Just some thoughts here on this thread.
The poster complaining about "merciless criticism", is the exact same poster that mercilessly complains, ie., whines about Purolator now being German owned by Bosch. Don't believe it, search just about any oil filter thread that mentions Purolator/Pure One and even some that don't, and you will see that as fact. Forget that the Pure One is made in the US. So, IMO there's very little credibilty regarding Purolator or Pure Ones, because of constant merciless Purolator ownership
axe grinding!
As far as the textured coating, I like it because it make s installation a breeze. I have a stash with two Purolator made filters, the Advance Total Grip and the new gold Pure One, never had any issues. Early in production, there were some complaints about the coating. One BITOG (dermarpaint) poster emailed or called Puro with his complaint, was quickly sent replacements and told that the texture formula was changed.
In addition, Purolator customer service has been praised here many times for their quick and knowledgeable response on a variety of questions about the P1, including beta rates, media type and efficiency questions.
Back to the texture, like I said I've never had an issue BUT I always check inside the box no matter what brand/type filter it is. Probably a good practice, especially if you are prone to whining after the fact. That said,
no one is perfect, if you're not satisfied contact Purolator. If you're not satisfied after that, then very simply,
don't buy a Pure One. However, if you buy a Bosch Premium, you're still buying a Pure One made by Puro without the texture. The Bosch are more expensive around here and don't have offers on Amazon or Advance $10 coupons.
Lastly, if you can't stand your unused "cheap" inefficient tin can Pure Ones, I'll be more than happy to give them a thorough inspection and use in real conditions. Then I'll report back on the results. Just PM to send them to me. Thanks!
Carry on.
