Yeah our engine runs pretty hot and Ester's are very shear resistant... Which means it maintains it viscosity at high temperatures...
On the filters, from another post I made earlier;
From what I understand the Puro has a finer filter but this comes at the expense of flow rate (though still within SEA standards). Now the bypass pressure on the Puro is also somewhat higher then the K&N.
So allthough it filters better just from a filter performance point of view and therefore does good in tests, I'm wondering how good it is for our engines, especially when you drive them under high load for a longer time.
I wasn't able to find the exact specs for the two different filters and I don't know if this is correct, but this is what I found for similar filters:
Purolator PureOne PL34631
* Average largest pore size: 42 µm
* Smallest pore size: 10 µm
* 30W 70F Oil flow @ 10psi: 5.3 oz per minute
K&N 3002
* Average largest pore size: 63 µm
* Smallest pore size: 27 µm
* 30W 70F Oil flow @ 10psi: 14.7 oz per minute
So there I would go with either one based on how you drive;
- during break in I would go with a Puro,
- then after if you drive it hard a lot I would use a high flowing K&N
- if you drive more modest I would go with a Puro for filtering more.
These are of course all just my opinions...
