    GTX Magnatec Is Back

    From member Shannow: "Years ago, I was at a dinner, and sitting next to one of the Castrol chemists who was involved in the early testing of the magnatec. He stated categorically tht it works. Their test protocol on the test engines was * baseline (Mobil 1 actually). * flushing oil. * test oil...

    GTX Magnatec Is Back

    I agree. I really liked the original semi-synthetic Magnatec, I too found it super smooth and quite. I often caught myself glancing down when stopped at a red light, to check my engine was still running (it was). Nothing else did that. They then brought out the full synthetic Magnatec. I tried...

    25 most venomous snakes in the world

    I was bush walking once and came to a quick halt as I saw a Death Adder (#9) on a rock just in front of me. Looking closer, I saw it had a tick full of blood right in the centre of its head. Sort of forming a triangle with its two eyes. Thinking the venom from the tick would probably slow the...

    Thickest common 5w30 oils

    Yes the good thing about Euro rated oils, either full-SAPS ACEA A3/B4 or mid-SAPS ACEA C3, is they must have a min HTHS of 3.5 cP, plus they must pass a stay-in-grade shear stability test. Also if they carry MB 229.5 (full SAPS) or MB 229.51 (mid SAPS) then they are also required to have a...

    Thickest common 5w30 oils

    My go to thick 30 grade oil is Castrol Edge 5W30 A3/B4, it's a Euro grade oil that carries ACEA A3/B4, MB 229.5 and BMW LL-01. Last time I looked it had a listed viscosity of KV100 = 11.9 cSt. It also has Euro levels (~ 1000 ppm) of ZDDP (zinc and Phos) meaning it's "only" API SL due to it...

    That should be a crime. I really liked the Ford AU XR8, great looking rear wheel drive V8 Aussie muscle car.

    Discount oil in Oz.

    Those two Penrite oils make for an interesting comparison: Penrite HPR 5 (5W40) a full-SAPS synthetic with API SP, ACEA A3/B4 and MB 229.5 (they showed the MB certificate at one stage). KV100 = 14.4 cSt, VI = 167, Zinc = 1240 ppm, TBN = 10.4, SA = 1.28% Penrite Enviro+ (plus) 5W30 a mid-SAPS...

    Oil Interval for 2016 Commodore SV6

    I agree, it's the miles driven and fuel burnt that contaminates the oil. With some of my lesser driven vehicles, I would still change the oil at 10,000km but it may have taken me 18 months to get there.

    Discount oil in Oz.

    I'm a ZDDP (zinc) fan, it has three positive effects: - it's a powerful quencher of LSPI (low speed pre-ignition) events in modern DI engines, - it's an antioxidant, so it protects the oil from aging (it's historical first application), - and it's an anti-wear additive that protects the metal of...

    There is also Valvoline SynPower 5W30 full synthetic, it is API SP, ILSAC GF-6A and Dexos1-Gen3. You can get it at Bunnings-NZ for $61 (NZD) for 5L. It's a good oil. Ref. Below: NZ Bunnings web page and Valvoline SynPower product sheet...

    Oil Interval for 2016 Commodore SV6

    Good to know, thanks. That 7500 miles (12,000 km) sounds about right to me.

    Oil Interval for 2016 Commodore SV6

    Hi Mate, Yeah I saw a Holden and I thought Oz, but I should have known that NZ was also part of the ANZAC team. If you are concerned about timing chains, then I would change the oil every 10,000 km / 6,000 miles / 1 year. I believe your engine is direct injected and this can cause soot to...
