Safe oil temp reading at sandwich plate?
Tried doing as much research as I could before posting a thread, but researching oil temps has my head spinning looking for an answer. I'm curious if anyone can has any insight into what kind of temps I should be seeing, safe temp and max temp, at the filter sandwich plate. I couldn't find any info regarding how much temps vary between reading at the sandwich plate (oil cooled via coolant, but pressurized) vs reading temps from the pan (not pressurized).
I attended a drift event 2 weeks ago, and I was seeing temps around 240 after a few hard runs, after which I did a cool down lap just to be safe. Normal driving around town, temp sits around 200-210 or so, no oil cooler besides the stock one. I'm using rotella T6. Thanks. |

I wouldn't go above 240.

Oil isn't a gas. Pressurizing it isn't going to make it hotter.
The oil at the sandwich plate goes there from the oil pump before it goes to the rest of the engine. Your bearings will be seeing the temperature that the sandwich plate sees, lower if it passes through a thermostat/cooler of some sort afterwards. The oil pan represents the temperature of the oil after it's passed through the engine. That oil doesn't do anything other than sit around and wait to be sucked into the oil pump.

Depends entirely on what oil you are using. Some oil is perfectly fine at 275-280*F. Some oil I wouldn't push beyond 220*F.

My feeling on oil is that:
-if you're worried about oil temps (which you should be at 240+F), do something about it- run an oil cooler with a fan. In my experience, getting ideal positioning if you already have an FMIC and huge radiator is really hard and the fan makes quite a difference. A small fan with 200-300 cfm is plenty. A water sprayer hooked up to a thermostat (instead of a fan on the oil cooler) would probably also work if you are just doing short but extremely punishing runs. -an oil temperature alarm at 260 is actually a really good idea, but not for anything relating to oil temperature. It's a backup for when your coolant goes missing (ie, from a huge hole in radiator/hose/etc) and the coolant temp sensor doesn't have any coolant touching it anymore. Your car will overheat VERY quickly and the only sign will be elevated oil temperatures. -if you run an oil cooler, run a thermostat, especially if you street drive the car at all. It's the difference between having room temperature oil for 2 hours vs 180F oil in 2 minutes. -run a good oil anyway, rotella T6 seems to be the consensus. I have run mobil 1 15W50 in the past. -keep an eye on hoses and belts for wear and leaks because swapping out a slightly frayed hose is cheaper than swapping out an engine. You should always route hoses to avoid wear and damage, but shit happens. |
