synthotic oil

I used to swear by Mobil 1. Then I put it in My '01 Jetta. I had to keep adding oil about a quart every few hundred miles. I called Mobil Tech Support and the guy on the phone was a total douche. I just wanted advice as to maybe wait a few oil changes and see if the consumption slowed down. He just kept on arguing that there must be something wrong with my engine. He hammered me about what oil did I use before trying to say that changing brands or weights ruined my engine. He was a Total Butt hole. I pulled it out and put in Castrol Syntec because I really wanted to run full synthetic. It didn't hold on to the Syntec either. I switched back to conventional oil and it doesn't use a drop.
My Jetta had about 100,000 miles when I made the attempt to switch and I was always told not to try Synthetic on an older engine. Now I believe.
In your case I believe Synthetic should be a great choice But I have blacklisted Mobil due to horrible way the Representative handled the situation. I knew my Engine was fine because it never used a drop of oil before and I changed it every 3,000 miles with Quality oil. All my other engines get Synthetic Amsoil including my Motorcycle and Lawn Mowers. None of them use oil at all.
