Everyone with oil temp issues

Chupacabra · 04-15-2009, 02:20 PM

i managed to hit almost 240 on a 92F day here in florida, 3,000mi.

Then i tired the AC trick, and it brought the temp back down to 210.

so when in doubt just turn the ac on.

The AC trick? Turning on your AC should make the car run hotter if anything. Did you mean you turned on the heater full blast with the windows rolled down?

I did a post about this before.
My so-in- law had a Saturn, that out of the blue, would over heat. Turn on the A/C and the temp would go down!

Seems counter-intuitive, but if it works...

The A/C condenser is definitely going to dump more heat in the area of your radiator. The only thing I can image that's at work here, is perhaps when the car is "overheated" only 1 of the two fans is running up front, and the other one only turns on when the A/C is turned on.

That's a good possibility!

Im even toying with the idea of buying someone on here some motul and seeing if they notice a difference. (someone with the high temps). BTW mobil one is just quality crude oil. class III with a little class IV. yeah, i was dissapointed too. Any takers?

There's already a couple of oil threads and lots of heated (but friendly) debate on the subject. I'm going Motul 300V on my next change, and at least one other person had talked about it too (semtex?):

Yep. I've got 3 cans of Motul at the ready when it's time for my next oil change. I'm also the guy who suggested Water Wetter earlier in this thread. Glad it's apparently helping. I added Water Wetter in the day after I bought my car and haven't seen my oil temp go past 240. Mind you, I haven't tracked it either, but I have driven it quite hard for extended periods.

Anything else and your risking mixing something that may break down what your cooling system needs. And there are other variables no one thinks about (except me) like electrolysis (might be misspelled). How is this chemical effect your head gasket? how does it affect the conductivity of the coolant which eats head gaskets? what about lubrication? does it build up in your motor in the hot spots that you cant see?? Trust me.... I have seen plenty of crazy things. the best thing to do is to change it approx every 30,000. Gasoline, oil, coolant, brake fluid, all automotive chemicals have a shelf life just like milk.

Water is the best liquid thermal conductor - period. The other stuff is just to prevent the water from eating your engine parts and prevent it freezing like you said.

Our cars come with a 50/50 mix so they aren't as efficient as they could be. Improving the thermal conductivity of the coolant by altering the ratio should have a definite improvement on the ability for the coolant to absorb heat from the oil, hence lowering oil temperatures. It's not enough for the track but it might be enough for the SoCal people to survive summer.

My understanding is that our oil is water-cooled on this car. Hence, if you improve your water-cooling ability, you by extension improve the oil cooling. As for your list of concerns, have you done any research into this particular product to substantiate them? Because if you have, please do tell. Water Wetter is made by Red Line. Here's a link to their Water Wetter page. There's a product data sheet link at the bottom too. It lists all these chemicals that I'm sure will make more sense to you than me.

The water wetter works, but it should ideally be added during a flush when you add pure distilled water with the appropriate amount of wetter.

Thanks Dad I'll be sure to try that next time I'm on the race track. lol jk

My car doesn't seem to get over 220 even with spirited driving. It's about 75 degrees out here, guess I got lucky.

Water Wetter is a super favorite among the sportbike crowd.

I don't want to rain on the parade, but I do want to offer a warning. Nissan has an ever increasing rate of warranty denials. I don't think it is outside the realm of possibility that Nissan would deny a warranty claim, for drivetrain components, if the coolant mixture had been altered. I'm not saying it will happen, or is happening, just that it might happen.

Very good point Joey - I'd worry about that too.
