Cant find filter replacement for WIX or Fram HP 6 !!!!!!

AMSOIL HELP ????????????????

If I am running 540s, 700 hp. Change the oil and filter once per year, 20-25 hours. Do you still recommend Amsoil or Mobil 1? Or, should I keep using the Wix Racing filter?

Planning on moving from racing Valvoline 40 to Mobil v-twin oil. If this makes a diffenence on filters? Thanks.

604 inch fords, naturally aspirated.

Swapping out HP6s at 10 hours and complete oil change at 20.

I am not criticizing your break down of filters at all. Just from my perspective, I want flow #1, Big stuff filtered #2, Little stuff #3.

Here is what I have been finding out....

25% of folks use something like a Wix Racing 1060R/Fram Racing (especially on bigger engines).

25% go with the Mercury HP Racing

25% go with a filter that is basically a synthetic fiber 10 micron filter

25% go with an "off the shelf filter"...paper filter ...

I won't freshen for approximately 200 hours. Or, until I see a loss of power. I have about 50 hours on them now.

So you are saying stay with the Wix Racing Filter? Using in conjunction with Valvoline VR1 currently.

Wix Racing & V-Twin if you can spend the $$.

New filter...no info but the add.

Hydrocruiser, what do you recommend on the 700sci? I was told the Wix 57003R was the OEM for Mercury. They are $120 shipped for a case of 6 vs. $65 ea. from the dealer.

Mercury also recommends Kendall GT1 racing 20w50 in the 700sci and specifically says not to run a synthetic. Is the Kendall oil any good and why not run a snythetic?

Sounds like you have the right filter. If I had that engine I would compare oil pressures with the WixR and Amsoil Eao....if there was not a pressure drop I would personally use the EaO. That's just me... Kendall GT-1 Racing is a great oil.

Not sure why Merc does not use synthetics as many big engine builders do.

If the concern is that there is a myth? fact? that synthetics do not protect metal after
shutdown and corrosion may occur...motorcycle oils are extremely corrosion resistant.

It may be why many like M-1 V-Twin?

I have used the wix 57003R / with Kendall GT1 20w50 on my 2009 600 sci for 75hrs and no problems , I change oil every 15 hrs for cheap insurance .
