    Thumbs up Oils; 300 tdi back ground info; Penrite Tech team

    Just for your interest , I'm sharing some advice given to me by the penrite technical team, to some questions I asked about lube oils.

    cheers simmo


    Hi Guys at penrite, I'm a long term customer of your fine oils, In my 1995 Land Rover defender 300 TDI, with R380 transmission and LT-230 transfer case, I'm using Progear 70-75 full synthetic in my gearbox , and trans gear semi synthetic in my transfer case (75-90) and diffs,and semi synthetic 15-50 in my diesel engine. I'm interested in the viscosity/ temperature curves for the gearbox oils. my transfer case is running between 60 -70 degrees and my gearbox is running at 75 degrees, engine sump is 75 degrees, diffs 45-55 degrees. ( ambient was about 25 degrees), temperatures at cruising speed on the motorway, I'm considering gearbox and transfer case coolers, because I expect the temperatures will raise up in summer when the ambient is higher. I'm trying to find what is about the optimum temperature to run the gearboxes, so the oil still has acceptable viscosity.

    I appreciate your advice. thanks for your support. brgds simmo.

    response from Penrite technical team.

    When the temperature of the oil reaches 100C then any moisture should be driven off very easily- not a bad thing. This is perhaps a good target temperature.
    You will not need cooling by the looks of things ?our oils will easily cope as this is what they?re designed for.

    In an oil?s rating --eg SAE 75W-90-- that second figure is derived from a check of the oil?s viscosity at 100C.

    If oil is frequently up to 130C you can start to run into trouble, but this is only likely in the engine.

    Calling Rick130 ... your inbox is full!

    I was finally placing an order today for 20L of Motul Gear 300 based on advice Rick130 provided some time back via PM and was asked if I wanted

    MOTUL GEAR 300 LS 75W-90 - Motul
    or
    MOTUL GEAR 300 75W-90 - Motul

    I don't remember seeing 2 variants of this oil last time I looked into it - but maybe I missed it.

    I have 2 Defender 130's, one rear diff has a Detroit TrueTrac in it. I'm hoping to use 1 oil across the driveline of both vehicles.

    Do I get the LS version? Will that be OK to use across the rest of the driveline?

    (Edit: I just re-read Rick130's original mesa=sage where he advises "With the TraTrac or ATB you need a fluid without LSD additives, which is where Gear 300 is great, it's optimised for good synchro performance in a gearbox/transaxle so works well with torque biasing diffs" and https://www.eaton.com/au/en-gb/products/differentials-traction-control/aftermarket-differentials/detroit-truetrac-faqs.html confirms friction modifiers should not be used - so I assume I need the MOTUL GEAR 300 75W-90 - Motul version ie. No LS)
