Interesting. The 6.2 in my 2014 Camaro calls for 5W-30. The 5.3 in my 2007 Tahoe calls for 5W-30.
Question: Why dexos1 0W-20 engine oil?
Answer: The new 5.3L and 6.2L V8 EcoTec3 engines available in the new 2014 Silverado 1500 and Sierra 1500 trucks are the most fuel efficient and technologically advanced engines in the market. These engines feature an advanced combustion system that maximizes the potential of the direct injection (DI) fuel system, active fuel management (AFM), variable valve timing (VVT), two stage oil pumps and other technologies. The dexos1 0W-20 oil supports these technologies and is an enabler for the engines’ improved fuel economy performance.
So do tell. Do those systems take a break until the oil is up to operating temp and has thinned out?
I doubt it.
The truth is an engine runs just fine on a range of grades perhaps not optimal however.
And in the real world going from a 30 grade to a 20 grade will show no fuel consumption difference.
Heck my charger gets the same fuel economy whether I've got a 20 grade in the sump or a 40 grade
Posts like that are hilarious. Shows how little is being understood.
Chalk it up there with tighter tolerances necessitate using a thinner oil.
