Has anyone bought Engine Oil from Tesco?

I've bought the Helix Ultra due to the cheap promo price from Tesco the other day and thinking if it's from Tesco it should be original and with a good price also.

However, at the mechanic, after unscrewing the top cover, I realized the silver seal has been broken

It looks like someone has tampered with it

Now after 500kms driving in that oil in the morning the rev goes up to 1.7k and engine feels like it's misfiring.

Will probably change out this oil very soon.

So how to check whether seal inside broken or not? Have to unscrew the top cover?

New packaging with natural gas technology!


How to bring to them when the mechanic has already drained off all the old oil and the only option is use that oil and not use the mechanic's oil

it looks to me that yes it has been tampered with.

However, I noticed something fishy... when I goto shell website they did show that the new bottle designs have a code which can be smsed to verify the authenticity of the bottle, but this bottle from Tesco no such code.

Misfiring might not be caused by the oil, just hoping that the oil is real.

I've tried using fake oil in my old car before and the engine oil just disappears, lost of power and bad mileage - 350kms per full tank when averaging out 450kms before and after changing out fake oil

Have you opened it yet?

Is the seal tampered with?

Is there a code in front to scan/verify for authenticity?

Thanks.
