In the 6.7 Powerstroke SP/ LV fluid, recommended by Ford, are synthetic oils. ATF is much thinner and similar to the consistency of hydraulic fluid. Very similar to engine oil most of the above applies with only some differences. Since coolant and oil temperatures go hand and hand, you can see benefits to oil longevity from the SPE low temp, high flow thermostat. You should also consider running synthetic. So, if you see high temperatures frequently tightening up your maintenance schedule would be smart. If proper maintenance isn't done and oil life is degraded its ability to withstand temperatures will be much worse. If too much moisture is in the oil that can also affect its ability to do its job. Making sure that during operation oil temps reach around 178 ☏ to burn off condensation that builds up over time. For example, if your oil temp sensor is reading 220 ☏ and it is located in or near the pan, the oil in the turbo center section will be 15 to 20 degrees hotter due to the localized heat from exhaust temperature being so close to it. ![]() This matters because of local heat differences. Looking at this from a real world perspective there are a few things to also consider: These are very basic temperature figures based on general lab testing. Most CK4 17+ synthetic grade oils will withstand much higher temps, some manufacturers actually claim close to 300 ☏. Īt 250 ☏ the oil begins to degrade very quickly causing many issues. Mineral based max temps should be kept under 250 ☏. Mineral based oils, for example Rotella T4 and similar CJ4 rated oils, will carry a lower maximum temperature for operation in comparison to a full synthetic oil. This is going to make all the difference so you know when your oil breaks down and when it’s additives and lubricity are no longer functioning.

Also, it’s recommended to maintenance and check your coolant with a hydrometer every few months to make sure the freeze point ratio is correct. ![]() That means knowing your thermostat temperatures are key. Therefore, saying coolant temp should be around 200 ☏ in this application does not work so well.Īlthough coolant temps are regulated by the thermostat and operate accordingly, knowing your base temperatures are key to keeping them in check. Primary stock is around 195 ☏ whereas the secondary system is around 100 ☏. The 6.7 Powerstroke, as an example, has primary and secondary cooling systems which operate at completely different temperature ranges. Being that factory ratings are not always the best for longevity or real world use there are many things that have to be taken into consideration when deciding fluid operating ranges for an engine or transmission. The age old question, “How hot is ok?” comes up many times in conversations, tech calls, forums, and groups.
