[Solved] I have a Lexus ES 330 2004 with 210,000 miles on it. At 200,000 miles I put synthetic oil in it for the first time ever (that I know of, I am the third owner). Since I learned you don't advise making the change to synthetic in an old car like mine...

I have a Lexus ES 330 2004 with 210,000 miles on it. At 200,000 miles I put synthetic oil in it for the first time ever (that I know of, I am the third owner). Since I learned you don't advise making the change to synthetic in an old car like mine, should I switch back to conventional or stay with the synthetic?

If it hasn't been running synthetic up to now, I would swap back. Synthetic oils have a lot of additives that older seals and gaskets do not like, so you tend to start seeing oil leaks when running synthetic on an older, higher mileage motor.
