K&N vs. HiFlo oil filters
« on: May 03, 2018, 01:56:53 pm »
I'll try to post pics later, but a local motorcycle dealer said that a HiFlo oil filter is the same as a K&N oil filter and that they are both not as good as Wix oil filters.  Bought a HiFlo from him, but I think the K&N is better- it looks to have two times the pleats.  More pleats=more surface are to filter the oil, no?

Been riding this week with the great weather and shifting was getting "sticky" and it had been a year since my last oil change.  I usually change in the spring when riding season gets here.  Shifting smoothness restored!

I try not to go by what the oil filter looks like.

I judge filters by their efficiency rating.
My current favorite is the BOSCH 3323 at 99% efficient.

If I can't get that, then the SuperTech ST7317 for filtering out harmful contaminants.

I used Fram 7317 Tough Guard filters on my C-10's SPOOFAK adaptor for many years with zero issues.

Unless your engine/transmission is grinding itself to bits any oil filter will be fine at the intervals most oil change schedules are designed for. I've dissected a fair number of oil and diesel fuel filters and have found nothing of importance in any, regardless of quality (perceived or known).
Worry less.

Great info.  I will admit having heard Fram are not very good (bobistheoilguy.com) as far as filters go, good to hear that may be inaccurate.

I've only had one oil filter show considerable 'defect' in 35 years.  I use the oil filter they have in stock at autozone.
No... I don't remember the brand name, it lasts 5k miles every time.... win.  I do use Hi-flo air filters... and they work fine.  ;D

Been riding this week with the great weather and shifting was getting "sticky" and it had been a year since my last oil change.  I usually change in the spring when riding season gets here.  Shifting smoothness restored!

If you only change your oil once a year, I suggest you change it right before you put it away for the winter, that way your not letting it sit for long period's of time with old acidic oil.  The last ride of the year for me is to top of the gas, then I change the oil when I get home, fire it up to let the new oil get all through the engine and put it to bed for the winter.

Be careful with K&N - I had the top nut fail a few years ago on my VFR800 and it was not pretty. Lots of discussion on other forums about this flaw.

Thank you all again for the recommendations, I'll change in the winter, in my area there are usually a few days each month where it's nice enough to ride even through winter- though not very many so I'll change it earlier like recommended.  The K&N's I use are cartridge style since I lack a SPOOFAK on my C10.
