At Chevron's site, the well-known Delo 400 Multigrade 15w-40 is listed. They also sell a Delo 400 10w-30. What's the difference between the two? The 10w-30 is listed with all the monograde oils, while the "Multigrade" Delo 400 only lists the 15w-40.
If the 10w-30 is the lighter "brother" of the well liked 15w-40, then it might prove to be an excellent choice for many of todays cars...
