  1. So Walmart has the QS Ultimate for $17.97 for 5 gallons. The eight quarts would then be $28.75 and i think about $12 for the filter. So $45 would cover the taxes on the filter and oil. I spent so much on the truck... i consider the oil change to be insignificant. I also changed the air filter to a 99% from the factory 98%. This helps with oil changes as you can keep the particles out of the engine in the first place. The mobil 1 filter has a 99% efficiency of removing 30 micron or larger. Someday i am going to install a two stage filter on the thing like it ought to have. I bought a drain plug with a real magnet on it. The factory on mine did not have one... https://www.amazon.com/gp/product/B07G8QDZK8/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1 I have rebuilt plenty engines.. with the magnet you can see the knock on the drain plug well before you can hear it.. ==pete
  2. 8 quarts... when i get around to it but less than 5,000 miles. The key is to have a large magnet on the drain plug.. so you can see what iron is captured and use the M1 filter as it is 5 microns tighter.. i think 20 versus 25 microns.
  3. 5W30 Quaker State Ultimate Durability... $19 bucks for 5 quarts... about $30 for the change.. Mobil 1 212A filter... about $12. It takes me about 20 minutes... So far very happy with my Sierra... I run the 5W30 and have the AFM disabled... i don't trust it.. i would rather have oil with a little body to it... 0W is probably just fine.. but my other engines don't use it... and i like keeping it simple... Comparing the 2018 aluminum block 5.3 to my earlier '05 iron 5.3.. i think GM has gotten the piston slap under control from the mid 2000s. i imagine that the iron inserts in the aluminum block result in improved clearance specs.. these 5.3s are really Y-block engines. they are nice and meaty with the block extending way past the crank centerline. My F150 had plastic valve covers and a plastic oil pan. GM has a more industrial engine with die cast aluminum covers on the heads and oil pan.. i think it will hold oil in a lot better than my Ford 2.7 did... here is to hoping.
  4. Toyota? My 2010 had cam phasors that sounded like thor under the hood.. The Tacoma was a pale ghost of my '90s boxed frame toyotas... and 22R... for reliability. Had a Ferd 2017 2.7 Lariat. 4 oil pans and one blown radiator. No more turbos for me thanks. Bought a leftover Sierra '18. It is heavier than the other two.. but it gets better mileage. My 05 Yukon (5.3) only needed a water pump to 100k. Ram, Ferd and GM are very competitive. My finding is that it is best to avoid turbo charged motors for daily drivers.
  5. I am thinking... take the belt off the pump.. but leave it on the block. Re-plumb as the author indicates.. the pump is there to use if you do sell or remove the AFM delete...
  6. I had the same thing happen to me on a Tacoma... on a free dealer oil change. Luckily the oil blew on the windshield and i caught it within a few days. Still a mess. The staff that changes the oil.. are not the trained techs.. that you pay a hundred bucks an hour for. I am not sure what the optimal solution is, as everyone has different capabilities, tools and time. I change my own oil... i would probably pull the engine if i needed to. I personally do not think it a dealer issue either. It is a generational issue at its core. Care and pride in the work is sorely missing in young people today.
  7. I have had trucks and jeeps a long time... i think there will be an election where the "in" party does fierce things to energy - like carbon taxing - and we have a couple dollar tax on each gallon to deter us pickup owners from having trucks.. and build out infrastructure for the cities, so they can have public transportation as they are transported under the ever watchful eye of millions of cameras... I am hopeful we can have cars in twenty years.. uber and the condition of the roads is also against us..
  8. I think the interior is an important item.. but reliability is a vital item. that is, coming from a '17 F150 eco to a GMC has been a real reprieve. I agree that one may buy a truck based on its looks or interior. But you will sure as hell get rid of it on account of an unreliable power train. And that my friends is where you get bit. Pete
  9. I have 27+ mpg run on my 5.3 6sp too. My last 5.3 was an iron block 2005 in a yukon.. and you could not get more than 19+ mpg no matter how you drove.. Bravo!! Magnificent progress with higher compression, VVT and direct injection.
  10. I purged a '17 F150.. Based on that experience I got an '18 Sierra. They look better than the '19s overall either the chevy or gmc. Looks aren't everything. I did the 6 sp and 5.3. I want to turn the key and go. Every-time. '19s... i'd pick the GMC...
  11. Not so sure about toyota.. my last one (2011) had a bad cam phasor at 62k miles. And my F150 blew oil out of the pan gasket and popped its radiator wide open. Anything you use, will wear out. I did the AFM defeat, so i may not have your cam/lifter risks.. but you have some miles on that truck, and you will have to do some maintenance.
  12. As GM Sierra owner... its machts nichts.. as a GM stockholder, i am disgusted. The board is reckless awarding pay at that scale in a business that is competitive as it is. You simply can't be doing a great job as a CEO and have strikes going on threatening the business..The strikes are indicators of problems in the business. Again, the board supervision of the CEO is questionable. As a comparison, Microsoft's CEO is worth 300xs the worker bee pay. You ever hear of a MSFT strike or bankruptcy? ...
  13. I have little difference in mpg under normal conditions. It has run my battery down once, though, when i was out of town for ten days.
  14. I had a 2005 5.3 and you had to baby it to get 18 mpg. My 2018 will get 24 if you do that same drill. GM did it by improving efficiency and power by raising compression... along with variable timing and combustion chamber improvements. They also went from iron to al on the blocks which dropped a little weight. My 2017 2.7 Ferd got 23.5 mpg. The ford has a little lower compression ratio.. four times the cams, two turbos and a lot of single points of failure that the GM does not have... The ford is AL and a little taller in the wind.. There is still plenty of life left in the basic architecture of theV6/8. Batteries and emissions will get it... unless an achates engine comes out of left field.
  15. This is 6k miles with QS ultimate durability... if you see my pic, there is hardly any metal... and very small minute particles. Engine has 7k on it. The 5.3 is a V8 and you are going to have some metal.... bigger pieces = bigger problems. another item i might check is the "sound" that is, you can do some vibration analysis and tell from the frequency.. like is the noise half the rpm, a quarter and so and figure out what the source is.. like a crank, a lifter, or a cam. the iphone app is named vibration analysis. good luck.
