Just bought the car with little over 40k miles The oil gauge usually at idle sits around 50 but when i floor it or am gong up hill it goes all the way up to 80 is this normal i thought it was cause i need an oil change cause it said 12% when i got the car but no change in the way the gauge acts since the oil change. and also if you can help the cars real loud as if the ac fans on or whatever but it never goes off im sure thats not normal any ideas on whats causing it?
The noise you are hearing might be coming from the center air vents. There was a fix back in 2008 which called for pulling the vents out and adding something to quiet them down. I don't really remember exactly but it was done to my 2008. Try a search for "a/c vent or dash noise" It may take a little bit of work narrowing down the search but I know it's there.
As far as your oil gauge, I have nothing to offer.
