I'm reposting this here as it seems like a more appropriate place.

 

I'm thinking of changing out all of my fluids in the truck and I'm hoping some people could share what brand and type of fluids/oils you use. I have the Autotrac system on my truck.

 

Transmission:

 

Transfer Case: (heard GM AutoTrak II is the only way to go)

 

Front Differential:

 

Rear Differential:

 

Engine Oil:

 

I'm not looking long winded studies or anything. Just curious what people are using.

For the record, this has been covered a lot on other threads. If you want more information, I suggest you do a search.

 

Both of my trucks;

 

Transmission: Royal Purple ATF

 

Transfer Case: GM AutoTrak fluid.

 

Front Differential: Royal Purple

 

Rear Differential: Royal Purple

 

Engine Oil: Royal Purple, Rotella T Synthetic (Silverado only), Mobil 1, whichever is cheapest when I need to do the change. As long as you use the correct weight/grade synthetic that is API certified you realy cant go wrong.

Running Mobil1 currently in the crankcase but will switch to Valvoline Full Synthetic on next change. OEM fluids are still in the trans and diff at 10,000 miles.

The only thing that I have changed from OEM is the engine oil and I switched over to Mobil 1 at 2K. Jim, I am curious why you are going from Mobil 1 to Valvoline full syn.

From what I am reading, it is a full synthetic lubricant and outperforms Mobil1 hands down. Mobil1 (which I have used for years) used to be 100% synthetic but now uses petroleum base for at least part of its formula. Apparently this changed in 2006 as allowed by government regulations... It's still sold as synthetic. I've read that Synpower actually is several times better at preventing wear than Mobil1 in independent testing.

 

I'll try to find the article and post a link.

I used to use Valvoline 20w50 Racing in everytyhing I drove back in the days before this light weight oil crap. I loved their stuff. I still use their gear oil in everything. I'm looking forward to switching to the Synpower.

 

EDIT: Oh, and I can't stand syrup. I won't even eat at a table where it is being served. Who can get past that horrid smell? Sheesh!

I don't use either of these oils so I have no axe to grind. As for what I have read, Vavoline is still a group 111. It may have a small amount of Pao. Mobil 1 is mainly Pao with some (who knows for sure) amount of group 111.

 

There is just one of several test that valvoline showed better ware numbers than Mobil 1. Of course their marketing jumped all over it. Any way they are discussing this right now on http://www.bobistheoilguy.com. The thread I believe is Valvoline vrs Mobil 1 round 2.

 

Have a good one,

I've been reading that. If you throw out the opinions over there it's pretty good reading. (kinda like this place)

      Oil Consumption

      By Chuck FB · Posted

      Ok that confirms the extra quart theme they are still going with which must mean they have noted some initial use more so then some engines and probably the bigger factor in all of this probably isn't the engine so much as its the insane distance or OLM that lulls a lot of the driving public into driving their new vehicle off the lot and not even doing one short interval oil change because the manufacturer doesn't say different and if the dealer follows that logic as well. Selling the rarely needing to be serviced concept seems to go over well with the public that wants to get away with as little as possible for dollars spent on the vehicles maintenance and I bet there are 3.0 engines just like other vehicles out there that never have their oil checked by the owner which goes back to why they probably felt the need to add that extra quart to avoid a costly theme.    Speaking of cutting filters open, it was probably over two years ago now that a youtuber who buys vehicles to do longer term reviews and pulls a fifth wheel through the mountains of Colorado on summer trips and that becomes part of the testing. Anyway he had a GM HD with the 6.6 gas and a Ford 250 with the 7.3 gas at the same time and of no surprise the Ford had more power etc but somewhere along the way in the few thousand miles he put on the truck, he changed the oil and was seeing glitter and cut open the filter and yeah, things were not looking spectacular. The truck about that time or soon after seemed down on power compared to what it had been and then threw some engine code, I expect the cam/lifters were failing and so he brought the truck back to the dealer and made some deal to get out of it as he knew it would sit for months waiting on a new engine as they were so backlogged at the time. He kept the GM for some time after that using it exclusively until he sold it after buying his next vehicle to do a review on. Definitely the filter can tell a story when things are starting to go sideways, but it would be a sickening feeling to cut it open and be faced with an ugly mess like that and be running a magnet through the pleats and the oil on the dirty side of the filter and see all the fines sticking to the magnet.    The dealer may have some ideas based on experience as to where that coolant smell is coming from, I would imagine if they can't find it but its smelling they would put dye in it to they could give it a run cycle and use the black light to see where it pops up, if its a hose connection, water pump, rad or even a head gasket etc.

      charm.li (website) has the vehicle-specific diagnostic procedure for that code, you can use to find what the cause of it is.

      Oil Consumption

      By KARNUT · Posted

      It’s at the point of amusement. I’m retired I have time. It’s fun seeing people try to convince me I’m using oil. I’m buying oil at the prescribed time. It gets drained and new goes in. Do I add in between, no. My oil doesn’t even get dirty in 5k miles. I don’t even see any drop on the stick. I check in the same place. All is well.
