You are in a tricky situation, the oil you use is a good quality brand and shouldn't cause any problem, but I would follow the dealer's advice and switch to a 10w-30 grade oil. I'm sure you'll find Valvoline make one, so you can stick to the brand you like and trust.
We haven’t had any other reports of cam chain/gear wear on the Corolla, so it’s hard to say it’s a widespread problem, but the company stepped in and covered half the cost so there’s not a lot to be unhappy about.
In any case like this you need to make sure it's not somethingsilly, like something rattling round in the ashtray, but having ruled all those possibilities out you would have to conclude that the cause of the rattle is probably a fault from the production line and therefore should be covered by the warranty. I recall trying to find the cause of the fuel starvation in an old car of mine some time ago. I checked everything I could think of, carburetor, fuel pump, fuel filter and fuel lines, only to find after months of trying that it was caused by a scrunched up piece of masking tape the spray painter had kindly dropped into the petrol tank when he'd painted the car. Every so often it would block the pickup in the tank. Asking you to foot the bill is over the top.
Hyundai claims an average fuel consumption of 4.7 L/100 km for the i30, with 4.1 L/100 km in extra urban driving and 5.7 L/100 km in urban driving. The fuel consumption figure used by Hyundai, and all other carmakers, is derived from the standard test conducted in a test laboratory, not real life. The purpose of publishing the test result is to provide buyers with a means of comparison between makes and models, it's not really meant to be taken as a real life measure of what you would get yourself. But it shouldn't be too far from the mark either, and I would reckon a 50 per cent variation is too much. More to the point you need to take into account your driving conditions, do you drive in flat or hilly conditions, do you have a lot of stop-start traffic on your way to work, do you mainly do short trips. The consumption you get is on the high side, and you could ask the dealer to check your car to make sure it is running well, but I believe the problem will be environmental.
Given the your low annual distance traveled and the fact that it's out of warranty, I would think you could stretch the oil change period to 12 months, but no longer.
Like most current model Toyotas it has a timing chain.
You can fit LPG to your Corolla, but it is recommended that you use an injection system because of the risk of backfiring with the older system and the damage that could cause to the plastic intake manifold.
It's still under warranty so you should persist with your dealer and have him demonstrate, perhaps by driving another car with the same drivetrain, that yours is normal. You could also have a trusted mechanic drive it for you and give you an opinion on it.
Red is one of the worst colours for this sort of problem, it might look great, but it's a colour to be avoided. There's not much you can do about it, other than repainting the affected areas. It could be worth consulting a paint specialist, such as Graeme Cuthbert (0422 444 335) and get an opinion on what action you cold take to fix the problem.
