TOYOTA SIENNA GAS PROBLEM

2001 Toyota Sienna • 100,000 miles

At 95000 I started using blended oil, now at 100000 I have gaskets leaking quite a bit, is this because of the blended oil or just a coincidence? If I go back to the regular oil do you think my leaks will slow down? Should I just get the gaskets replaced and continue to use blended, will it help the car?

Synthetic oils years ago had issue with gaskets but today, not an issue. Get the repair done and keep doing what you are doing.
