Good on ya for using the proper oil and trusting your instincts.

There is 2 ways to look at this.

you could let it go and either you or another tech will eventually be in the same situation later on.

or you can speak to the actual service manager about how you felt bullied and belittled and for advice


the fact is, the mechanic is in charge of making a vehicle safe, cutting corners can potentially be harmful.

now, im not saying that this situation is potentially fatal for the car. but what if this "acting manager" has had a history of making wrong decisions but goes on his "power trip" , as you say, and other techs thought the same way as to just let it go. if thats the case then who knows how many cars this guy has screwed over in his "20 years of experience".

Mindbomber, if he had a legitimate reason for his decision, wouldn't it be proper to actually educate the apprentice? and on top of that, he asked the service adviser first, then the customer agreed to use sythetic. the acting service manager was not the one helping the customer. OP was just doing his job and taking care of the customer.

on top of that, conventional oil should be changed every 5,000km, synthetic every 10,000km. so that means if conventional oil was used in the 370z (depending on how the owner drives) and 10,000km later gets an oil change(they have a sign that comes up saying an oil change is due), wouldn't the oil be dirty and burnt? couldn't that be potentially harmful to the engine? or lets say he is constantly going to this dealership and they were using regular oil all this time but the "oil change due" sign comes up every 10,00km. its always best to use what is recommended just to avoid any potential situations.
