Hi to all.
Today I dropped my TSI Tiguan with some European specialist mechanic down the road for an interim service, I told him to use Penrite 5w30 oil as I have always been.

However when I came back from work to pick up the car I saw an empty Penrite 5w30 Enviro+ GF5 bottle which I know is a different oil to the one VW approves, they do look very similar though.

I brought it up to the mechanic and was told not to worry as they are close enough. So should I worry and do some immediate rectification or just leave as is and no damage will be done to the engine. Please advise.
