I've put 20K on it since I switched over, 7K since I did my magnum head swap, and the only seal I had changed was my cam seal, cam sensor seal, and head gasket because I swapped the sensors over.
I switched my 86 S-10 over to synthetic at 75K miles when it was 18 years old. A slight leak developed at the pan that might have already been there.
I switched back and forth from synthetic to conventional oil (depending on how poor I was at the time) in my 05 neon. Still, no leaks.
My 95 NYG neon. It had a different motor from an unknown year, and unknown miles. I put synthetic in it, it didn't leak.
Want more?
My mother's 97 Dodge Intrepid, and my father's 94 Hyundai Sonata. We used standard oil in them until 2000. At that point, my father switched all the cars at the time to synthetic. They never leaked.
My brother's minivan has had 3-4 oil changes since 2004, it's a 2001. I wouldn't switch it to synthetic if it was mine.
So, what you're saying is........synthetic oil will cause a leak.Ghost Neon wrote:Leak:racer12306 wrote: I guess that bolded bit doesn't imply that synthetic causes leaks.

You bet your sweet ass it does not. Old seals used with regular engine oil tend to experience leaks when switched to synthetic. Experienced this on 4 of my own cars and many others from friends and friends of friends. Seriously. It has to leak past something, in order to cause a leak. That something is the weak point, like you in this thread.
Come on man, you're smarter than this, I know it. Don't try to argue like Skill does, it makes you look retarded.
