My boyfriend accidentally filled my diesel car with regular gas late on a Saturday night when we were planning on leaving Sunday morning. After researching, we realized we were screwed and would probably have to stay until Monday and pay $500+ to get it drained and fixed properly. Luckily for us, we found Villa! They were the only mechanic open on Sundays in SLO, worked on it all day and had it done by closing. The guy at the front was friendly (sorry, forgot his name) and helped ensure the car was done in the same day. It ended up being $350 which was cheaper than the other estimates we found. Thank you Villa!!
