Summer is Coming, Severe Duty Oil

[linuxgod]

Just a note.. from my understanding for our cam phasing to work the ECU needs to know oil pressure, so it is probably reported somehow.. just don't know if you can then get the data back out via OBD port.

I assume the oil gauge on the dash is actually electronic, not mechanical, so yeah it's probably available somehow. I *assume* it's some CANBUS value but it could be a Toyota PID that OBD Fusion just doesn't know about. The app has an "engine oil pressure switch" PID but the values are just "on/off". If someone figures out how to read this I'd be very interested.

I'll have to check again when I'm connected to the 200. Just checked it now on my phone not connected to the car and it shows, along with option for oil pressure. But don't remember seeing either of those options yesterday on the tablet when I was setting it up.
Appreciate the response back!

Circling back my own post for future searchers.. 2008 LC does not show Engine Oil Temp thru OBDII

Interesting. 2013 shows oil temp as part of the Enhanced PID package (after scanning), but not oil pressure.

From the manual:

"An oil with a higher viscosity (one with a higher value) may be better suited if the vehicle is operated at high speeds, or under extreme load conditions"

Efficiency pressures has been driving the average viscosity down in modern cars. For severe duty use, I'm prioritizing protection and will run 0W-30.​

Since I live in Phoenix and my truck rarely if ever sees temps below 40f between February and December. does this chart indicates that I should be using 20W-50 or is it saying I could get away with 20W-50? I've always just used the 0W-20, but my truck NEVER sees temps below 0f and rarely below 20f but it frequently sees temps above 110f. I'm doing 100k maintenance this weekend so this stuff is top of mind.

I’d run 5W30 if I were you.

20W50 is useful for the red line dune goers in the Middle East.

If you don't tow or do anything hardcore I'd go for full synthetic 0w30. If you do town or do anything hardcore I'd go with mobil1 5w40 turbodiesel full synthetic

I run Aeroshell W100 Plus (which is SAE 50W) in the summer, but as soon as fall rolls around switch to 15W50. Very distinct difference in starting performance with the multigrade oil on cold mornings. I do throw a little Camguard in with the multigrade as well, just for insurance. IO360 angle valve.

Ever tried adding straight 50W oil on a freezing cold morning? Takes forever.

But in the truck, nothing but Toyota recommended 0W20.

I wouldn't go to extremes lest there might be unintended consequences doing more harm than good.

Hot weather isn't enough alone to justify some of the really heavyweight stuff for casual driving. It's for heavy load uses where one's deep into the gas pedal for significant stretches. Activity that builds real heat like racetrack, dune riding, towing extreme loads. Off-road crawling isn't that hard on the motor as the average HP output is rather low in that use case, leaning more on gearing for torque.
