This ole thread was an entertaining great late night read.     It spanned 3 years and the discussion was lively, and at times, testy, as most oil threads are.    The topic about "t

Yes, they can go sideways.  But, if people keep it respectful, these kinds of technical discussions on forums can be some of the best threads for revealing things to the layperson.

Mobile 1 0-20, Wix XP filter. Change every 5k. I personally don't care what the computer says. Every 5k.

Any major brand 5W30 full synthetic dexos approved. Brand doesn't matter as long as it is dexos approved. Get a good quality oil filter. AC/Delco, Wix, Napa Gold or Platinum are my preferences. And yes going off the oil life monitor is just fine in most circumstances. Leave it at that and live stress free!

 

Requires 0W20 not 5W30.

 

To the OP, I plan on using Mobil 1 full synthetic with a Mobil 1 Filter when I change the oil. The 3 times before was under the 2 year maintenance so this coming up time will be the first time doing it on this truck.

0w20. Don't run the risk and run a different weight. Any brand will be fine as most of the 0w20 market is Dexos licensed. I personally use Pennzoil Platinum in my HD(different weight than the 5.3 and 6.2 which are 0w20). $24 a 5 quart jug at Walmart. I run in it my truck and my brother's Camaro SS so I buy like 3-4 jugs at a time and it gets me two on my truck and one Camaro change.

I do all my own maintenance and either use Mobil 1 EP or Pennzoil Platinum, either with a Mobil 1 filter or K&N filter. Usually the local parts store has a deal with either of those oils, and then the filter like a $4 upcharge, then go to wally world for another jug of the same oil for around $20-25

Like stated above, run 0w-20 that is dexos rated and you will be fine.

 

AC Delco filter along with Wix, Car Quest house brand and NAPA are good choices for filters.

Personally I think you're wasting money, especially if the oil you get is full synthetic. Full synthetic last 10,000 miles. The reason the oil life is set for 7,500 is because the factory and dealerships use synthetic blend. Regular oil last 5,000, syn blend last 7,500 and full syn last 10,000. But, if it makes you feel better than go for it. Those #s are all city driving also, so if you do a lot of interstate or highway driving then you can go even longer, but I always go by city miles.

Keep an eye on Amazon and Walmart if you go Mobil 1, you can get sales at $22.88/5qt jug with free shipping. Don't even have to leave the house.

I was using a Penzoil full synthetic for a while. I found the engine went into V4 more often and I noticed more leakage of oil around my catch can connections probably due to the slightly lower viscosity of a full synthetic versus a synthetic blend. Last 2 oil changes I had to go to the dealer for recall work and decided to just get the standard AC Delco synthetic blend 0W-20 to save money and I swear the engine feels like it runs better and the oil leaking around my catch can connections has dropped by at least 90%.

 

In my opinion, if you're like me and change the oil every 5,000 miles, just stick with the standard AC Delco synthetic blend 0W-20. You're already changing it 2,500 miles earlier than what the manual and oil life monitor recommend. If you're consistently pushing it to 7500 miles between changes, I'd probably stick with a full synthetic.

Vettes call for 5-20 Mobile 1 Extended Performance that I get at wally world for $28 and change that's what I have run with no negative effects.

 

RT

 

The Vettes run 5w30 not 5w20. The Vettes have a different performance requirement hence the higher weight oil.

Damn. 0W20.. what a shame. 5W30 used to be good for just about anything except Diesels. I take it they went to that 0W20 crap when the new direct injection thingies came out in 14 for the trucks? Sheesh, have to wonder if that is what is causing the high oil consumption people complain about in DI engines, but I've also heard it's due to the piston rings having to be engineered the way they are to make DI engines work which as a side effect results in more oil consumption vs the non-di engines.

Even 5w30 (thinking Amsoil 5w30 Diesel) was good for a diesel!

