Engines heat up to operating condition burn cleaner and produce less e. At the other extreme you would always like to see a maximum oil temperature of 240 F or below.

For most mass market cars 6065 degrees Celsius is where the engine really starts to come into its own.
. Likewise what is normal coolant temperature for a car. However it takes much longer for oil to come up to temperature than coolant. At sits between 195 degrees and 220.
Up to 120 degrees C 250 degrees F is OK if a decent oil is used but getting a little warm. Some engine builders believe oil should be kept around 80 degrees C 175 degrees F to keep things safe. Another thing to consider when watching your engine coolant temperature is.
My LS2 actually sounds better once the oil warms to 200 but most of what I read states that you need to get the oil over 225 once in a while to boil out moisture. I will say this average oil temperature is 212F the boiling point of water. Generally speaking optimum sump temperature is 80-100C.
Older pre 1995 automobiles used a thermostat set to open at 180 or less. The acceptable range for an engine to run at sits between 195 degrees and 220 degrees Fahrenheit. I see anything from 180 at night after 12 miles to 240 in the day after 12 miles it must have been hot.
Injection power units are designed for a higher temperature 95-114 degrees and the pressure of antifreeze in the cooling system can rise to three atmospheres. If the transmission is slipping or you are pushing the vehicle hard the temperature could rise above 240 degrees. If the oil is 10 cSt at 212F then at 104F 40C it thickens up to 100 cSt and at 32F 0C to 250cSt and so on.
Forged 402 Stroker 856 RWHP750 RWTQ Paxton Super Charger 20 PSI ECS Big Blower Cam American Racing Headers 373 rear Corsa Extreme Exhaust Methanol Injection Pfadt Coil Over. Sump temperatures up to 120C are ok albeit with increased oil oxidation. At around 9095 degrees Celsius the radiator fan begins to operate to provide further cooling.
15-20 minutes from cold start would be a ball park figure. The acceptable range for an engine to run. Thats actually fairly normal for slow city driving on a hot day.
This means that with a sump temperature of 245 some of the oil will be at 295 at some point and that is too high. As a general rule of thumb after the car is warmed up oil tends to be a few degrees warmer than the coolant usually 10-15 degrees Fahrenheit. I dont drive more than 15 miles at a time because the oil just gets too hot.
Their findings demonstrated that the temperature inside a car can increase by 40 degrees Fahrenheit on average over the. This assumes a person is running a 5050 mix of antifreeze and water. This gets increasingly worse as the temperatures drop and at the low temperature limit for a particular oil when it gets really cold it can be over 1000 times thicker than at operating temperature.
You want to see a minimum stable oil temperature of 200 to 212 F to drive off any fuel or water from cylinder blow-by present in the oil. A 245 oil sump temperature is an indication of incorrect tuning or engine installation. However with every 20-degree drop your transmission remains better protected.
Oil temp is typically not an issue but coolant temp should stay below 230-235 degrees. Scholars at the Stanford University School of Medicine performed a study in which they investigated the rate at which the interior temperature of a parked car increased during sunny days of temperatures between 72 and 96 degrees Fahrenheit. Optimum performance for both economy and power is achieved at temperatures around 100-107 degrees C 210-225 degrees F.
As I mentioned the oil temp is there because of the turbos since the turbos make the engine oil temp run higher than a non-turbo car. Engine oil temperature for optimal lubrication - unthrottled. Oil warm up is slow-much slower than coolant.
It can also be damaged by high temperatures which can reach 275 degrees. The best thing for your engine would be that it was never turned off you simply kept driving day and night. Experts advise car owners to keep engine oil between 230 and 265 degrees.
The engine is designed to run at 212F at all external temperatures. Studies show that as the oil goes through the engine it will at some point usually see about 50 higher temperature than the oil sump temperature. Newer automobiles use thermostats designed to open at 195 degrees or more.
If there is a gasoline carburetor engine in the car then the optimum temperature for it is in the range from 85 to 97 degrees. In all cases less than 100C 212F will cause water buildup in the crankcase. For most cars the normal operating engine temperature is in a range of 195 to 220 degrees Fahrenheit though most dashboard temperature gauges dont show an.
The operating temperature is controlled by the thermostat. Normal Oil Temperature In A Car Engine And Water Temperature by kingschild123 m. For full synthetic motor oil maximum can exceed 300 degrees.
When these engines first came out there were some owners who experience elevated oil temps and BMW made some changes to make sure the temp stays within a safe operating range. Click to see full answer. My oil temperatures have been ridiculous.
222pm On Jul 30 2013. This will likely be somewhere in the 160 to 190 degree range based on what your drive. Any more driving than that and the engine compartment starts to broil and smoke sizzles off of everything.
Ideally the fluid temperature in the automatic transmission would range from 170 to 225 degrees Fahrenheit. As others have mentioned the normal temperature depends on the car and the type of fuel used. For non-synthetic motor oil the traditional approach is to try to hold oil temperatures between 110C and 125 degrees 230-260F.
When you start your car in the morning most of us are wise enough to not romp on the car until the coolant gauge is up to operating temperature. Answer 1 of 17. Normal conditions will see an average cars oil temperature of 250 degrees.
