Do you need to warm up and older car ?
Hi I have a 1998 toyota corolla . I use synthetic blend oil . But do I still need to let the car warm up and if so for how long?
When I start my modern cars, I let the engine run until it comes down off the fast warm-up idle, then I start driving it. That gives the oil pump enough time to get oil fully circulated through the motor, which is the biggest cause of wear on start-up. After that, I don't drive with any kind of a lead foot until the temperature gauge is close to normal temperatures.
Your car is considered to be a modern car and in modern car, you do not need to do warm up.
It doesn't matter whether you have computer controlled fuel injection or not, metal is metal and it operates on an expansion coefficient with other metal parts that are designed to have very specific clearances at operating temperature. Putting stress on parts that haven't achieved proper temperature is accelerating their wear. Car manufacturers want you to start your car and drive away so it will wear out faster so you need to buy a new one. I always let my vehicles warm up before putting any stress on them. I don't care about wasting gas compared to the price of a new engine, trans, differential, etc. Everyone has their own opinion. That's mine.
Well my car takes whoever I idle down. That's another reason I asked . But when it does start up it usual is right above the 1
