Hey guys i just got my twin turbo lq4 running. After about a half hour of driving the car the oil temp is reading 175 degrees F. It was also 90 degrees outside. Im wondering if this is too cold for the oil? Everything i have read says it should be around 200 plus degrees. The coolant temp is right around 190 degrees.
I have a 6 qt pan with a griffin 12x12 oil cooler with a fan. It is full flow (no thermostat) on sandwich adapter at the stock location for the oil filter. The cooler holds approx 1.25 extra quarts as well. I am running 5w40 rotella full synthetic oil. The computer i am running is a holley dominator with a holley coolant temp sensor for reading the temp.
thanks for the help.

Where is your sensor located?

Sensor is located in the feed to the cooler. I Looked up a few inline themostats, they are all set to open at 180 degrees. So i might be fine im right there with my temps right now.

As long as your oil temps don't go north of 230-240 for very long, you'll be ok. I wouldn't consider it screaming hot until the 280 range. My road race care lives at around 240 oil and 230 coolant and that's driving it HARD for 30-45 minutes (using eBay oil cooler and DeWitt's radiator). Once, my floorboard got so hot from the exhaust, the sole of my shoe melted. Floorboard temp was 220 after I got out and the seat temp was 150. Time to wrap my exhaust! lol

If your running full synthetic oil, I would not be remotely alarmed at 240*F oil. 250*F + is where I would be looking for a cooler.

Synthetics are just better full range, so cooler to hot they are more consistent and handle heat without breaking down. At 190*F with synthetic I wouldn't be worried about how the oil is performing but more about just making sure the water evaporates.
