Well here it is. My Burb made it to 200,000 miles. Everything is original except for the front hubs which I had replaced pro-actively when they made a bit of noise. All original accessories. The 6.0 engine, 6L90 transmission and MP 3024 transfer case have not required anything but fluid changes. I have replaced interior items such as lock assemblies. I was the original owner and actually ordered this Burb from the check sheet. I bought it in Kalispell, Montana when the Canadian dollar was worth more than the US dollar. (pretty rare).
Going over my records, I had the local dealer do the first change at about 10,000 miles with AC Delco 5w30. After the first change I did the rest with 5w30 synthetic at an average OCI of 6,000 miles. I think, only one other time did I use the OLM which indicated about 10,000 miles.
The oil I used was Pennzoil Platinum (11 times), Mobil 1 (5 times), then Castrol, QS, Formula 1 (Canadian tire) and Valvoline at about 3 or 4 times each. I always used 5W30 synthetic oil that was on sale. After hanging around Bittog, I realized I could get rebates from Pennzoil and QS in Canada so I ended up using a lot of Pennzoil.
I didn't do some of the fancy things like warm the oil before the change, or fill the oil filter, or wait until it stopped dripping. I used Fram filters exclusively, moving up to the Fram Ultra on advice from Bitog.
I had transmission pan drops and flushes done by the dealer every 50,000 miles until the last two years where I pull three liters out and replace them through the fill tube each year. The front diff and transfer case I try do every two years myself since it so easy. The rear diff I was getting done every 50,000 miles at the dealership but just did my first one myself. The rear and front diff had 75W90 syn. For the transfer case, to be honest, the owners manual says to use Dexron VI, but the dealerships in Calgary swore up and down to use Auto Trak II even though that was supposed to end in 2007 when they switched to Magna Powertrain transfer cases. They said because its an Auto transfer case I needed to use Auto Trak II. I can say with accuracy I got 200,000 miles on it with Auto Trak II using 4 wheel drive many times over the winters.
I'm going to step up to 5,000 mile oil changes. The engine does not consume oil between the changes but gets blacker more quickly in the past. I also noticed it runs just shy of 40 psi at 60 mph. It used to run at 40 psi all the time. I might move up to 5W40 during the hot summers and also might go to 0W30 in the winter as I have one cold start each afternoon at the ambient temp, which can be as low as -30 C once in a while. Currently the morning start is done at 50 degrees inside my heated garage in the winter.
I like the truck enough to budget for a transmission rebuild if it goes. Also, I'm dreading the infamous oil pickup O ring issue. Also, a few of the exhaust manifold bolts need replacing. So far so good. Anyway, pretty much rust free and I've spray it by hand with Krowne rust preventer. Looking for 250,000 miles.
