Hey guys,
I have been running 10w30 synthetic for a couple of years now. Today i went to get my oil changed and they fucked up and put regular 10w30. I was in a rush so i didn't notice until i checked the receipt after i got to work...
I usually fill up my car every month or so since it has a small leak and have 10w30 synthetic at home to do so.
My question is, what should I do since they put regular oil this time?
Should I just buy some regular 10w30 and fill it up with that or can I use the synthetic i got at home?
On the other hand, should I just go back and try to have them just redo it with synthetic all over? Is there anything wrong with having run synthetic for so long and all of a sudden go to regular?
My car has 160,000 miles on her btw.
