    Brand new silverado metal shavings

    Bottom line, oil change costs $30-$40 bucks. $30 bucks compared to a $40-50K rig is a no brainer. Those that prefer to take the risk, you keep running the oil. Those of you who prefer to take a proactive approach, change the oil/filter. Install a known filter product. Auto Mfg's do not install...

    Tytan - Hyd oil vs. gear oil

    Ramblejam, I appreciate your response. The confusion still lies with the data plate information and the referenced lube in the manual, see above. The data plate references 90W - for tranny & running gears - equivalent Vg @ 40C is 150-220 cTs, not 55vg as Mobilith 424 - stated on website. It may...

    Tytan - Hyd oil vs. gear oil

    I am posting this for a friend. The data plate on his tractor states: Engine oil 15-40W, Tranny - 90W, Running gears 90W, Hyd 10W or AW46. The question, they believe the hydraulic and running gear share the same reservoir so which lube oil would he use in the hydraulics?? I am more involved on...

    thinner grease for wheel bearings a hypothetical

    IMO, I would have a hard time believing drag/resistance from wheel brg grease causes loss of fuel efficiency, doesn't grease separate? Currently my boat trailer has oil bath brg's. I do believe oil bath brg's will extend the useful life of the brg vs. greased brg's. Grease retains particulate...

    DTE 26 vs Mobil Gear 600 XP 68

    DTE 26 & MG 600 XP both have EP/anti wear additives. However, it is not too often you see a gearbox in the industry that has a AGMA of 2 (68 Vg), must be a very light load application. Unsure if you are switching fluids in the gearbox from Syn to MO or not. If so adequate purge is required and...

    Oil cleanliness

    I know this is an old thread but the patch (04/19/14) looks like rust particulate, Babbitt particulate and other ferrous mat'l. Did you notice a bathtub ring in the reservoir before you swabbed the unit? If this is a turbine, you may want to have a UC (Ultra centrifuge) test performed to...

    '93 GMC Sierra 1500 5spd, Tranny fluid

    Regarding a '93 GMC Sierra 1500 w/305 c.i.d. 5 spd tranny, anyone know of the fluid specifications? Seems GMC changed fluid recommendation during this year but I cannot confirm which would be best for the tranny.
