Then, which oil is thicker 5w30 or 10w30?
A higher viscosity oil, such as 10w30,will flow slower at low temperatures compared to a lower viscosityoil like 5w30. A higher viscosity or thickeroil will seal better than a low viscosity oil. Athicker oil will also provide better lubrication of criticalengine parts.
Also, is 10w 40 thicker than 5w 30? A 10w-40 motor oil is a thicker oilat startup than a 5w-30 motor oil. Therefore,10w-40 oil clings to the engine's moving parts morethan the lower viscosity 5w-30oil.
Likewise, is 5w30 or 10w30 better for winter?
At operating temperatures, both oils will have the sameviscosity (30) and will flow and protect identically. If the oilwill be in the engine during winter and you live in a placewhere it gets cold during these months, use 5w30 oil. If itwill only be in the engine during the summer, use10w30.
Can I replace 10w30 with 5w30?
0w30 and 5w30 are more commonplace now than theyused to be. The 5w30 has more viscosity index improvers vsthe 10w30 so technically the 10w30 would have moreoil that lubricates the engine. But no it won't hurt to use5w30. The 5w30 when cold will still be thickerthan the 10w30 when hot anyways so it doesn'tmatter.
