    Pump in Grease or Oil?

    I know the most common packing is to have pump in grease. I have heard that oil should be used instead of the grease for performance gains. Just wondering if anyone has experience with this? Thanks.

    I first used amzoil gear lube and it turned black...just like fercho said it would....I now use the fercho method of half and half synthetic grease and synthetic gear lube mixed together to form a runny paste....been working so far.

    I do it like Fercho recomends also Amsoil synthetic grease and gear lube mix until it's a runny paste no problems so far.

    Redline D4.

    40 hours on my XLT just checked it....still brite red and smelled fresh...changed it since it was open.

    10 hours on my 1500 gpr...just opened it up to try a different bearing...same as the XLT.

    two others are using redline D4 with mor ehours then 40...both with no issues.

    good stuff.

    Redline D4 is designed fro auto and manual gearboxes. gear boxes use roller type bearing just like our pumps.

    http://www.redlineoil.com/products_g...8&categoryID=8

    "Our most popular and versatile ATF, D4 is suitable for use where Dexron III, Dexron II, or Mercon fluids are recommended. D4 ATF is a fully-synthetic product designed to satisfy the improved low-temperature requirements which will be in the new Dexron IV specification, and the improved shear-stability requirements which will be part of the new Mercon specifications.

    D4 ATF also provides a GL-4 level of gear protection, making it a superior product for transmissions and transaxles like the Corvette's T-56. The balanced frictional characteristics provide smooth and consistent shifts for extended drain intervals. The superior stability compared to petroleum ATFs allows high-temperature operation without varnishing valves and clutches which leads to transmission failure. It’s stability allows high-temperature operation without varnishing valves and clutches. Also provides improved shifting in cold weather. "

    Royal Purple Synfilm 60. Been using it for 5 years running.

    I am sure there are several "options" people use.

    I use this method also. I believe it is the marine graded Amsoil synthetic Gear oil and grease, this will displace water

    Amsoil it is! Which specific products are you using (Name, part numbers, etc.)? I need to order some more Interceptor so I might as well get this at the same time!
