This is just plain not true...I couldn't find the actual bulletin referenced here, but I have no reason to doubt this content from an Astra forum.
"Bulletin just been released by Vauxhall advising that for Turbocharged Direct Injection Engines there is a certain risk for Stochastic Pre Ignition (SPI). This SPI causes strong pressure peaks in the combustion chamber which may harm the piston ring lands.
Fault:
Sporadic metallic noise from combustion chamber, sometimes with short loss of power. Occasionally fault code 'P0300 Engine Misfire' is stored but not all the time. Engine Light might not even come on when power loss suffered. This may be the source of the engine splutter / short loss of power people are experiencing in 1.4 Turbo.
Affected Models:
Amongst the affected models are the two versions of the 1.4 Turbo in the Astra K (B14XFL/T RPO code LE1 and LE2). I have the 150ps 1.4 Turbo Astra K which is RPO code LE2.
Resolution:
Vauxhall/Opel/GM have developed a new engine Oil - Dexos 1, Generation 2 to reduce the risk of this fault happening. This new Oil is essential to be used for Astra K 1.4 Turbo. However up until this point only Dexos 2 has been available. The new Oil will be released in the final week of April 2017. The part number is: 95599877 which comes in a 5 litre container, larger sizes will be available at a later date. Model Year 2017 cars are shipped with the new oil in already. "
I have seen other references on this site about d1G2 being specified in Europe...supposedly, dexos2 will be updated with an LSPI test at some point.
I did a terrible job quoting this post...I only meant to discuss the second sentence I have bolded now, I certainly did not mean to say that dexos2 will definitely be a problem in a DIT engine.
Only wanted to show that GM is recommending d1G2 for some Euro vehicles.
My bad!!!
