would like your opinions on the ' golden amercan 4', 20w/ 50 synthetic/petroleum motor oil and the 'golden american' synthetic gear oil. I have been using redline products but finding it hard to come buy. Thanks
I don't know "beans" about oils but the thing that comes to mind is that in all the tests, comparisons, etc I've read over the years on various oils, Spectro never rated very well in anybodys test. That alone would steer me in another direction.
My 2 cents, RR
