Vehicle is a GMC Sierra 5.3L 4X4.
Thought to run Syntec 0w30 through two OCI's on the oil life monitor? Is this a good idea? Is it recommended for extended drain. Paramount concern is condensation through the winter. How does water degrade this oil - physically or chemically?
Ran XD-3 and Duron in the past, really like the price of XD-3 but availability was a pain and it's not specifically recommended for year-round service, I think Esso recommends to 20degC or so. Just looked at the VOA for XD-3 and Syntec - and Syntec has moly among other things, does this make it a "premium oil"? Does anyone know if it is specifically recommended for year round use? Sorry, really starting to ramble there.
Anyway - thoughts anyone?
