The amount of hyperbole in this thread is drowning out rational discourse. And I haven’t seen one single argument (logical or otherwise) for why we should ignore the guidance from Ineos shown here and substitute someone else’s untested, unproven “I’ve always done it this way” procedure.
I accord manufacturers a presumption of publishing good faith, well-researched and economically advantageous service specifications (for both the manufacturer and consumer). So the bar for ignoring them is pretty high.
Glen, nobody is making you ignore anything. Do it how you like.
But, there are already reports from multiple people across the globe including myself who have witnessed or been told directly that some if not most Ineos dealers fill to spill. That's not hyperbole, that's data.
The fact that the SST. Number is X'd out and dealers/service agents have had to cobble their own "tool" to measure the fluid suggest that Ineos doesn't seem to care enough or is simply ignoring the practices going on at their service centers.
And finally, do you really trust Ineos that much? Their engineers have botched so many things and continue to produce vehicles in new model years with the same issues. We have drive shafts melting down, diffs blowing up, diffs locking up randomly at high speed, seals leaking, roofs leaking, windows leaking, trucks filling up with water, software from hell etc etc. these are all things that were largely avoidable.
