    Hi,

    Time for the first oil change since I bought her. I am keen on the Aussie Penrite so I am going to use Penrite HPR 30 for the engine, mainly because of its high zinc content (about 1600ppm).

    I figure that as its the first time I may as well do the gearbox as well - so the question is, can anyone recommend which oil, preferably Penrite, is the go for the gearbox please.

    BTW, he is a 2.0litre manual

    Finally do I need a special tool for the sump plug and gearbox?

    cheers

    George

    George, good choice mate on the penrite. No special tool needed for sump plug mate, just a ring or box spanner. Gearbox will need a 17mm allen key.

    I had been a loyal Penrite oil user (the orange one...) for many years but I have recently been told it's no longer any good for air cooled VW's (can't for the life of me remember why....) so the last time we did an oil change on Abby 1500king used the same oil he uses in his kombi.... it's a Mobil oil designed for air-cooled motorbikes......

    Hmmm,
    Brian and Cathy you are probably right re everyones opinion - bit like asking the people that went to Bathurst last weekend - which is the better car - Ford or Holden. - thanks though for the info re tools.

    Thanks also to Abby, perhaps 1500king might like to throw his 20c in.

    BUT, the recommended oil for the gearbox is still unanswered.

    cheers

    I believe the bottle should have a reference to "hypoid suitable" or whatever. Wear your worst shirt on the day, that smell of gear oil never goes away... I think I used Valvoline last time, which is unusual for me as I steer clear of their engine oil but only had their brand of gear oil on the day I needed it.

    If you don't have the allen key you are welcome to use mine if you're anywhere near Bracken Ridge (I bought one on a 1/2 inch socket which is a good way to go), otherwise Trade Tools usually have a good range of that stuff.

    If you're stuck for a 17 mm Allen key you can use a metric bolt with a 17 mm head and a couple 17 mm nuts jammed together with a suitable spanner; just make sure the drain plug hex socket is cleaned thoroughly so the bolt head fits snugly. Having said that the correct tool is cheap and the best way to go.

    cheers, Tom

    Hypoid 80w-90 for the manual trans and diff(Auto).

    There was an issue with acidity in early GL5 oils, but isn't a problem these days.

    No going to get into any debates about oils...but what I've been using for years is Mobil1 V-Twin 20w-50.
    I also like the fact you can get the stuff at any mobil servo if you need a top up, so don't need to look too hard.

    Also a fan of Joe Gibbs DT-50 (15w-50). There are also a couple of good Mineral oils about (Brad Penn Green oil) but I prefer the synthetics.

    Hi 1500king,

    Now I really need advice - I went out yesterday and bought the oil - Penrite 30 for the engine but couldn't find and GL4 of the correct weight - the only GL4 Penrite was 75 - 80 so I ought it. There was plenty Penrite GL5 80/90 but I had been warned off the GL5 because it was evil for our gearboxes. Now you are saying GL5 is ok. Can you do a Pauline Hanson and ....please explain (please).

    George

    I spoke to a Mobil oil expert at the Sydney Motor Show who said not to use GL5 in VWs or Porsches as it corrodes the synchro rings. VW also say GL4 in the owner's manual (1991).

    The GL4 you have bought is just fine. VW does specify GL4 only for the manual trans(with 40 year old technology oils). The most important part is that it needs to be a "hypoid"oil for the hypoid bevel ring/pinion gears. To date , NO transmission builders have come forward with the mysterious "GL5 corrosion" issue to synchro rings. The entire transmission case is also magnesium alloy, making it a pretty good sacrificial anode against bronze alloys...We've all been looking for proof for years. Been using GL5-MT1 Penrite hypoid for years, no issues. On ALL the geaboxes I have pulled down, ALL synchro damage I have seen is physical, not chemical.

    another basic question

    penrite only has 2.5L bottles which i can source nearby......will this be enough as seem to read i will need 3L

    cant afford to buy 5L and not use most of 2nd bottle

    spoke to mechanic he said 2.5L just enough
