Today the "check engine" light came on and I made a phone call to get it checked. He told me to come by at lunchtime and he would take a look. He hooked it up to the computer and found that I had no oil, despite the fact that I had stupidly taken my car in for an oil change at Oil Changers in Novato where clearly no oil was changed! Mike filled it up with a quart and I made an appointment for next week for a checkup. Again when I tried to pay him, he would not let me give him a cent - "my money is no good there!" Mike Oliver has true integrity and knows how to look after his customers - great guy! – Margz D (5 star review found on Yelp)
