So I finally did an oil change today. The oil filter was a nightmare, since the car wasn't up on a hoist. For those of you who own an Integra GSi, will understand.

I ended using Nulon Semi Synthetic 10W30, hopefully there's a noticeable improvement from Magnatec 10W40. Used a Ryco Z79A for the oil filter.

The oil filter that was used by the mechanic when I got it serviced, was not equivalent to the Z79A, but it was interchangable Z547. Now the Ryco website, recommends the Z79A. So I'm a little bit concerned.

After googling both oil filters, I came across another filter brand called Micro Filters, their website claims that their Z547 is ok for the Integra (doesn't specify what year) http://microautofilters.com.au/f547.html.

Micro Filter Z79A = http://microautofilters.com.au/F79.html

I haven't had oil pressure issues, so I'm not sure whether this is a problem or not.

Should I be worried?
