Is there an issue going back to regular/ non-FM fluid? At 1200 mile service, dealer put in the regular/ non-FM fluid. At 30k mile service, the same dealer put in the fm fluid, but I never had an issue with noise. I did not know they put the fm fluid until the work was done and I saw the work invoice. I told them about it after but it was too late. They said it is the only fluid they carried/ dealer excuse. I will be doing my 60k mile service soon. Thanks in advance for the response.
I asked this same question in the DIY: Differential Fluid Change thread in the DIY section almost a week ago with no response. Link below. I'm hoping more foot traffic in the general section will give me a response.
