I would stick with 5w-30 if that's what it factory recommends (assume that's what all 5.3s ran). As far as oil that your guess is as good as mine kinda thing. In all my vehicles in the past I just used conventional Valvoline and changed it ever 3-4k with a decent (not fram) filter and I haven't had any issues at all.

 

That being said I just got my first brand new vehicle and I will be putting Mobil 1 in this weekend.

 

Plugs and wires - with your mods i'd run with ac delco wires and plugs again. Lasted ya this long with out any trouble, why not go with them again for the next 100k

Stick with 5w-30 and the brand you like. Plug wires, get the lowest OHM wires you can afford and iridium spark plugs. I put some Taylor wires in mine that I bought from Summitracing.com I think they were under 50 ohms per foot and cost less than $70. I did notice the power and mpg pick up.

      Transmission Woes :-(

      I wonder as well, why they would send me a text message with links to these suggested procedures totalling over $10,000 without even the slightest hint of how they arrived at these being necessary.

      OCI, not when but why?

      By Grumpy Bear · Posted

      https://precisionlubrication.com/articles/oil-filter-efficiency/     For them it is a problem of $$$$ and compliance. To cover both they have to lie from the heart.    Government wants low waste oil numbers so the bar needs to be very low on contamination to met that requirement.  Consumer wants cheap maintenance (perceived cost). Again requiring a low bar.  OEM wants high margins at a cost effective warranty rate and lots of repeat customers. More low bar.  Filter manufacture wants the same thing the OEM wants. See the pattern?   Consumers are fickle and also want perfection requiring a HIGH bar. Inconsistent with all of the above. Consumers can be, when the put their minds to it, inquisitive, love winning arguments which requires some useful information to be available to support them. And this is where it gets sticky and the lies begin.    Information needs a solid well grounded point of reference if we are to compare in a useful way. There is a standard for this.  ISO 4548-12. This standard sets the particle size at a specific Beta ratio and darn few are faithful to its intent.    If they don't state the test method they change the particle size or the Beta ratio to hit a perceived favorable standard. They obscure the information in a way as to prevent direct comparisons leaving the consumer with one method. UOA's with an ISO 4406 test result. Pricey and not allot of labs willing to do the work. Lobby work happens everywhere, not just at the seat of government.

      IF,IF,IF. If they cared about quality instead of profit and this applies to any company, what a concept.

      2001 GMC Sierra - Banging feeling in steering wheel

      By Christopher Miller · Posted

      Good Morning Gents..hope everyone is enjoying a beautiful saturday morning. I have a 2001 GMC Sierra that I bought used in 2018. I am the 2nd owner and its a beautiful truck. Ive put about 60,000 miles on it and recently the front end has felt funny. Kind of loose when hitting bumps adn sometimes I actually feel a "bang" in the steering wheel. I took it to a local guy who said that everything was tight and he tightened the steering box. It didnt feel much better, so I had him replace the front shocks, which had noto been done since I bought it. It had the check enging light on so I took it into a local garage to fix that and check out the suspension. Everything is original and the rubber bushings that I can see look bad. They said everything was tight and there wasnt any play in the front end. Im concerned about the banging feeling in the wheel. Ive been driving this truck for 8 years, so I know how it usually feels and this is something new. Its a second vehicle, so I dont drive it all the time, but Im trying to use it more often. I live out in the country and some of the  roads are kind of rough and I alive on gravel roads. Anyone deal with anything like this before?

      Yes of course. There’s no experience in the Trump organization in hiring contractors. it’s not like they’re experienced in that field.😆
