I can’t trust anything from someone who can’t spell a word as simple as Amsoil properly.
It looks like they loved Amsoil in the first link listed. We’ve run their engine oil in plenty of customer’s cars who sent it in for oil analysis and Amsoil always tested better than whatever they were using before. I’ve never had any issues with their engine or gear oils so I trust them.
I’d love to see a non synthetic 75w90 test…
