my oil pressure guage has been acting funny for several months, since i put synthetic oil in. but lately it seems broken. it reads all the way past 60 when im driving normal and sometimes at idle it reads around 45 or so. what gives? and also my voltage reads close to 15 when normal power for a charged system is 13.2. any ideas?

Your sender is most then likely messed up and needs to be replaced. It's a common problem with our cars.. heh
