Mobil 1 Oil
 

"Thank you for your inquiry.

At this time we do not have information on the possible future availability of Mobil 1 in a 5W-20 weight. Visit
our web site regularly for information on newly available products.

It is important to follow your owner's manual recommendations in order to
maintain coverage under your new-vehicle warranty. It is our understanding
that Acura's, Honda's and Ford's recommendations to use 5W-20 are driven by
concerns for fuel economy. If you wish to use a Mobil 1 synthetic
lubricant for these applications where a 5W-20 is recommended (Ford, Honda,
Acura), ExxonMobil recommends using Mobil 1 5W-30 or 0W-30. While Mobil 1
5W-30 and 0W-30 are fuel-economy-approved viscosity grades and will provide
excellent engine protection, they might not provide the same fuel economy
as 5W-20."
