    Less start up noise (easy to hear in a cold diesel ) and generally smoother through the rev range.
    Sounds like placebo, but I have had the car for 6 years and drive it every day.

    The E3 Clubby has lived on a diet of Mobil 1 since brand new, and I was able to get it at $49/5 litres so stocked up. I still have 3 or 4 changes worth at home and the car did 3000km last year. Then with the recent work on the engine, I was suggested that Penrite Racing 10 would be a better option (10w/40), so it will change to that. Better oil pressure when hot, but it maybe the change of oil pump, rather than the thicker oil.

    The SV6 is my daily sh1tter, so I am not so fussed between switching to whatever mainstream brand is on special from time to time. I stocked up on Nulon 5w/30 synthetic about 12 months ago, so still have about 5 oil changes worth at home. Add the no longer needed Mobil 1 and I have a few years worth of oil without having to think about it in storage.

    My mates used to call me the "Sheik of <Home Suburb>" as I always had stock of great oils that I bought cheap.

    I have been using the Penrite Racing 10w40 in my stock LS1 for the last 3 years and about 5,000km's, and I can 100% confirm that it maintains better oil pressure when hot
    I have consistent oil pressure during the dry season when the temperature is in the high teens to low 20's, and also during the extreme heat of the wet season when the temp is in the high 30's and the humidity is hovering close to 100%
    My oil pressure is over 40 psi at idle on the gauge when cold at first start up, and just under 40psi at operating temp

    For what it's worth and to use it as a comparison:
    I was previously using Penrite HPR5 5w40, as this was Penrite's recommendation at the time I purchased the vehicle
    During the dry season it was fine, but during the wet season the oil pressure at idle when hot used to drop down to 20 psi
