Dealership put in regular oil instead of synthetic in my 130,000 mile engine
 

I thought I had established I wanted synthetic oil, so when I got home and saw the window sticker said my next oil change was due in 3,000 miles I was suspicious. Sure enough, they threw regular in it. Looking at my invoice they charged the regular oil price.

It's a 2004, the engine has 130,000 miles, I've used synthetic since I bought it at 40,000 miles. Take it back or just run it?

It's fine, I run full conventional with 110k.

Just run it. You may want to think about high mileage oil when it's time to get your oil changed again.

Phone them up if you're not happy! If you specified synthetic and the can see you always have run it maybe they'll change it no charge. They should if you were clear in your specifications - IMO It's more about you being happy than the oil me thinks

I'd take it back and tell them to drain it, flush it and put what you asked for in it regardless of mileage. Its recommended in the handbook, its a sports car not some old clunker, I'd get back there and get it sorted.

The owners manual recommends conventional oil, does it not? Pretty sure I read that.

Wrong Oil?
 

You want the job done right...sometimes you have to do it yourself.

AmsOil 100% Signature Synthetic 5w30

Take it back, have it drained and swapped.


Better yet, get a refund and do it yourself. If they do it, they will hold the car for an hour and not do it.

This makes me want to put a GoPro in the cabin and go back just to see if they even pop the hood.

They also screwed up my radiator install: https://my350z.com/forum/engine-and-...no-heater.html

I've always had excellent luck at the dealership, not sure what hex I woke up with that day.
