PYB is a LOT quieter than Castrol

[53' Stude]

So Friday night I decided to change the edge SN black jug 5w20 garbage out of the Focus as it was getting kinda klacky like valve train noisy with it. Following some knowledgeable members advice to try PYB; I put some PYB 5w20 in. After a day of driving over 65 miles total, the valve train noisy ness is GONE. Here on out in my fleet it will be QSGB or PYB


Rant over

PYB 5W-30 would be even quieter....

PYB 10W-30 gets even quieter than that....

Been going through a similar deal with my 3.1 and 5w30 high mileage oils. Mobil Super 5000 HM and Valvoline MaxLife blend were rowdy in the 3.1. While using Pennzoil HM Vehicle and my current fill of Castrol GTX HM, the engine definitely sounds quieter to me. Was really surprised at how Valvoline MaxLife sounded ok at first, but two weeks later the engine was rowdy again. Put the Castrol GTX HM in a week ago today, and the 3.1 is quieter now than any of the above oils I have used. Just hope it stays this way.

I'm pretty sure it's the moly+boron combo that helps

Merk: my ford says to use 5w20; NOT 10w or 5w30. Nice try though hahaha!

Edge is garbage? That sounds outlandish

Did you change the filter at the same time?

After giving this topic a lot of thought, it comes up often, I think the only fair way to judge is toward the end of the OCI. New fresh oil vs. oil that has been in the sump for thousands of miles? That oil is spent. Just a thought.

Oddly enough my Regal likes the thinner oils.

Yep, new filter is tough guard#3614. After two OCI's with EDGE; I'm done with it. Even my "beater/backup car" 98' Cavalier likes some QSGB 5w30 with a WIX filter

Demarpaint: after hearing
And reading the hoop la and praise about Magnatec and edge: sure pulled the wool over my eyes. KCJEEP was right: cannot go wrong with some PYB!

Nobody says anything outlandish around here.

No, never

I think as well the oil was wore out. I know people on here try to stretch the oil to the limit, why I am not sure. Oil is cheap. But new oil v.s old oil and the new always sounds smoother. I have noticed thicker makes quieter too. I wouldn't give Castrol a bad name over it.

Theres a lot of statments that mineral get better, quiet sound and motircycle smoother shifting gears... I had that impression sometimes, but the consenses here is that is just an illusion, impression (the bike gear shifting isnt just impression, nether the noises) ETCG say its flow differently, tribologists discard that flow in difference from molecule unequal sizes ... Since even PAO isnt that uniform in EO by the mixing of # of base oil viscosities, theres no explanation to such enhanced flow of minerals.

Panzerman: each oci was well within the owners manual oci of 7,500. Dunno; it sure left a real bad impression on me. Just my honest, mechanics thought/s


Each run was like 5,000 miles also BTW

 

[53' Stude]

I don't think Castrol gets a bad rap or name; it just did NOT impress me j should have stated.

That same Focus in Australia would have 5W-30 on its oil cap.

 

[Bluestream]

Cant compare a old oil all sheared down to new oil. Just like you cant compare you old worn out tires to the new tires you just installed..

Merk: this is a place called the UNITED STATES OF AMERICA!!!


Bluestream: dunno what that even means

How, with it being the same viscosity at operating temperature as the 5w-30?
