2.0T (170) Engine Roughness - Timbo66
I've been having some issues with the harshness of my car's engine between 3000 & 3700 RPM. It normally only happens when the car is warm & I am accelerating. When first reported to my local dealer, they said it was a lifter problem & replaced the hydraulic lifters under warranty. However, this didn't resolve the issue. They then told me it was a characteristic of that engine. I referred it to another dealer who said that the car had the wrong oil in it, though it was correct as per the handbook. They said that Vauxhall now recommended the 5/20 for the Turbo engines. However, this change has been no difference either. Anyone else had a problem like this?

5W/20? That's a new one. There isn't a 5W/20 Vx oil available. I think every new Vx runs on their 5W/30. That said a minor change in oil viscosity is very unlikely to cause the problem.
