Would love some feedback on this one. I have heared good and bad. I have gone over 30K and think it would be a good time. Some of the questions I have are:
1) How many of the cars that were exsperenceing oil starvation used synthic oil. (that auto-cross thing)
2)What kind should I use
3)Does the change in molecular structure have any advers effect on the cylnder walls (I'm streching), the viscosity is different. 4)can you ever go back to regular oil
5)Is anyone crazy enough to go 6k with out a change
Thankyou for dealing with my inexsperence 
I just changed my oil to Mobil 1 5W 30 Synthetic and noticed a quiter engine.
Also, my car didn't heat up as fast as it normally did with regular oil.
