I just repowered to the 525. I bought a Fram HP4 filter and Valvoline "max life" synthetic blend 20w-50 oil. Will I be OK? Motor had a Wix filter when I got it but I couldn't find one of those. TIA.

Should be fine.

This should help you make a more informed decision.

Thanks guys. I put the Fram on but haven't run the engine yet. I'll find the Wix and lose the Fram. Frequent oil changes will be done. This wasn't a cheap re-power!

This was a very interesting and informative study.The only problem is it was done 10 years ago.A lot of things may have changed since then for better and worst. It would be interesting to see the same test done now.

I used the Fram HP4 for six years with excellent results on 500 EFI's.

I run the NAPA Gold series on mine. Heard from a few non Fram likers so I to the careful approach.

Use the HP and you will be fine.....Wix better, maybe; but 8 years on blower motors and never a failure with fram hp. I like the radio active orange.
