I have a Toyota Corolla. Since I bought it brand new a few years ago, I always have gotten synthetic oil on the oil changes. I have always used the Toyota dealership.
When I got the oil changed yesterday, they accidentally used the normal oil instead of the synthetic oil. I found this out by look at the itemized receipt.
The advisor said that I can bring the car in and they will switch out the oil and filter for the synthetic oil and new filter.
The problem is... how will I know they will do that? There is no way to verify since the oil is already clean looking on the dipstick. They could easily just let my car sit for 20 minutes and give it back to me.
I really want synthetic oil in my car. It's my investment and it gives me a peace of mind.
What should I do in this situation?
