  1. Drivetrain noise just developed

    Do you only hear it while accelerating in auto or 4 hi? My Sierra has done that for quite some time (even after a front axle and T-case fluid change).
  2. Battery life

    Still on the OEM battery in my Sierra and it cranks/starts just fine. Truck was built in August/September 2013 and now has 142,000 miles on it. I live in a cooler climate which seems to be easier on batteries.
  3. "The Silverado 2.7L will be rated at 23 MPG Highway." Seems low. The 2019 5.3L V8 2WD is rated at 23 MPG highway.
  4. Here are two filters that I have cut open: Fram Ultra XG10575: https://www.bobistheoilguy.com/forums/ubbthreads.php/topics/3534172/Cut_open:_Used_Fram_Ultra_XG10 Mobil 1 M212-A: https://bobistheoilguy.com/forums/ubbthreads.php/topics/4580584/Cut_open:_Mobil_1_M212-A_used_ I thought both were constructed well but I like the media in the Fram Ultra better (more robust). As some of you may now, GM changed their bypass specs for the Gen5 motors (now 22PSI). From what I have gathered the Mobil filter meets these specs but the Fram does not (9-15 PSI). I read that Fram will be releasing an updated filter with higher bypass at some point.
  5. I don't believe there really is a "best" oil. Too many variables. For general purpose street use there are plenty of good oils out there that will perform well. If you have a 2018 I assume you still have powertrain warranty. A Dexos1 certified 0W-20 is all you really need. I have been using Mobil 1 since I had my last oil change done by the dealer as part of the included maintenance. I'm now at 142,000 miles. Engine runs good and oil consumption is minimum (1/2-3/4 qt every oil change which is around 7300 miles). My primary reason for using Mobil 1 is due to price. They usually have a $12 rebate on 5 quart jugs every spring and fall. They will accept Walmart purchases even though they don't list them as a participating retailer. After rebate a 5 quart jug comes out to around $13 which is hard to beat. They also offer a $17 rebate if you purchase a Mobil 1 oil filter also. This is the filter I have been using lately (M1-212A). This promotion is still going on (ends October 31st): https://mobiloil.com/en/promotion/mobil-promotions/synthetic-motor-oil-coupon
  6. Oil consumption

    Been on a pretty steady diet of Mobil 1 0W-20. I currently have 142,000 miles on my Sierra and AFM has been disabled since around 90,000 miles. I really didn't notice much difference in oil consumption after disabling AFM. I'm now on my 2nd OCI with Mobil 1 5W-30. Consumption seems to be about the same.
  7. Oil consumption

    Has anyone experienced this much consumption? I burn around 1/2-3/4 of a quart between changes (usually around 7300 miles).
  8. For it's size the 3.0L Duramax puts out some pretty good numbers compared to it's big brother 6.6L Duramax. If the 3.0L Duramax has 282 HP and 450 lb-ft torque that would equate to 94 HP and 150 lb-ft per liter. The 6.6L L5P Duramax has 445 HP and 910 lb-ft of torque which equates to 67 HP and 138 lb-ft or torque per liter. Appears the 3.0L is doing more with less.
  9. Oil change intervals

    For sure. I think it will be at least a few weeks but I plan to remove the TB and clean it as it's been awhile. I have one of those USB endoscopes that hook to your phone. I'll see if I can get it to snake through the intake manifold and down to the ports. I have 142,000 miles on my 5.3 with a catch can on since about 21,000 miles.
  10. UPF48R

    I would think (in theory) if an oil filter caused oil pressure to increase that would be due to more restriction.
  11. Oil change intervals

    Thanks. Might have to try this on my Sierra.
  12. Oil change intervals

    I'm just curious how you did that? Endoscope camera?
  13. Falken Wildpeak AT3

    I have P275/60R20 and have been running 35 PSI front and 32 rear. Wear has been good and even. I have found with previous tires that too much air in the back the tread in the center wears a lot quicker (my bed is usually empty).
  14. I got 1.25" lift on 3rd setting
  15. 2015 1500 50k mile service

    I removed the bolts that attach the transfer case to the crossmember. Was then able to jack it up a little and put a wedge under it. This raises the transmission a little. I also used a ratchet strap to pull down on the exhaust. I did this by putting a jack stand under the frame with a 2x8 under the stand. The 2x8 was on the floor and ran towards the exhaust. This gave me a point to wrap the ratchet strap from the exhaust down to the 2x8. Putting a little tension on the strap pulled the exhaust down a little. Doing both of these gave me enough room to remove the transmission pan. This guy did something similar: https://www.silveradosierra.com/how-to-articles/how-to-pan-drop-and-filter-change-on-gmt900-4x4-six-speed-t442161.html
