Finally got my car back, took them over 2 days to replace the cam gaskets which caused an oil leak damaging one of my coils. On the invoice when I picked up the car it said the added 2 quarts of oil, which they didn't mention to me. I asked what oil they used and they responded by saying my car can use either regular or synthetic but I had regular so thats what they put in. I had to correct him, I used royal purple synthetic with my last oil change and now they just mixed in 2qt of non-synthetic. So is there anything I need to worry about? I've also heard that once you start using synthetic you shouldn't go back to non-synthetic. Also, do you think they should have to pay to drain and replace my car's oil with the synthetic brand I was already using?

 

If you have your receipts for the syn oil, you'll be in a better position to have them do the change..or if the dipstick can show the "right color", it should also help.
Good luck.

 

It's a wive's tale that you can't mix the two, what do you think a "Synthetic Blend" is?

It will not hurt a thing and no they should not drain your oil and replace it with the synthetic, it is just a top off. It's no different then taking your car to a dealer and they "top off all fluids."

 

its no problem, but why didnt you tell them you have synthetic before hand

 

Ryan, did you have any luck scrounging for your missing pieces?
