So I changed the filter for the 6th time, the sparkles are bubbles lmao, took this filter apart with 1000 miles on it and it was spotless as well, oil pressure is good too according to the autocal, gauge is still 15 psi or so off.
Has anyone tried this Amsoil?
Has anyone tried this Amsoil?
I just put that oil in the 05’ with the built engine on Saturday. Coolant at 190-200* my oil pressure would drop to 17 psi at idle, regular Shell 15-40. With the Amsoil 20-50 it’s holding 19-20 with the same coolant temps.
My brand new built motor drops to 25-28psi hot idle after some WOT beat down runs with Cenpeco Super Race 20w50. At 1500rpm I have 68-70psi oil pressure hot.
at what oil temp though, coolant temp doesnt tell us much as oil temp can swing 30-40* from coolant temp. was your engine setup for that oil as well?
I don't have an oil temp gauge. That being said, that was directly after driving for 30 min in 85F weather then doing 6-7 20mph->100mph WOT pulls at 1700US.
The oil reading was taking directly following the last pull at 208F coolant temp.
Yes, my engine was setup for 20W50.
sadly that still doesn't give much accurate info for temp but I would speculate you to be around the 190-200* mark based on temp. Being set up for the thickness makes all the difference
you guys will find the oil heats up faster and pressure will eventually drop to the same as it was before IF you have not opened up bearing clearances to match the thicker oil.
thicker oil = more resistance, more resistance = more heat, more heat = thinner oil.
just going from 15w-40 dino oil to 5w-40 full synthetic i see a 10* drop in overall HOT oil temp when towing.
And yet by your own reasoning you shouldn't have seen a drop at all. Both xx/40 oils