 

The 0w20 is for CAFE standard...the thinner something is, the easier is to pump. I think that's also why the sumps are what, 8 quarts now?

 

In a few years, we'll see 0w0 standards to meet EPA regulations.

      Valvoline R&P Fuel System Cleaner

      By Grumpy Bear · Posted

      Guys that read Dizzy's thread know that eons ago after multiple manifold pulls to clear the CCV orifice I converted it to a PCV system with an orifice below it via the valve cover. The blow-by (sticky rings) was so bad it was impossible to keep clean and accumulated water in the oil in the winter when the moisture would freeze in the fresh air side. The PCV functioning mainly as a check valve. I carefully sized the orifice to reproduce the factory values for crankcase pressure at idle.    Well...took a slug of oil to get my attention but the ring seal improvement meant the system was over drafting sucking oil up and out the breather. (V8 guys with orifice systems are nodding their heads). So today I choked it down...allot....to replicate the "just enough to hold a piece of paper on the fresh air side at idle". May still be to much but I'm working with shims at the moment. When I get it sorted I'll make a proper plate and plug. Perhaps using carburetor jets to tune it.    So I guess this means it isn't my imagination.    Dizzy is a pig guys so don't go expecting huge moves in equipment (your equipment) that is in much better shape. A needle valve....lord that just came to me....

      2027 3.0l - ordered

      By Jus Cruisin · Posted

      I had a new engine installed with under 5,000 miles. It shut off coming around a residential street corner and wouldn't restart. Dealer indicated it seized. New one has been fine since with 10,000 miles on the replaced engine. Annoying but I was given a loaner for the 5 weeks it was down. I won't go with the 6.2l gasser so it's 3.0l again. I love the economy and it tows my enclosed car trailer just fine.

      Lesson relearned on basic diagnostics...

      By calgator73 · Posted

      Coming back from towing a car to my daughter in Nashville truck started making a screaming noise from underneath.  Pulled over placed in park and sure enough whining noise from underneath.  Dropped at the dealer fearing new tranny or another front pump/cover replacement.  Service writer said it sounded like the tranny too...  Well $300, new idler and a belt all is good.  Pop the hood and give a listen. lol  Now I'm telling dealers I'm no longer interested in a new truck.

