Just out of interest, found the current specifications for maximum amounts of additives to achieve API ratings. P is phosphorus, Zn is zinc, and B is boron. Each figure is total parts per million of additives. These can also be roughly expressed in percentages by multiplying by .0001 (1301 PPM = .13 percent, 994 PPM = .099 percent) API P Zn B SJ 1301 1280 151 CI-4 1150 1374 83 SL 994 1182 133 CJ-4 819 1014 26 SM 770 939 127 The following is comparison with Penrite HPR 30 and their Classic Attachment: Capture.JPG So the Classic is sitting at 1670ppm which is getting up there, but safely under the 2000. not a lot over the HPR30 though. Haven't compared prices. I'm meeting with an old mate that is in the automotive oil business tomorrow, be interesting to see what he thinks - and what he sells. |
