Proof Readers needed for Ask Tadge Question - Engine Oil Cooling
I am planning on submitting the following question to Ask Tadge. Can I please get a few people to proof read my question? On the C7 I am not sure if the coolant/oil cooler assembly is used on all C7's or just Z51 and Z06 C7's. I want to make sure I have all my facts straight before I submit the question.
**************************************** *********************************
I have now moved this question to the "Ask Tadge" section. If you would like to make a comment please do it there. Here is the link.

For many years GM has used radiators with an engine oil cooler inside left tank for trucks, SUVs, and in the Corvette C5 Z06s.This method of cooling engine oil works well and has the added benefit of warming the engine oil during warm up. It also keeps engine room congestion and the number of pluming connection to a minimum.
The 2006 – 2010 Z06s use a large air/oil cooler mounted in front of the radiator. This method of oil cooling works well at the track, but in normal street driving it keeps the oil too cold. On a 50 to 60 degree day, it is common to see oil temperatures in the 130 to 140 range (DIC). The DIC is reading oil temperature from the bottom of the external reservoir, oil then goes to the oil pump ,to the oil filter, to the oil cooler, and then into the engine so the temperature of the oil entering the engine is even colder than what the DIC says.
The 2011-2013 Z06s, 2009-2013 ZR1s, and C7 Z51s/Z06s uses a coolant/oil cooler assembly to cool/warm engine oil. This method needs to have a coolant line plumbed from the block to the cooler assembly and from the cooler assembly to the radiator. The cooler assembly and extra plumbing add to engine room congestion and increased potential of coolant leaks as time goes on.
The current Camaro Z28 uses a bigger oil coolant/oil assembly than the Corvettes.
Can you please tell us the advantages and disadvantages of each oil cooling approach from an engineering point of view and why you changed the oil cooling approach so many times?

I think you mean plumbing not "plumping"
Also, don't pay to much attention to your DIC. If it's anything like mine, as soon as I realized I had one, it developed a mind of it's own.

BTW, I recently called Mobil 1 tech phone line and while I was waiting 4 techs conferred as to whether 150* F is too cold for engine oil and they declined to say one way or the other. They suggested I ask GM about the proper oil temp which is exactly what you are doing.
Your Qs are good ones!

My suggestion: You're drawing a conclusion stating that it's too cold. Instead of declaring it so, let's ask them if it's too cold, let them tell us.

I look forward to seeing his thoughts on oil temperature as I intend to install a thermostat later this year (I already have a dry sump tank preheater and an oil cooler cover and posted a temperature graph here). This might also be an opportunity to get an update on his valve/guide investigation as low oil temps are potentially a contributing factor.

I think a better question would be what oil temps GM likes to see. You kind of answered your own question in the question. Seems like you already know what the advantages/disadvantages of a air/oil and water/oil setup are.
From the OEM perspective, cost trumps all, so I would bet converting all of them to the same style water/oil cooler allows them better purchasing power and lower cost. The large air to air specifically for one car is probably more expensive.

Ya like others say one shouldn't prompt the responder with bias. The C5Z06 oil cooler "works well" is subjective. Most of the C5Z06 tack guys I know have to mount another cooler where the license plate cutout goes, so not sure how well it works.
Most likely he will have to put forth a politically correct response.

What temperature is too cold, the engineers may not consider the level you are talking about as too cold.

The 2006 – 2010 Z06s utilizes a large air/oil cooler mounted in front of the radiator. While this method of oil cooling seems to work well at the track it’s application in normal street driving seems to keep the oil at a much lower temperature. As an example, on day’s where the temperature is 50 - 60 degree’s F., it is not un-common to see oil temperatures in the 130 to 140 F degree range (DIC). While the DIC is reading oil temperature from the bottom of the external reservoir, the oil first travels to the oil pump, then thru to the oil filter then thru to the oil cooler before it enters the engine The temperature of the oil entering the engine is colder than what the DIC says.
The 2011-2013 Z06s, 2009-2013 ZR1s, and C7 Z51s/Z06s use a coolant/oil cooler assembly to cool/warm engine oil. This method employs a coolant line plumbed from the block to the cooler assembly and from the cooler assembly to the radiator. The cooler assembly and extra plumbing would seem to add to engine room congestion with the added potential of coolant leaks over time.
The current Camaro Z28 utilize a bigger oil coolant/oil assembly than the Corvettes.
While several advantages and disadvantages exist for of each oil cooling approach, it would be very instructive to understand, from an engineering point of view the design advantages, disadvantages, and trade offs that went into the various oil cooling designs.

Way too long. If you want the question answered, keep it simple. He doesn't need a dissertation on oil cooler types by model and year.
Q: From an engineering perspective, what are the advantages and disadvantages of using a radiator with an integrated Engine Oil Cooler (EOC) vs a stand alone EOC?
What oil temp is considered too low for a daily driver such as a Z06?

If you look at some of the comments, we want to know why it has changed some many times, you only list 2.

The dissertation on oil cooler types by model and year is NOT for Tadge, it is to do a level set for all the C5, C6, C7 owners who are not aware of all the oil cooling changes.

Update the question to ask why they would change the approach within the same generation of car, such as the early and late C6 Z06.
...but whatever. Your question. I deal with this type of stuff everyday and short/crisp/to the point gets the attention. Good luck
