HD-Because of the .05

 

HD Filter

 

Seriously?? Motorcraft FL1A is what I used on all of my 5.0 Mustangs.

 

WIX # 51348 for the filter - black and is about $5.00 bucks

Royal Purple 20/50 for engine and primary

Royal Purple 75/90 for the tranny.

I spent alot of time on slow escorts, about 20-30 mph in TEXAS HEAT. I have 35,000 miles on my bike and it runs great. I have used the HD oil and the bike would get hot alot easier and hit the cool down safety slow idle, whatever its called. It dont do trhat with the Royal Purple oil. thats just my .2 cents

 

Has anyone tested for the duration of filter bypass with the different micron ratings?

If anyone has a harley oil cooler, you could install the "T" fitting (Part # 126165-07) in line and hook up an oil pressure guage in place of the temp guage. Once installed, you could determine if you spent more time bypassing the filter (no filtration) with a 5 micron as opposed to a 30 micron filter.

The point is (I think) , If you send oil through an engine several times while the engine is bypassed (5 micron with no filtration) as opposed to sending the oil several times while the engine is not bypassed (30 micron with filtration) which filter is protecting your engine the best? I hope you answered 30 micron.

I think everyone agrees that most wear occurs at start up. Unfortunately, this is also when most filter bypassing occurs.

The correct answer to "What Brand Oil Filter" may just be two brands. One for start up and one for operating at normal temp. But it don't end there....you still have to find the filter that bypasses at the pressure that the Harley engineers intended for your model or you could find yourself not filtering nothing.

Of course this is all just speculation because I really don't know anything about it.

 

I use the harley filter but I would use any filter with a bypass valve.

 

Bosch 3330, used on my Evo for 30k miles now, available, affordable, and the labels peel off...

I saw a listing in my Wally-world for the fram filter but they didn't have it. Went to about 6 different auto parts places who didn't have it and finally the last one found a Wix number and said he could have it by noon tommorrow. Costs about $10 down here in D/FW, Texas. Mine is chrome so I don't know how this is gonna work out till I pick it up. Now my dumb question is where is the drain on a 98 Lowrider? Just bought the bike 1.5 months ago and being my first H.D., I don't know a whole lot about them. I already put a little over 2000 miles on it so I figure it was time to change it. Thanks.

 

The guarantee that you are getting a 10 micron filter designed to bypass at the correct pressure in the event of a clog.

Would you bet your motor on someone else?

Ifanother brand clogs, will it go into bypass??
