I basically don't like when shops assume I don't know anything about cars because I take my car to a shop to get an oil change rather than doing it myself. I was a loyal Hontech customer until recently I was told I needed a whole new oil pan for my Honda because they could not work with the aftermarket oil plug that was on the car. It had a oil plug used by places like JiffyLube. It has an opening in the center of the oil plug for them to attach a vacuum to suck out the oil. Well the plastic plug in the center had broken off and because of that Hontech could not change the oil and recommended to install a whole new oilpan...I opted out and the next day went to Autozone, bought a new oil plug for $2.50, and changed the oil myself. Saved myself a few hundred dollars. I'm no longer taking my vehicles to Hontech and looking for a new mechanic....
