The reasons why a lamp may not be working can be varied. The most common cause is the use of poor replacement globes. Like all components, globes have a set life span and will need to be replaced. When one globe does go, replace both because they will have the same life span and the other one will probably fail soon after the first. Also use quality globes, which are normally available from an auto-electrician and will last longer. Heat can be a problem affecting globe life. Globes heat up quite quickly when in use, and can fail if there's not enough air flow around them to dissipate the heat. It's a particular problem with high-mount stop lights which are often contained within small, tightly sealed housings with little cooling air flow. Added to which it is not uncommon for owners to fit incorrect globes, usually globes of too high a wattage, and these can overheat more easily in the stop-light environment, sometimes to the point of melting the socket. Water is another cause if there's a poor seal around the lamp.
Your friend is basically correct, the Gen III V8 is calibrated to run on ULP, and running it on PULP would produce only a small improvement. Overfilling some engines with oil can lead to damage, but in the case of the Gen III it seems there is no danger. It should only be done as an added precaution on engines that do consume oil, and I wouldn't follow the practice if your engine isn't devouring oil. You sound like someone who keeps a close check on the oil level, so I would recommend you fill it to the correct mark and keep monitoring the level. The number of problem engines is quite small, Holden says it is less than 2 per cent of V8s, so I wouldn't be concerned unless your engine is actually using oil. The fix implemented by Holden from the start of VY has done the trick, according to engine rebuilders.
I would definitely dispute the need to do anything in this case. You should be able to detect a blocked injector. The engine should run a little rougher at idle and under load, but if it's not, I would suggest there is nothing wrong. The fuel consumption numbers you quote are in line with what I would expect from a VX II Commodore V6.
Like you, Mick, I can't explain why the acceleration figures for the supercharged Commodore should be shown as similar to the non-blown car. It doesn't stand to reason. The figures shown on Holden's website are not Holden's own performance numbers. They are taken from a comparison test done by other people. Holden doesn't publish official performance data. The numbers I have suggest that the correct 0-100km/h acceleration number for the normal V6 is about 9.2 sec and the supercharged car gets the job done in about 7.5 sec.
I don't like the VY styling either and agree that the VT and the VX are the best-looking cars in the recent series of Commodores. I would have to recommend the VX Series 2 if you can afford it. It's the newest model of the two, so it is a better bet. The VX also has the benefits of the development that takes place over the life of a car. Build quality is at its best, and any problems have usually been fixed. The VX 2 will also have a lower odometer reading, which means its useful life to you will be longer and it will have a better resale value when you sell it. But there isn't much wrong with the earlier model, so it really comes down to what you can afford. In terms of reliability there isn't much between the VT and the VX, so I wouldn't worry about that.
