honestly untill i swapped motors... i used rotella t6 5w40 all year around. i only switched because of one sentence someone i respect and trust told me.
"ya sure rotella is a great oil, but its manufactured as a diesel oil, and find me a diesel that revs over 5k"
so i switched to motul for my 8k revving ej207 at the recommendation of my tuner. mind you i know a few people with 207's and still running rotella t6 and they have no complaints.
subaru recommends 5w30 because they assume everyone abides by the law and does the speed limit and doesnt give it more than 50% throttle...basically manufacturers think we all drive like grannies. the 40 weight that everyone uses is because we beat on our cars. its a boosted awd street machine... we drive them like so, and you will want the thicker/heavier oil to withstand the heat and the poundings.
my wifes honda pilot says 5w20 on the cap and i couldnt ever see anyone ever putting oil that thin into a car that isnt some sort of purpose built engine that isnt in a daily driver. her dad is a mechanic so she gets free oil changes but where he works doesnt have rotella on tap or else i would probably just use that aswell. its cheap and good stuff.
