I personally did the test and I went there properly expecting it to make no difference whatsoever. To be completely honest I was pissed about having to 'waste my day' for a test I thought pointless.

I was utterly amazed to see how it performed. We ran both a Focus ST and an Astra VXR on the day and both saw significant gains.

Yes, Millers paid for the test as it was sold as an 'Advertorial' but we drew up a contract where we stated that we would print the results even if they demonstrated the oil made no difference at all. Millers were happy with that as they were confident in their product. The test was conducted honestly and fairly, and the fact that it was paid for made no difference to the results whatsoever.

If I had to find fault with the test it's that I'd ideally have liked to have run the cars again, but on some other 'performance oil', as we tested it against Halfords Oil as a control, and a different brand of oil 'may' have also performed well.
