Why would one use 10w30 when 5w30 is available?

Same question for 5w20 when 0w20 is available?


Same question for 10w30 or 5w30 when 0w30 is available? Or am I missing something?

Because 10W-30 has more base oil and less viscosity index improvers than 5W-30.

More meat and potatoes. That makes SAE 30 Tri-Tip !

In this age when almost all SN oils are semi-synthetic, this is no longer true. 5w-30 is is more likely to have more Group III+ than 10w-30, and maybe even some Group IV.
