WVO running temperature min/max

Postby vegnomad » Tue Oct 14, 2014 8:34 am

I'm curious about the running temperature range for WVO. I've read you want the oil 150-160 degF that is entering your IP. Is there a minimum? What about a maximum? My truck can see water temp over 212 degF when hauling passes, and I want to know if there are any issues if the WVO gets that hot before entering the IP. Any details you can give about properties of WVO at the min/max range would be interesting to read and appreciated.

The min. depends on the WVO and whether it contains fat or PHO, and is 20-80F where part of it starts to solidify and can clog lines or filters. The extra thickness when cold can also make your pump be too weak causing low pressure and low power. No max. since the hotter the better until about 300F, which your coolant cannot reach. If you have an electric pump trying to pump that hot, they each have their own limits depending on design.
