With Amsoil even if it's not signature series I trust it more than any other 0w8.
I run Amsoil and my oil change interval is 25k so the answer is it depends.
I only use Amsoil Signature Series in my B58.
I changed to that and really happy with it so far, shifting is butter smooth.
Só compro óleo original na concessionária e da Motorcraft conforme manual.
Based on my own tests, I found the AmsOil to be the best at reducing heat a few degrees. It's not cheap, but it's still cheap insurance, all things considered.
I use Amsoil 20w50 in all 3. You don’t need a different oil for the trans. Amsoil is not cheap but I’ve been using it on my 03 FatBoy since new and have had no problems.
Originally switched to Amsoil for the Noack rating but stayed because it's just good stuff. I now run Amsoil products for all fluids in all vehicles.
I did have a 1982 diesel Jetta go 435,000 miles on oem int. shaft bearings. I had access to a lot of free Amsoil back then....so, that may have helped. However, I think it over-lubed the cylinder walls though. Rings weren't exactly what you would call 'tight.'
I am not hating on Amsoil. I am running their engine oil and ****ing hate it. burned off another quarter of a quart in the last day of driving... ive never had this kind of consumption before and there are no leaks...
