I'm surprised no one updated the info for you. The recommended oil for the 2,7 is full synthetic. 2.7 uses Dexos1 gen2, which is full synthetic. Specification Use full synthetic engine oils that meet the dexos1 specification. Viscosity Grade Use SAE 0W-20 viscosity grade engine oil for the 5.3L and 6.2L V8 engines. Use SAE 5W-30 viscosity grade engine oil for the 2.7L L4, 4.3L V6 and 6.6L V8 engines. Cold Temperature Operation: In an area of extreme cold, where the temperature falls below −29 °C (−20 °F), use SAE 0W-30 oil. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures. There are lots of oils that meet the Dexos1Gen2 spec, in several viscosities. https://www.gmdexos.com/brands/dexos1/index.html
3.0 is a couple 100 lbs heavier, based on payload ratings. There is a weight calculator if you're wanting to compare weights for specific models and trim levels. https://www.gmfleetorderguide.com/NASApp/domestic/weightcalc.jsp?vehicleid=21796®ionid=1&step=1

Always was a 5 year thing for the free phone remote. Purchased after spring 2018 and it's no longer 5 yr free. (Of course 'free' is relative. Just means everyone pays in purchase price, and non-users are subsidizing those that want the feature)
It does not 'limp' at 2 gallons. It does not even limp at 'empty'. When it does Speed limit is still full power, but the max speed is reduced from the normal limit of approx 100 mph. 'The term Limp', as normally refers to a 'low power mode' At approx 1000 miles to empty it gives a (one time) message indicating approx range remaining (like fuel range, it is an estimate base on 'recent' usage rate) From about 300 miles range, it will give a message indicating approx 'miles to empty' at each start cycle. When it is empty, escalating warnings/actions begin. The first is a warning - '500 miles til 65 speed limit '. For that 500 miles, it still runs normally, but there will be a coundown screen on the dic that cannot be acknowledged so it goes away. I've intentionally taken my '18 L5P this far and ran about 60 miles looking at the countdown...... (never tried it on the LML) At 500 miles, speed limit to 65 begins and warning of '75(iirc) miles til 55 mph speed limit'. Then 5 mph speed limit. For most, the 500 miles is going to get the truck to it's next gets fuel stop. Most fuel stops also have DEF. Until 2020MY the def bargraph didn't exist. DEF DIC page would indicate 'OK' until the tank was down to approx 30% remaining. Then the page dispayed the approx %. Those trucks also gave the 'miles to empty' warnings, and when empty gave the 'miles to speed limit' warnings. 2011 LML did not have any sort of def gauge. It's not that tough to manage. (and LML had a small (5.3 gal) def tank. DEF level sensing wasn't super accurate on LML either. Mine wouldn't hold 5 gallons even at the 300 mile warning level (but lots of others reported being able to) At the time, 2.5gal boxes were the most convenient for me -- so rather then dealing with a part box I changed to partial fill and just adding one. 1200 miles per gallon, so one box about every 3000 miles. Point of the LML stuff is that part fill is always an option. Yes, there are trucks out there with def systems in need of repair. And we are learning that the DEF display doesn't operate like a typical variable gauge.
My LML got between 1100 and 1200 miles per gallon def not towing (which was most of the time) My L5P seems to get a little less, but still around 1100 (hard to be precise, since a fill lasts so long, especially with the larger 7.0 gal tank) Don't forget that when it gets to 'empty', you still have 500 miles before it limits to 65 mph, and then another 75 miles to 55 speed limit. Even not towing, you probably need fuel within that range -- and the fuel locations likely also have def. (either boxes or bulk)
I you don't want to use steelies, dealers here usually have new 'take-offs' from trucks that had aftermarket wheels installed when they bought the truck. Means you can have factory GM wheels with whatever winter tires you prefer. There are also several tire/wheel package shops that deal in take-offs. Presumably they get most at a 'wholesale, price from the new vehicle dealers that install enough aftermarket sets that they can't use all the take-offs.
Don't ignore the brakes. A 2500 has significantly heavier frame and significantly bigger brakes. The 2500 frames have had 2 major (3 if you count the 2020) updates since 1998. I'm not sure about the early 2000's version, but the 2011 2500 update came with much bigger brakes (and the exhaust brake, if you are considering dmax) Old article, but includes info/pic about frame, front end and brakes: http://www.maxxtorque.com/2010/12/2011-duramax-lml-review-built-to-tow.html
redwngr replied to Carolina's topic in 6.6L Gas V8 & HD Transmission Powertrain (L8T/MYD)Yes, I'm fully aware of where the 6.0 is installed. Question is, does the 6.6 gas equipped 2500 mileage like a 1500 5.3/6.2 (and 2500 6.6 dmax) or does it get mileage like a 2500 6.0L? (or somewhere in between) Everyone blames the 6.0's mileage on the weight of the 2500. I get that and understand....but the dmax 2500's is in the same chassis as the 6.0, but (in my type of use) gets mileage similar to the 1500 5.3/6.2. 6.0L, or now the 6.6L gas, in a HD is still the right truck/powertrain for many. I'm definitely curious to hear more about the real world impact of the changes to the HD gasser.
Sounds like it might be overusing, but even if it is, why would you haul def in the bed? It's available anyplace you can buy fuel and also at any autoparts store or department store with an auto section.
