That was pretty mellow driving for me, If I run it hard it will hit 220 pretty much everytime.

Very well could be reading off alittle bit.

Wow ! The only time I see mine at 212 or higher is in the heat of the summer 90+° (LOL that's hot here ) or when running long steep hills or towing .

I envy you , as I wish my oil temp was higher ...

Interesting.... Ramnewbie pointed out I am running a 50/50 mix of Redline 5W-30 with RL 10W-30 ....my temps were lower than I wanted prior to mixing in the 10w-30 though ..
Maybe my oil temp sensor just reads 5°-7° lower than others ??

Could a couple of degrees here or there be contributed to the sensors not being exactly identical?

I read somewhere that 220 is the optimal temp for engine oil.

Yep 220 is what I look for at least once every couple weeks I head up Hwy 421 to Shady Valley , as it's all up hill and there's some pretty steep 7 to 10° climbs . I do this to get my oil temp up to burn off condensation. I'll typically only get to 217-219° but in the summer I've had it as high as 228°
I'm typically a very conservative driver ...

My oil will be at 190-205 when the temps are around 10-20 degrees in the morning . Its about a 12 mile drive to work. About 4 miles of it is highway, 70-80mph.

Off topic; These 6.4’s need to be going pritty fast in 6th gear to be happy. 5th gear is comfortable at 60 mph IMO and there is a “dead space” i call it from 60-70 that is a little much for a long time in 5th but way to low for 6th. I desperately need to re gear to 4:56’s.

Currently 3:72’s with 35” tires vs 33” stock.

I don't pray that much anymore, but said a prayer for my oil thread buddy. hope you have an easy hospital day Ronnie

Oil formulations always change, someone who got 300k miles on old formula RP maybe not like new formula RP that has no moly. Someone who got 300k miles on Amsoil SS when it had PAO base with high zddp and high calcium, may choose to not like the new formula that is group 3, low zinc, low calcium high VII's. Researching and making an informed choice is always a good idea imo.

I don't know there is any information that using an oil that eliminates a ticking condition would mean that condition will still prematurely fail, to make that statement is to fashion a guess without all of the information. And it would be equally an uniformed guess to say if your oil ended a tick, that means there wont be a premature failure at some point.

If anything, the old school mechanics rules just don't seam to apply to these modern engines and modern sparce lubrication. In my opinion we have a crisis with lubrication and engine fails. It is either the lubrication just isn't adequate with the thin low additive formulas they now have, or that the quality of the engines are so low they will fail anyway. If the second it true, there is nothing you can do about it. But, if the first statement is true, there just might be something you can do about it. I do find it interesting so many people are brand loyal even when they learn the oil they have been using since the 70's, is no where near the same formula it once was, and they didn't lower the price to match the lower quality either.

I agree with you on the oil formula changes.

On the engine failures not so much, the ones I see involve the cam & lifters.
If it was an oil issue, there would be other failures like rod & crank bearings,
even cam bearings but all the failures I seen reported are the cam & lifters.
Have a feeling the rollers on the lifters are seizing up & not rolling over cam lobes wiping them out plus causing a flat spot on the roller itself . The people this is happening to need to request pictures of the parts that failed when having this repaired to share with us.

Well today I went on an approximate 55mile round trip and I took some pics of my Redline 30wt oil temps ...it's a little cool here today but just to show how cool the oil temps are you gotta watch the coolant temps . You'll see my oil temp is almost always lower than the coolant temps .
Pay attention to the mileage !

The fist picture is about 10 miles into the trip . The next pics are in order and one is in a McDonald's drive though ( for the wife not me ) and the last picture is at home after some very spirited driving in an attempt to get the temps up ha ha the wife almost dropped her drink in the floor type spirited driving [emoji16][emoji16]

Remember pay attention to the mileage and coolant temps .1f647ef7d3ca05c8468dc9c3581c2392.jpg91898da8207bcf6382fbdaed12e9754f.jpg

Notice the above pic , to all that think the " LOL THICK 30wt LOL " runs hotter and this drives up the oil pressure at 70+ mph this pic is for you . This is about 15 miles into this trip and at 73mph the oil psi is 55 with oil temp only 194°

This pic is setting at a stop light after a few miles of in town driving and the oil temp is basically still the same as the coolant.

This one is after going through McDonald's drive through waiting on 7 vehicles in front of us

And finally back at the house after some serious spirited driving ....

Don't put too much stock into the instrument cluster readings... they are mostly BS... Surprise!! You'd have to hook up a scan tool to get the accurate sensor readings. The sensors send a signal to the PCM. The PCM sends a signal to the BCM, and then to the microprocessor in the the cluster itself. The cluster puts imaginary numbers and gauge needle positions up using algorithms to give you warm fuzzies... as long as everything is within acceptable range.

Here are some excerpts from Alldata... there are probably 30 pages worth of in-depth info on how these ticky-dickies work.

Temperature Gauges/Readouts

"The IC (Instrument Cluster) microcontroller smooths the input data using algorithms to provide gauge readings that are accurate, stable and responsive to operating conditions. These algorithms are designed to provide gauge readings during normal operation that are consistent with customer expectations. However, when abnormal conditions such as high coolant temperature occur, the algorithm can drive the gauge pointer or digital readout to an extreme position and the microcontroller can sound an audible alert through the on-board audible tone transducer to provide distinct visual and audible indications of a problem to the vehicle operator. The IC may also produce audible warnings on behalf of other electronic modules in the vehicle based upon electronic tone request messages received over the CAN data bus. Each audible warning is intended to provide the vehicle operator with an audible alert to supplement a visual indication."

Oil Pressure Gauge/Readout

"The IPC circuitry restricts the oil pressure gauge needle operation in order to provide readings that are consistent with customer expectations."

It all comes down to how do you decide on an oil to run. A real oil guy move and a very popular one at Bob's is having a high understanding of engine dynamics and picking the cheapest group 3 you can find. In fact, this strategy at Bob's is more popular then finding the highest quality oil you can find at any price. Problem applications is what really brings the debate to a higher level. I never put this much thought into it until I got hemi tick at 3500 miles of owning my new truck.

I do have a very good understanding of how these systems work ,as I troubleshoot issues just like this for a living . Not automotive but very similar.

I wouldn't doubt at all somewhere in the circuitry one or more of the line replaceable units have a bit more or less resistance measure causing a less than accurate reading on the IC , infact this is what I suspect .


I do like that alldata info , how much $$ is a subscription and how is it broken down ? Meaning is it vehicle spacific , manufacturer spacific or what ?

Can you pull wiring schematics for a spacific VIN ?

Yes, I worked on them for a long time as well. They are similar except the automotive gauges are "heavily dampened" and actually change readings to "meet customer's expectations" because not all drivers are considered "professional" unlike pilots and crew members. In other words, there is no reason to dumb-down aircraft gauges, just smooth them out a bit to keep them from having erratic readings.

The AlldataDIY is great. It's $20/year or $35/5 yr subscription. It's per vehicle. Year, Make, Model. It gives you all info for all options and engines. No, you cannot pull schematics per tail, but they are very nice and in color. They are normally broken down by what engine you have or options as applicable to the diagram. I usually print them out when I'm doing any wiring or troubleshooting. Very low cost for what you get IMO.

That's great , I'll definitely be getting this for my Truck and likely the wife's 16 Challenger as well , thanks !

Off to bed now gotta get up early ... I'm due to be on Dr. Frankinstines cutting table at 0800 [emoji16][emoji16]