      OIL CONSUMPTION

      By newdude · Posted

      HD uses the 6.6 gas.   Oil consumption while heavy working is considered normal.  1 quart per 100 gallons of fuel is the normal rate above 8600lbs GVWR.  If more than that, it is considered excessive.   They will have to perform an oil consumption test using the guidelines in TSB 03-06-01-023J.     Information on Engine Oil Consumption Guidelines All engines require oil to lubricate and protect the load bearing and internal moving parts from wear including cylinder walls, pistons, and piston rings. When a piston moves down its cylinder, a thin film of oil is left on the cylinder wall. During the combustion process, part of this oil layer is consumed. As a result, varying rates of oil consumption are accepted as normal in all engines. Oil Consumption Oil usage has a direct relationship with the amount of fuel used. The harder an engine works, the more fuel and oil it will use. Therefore, oil usage as a factor of fuel usage is a more accurate indicator of acceptable oil consumption levels than vehicle mileage for vehicles at or above 8600 GVW. The accepted rate of oil consumption for gasoline engines in vehicles at or above 8600 GVW is 1 liter (1 qt) within 400 liters (100 gallons) of fuel used. This rate only applies to vehicles under warranty, maintained in accordance with the appropriate maintenance schedule, driven at legal speeds and within design intent of the vehicle. Many factors can affect an owner's concern with oil consumption. Driving habits and vehicle maintenance vary from owner to owner. Thoroughly evaluate each case before deciding whether the vehicle in question has abnormal engine oil consumption. Gasket and External Leaks Inspect the oil pans, engine covers, and the engine oil cooler for leakage. Inspect for oil leakage into the engine coolant. Improper Reading of the Oil Level Indicator (Dipstick) The vehicle must be parked on a level surface to obtain accurate oil level readings. Verify that the dipstick tube is fully seated in the block. When checking the oil level, make sure the dipstick is wiped clean before taking an oil level reading and fully depress the dipstick until the shoulder bottoms out on the dipstick tube. The dipstick should be the proper part number for the engine/vehicle that is being checked. Not Waiting Long Enough After Running Engine to Check Oil Level The vehicle should be allowed to sit for at least 15 minutes, after the engine has been shut off, before taking an oil level reading to assure the oil has had enough time to drain back into the crankcase. In order to ensure accurate results, the temperature of the oil should be close to the same temperature as the last time the oil level was checked. Improper Oil Fill After an Oil Change Following an oil change, verify that the proper amount and type of oil was put in the engine and that the oil level on the dipstick is not above the full mark or below the add marks. Refer to the Owner's Manual or Service Manual for information on recommended oil quantity, viscosity, and quality. High Speed or High RPM Driving Continuous driving at high speeds/high RPMs may increase oil consumption. Because this may not always be an everyday occurrence, it is hard to determine exactly how much the oil economy will be affected. Towing or Heavy Usage Towing a trailer or hauling additional weight will increase oil consumption. Large frontal area trailers will further increase the work required from the engine, especially at highway speeds, and thus increases the rate of oil consumption. PTO Operation Operation of a PTO will increase fuel and oil usage, as the PTO driven accessory uses engine power to operate. Crankcase Ventilation System Verify that the positive crankcase ventilation (PCV) system is operating properly. Blockages, restrictions, or damage to the PCV system can result in increased oil use. Oil Dilution from Condensation On vehicles that are usually driven short distances, less than 8 km (5 mi), especially in colder weather, condensation generated from cold engine operation may not get hot enough to evaporate out of the oil. When this occurs, the dipstick may indicate that the oil level is over-full. Subsequent driving on a trip of sufficient length to enable normal engine operating temperature for 30 minutes or more, in order to vaporize excess moisture, may give the customer the impression of excessive oil consumption. Engine Temperature If an engine is run at overheated temperatures (see Owner's Manual or Service Manual) for more than brief periods, oil will oxidize at a faster than normal rate. In addition, gaskets may distort, piston rings may stick, and excessive wear may result. Verify that all cooling system components are in proper working order. Engine Wear Piston scuffing, excessive piston-to-wall clearance, tapered or out of round cylinders, worn, damaged or improperly installed valve guides, seals and piston rings will all cause an increase in oil consumption. Measurement of Oil Consumption Engines require a period of time to BREAK IN so that moving parts are properly seated. Therefore, oil economy should not be tested until the vehicle has accumulated at least 6400 km (4000 mi). An exception would be allowed only if an engine is reported to be using more than 0.946 liter (1 qt) in 1600 km (1000 mi).   Verify that the engine has no external leaks. Repair as necessary. Verify that the engine is at normal operating temperature (see Owner's Manual or Service Manual). Park the vehicle on a level surface. Wait at least 15 minutes, after the engine is shut off, before checking the oil level to make sure that most of the oil has had time to drain back into the crankcase. Check the oil level and record the vehicle mileage, date, and exact oil level on the form included in this bulletin. Next ensure the oil level is at, but not above, the full mark on the dipstick. add oil if necessary. Also ensure the proper viscosity and quality oil are being used as recommended in the Owner Manual Ask the customer once they have consumed 100 gallons of fuel schedule an appointment and return to the dealer for inspection. If the final evaluation shows that the engine uses more than 0.946 liter (1 qt) in 379 liters (100 gallons) of fuel used, follow the published symptom diagnostics as described in the appropriate Service Manual. If the oil consumption test shows that the engine uses less than 0.946 liter (1 qt) in 379 liters (100 gallons) of fuel used, explain to the customer that their engine meets the guidelines for oil consumption.
