180* is when oil is warm enough for WOT, if WOT is prudent.

REMEMBER - give time to the trans & diff to warm up as well. They also need heat.

I wait until I have 180F oil temp. Oil Viscosity changes with temperature, that's why I wait.

With Mobil 1 5W-30, I don't think it is a huge deal. But I also wait, at least until the water warms up. I feel that it is more of a thermal expansion issue than a motor oil viscosity issue, since the oil behaves like a lower weight oil when cold.

I usually wait until I get out of the neighborhood.

The Nascar guys warm it to 160 before starting the pace laps. By the time the race starts I'm sure they are around 210 or more.

Not my taste but looks well done.

CodyC6

Me too. But since my house is the first in the neighborhood I may not wait as long as others.

167 - I heard that pilots don't use full throttle until 167. Also, it is just over the half way temp on my HUD.

The problem with cold oil is the viscosity is much higher than normal and you will notice the oil PRESSURE is much higher than normal. The higher pressure builds up because the higher viscosity oil will not flow through the oil journals as it should for proper lubrication. Running the engine hard under that circumstance could be starving essential rotating parts of the engine and cause undue wear. If you will look at both the oil pressure reading and the oil temperature reading, you will find a number where the oil pressure finally reaches your normal pressure readings. At that point your oil temperature reading will be your "good to go" temperature reading. When that occurs, the engine can be used to it's full abilities with all the proper locations receiving the designed oil pressure.

I wait until I shift it from reverse to 1st after I am done backing out of my driveway. Then WOT down the street I go.

Bought my Vette from a retired pilot who knows a thing or two about WOT and said he waited until 150 degrees before getting on it and that's what I do....

I've always felt that If you’re able to drive a corvette every day of the week practically year round .... then you can afford the luxury of 15 minutes or more of normal driving to let the oil get up to 190 before you get on it.

In some small way letting it warm up to a higher temp will allow it to go to 150 - 250K and more more reliably before needing a major rebuild. Even when driven .... briskly.

I admit it rarely goes below 30 here all winter but if it’s -10 below and it will take you 45 minutes or more to warm up the engine not to mention the tires…. why would you want to stomp on it anyway?

ProfessorDeath

About 180 is pretty safe.

How can you own a Corvette and never use wide-open throttle- at least for a few seconds?

I was standing next to a real C6R(18" away) and the car had been sitting for some 3 hours. Even before that, it had only been moved from the transporter. The engine was at ambient temp of 85 degrees.

The guy got in, started the car, and immediately started blipping the throttle to 5-6000 RPM. The engine didn't blow up.

My ears were ringing for several days after that, as I was standing next to the exhaust outlet.

"I wait for my oil temp to reach XXX before going full throttle...."


I don't have XXX's - I have little numbers on my oil temp gauge

You live in AZ and I live in MO. There are far more areas in the US that has weather like in Missouri, then like in Arizona. The last cruise for lunch I made in my Z06 was a couple of weeks ago. Drove 40 miles at 40-65 MPH with some slowing down for traffic( one hour drive time). Ambient was 50 degrees and my oil temp got up to 136 degrees. Shut off the car for 30 minutes and then started it and drove 70 miles at speeds of 45-65(1.5 hours drive time). Ambient was now at 70 degrees and my oil temp was now at 145 degrees. Then hit heavy traffic for 10 miles, driving at 30-45 MPH and sitting at 3 or 4 traffic lights(30 minutes drive time).. When I reached the restaurant, I had to wait, idling, for some 4-5 minutes for the traffic light to allow me to make a left turn. Ambient was now 71 degrees and my oil temp was at 156 degrees. Total drive time of 3 hours to get my oil temp up to 156 degrees..

The only way I can get my oil temp up to 180 degrees with a 70 degree ambient, is to drive in first gear at 5000 RPM for 10 minutes.
I don't do that.

Driving hard(WOT) at Talladega with 90-95 degree ambient, I only see the oil temp hit 200 degrees.

JoesC5

looks like you didn't check off the RPO box that allows you to show the oil temp in XXX. But, it is a very expensive option.
