The reason the PSI dropped is because the 5w-30 flows better. All you are going to do with the heavy oil is blow seals and gaskets. The higher PSI is because it's not flowing nearly as well. A PSI that high is similar to someone having a blockage. Sorry but you are just plain stupid for running such a thick oil and I'm sure your gas milage is hurting to prove it! Higher PSI is bad, but so is 0!

The problem with America is stupidity.
I'm not saying there should be a capital punishment
for stupidity, but why don't we just take the safety
labels off of everything and let the problem solve itself?
