Like it says, I'm the new guy with a 2020 3LT Traverse. I'll give you a little background, before I ask a few questions.... My wife spent 20 years and 300,000 miles ( 2000 to 2012 and 2012 to 2020) in Chevy Tahoe's and was ready for something different. All the Tahoe's survived the 300k miles with everything they left the factory with and went that distance with only maintenance items like oil and filters and consumables like tires and brakes. Fingers crossed on the Traverse. I never thought I would own a V6, D.I. engine / FWD vehicle, yet here I am. I own two Duramax's, a 2005 w/ 325k miles and a 2011 with 118k miles.
She really wanted the 2nd row bench, so our local dealer swapped cars with a dealer up in Lompoc. Our car arrived with 280 miles on the clock. First impression was good. It's a real jump in technology from the 2012 Tahoe! It's quite zippy and it sounds a bit F1-ish as the 9 speed bangs through the gears. It also has the tow package.
So I get it home and give it the once over. ( I've been a heavy equipment / crane mechanic for 30 years so I always inspect everything, even brand new cars) First thing, the engine oil dipstick shows dry. Zero.... Nada. Well that sucks. Rather than add some, I drain it out instead. 5 quarts come out plus the little bit in the filter so it was just a little low. What was concerning was the oil itself. I use Mobil 1 in everything I own . In the Tahoe's I always went 8k miles before changing it. Well, at 280 miles the oil in the Traverse looks worse than the Tahoe at 5k miles..... no joke! It was dark and nasty. I removed the oil filter and cut it open. It had some kind of debris in it. It was a factory Delco filter, which is made by Champion Labs... a company with known quality control issues. This is a photo of the actual filter. See that crap? WTF is it? Who knows.....
So I swap out that filter for a Amsoil oil filter. I think Amsoil itself is a over-hyped product, but their filters are no joke. 20 micron filtration at 98.7% efficiency beats anything on the market. Hopefully the M1 5w/30 + the Amsoil filter let the timing chains live a long and trouble free life. Since swapping out the garbage oil and filter the Wifey has driven 1000+ miles. No oil consumption has been noted and the oil color is still amber / honey clear...thank goodness. The Wifey also thinks the engine has quieted down some with the M-1 oil....
But now I'm all paranoid about the ATF. The 2020 has no dipstick, you use sight plugs to determine the fluid level, so this weekend I am swapping that out too for the Valvoline synthetic Dex VI ATF. Hopefully, there are no surprizes there. For both the engine and transmission drain plugs I am swapping them out for magnetic ones. Every car I own (11 total, I own a construction company + 2 kids cars) has magnetic drain plugs and every one of them is covered in super fine particles that the filter has missed....Some say these particles are too small to hurt anything, but these 3 timing chains have me a bit nervous so I'm thinking every little bit helps.
This D.I. also has me a bit nervous too. Horror stories about gunked up intake valves and ports abound on the internet. Well, both my diesels are D.I. engines too, and run seemingly forever with out worry. Some say Gas D.I. engines are much different than diesels and if you dont put a catch can in the PVC system you're a fool. So, Who's driven 100k miles without a catch can and no issues, or who has put a catch can on a late model Traverse and is shocked by all the crud it's catching? Any one?
I'll let everyone know how the ATF swap goes... but so far the Traverse appears to be a winner.... Thanks for having me.
