Cold start refers to starting an engine when the ambient temperature is low or the vehicle hasn't been driven for a long time. In such cases, the oil is thicker and only reaches its optimal operating temperature after a few minutes. This can increase wear if you immediately floor it or drive off right away. Modern Suzuki models often have start-stop automatics or heating systems that mitigate the issue. But what do you guys do to get the engine warm quickly?

A cold start occurs when the engine oil hasn’t reached its typical flowability at low outside temperatures and the combustion chamber temperature is still far below the target operating temperature. Especially with Suzuki models, which often come with water-cooled four-cylinder engines, this means the oil pump initially delivers relatively thick oil. This delays lubrication of the bearings and piston rings, increasing friction and wear—especially if full throttle is applied immediately.
Modern Suzuki vehicles have several features to ease cold starts: start-stop systems reduce stress when shutting off the engine, an integrated coolant heating system (in newer models) keeps the coolant slightly warm, and electronic fuel injection automatically adjusts the air-fuel ratio to ensure stable idle torque. Still, it’s wise to let the engine idle for a few minutes after starting so the oil can reach bearing temperature and fully coat the piston rings again.
In practice, I recommend not immediately revving a cold engine on a chilly morning. Instead, gently press the accelerator, keep the RPMs around 1,500, and only gradually open the throttle after about 30–45 seconds. For sportier models with a V12 badge that I personally maintain, a brief, gentle revving can help oil circulation without causing extra wear. This preserves engine longevity and keeps driving smooth.
