So I changed my oil in the P6B,and with advice I put miller's 20w50 classic oil,not sure what oil was in it before hand but she was smooth,since putting the 20w50 in my oil pressure is alot higher,when I accelerate the oil pressure goes up to about 70psi and a tiny bit of tapping which was never there before,should I dump the oil and use miller's classic 10w40 semi synthetic,any advice guys
