I can understand you don't want to run M1 products but when they are some of the better oils out there they have to come up in the conversation, lol.Any idea how well that JT-8 performs in a shared sump V twin? I have been contemplating putting some in my '99 Victory. Rotella is one of my favorite oils but it just doesn't cut it in a shared sump, shift quality sucks after 500 miles. I refuse to run Mobil 1 products in anything so don't bother to mention.
I ran JT8 in my shared sump ZRX1200 for a shorter OCI, worked well, nice additive package.
