OBD2 Scanner/App: what sensors/values to monitor?

[Speed3.5]

Around 200 on ~30min drives

What's your oil temperature? Mine is NA and today it went up to 224 at one point during a long drive.

What's your engine OCI and what weight do you use.


In my case atx and engine oil temps are close to each other.
I change engine oil every 3.5k/4mo SuperTech 0W20 Full Synth as it does more short drives around the town (35%hw/65%local).

Record some data and share it if you can.

Currently between 7K and 8K miles. Had a sample analysis done a few years ago and was told that I could go longer. Rarely had to top off in between. I drive 2K+ miles per month and 90% freeway. Been using all major brands of 0w20 full synth around $30. Tried 5w30 once and didn't notice any difference back then. For my current and last round, Royal Purple 0w20 and the mpg has gone up significantly. I was happy at first but then I wonder how thin must it be to achieve mpg higher (35 to 40) than what the factory intended (27/32/29 let's call it 30)? What kind of friction modifier in there works better than LM's formula as an additive (have added that in the past)? Will collect a sample for this round for sure. Can someone else try RP and see what happens?

The plan is to switch to 5w30 and oem filter next. The oil temp is typically 210 for an hour-long drive and over 220 on long drives. ATF temp stays below 200 unless on steep inclines. Coolant temp can be as high as 214 in stop and go traffic. Did you mean using the app to log some data?

I've heard the oil temperature can continue to rise for several hours, but after 4-5 hours it should stabilize.
