Your car is always talking. Unfortunately most people have problems understanding the language. Understanding the controls, the feel, the wear patterns and noises your car is making are vital in the proper operation of any vehicle. For example; if a dash light is red in colour, the situation requires immediate attention. Failure is imminent. The orange colour indicates attention is required; however; damage is not imminent. A green light is a go. Every car come equipped with a wealth of this type of information as standard equipment. It’s called the owners manual. Read it.


My Toyota Corolla 1992 has an oil light problem. For the last two months I’m having this problem. When I start the car my car and all dash lights go off. After 15 to 20 km the engine oil light comes on when I stop. When I start off again the oil light goes off. I checked engine oil level always it’s OK, no leakage, can you please tell me what the problem is?


The oil light comes on when there is a drop in oil pressure. In most vehicles this occurs when pressure drops below 8 psi. I would avoid using the vehicle until this situation is remedied. Running with low pressure will eventually lead to engine failure.

We have an SUV and would like to install pop-up sunroof. Is it technically / mechanically correct and what would you recommend if it is not correct. Really appreciate your advice/opinion.

Back in the 80's pop ups were hot! Back then I would not hesitate in stalling one. That was back then today I would avoid this option .First off they compromise the safety of the vehicle in the event of a roll over. The have a tendency to leak as the rubber ages. They reduce the value of the vehicle. Most importantly for can't shut the thing off...when the sun is beating down on you on a hot summer's day there is no way to block the sun out , in the winter you can feel the cold as it radiates in. In short avoid aftermarket sun roofs.

Guess I must be getting old.
