that Mobil 1 changed the data sheet for Extended Performance 0W-20 and the 100KV is at 8.3 now instead of 8.8.
8.8 one day and 8.3 the next. What a difference a day makes.![]()
A good reason not to buy Mobil 1 oils.Noticed the other day that Mobil 1 changed the data sheet for Extended Performance 0W-20 and the 100KV is at 8.3 now instead of 8.8.

As others have already noted this makes no sense.the stuff is not designed for modern day direct injection engines.
fine for older stuff
I’m still waiting for his explanation for that statement…As others have already noted this makes no sense.

Just for the record, my car and any other Toyota with 2AR-FE engine (Camry, RAV4) has a variable displacement (VD) oil pump, not a positive displacement (PD) one.Assuming a PD pump, as long as the pump isn't on the relief, both oils will flow the same, as the pump will move the same volume of oil per rotation regardless of the visc.
Many (most?) of the VD pumps just have a variable location "chamber" that adjusts the amount of maximum permitted oil pressure, like a variable relief. The pumps themselves are still a gear-type PD unit.Just for the record, my car and any other Toyota with 2AR-FE engine (Camry, RAV4) has a variable displacement (VD) oil pump, not a positive displacement (PD) one.
Meaning - it supplies different oil pressures regardless of engine speed. That's how it compensates for lower grade oils like 0W-20 by increasing the oil pressure at lower RPM.

There's a thread on the Toyota pump here:
I saw this topic came up again recently. I recall a long thread last year that I thought put this to bed. But I guess not. The electronic oil pump speculation appears to be based on a video by the Car Care Nut saying the oil pump was electronic and calibrated for 0w-16. This being the reason for strict adherence to the 0w- 16 oil (not here to debates that specifically.)
Searched YouTube to try to find this video and figure out where this came from, but instead found this.
A video of the Car Care Nut assembling the A25A in question and talking about the oil pump chain...

Yeah, but in the guy's defense, these VD pumps do seem to confuse a lot of people, that's why we seem to have endless discussions on themIt would be profoundly stupid not to use a PD pump.
