I can attest to this, blew five D-series myself. Some had ported oil pumps. Some were reving above stock revlimit. One was abused unknown to me had damaged main bearings and I was pushing it too hard during a street tune. My first semi built block blew with the old German Castrol 0w30 from 1999...

All it takes is a little education for the public. That sales guy having a lack of understanding, is one of the problems with society.
I take it, you will never see Belgium Castrol 0w30 in that one store ever again. I would think Castrol Corporate Sales Rep, should be concerned about this...
^^^He did this on my direction and ran a high end synthetic.^^^ For a while he had a bad t-stat that could have let too much moisture stay in the oil and brake down a paper element sooner.
I haven't been impressed with paper end caps not adhearing to the media through the oci on low end filters.
In neglected oci's with metal end caps, I've seen the glue unbond from the metal endcaps.
My coworker went a year oci with a baldwin cellulose media oil filter, and the element falls...
For an example the GT-1® High Performance Synthetic Blend Motor Oil with Liquid Titanium® HTHS viscosity for their 5w30 is 3.1 vs 3.0 for their 10w30 in the same line up.
Isn't the issue that they are using thin conventional oil that's going to evaporate under normal operating conditions?
I used to think like that guy in the shop until I learned about volatility.
As for the Bmw's I don't know, because I didn't think they would be putting 5w20 conventional oil...
I was thinking of changing out my K&N cone filters for this Amsoil type. The nano fiber flows better than paper, and supposed to filter better than cotton gauze.
You have tbn depletion with an engine when sitting in storage from the moisture contamination in the ambient air. Oil with some mileage on it, will have contamination you don't want sitting in the engine in long term storage unless the oil contains anti rust additives such as classic hot rod oil...
This Magnetic looks very similar to something Castrol was selling back in the early 2000's. I called up the lady in Jersey and she told me they used esters in the additives only but the base oil was fully mineral/conventional oil. Maybe they dropped that oil, after a spec upgrade.
Looking at...
Can you run a longer/larger filter that won't bypass as easily?
Have you cut the filter's to see if it's "making metal?"
I get the Belgium Castrol 0w30 when it's on sale, the 5 qt deals and stock up.
I did some checking and the extreme characteristics of the EFO make it look like very good base stock quality.
I feel the EFM would be more like EDGE and M1 in material.
I've been a little off topic, but thanks to Pablo, I can see the advantages.
Dang, I just stocked up on two oil changes worth of the Castrol Edge 0w40. The price of the Amsoil EFO seems substantially higher than Edge, and M1 0w40 line when you get the Jug deals.
What about the quality of EFO being twice as goood? I'm not convinced that it is, after coming here.
I'm...
I got my daily driver VW 1.8t cheap because of an oil related failure. The previous owner neglected the oil changes, used greed bottle quaker state with wax and didn't maintain the oil level. Eventually most of the oil evaporated out and left black sludge peaces on everything clogging the pick...
