honda accord/chevy silverado

[mobilaltima]

two vehicles in question, trying to decide which oils to run in both.

2008 Accord, 2.4 liter, currently running Castrol Syntec 5W20. I see they sell Castrol 0W20 at AAP, and Mobil 1 Advanced Fuel Economy 0W20 at WM. Which oil has shown to have a better UOA in this particular engine?

Next vehicle is a 2009 1500 Chevy with the 5.3, out of warranty for a while now , has 137k miles. Seen on here that the vortecs tend to have a better UOA with a 40 grade, which would be the best oil to run out of the following: GC 0W30, Belgian Castrol 0W40, Mobil 1 0W40, or Castrol Syntec 5W40 Euro Formula? will stick with a 5k oci in the honda and go down to 15% OLM on the Chevy.

We have nearly the same Honda engine in our CR-V. I have been thoroughly impressed with Mobil 1's AFE line of oils. I have run 0W-20 in ours before and it ran very quiet and smooth on that oil. I currently have 0w30 in it now, but will go back to the 0W-20 on the next oil change. Same in the Acura...the Mobil 1 Advanced Fuel Economy oils run very quiet.

I'd use the Mobil 1 0w30 in your truck as well.

Why do you follow the OLM on the Chevy, but not the MM on the Honda? Your Honda should prompt for an oil change in the neighborhood of 7-9k miles, which is absolutely doable on any synthetic oil. Honda's K-series 4-cylinder engine is a peach, and returns good used oil analysis on most any oil.
