This is not what I was asking. My car shuddered around for a week until I realized they put in something different. When I brought it back they told me I was SOL and that no manager was available. The shuddering stopped after a few days and I haven't thought of it until the accident. Is this the correct information to ask for a meaningful response?

How did you realize they put in something different?

 

I awoke from my favorite hot afternoon nap spot, glanced up at the stickers on the windshield and everything printed on that piece of rubber was incorrect.

Is this Kenshin XI?? It's gotta be.....

 

Putting in the wrong viscosity of oil would not make your car Shudder..

 

An ASE Mazda tech said it could put strain on the lubrication system, in turn putting stress on the engine as a whole. I know those guys can be wrong too, but it doesn't matter now. I found out that the factory radiator cap oring blew out from the jolt. Huge weight lifted, some of you understand the feeling.

it would help if you stated what weight oil was put in

 

Nope.

 

I lost it right there XD

Is English your first language? You seem to have difficulty conveying relatively simple concepts.

Unless gear oil or ATF was substituted, motor oil has NOTHING to do with anything you have described in your posts.

You have an old rotary engine...it could act up or die completely at any time, for any reason, and have nothing to do with anyone who touches it today or any repair or maintenance done today.
