I'm currently running RedLine 75W90NS. I think initially, you'll be very impressed with the results.
However, it seems, after a couple thousand miles....the shininess wears off and I start grinding when trying to get into first, again. I also grind going into fourth when I hurry it. I have to temper my enthusiasm going into fourth. But, I'm guessing this is one of those case-by-case basis things. Soooo, YMMV
My roommate is shocked that I would allow these condition to go on like this. So, I've been researching alternatives.
I think I'm going to spring for some of the Neo gear oli stuff, but it's PRICEY! Maybe the aforementioned Royal Purple might be the call. Maybe I'll try both and report back.
