Can someone enlighten me as to what exactly is the 505.01 spec, and/or advise weather or not it is a good idea (or moot) to use it in a supercharged gasoline powered application? I am not an oil enthusiast at all so a lot of the jargon thrown around in the threads I've already read don't add up to much...
The reason I ask - today I was given, (that's right, free) several quarts of Castrol TXT 505 01 5w40 API SJ...
So, what is TXT 505.01 and what makes it "Special Edition for pump-nozzle engines** (nowhere on the bottle's documentation or lables do I see what the ** indicates...)
To elaborate on the engine may use it in - a Honda SOHC 1.6 4 cylinder (D16A6), built, supercharged ~200whp, 165tq. No intercooler/aftercooler, so that = hot boost and subsequently elevated combustion temps. Since break in, I have used only Mobil 1. The car doesn't see much annual mileage so oil changes are infrequent. The M1 that I need to drain is definately pre-reformulation.
If this is not the place to ask, I apologize. I just jumped on the newest 505.01 thread in hopes for a quick education/reply.
Thanks!
