NEED HELP, On Oil! Quick Question! 5W30 or 10W30 and synthetics???
 

Hey guys I bought my 2003 G 6MT used with 32,000 miles on the clock and it looks like the guy before me used 5W30. Not sure if he ran synthetics or not. Anyways, I live in Washington State, and I wanna I have Royal Purple Syntetic Oil in the garage, its 5W30 and I also have some 10W30, now its a full synthetic, and I guess my main questions are...

-Is it OK to switch to a FULL Syntetic even tho there are 33,000 Miles on the car
-Should I use full Synthetic 5w30 or 10w30

THANKS FOR THE HELP!!!

There's no problem switching to a full synth. I think most people on here use 5w30, myself included.
