Oil Cooler Spray

tweiss3 · 06-20-2011, 10:03 AM

No, it does drop pretty quickly once i can get it up over 20 mph, but when i sit at a light for over 2 minutes creeping, it scares me. I think im going to mock it up tonight and see how it works. I am going to NYC this summer in late july, and thats really where i am getting scared. I want to atleast be able to make a dent in the oil temp if i were to be stuck below 15 for an hour.

What about running a water/ethanol mix for the cooling fluid?

If that's the case, it sounds like your oil cooler & overall engine cooling system is doing its job as it was designed to. If you're stuck in creeping NYC traffic for hours, adding a water mister to help is not going to be a practical solution since you'll need more water than you can carry. You may be able to drop the temps a few degrees, but the effect won't last long once the tank runs dry.

Better way to keep your oil temps down is to read the traffic, and just shut off your engine whenever you know you're not going to be moving anytime soon.

I also recall reading that racers running synthetic oils in rotaries found they tend to run cooler oil temps than conventional oils. Not to get into the synthetic vs. conventional oil debate, but if you've modded your car to run nothing but premix for apex seal lubrication (i.e., block the OMP & run premix in tank OR use the OMP & Rotary Aviation adapter to run premix via separate tank so you're NOT burning any crankcase oil), switching to a synthetic engine oil might be worth a try.
