I have a 99 Corolla, automatic with 115000km and just bought it from the dealer about 5 months ago. Took it in for an oil change last month and wasn't thinking straight and told the guy to put synthetic in instead of the regular 10w30. My old car had synthetic and now this car does! I didn't want to put synthetic in and didn't realize till after what happened! How can I change back to regular oil without ruining the engine? Flush it out? Is it worth keeping synthetic in?
have the same problem?
