Air Con. ON = Lower Oil Temp.?

YamahaR6 · 06-09-2010, 08:11 AM

I realized when air con. is turned on, the oil temp is lower than usual.

Could it be because when air con. is on, the coolant fan is on as well?

Anyone here notice? Or I am hallucinating?

I think it's cooler because you feel cooler.

Like people talk about global warming on the hottest days of summer. 'Man, it's really getting hot on planet earth...'

I don't feel the oil temp being cooler; the oil gauge is telling me it's cooler.

I drive w ac on all the time....if anything, ac makes the engine run HOTTER.

Here's a theory:

AC cooling off the engine?? - Fuel Economy, Hypermiling, EcoModding News and Forum - EcoModder.com

The dual fan theory may be closer to right. Most of these vehicles equipped with a/c will have a dual fan setup with one dedicated to the condenser. So it is likely that the second fan would and may be cooling the car a little more.

Call me crazy, but I noticed lower oil temps with the AC on sitting in traffic....

Off topic, let me know when you get tired of the F.I exhaust.

So I am not hallucinating.

What does the hammer and nail mean?
