In recent threads, some members have said that they're using a different an oil with a different viscosity (0W-30, 10W-30, 10W-40, etc.) than the OEM 5W-30 for Gen1 ST's and 5W20 for Gen 2 ST's.
I've been told by some mechanics that it's not a good idea to use a different viscosity, because that could cause serious harm to seals, bearings, and other internal engine components that were designed to run with the OEM viscosity.
Thoughts/Opinions? Or better yet, can anyone present some hard facts supporting or discounting this recommendation?
