Rating 4.0

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

Rating 5.0

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
