Re: Oil drama in GT 2.0 JTS!!
There's a very famous article which is google-able all over the net which describes a very detailed trial run by the US equivalent of the AA (or Which? I can't recall) that basically tested a range of different oils through a brutal long term test on NY Taxi cabs.
They stripped engines down, measured all the tolerances, built them again and stuck them in identical cabs which were then used for a long time and a lot miles each on different oils ranging from cheap as chips to top-of-the-range.
At the end, when they stripped them all down again, there wasn't a single measurable difference in wear rates on any of the cars.
The results were used to get shot of a lot of the comparative mud slinging in oil advertising which was becoming ludicrous.
Basically - your car engine needs oil. Clean oil. Changed regularly and kept to level. End of.
