I like red line oils, because they have a bit more zddp which is nice for the rockers.
Pros: nice for the rockers
Cons: bad for catalytic converters
On chilly winter mornings (SF Bay Area) the car did not like reverse or first gears. Subsequently switched to Red Line engine oil. More power, better mileage.
Pros: more power, better mileage
Cons: car did not like gears
Vehicle:
Volkswagen Scirocco
Ran Redline 5w40 when it became purely a summer car in ~2013. ... Not seals are leaking, no issues of any form. Car has been Cobb stage 2 91oct tuned (OTS, not pro-tuned) almost 14 years, with a Crawford v2 AOS, Killer B oil pickup + windage tray being the only reliability mods, and it doesn't burn a single molecule of oil.
Pros: no leaks, no issues, no oil consumption
Vehicle:
Subaru
Redline is great, used it for years in a track car.
My STI also used it for a while (0w40), but then switched to Rotella.
Pros: Redline is great
Vehicle:
Subaru

I use Redline, similar quality and price to Amsoil, without the MLM BS.
Pros: similar quality, good price
In my experience of trying many different oils, what I think are the best, as far as the engine running cool and smooth shifting are: 1. Redline 15w50
Pros: engine running cool
Red Line Racing Two Stroke is the best oil I've run. It leaves a good film and smells the nicest.
Pros: good film, smells nice
