In my juiced up SG & a bone stock RKC, I've used either Amsoil or Mobil One in the engines.....I can't see any difference. Change at 2.5 - 3K.
Redline syn primary lube & Redline syn transmission lube.
The Redline makes for noticably smoother shifting with less clunk, period, end of story.
Change the primary & transmission at 5K; safe intervals.
