I'm starting to think for normal road driving the oil cooler will never let theboil warm up to proper operating temps. I have yet to see more than 185 F. I am wondering what can be done. I am thinking of running less oil on the street. Has anybody tries this? What is your input. Say run 7 qt instead of 8. Oil is still too thick at 185. Needs to be at least 212.

I don't see the problem with 185F. That's where my C5 operates 95% of the time. Same with the C6Z's I've driven. 285F on the other hand...

ZR1's and new Z06's have an engine oil cooler that mounts to the side of the oil pan and has engine coolant running through it. From what I hear it puts oil temp. very close to coolant temp, which is more of the optimal temp for engine oil. Not sure which engine you have - Maybe you could use this or a similar cooler to warm things up a bit?

Here's what it looks like.

From what understand 285f is a great temperature for 30 weight oil. 185 is low. That means high oil pressure which means less actual flow / lubrication. 285 is something you would see at a recetrack

the car was designed and engineered by teams and teams of highly skilled, highly experienced automobile engineers....I think you are over analyzing....

The temps you are experiencing are normal, and you have nothing to worry about.

Fair enough. My ex did say "YOU OVER ANALYZE EVERYTHING" when we broke up. Anyway I just want the maximum amount of lube and from reading Bob is the oil guy info 185 F 30 weight oil is still kinda thick.

120 degree's is to cold, 150 degree's is to cold....

Now under racing conditions....
Endurance: We would like to see 180-195 water temp and 220-245 oil temp and the car can go for hours and hours WOT on track as long as it kept those temps on average.

Sprint: We would like to keep it under 220-230 water temp, and oil temp under 280. No more than an hour at a time.

You also have to think the thickness of the oil is going to play a part in this as well. You wouldn't run a 5w30 at 300 degree's and you wouldn't want to run a 15w50 at 200 degree's as you would be wasting a lot of energy and friction to pump that thick of an oil unless you need it. Other things go into that than temp but the oil does need to be matched to the temp to some degree of what you are running the car at.

So your seeing 185 degree oil temps under normal highway and city driving with the car, using a 5w30 engine oil? I would have no issues with that at all. Keep in mind, the car was built to see the track so it is going to run cooler when it is just cruising around town than WOT 4-7k RPM.

I have noticed on the ZR1 setup, it does warm up the oil quite a bit quicker than the Z06.

Just saying if one is doing normal driving and oil is at 185 then you want to romp on it all the sudden during those brief redlinr moments the oil is not flowing at Max flow. The engine will be experiencing less lubrication and more wear (a very small amount more wear) than if the oil temp was at 212. Anyway I'm switching to 0-30 o might even go to 0-20 to see where my pressures are at because I think 50 psi @ 185 f @ 1000 rpm is too much pressure not enough flow.

Actually with the Z06 I see oil temps around 260 degrees on a hot track day. On the highway the oil is just fine at 185. You should see it in the winter. I have had my car out for 30 mile drives on a cold winter day where the oil temp never got to 140.

Look at it this way 99% of the other cars you have owned haven't even shown you oil temperature so you really didn't know whether the oil was too warm or to cold and it probably never hurt you.

97% of the cars I have owned cost less than 26% of my Z06. I find my care for an auto is directly proportional to the cost/amount of work I did to get it. So yeah you are right I didn't think about oil much in my $1000 Volvo 740. I also had no desire to ream the **** off a Volvo or my truck for that matter.

I think you can trust the fellas at LG.

You're fine as is.

First of all, we are using 5W30 oil, not straight 30 weight. It is designed to flow well at lower temps. Second, you aren't getting less lubrication at that temp, you are getting slightly less power to the wheels as a result of pushing that oil around (that's the higher oil pressure you see as it's warming up.) Last, running less oil is not the answer, if you are really stuck on getting higher oil temps just cover up a portion of your cooler with tape, but 185 isn't a problem.

How about 106 degree oil after driving on a highway for 2 hours in a driving rain with air temps at 34 degrees. Glad that hasn't happened often.

FrankTank

I have this same concern. Here in IL, in the morning even after 45 min of driving to work, temp is about high 30 to low 40's out, my oil will not get hotter than about 145-150.

I also don't like the fact that when I get out of work in the afternoon and it is warmer out..I want to romp on the car right away and it takes too long for the oiil to warm up

Oh well...if it did not have the oil cooler it would be running hotter and we'd all be trying to cool it down with aftermarket coolers

Car was made with track-use in mind so I get it.

can't win sometimes I guess when it does FINALLY warm up outside this won't be an issue. I don't think the car was meant to be driven in the snow or in 10 degree temps anyway

As a general rule, you will not want to get well into the throttle until the oil is at least 160F. 185 is normal for the street. I generally see the oil temp at 80-100F above ambient when driving as normal people drive. That means when it's 40F out, I'd only see 140F and if I want to use the car I'd have to work it a little to get the temp up so I can go WOT. I'm using Mobil 1 5W-30

i run 10-30 in my new forged motor. Charlie Willaims of RPM motors built it. Being that's it blueprinted to the inth degree. my cold pressures are at 80-100 psi. I just don't beat it when it's cold. when it's warm and oil temps are at 165-185 it runs at 65-70 psi in 6th gear at 1500-1700rpms. it idles in town with coolant temps at 180-195 @ 50psi. Even my stock LS7 peged to the gage at 7000 rpms. I asked Charlie and he said it's normal. If it's good enough for him; it's good enough for me.
