TT thanks for explaining the reasons for the oil consmption but i don't agree with your theory on the American based tuners not having tuned files that include lean burn mode, unless you have hard evidence that they don't then I don't think this advice is relevant at all
I noticed you carefully didn't mention any actual names
Erm - it is a well-known and simple matter of fact. All North American FSI engines have the lean burn mode disabled. Look it up in any of the online official Self Study Guides.
The reason why American motors have lean burn disabled - well they dont have the 'ultra low sulphur' unleaded petrols like we do in the UK and Europe. Again, it is well known that North American unleaded petrols have a high sulphur content. Now, under true lean burn conditions, the combustion temperatures reach such high levels, that nasty things start happening with any sulphur content - which is exactly why VAG FSI engines have their lean burn or 'stratified' mode disabled. The same happened when Mitsubishi developed their GDI engine - they where completely unable to use it it the US and Canada, becuase Mitsubishi were not willing to disable their own lean burn mode.
And as for 'naming' and shaming certain tuning companies - well this has been discussed at length - and when one particular tuning company tried to come out with some BS that they were able to 'get hold of UK specific ECUs' - well, they were shown up for the frauds that they were!
