Amsoil Synthetic

Hmm..

I'm thinking I might just stick with Amsoils 5W-40 for year round use.

Hey Diesel Nut, once again thanks for the excellent info. When I,m ready to do the bypass I'll give you a call.

Not a problem guys. I am here to share what I know and to learn from you guys as well!

[straycat]

hahaha no lack of learning on this site. I learn something new every day.

According to Amsoil Tech, the pour point for their 15w-40 is -43*C, that seems cold enough for me.

My Dodge holds 11 qts. I would consider anything over that large. 7-8 qts seems to be about the break even point from my figuring and anything under that the synthetic actually costs more to run.

I personally have a mistrust of K&N filters (esp. their air filters). I stick to either Amsoil or Napa oil filters (or some of their spin off lines).

Anybody directly compared these 2 systems?
What do you think?

Hey DocB, I have no hands on experience with them, But what I have found out is that the powerstroke does not like the double bypass system, causes a lowering of the oil pressure leading to more wear than is acceptable. you are better of with the single bypass filter remotely mounted with your flow through filter in the original position. If you go through the thread you will see a lot of discussion on it, and other things as well. good luck

Also, besides the oil pressure drop is the noise. The whine the motor puts out is enough to drive you insane. The single does not cause these noises because the main flow of oil goes through its normal channels, and does not cause harmonics in the hoses.

As I understand it, both these systems are single bypass.
I was just wondering which was better, and if anybody else had
done some research into it and had come up with a reckoning.
I am also contemplating putting a bypass oil filter on my Jeep Libery(diesel)
and was hoping to use both the same systems for the PSD and CRD.
Same filter element=life alot easier.
