I don't disagree at all that a company that doesn't have a product for a specific application, and tells a prospective customer that they don't, is doing the right thing.
I also don't disagre with what Frank said about Mobil's answer - and I'm not questioning or doubting that he asked them the question.
What information do we have? At an undetermined time, Frank asked Mobil a question about (presumably) a VW transaxle application. An unknown person, presumably someone from Mobil Tech services (probably a level-one customer service rep with anywhere from 1 to 90 days experience) said they didn't have a product for VW transaxles.
In addition, we know from Frank that some transmission companies use composite synchros. Is VW using new synchros or traditional materials? Since this is a thread about VW transmission fluids - and one of the issues is synchro compatibility - what is the value of the composite synchro comment?
Based on my experience as a tech services rep, and in dealing with various levels of reps in the computer, networking, and lube industry, the situation as it's currently outlined doesn't have a lot of value until we know the approximate timeframe of the request, the application Frank was looking for a lube solution for, and the Mobil gear lube product lineup at the time of the question. And if we had a 'why' for the non-recommendation, all the better.
jombl - you've made it clear in another thread that you are "not qualified to interpet or debate oil on it's technical merits" - why did you walk into a lube tech thread if not to simply to disrupt a discussion? I agree with your statement that "Muddying the waters serves no useful purpose." So I ask again - why are you in this thread?
