Hi all,

The other extreme would be me ,I had a VL 3 lt OHC Commodore (Nissan 6) in 12 years never changed the oil or
the filter ,It burned a little oil but didn't smoke and leaked a little oil (gaskets) and all I did for 12 years was to
top up the oil ,after 12 years the LPG system stuffed itself (corroded out ) never even used inhibitor ,the motor cooked itself
I had water in the sump oil and oil in the radiator so I replaced the head and new head gasket replaced the gas converter and
it's still running fine ,it probably got topped up with a few litres per year as that was what it lost. I have bought many car engines from
wreckers for $50 , the VL engine cost me $50 ,I just don't see the point of spending hundreds of dollars on servicing when I can buy
a motor for $50 ,these days motors cost me $200 and that's usually with a good gearbox thrown in.

I drove that VL with oil in the radiator and water in the sump until it would not run anymore ,it had about 15 lt of
sludge (water and oil) in the sump when I replaced the top end.


If I have a good engine I will change the oil every 10,000 ,plugs last me 40,000

The old Corolla and Laser I would only change the oil every 10,000 ,sometimes a little black oil means nothing , I've
changed oil on lots of diesel motors and you never get all the old black oil out when draining, when you put new oil in
it's a little black from the start.

Also seen a lot of new reco motors stuffed because people never changed the oil.
