For riders concerned with rising fuel costs or maximizing the range of their motorcycle, this disadvantage is significant. When the engine is started in cold weather, the 20w40 oil remains dense and resistant to movement.
20w40 Oil Long Term Engine Cost: How Increased Friction and Load Drain Your Budget
The extra energy required to pump and circulate the heavy oil places an unnecessary load on the engine, which can also contribute to higher operating temperatures and reduced overall efficiency, particularly in stop-and-go urban riding conditions. While 20w40 motorcycle oil is a popular choice for many riders, particularly in warmer climates or for older engines, it is not a universal solution and comes with distinct disadvantages.
Fuel Efficiency and Engine Load Thicker oils like 20w40 create greater internal friction within the engine compared to their lower-viscosity counterparts. Furthermore, the increased viscosity can hinder the oil's ability to return to the sump quickly, disrupting the designed oil flow dynamics and potentially causing issues with variable valve timing systems found on many newer models.
Long Term Engine Cost: How 20w40 Oil Affects Efficiency and Wear
During this slow warm-up phase, vital components like the pistons, rings, and camshafts are not adequately protected, increasing the risk of microscopic damage that accumulates over many cold starts. In high-performance scenarios, this can manifest as reduced power output, noisy valve train operation, and potentially catastrophic engine failure if not addressed promptly.
