What are the advantages of running this weight oil as opposed to a 5w30? I noticed Mobil 1 lists it as a "European" car formula



Better thermal viscosity protection under operating temperatures. I drive quite HARD.

For "realistic" purposes a 0W40 is a 9.5 weight oil at 80 degrees. The only time it's quite "thin" acting is in cold weather and that's a good thing.


For ref - At 80 degrees during start up.

0W30 = 7 weight
5W20 = 9 weight
5W30 = 12 weight
10W30 = 17 weight
10W40 = 20 weight
20W50 = 32 weight
