I bought an oil filter from AutoZone before my current oil change. I remove the old filter and notice that the new filter hole size is much smaller than the old one (7/8" vs 1-1/4"). I tried to put it on, but doing so would require some force to get it installed. So, I put the old one back on instead. I order new 2 ones from RockAuto and they arrived the other day. I put the Mann filter on and it's a perfect fit. The other filter I ordered (Mahle) also had the smaller hole.
Have others noticed this disparity? If using the smaller hole filter type, is it OK to force it on?
Thanks.
