An electric motor for an oil pump. What could go wrong?
Toyota's new electric oil pump.
- Thread starter Bill7
- Start date
As discussed many times in the oil forums, the vehicles specifying 0W-16 (and probably some day new vehicles will specify 0W-8), they have design features (wider journal bearings, etc) that take that very low viscosity into consideration. That is precisely why the 0W-16 oils have their own ILSAC rating of GF-6B vs GF-6A for all viscosity above 0W-16. What they are saying is do not use 0W-16 in vehicles not specifying it. You could however use xW-20 in an engine specifying 0W-16. Always pretty safe to go up a grade vs go down a grade.
Yet here we are again
Just go to youtube, search for toyota car care nut 2.5 liter engine review.
He's got lots of YT videos. A direct link to the video you're referencing would be nice.
the last thing that should be powered by an armature. Well except the camshafts......
usually the oil pump gets changed out for low pressure at 300k-ish. Plus some new rod bearings.
This won't end well. Just like Auto Start. Saving six quarts of gas per year, then paying the repairman $780. in year seven for a new starter.
You could definately use 5W-30 (since it's speced for this engine in the UK), with HTHS of 3.1 for reduced engine wear at high temperature / high sheer, but that electric oil pump reducing the oil pressure to 10psi is going to still be there. It's likely these toyota's will get to 100k miles with no problem. But it will be interesting to monitor them from 100k to 200k as the cumulative effects of years with the HTHS 2.3 oil + the low pressure oil pump to see if Toyota engineers really were smarter than we are, or if they were overruled by their management to avoid the CAFE fines.
Yes but I was thinking along the lines of the car engine starting up during the drive due to needed power or battery charging. The engine starts up and shuts off as the computer dictates.
So if you are cruising on battery and start going uphill the engine kicks in to supply power. At that moment I wonder if this electric oil pump is told to come on right before engine start?
I've got a freezer in my garage that has been running continually (other than a rare utility power failure) since 1985. To me it doesn't seem all that much of an engineering design challenge.
I'm not sure if it's been 100% determined if the oil pump is actually an electric oil pump, or if it's an "electronically controlled" variable volume mechanical pump.
An oiling system is "ideally designed" to retain oil in all the galleries, etc when the engine is shut off, so as soon as the engine starts rotating again the oil flow should almost be instantaneous.
if your compressor fails, you lose some steaks & frozen preserves.
if the electric oil pump fails, you lose a $7k-9k engine. And maybe also the frozen steaks you just bought.
I would imagine if it was actually an electric powered oil pump, the control logic would be to shut down the engine if the system saw the pump fail so the engine doesn't smoke itself.
True on the pressure part but thicker oil makes some of us feel better and does undoubtedly have more protection whether it's even really needed or not. But I'd say the latter as they definitely do need to increase efficiency but they're still going to design something good at the end of the day. They have a market mostly based off of quality reputation and the last thing they'd so is ruin that. No one buys a Toyota for sportiness or brand lust like audi or mercedes. People these days buy Toyotas for reliability first and ownership practicality and nothing else really. Toyota knows that and knows better than to make junk that will kill its customer base. Toyota has made mistakes but they're rather quick to correct and almost never do it again in the future. Unlike most other manufacturers.
Sure… if the ECM is controlling. If you are controlling the solenoid/starter motor happens before any RPM and the RPM at that moment is not really the best for the engine. Suppose you push a start button and the oil PSI needed to show before the starter solenoid would engage.
Maybe I am viewing this in a simplistic manner. My thinking is that yes, we push the throttle and turn the steering wheel but a computer is doing all the thinking and intervening. Computers do so much more these days than a basic ECU.
Bro, if we’re going to start worrying about electric pumps moving fluids then we’re all going to be very worried people…
Washing machine pump - electric, dish washer pump - electric, AC condensate pump - electric. Well water pump - yep, that’s electric.
When those pumps fail, the machine doesn't destroy itself like an engine without oil flow.

They have them with over 300,000 miles with no failure. And it’s all electric. Same with cam phasers. Not oil pressure driven. Oil pump is not chain driven.
