Hi everyone, long time lurker - first time poster.
I'm changing the oil on my 2005 Subaru Legacy GT. I bought the car last November with ~65k miles. It's stage 2 with 300whp on an OEM turbo. Owner was running M1 0w-50 racing oil, I replaced it in late November with RP 5w-30 cause there was an great deal on it at Pep Boys. I've heard of people running German Castrol in their turbo Subarus so I was wondering if the same concept could apply to the Amsoil version?
From what I've heard SAPS is essentially a measure of the protection of the emission systems on the car based on the metallic anti-wear additives. My car has no catalytic converters so I figured I could run full SAPS to get the maximum add pack possible. I saw that Amsoil recently came out with a full SAPS 5w-40 and wanted give it a try. I finally broke down and got a case of 12 with 2 Amsoil filters instead of the 5w-30 Signature Series. (The 12 quarts and 2 filters were cheaper than just the 12 pack of the SS alone!!)
Does anybody see possible problems running this oil in a modified non-Euro car, granted there is no emission system on it? I will be getting a pre OA and post OA at about 3500 miles since this oil is so new to the market. I'm interested to get your guys opinion...
