Ok going to change out the oil tomorrow. I have on hand; PYB in 5-30 SM/ SN, Maxlife blend in 10-30 SN/SM and Mobile 1 full synth. HM in 10-30 in SL (older version). Gonna run a cheap Super Tech oil filter since I got a bunch of them on sale a while back at Walmart for like a buck each. Who wants what in this ole' girl? Not that it really matters but...Let me know.
