Does anyone know if this is a good oil or how much zinc/phosphorus is in it?
I have a 2003 Subaru WRX (Turbo) and was thinking this might be a good oil for my car. People on my Subaru forum really like Shell Rotella T6 5W-40 but I am worried about the higher levels of Zinc and Phosphorus in it.
Also, people on my forum do not like most energy conserving oils and I see that Edge With Syntec 5W-40 is not energy conserving. Most energy conserving 5W-30's sheer to 5W-20 in the turbocharged WRX.
Maybe Edge with Syntec would be a good alternative to the T6 and be a good oil for my WRX?
