Amsoil does well in these engines and it's available in larger pack sizes like this and it can be shipped to your door. PM Pablo for pricing.

I'm going to say Pennzoil Platinum Euro 5W-30 with its A3/B4 rating is the best oil for your truck.

Mobil 1 is good, but no longer substantially better than many others.

Some 5w40's should be perfectly suitable for your truck, but with 40K it's nowhere near necessary unless you're working it real hard.

Nothing wrong with M1, if it's serving you well, why stop? M1 European Formula 0W-40 can probably be used in the Passat and is an excellent oil.

If your truck lives an easy life, synthetic oil isn't necessary for any phase of its operation parameters.

Any of the name brand synthetic oils at Walmart will be fine. As will M1.

Don't believe everything you read on the net. Including BITOG. M1 5-30 is one of the best 5-30 oils.

Your ~6,000 miles a year include a lot of short hops? What does its OLM read when you're fixing to change?

That LC9 is the aluminum block 'LMG' with 799/243 heads and VVT + AFM. They're typically about as sturdy as an anvil.

I've owned a 2010 Silverado with a 5.3 since it was new and I've used either Pennzoil Platinum or Mobil 1 in it and haven't had any reason to switch to something else. Those engines do not require a Dexos rated oil, that started in 2011 and for many of those engines, nothing but conventional oil was ever used in them and they still live for more than 250,000 miles.

Mobile phones are great to have. Ö and Mobil is the lubricant line that ExxonMobil elected to stay with.
