The traverse should have come from the factory with synthetic oil. All the direct injection motors should. The high heat will bake the oil. I have seen the inside of a motor with mobil 1 and one with regular oil. The difference is day and night. The synthetic can handle heat. This is the main problem with the timing chain, not getting oil to it
All of the 2012 and 2013 are now using Synthetic or a blend...
The main problems with timing chains was with the 09 and was caused be a design flaw with the oil journals feeding the timing chain cover. They were not large enough so as the oil aged it would flow slower and caused the chains to over heat and stretch.
The issues went away as when the 3.6 DI Camaro was introduced the journals where made larger in the blocks this fixed the issues.
Since then GM now seems to be switching all of there new models engines to Synthetic oils.
That is good to hear. I own a 2009 ltz. My traverse had broken valve spring, That is how I seen the inside of my motor. But from the beginning the service manager told me I would be ok with the timing chain because the mobil 1 would get to the chain. When the work was done the chain was good but he replaced it any way. He showed me how clean my motor was and how the oil drained, compared to a traverse sitting next to mine,That looked like some one dumped mud on top. The oil had baked and become hard
Got to me careful with short OCI. If you look at oil analysis trends (and you can send your own oil off for a test if you like), using good synthetic oil and waiting 10k miles (even longer based on driving), you will have low engine wear. During the detergent cycle (a few hundred miles after changing your oil), you experience the greatest engine wear. So, more frequent oil change intervals suggests greater engine wear. I am not asking anyone to take my word for it... look it up or do your own test.
Just avoid the blend stuff.. I'm just going to run full synthetic in my 2013.. Of course the only reason will be just to keep the warranty folks happy. Not going to give them a reason to void it.
It will not affect the Traverse motor one way or the other.. Given the engine from 2010 to 2013 are unchanged.
The 09 engines have issues cooling the timing chain so broken springs are very possible if the chain is stretching so valves , springs and the cam could all be damaged.
Fact is they have to remove certain minerals from the oil just to be able to blend it.. So just run full.. Unless you don't care then just run standard oil. The 09 is the only one to take care with the fact is you just have to change the oil often to avoid damaging the chain..
The number one factor for engine wear is accsesive idling.. Starting the engine is the next hardest thing..
The wear from changing the oil is so minimal you would be talking days if not hours in the difference of the engines overal life..
I just had the oil changed with semi blend, but now that I am going to do the rest of the changes myself, and hoping I find the full synthetic on sale, can I just swap from semi, to full syn. without harm?
