5-40 rotella T synthetic Vs. delo 400 15-40
Is the pour point the point at which oil stops flowing.
If this is correct then according to the spec sheets Delo 400 15-40 would be better then rotella T 5-40 synthetic in cold weather starting????
pour point TBN
rotella T 5-40 -30c 10
delo 400 15-40 -39c 11. 3
I always thought heavier weight oil flowed less??
Both oils are hydrocracked, which means they can classify them as synthetics even though the base stock is mineral verses man made.
group III oils hydrocracked mineral base.
group IV oils are man made base.
Someone with more knowledge please step in and clarify.
