    For guys re-using old oil filters....

    As a filter ages it picks up particulates or "loads". This means that as it loads with particulates its efficiency is increasing in removing ever smaller particles. Thus a filter that has been in service for a time is doing a better job of filtering. Change it out with a new filter and the new...

    which oil filter to use?

    Buy the cheapest by the case and save on inflation over time. Oil filters are like fishing lures, they attract more fishermen (and women) than fish. Except I hate Fram, because they rhyme with scam, and the cheap ones are painted S.F. Giants colors. However I buy the most expensive of...

    Why the need for oversized Filters?

    The solution to pollution is dilution. Now I installed a dual remote bypass filter on my cute little GMC Duramax diesel engine. Oil capacity of the sump is 10 quarts, but the two filters take another 2 quarts, so I have a total fill of 12 quarts (see mom I can add), which is exactly the number...

    Fram Ultra / Purolator Pure One

    Amsoil Series 3000 HDD duramax?

    I've been using it for 5 years and 45K miles. I have never had a bad UOA, wear metals are consistently below minimum flagging threshold (iron at 20ppm or below after 21K miles, aluminum between 4 ppm during break-in and 1 ppm afterwards)), soot volume below minimum level ( Is it good oil for...

    Just a question about filters

    I use Fleetguard (Cummins), Baldwin, Racor, CAT, Amsoil, AC Delco, NAPA Gold, Wix, most of which are synthetic or synthetic blend elements. My applications are light trucks, oil and diesel fuel filters. I do not use Fram cardboard or private branded filters that do not have published...

    Amsoil Coolant ?

    I had it installed in my GMC Sierra DuraMax Diesel after a triple flush. The Amsoil coolant meets all ASTM specifications for heavy duty diesel engine use. This engine also has a coolant bypass filter installed. Because any cooling system failure would be expensive, I decided to use the Amsoil...

    GM 75w-90 Synth, As good as other synth gear oils?

    In my case I changed out the factory fill stuff at 15,000 miles in the Sierra 2500HD (DuraMax 4X4) because the dealer refused, saying it was a waste of money. Good thing too, because the OEM stuff looked like the coolant oil from my old DO-All band saw. Refilled with Amsoil 75W-90 Severe Gear in...

    TES-295 Mobil Delvac 1 ATF

    One thing I learned along time ago was not to purchase fluids solely on a cost basis. If a comparable product (all specs match) is available locally, then it's a good deal. I use Amsoil because it's available within 10 miles, and meets every specification for my applications. One thing about...

    Todays Dexcool pic.

    Onion: I share your caution, which is why I research each product before using. The Amsoil coolant meets ASTM D-6210, ASTM D-3306, ASTM D4985-98, and ASTM D 6210-98 specifications for Fully Formulated coolants. The ASTM D-6210, D4985-98 and D6210-98 specifications are for heavy duty diesel...

    Todays Dexcool pic.

    Shortly after purchasing a new 2006 GMC Sierra 2500HD with the DuraMax diesel with factory Dexcool, I installed a coolant bypass filter using the Baldwin B5134 spin-on. Examination of the filter media after 3,000 miles of service revealed residual core casting sand as the primary contaminate...
