That might fly driving a short trip from home to work, dropping kids to school. Actually there is pretty good evidence that low viscosity oils are better in short trips. It makes sense, the golden rule of lubrication is: As thick as necessary, as thin as possible.

i know you are talking about low 0-20 etc with lower hths.
in my case ,i told you i do a lot of short trips and a DI engine. i use 5-30 as we agreed. if i use a 0-30 thinner by visocsity=100c and lower VI=40C same hths 3,5,will it be better for short trips?
or bcs. hths in the oils i use x-30 dont have any diffrence at all bcs. hths is all that matters and both grades have same hths?
