My free oil changes is up, its time to start changing it myself.

What's everyone's oil of choice on these beast of burdens?

I do a fare amount of idling especially during the hot summer months.

Other than that a mix of city stop and go and highway.

Anything with Dexos1 spec...

This, although my personal preference is for the Pennzoil Platinum line. Mobil 1 Advanced Fuel Economy is also putting up some impressive used oil analysis results on BITOG on these engines.

Any name brand that meets the specs and you can't go wrong. Most people have a personal preference

Thanks everyone and a howdy neighbor! to Retired Bob also from Charleston SC!

Mobil 1 is what I used to use on other trucks, I guess I will continue with them!

 

Next question is which brand oil filter? I'm going to search for the article about test results on the different brands of filters. I will post it here if I find it.

Mobil 1 from Walmart for $25 per 5 quart jug combined with $12 rebate from Mobil (https://mobiloil.com/en/promotion/mobil-promotions/up-to-15-dollars-off-with-mobil-1-and-mobil-super). Walmart isn't on the participating retailer list but I have gotten the rebate 4 times now (along with members on the BITOG forum).

Well the website only states that list as being "SOME" participating stores and does not list Walmart as you had said. I went ahead and submitted my info for (2) 5 quart mobile 1 purchases from Walmart at 12 bucks rebate each to see what happens. I certainly appreciate the money saving tip brother. I like a a lot of others, are now out of the free dealer oil changes so we have to figure out how to get this done. I bought the K+N filter cuz it looks good and was actually in a sealed plastic sleeve inside the box. Going to have to research that choice now to though, hopefully i will run across a rebate there too LOL

As stated above, anything that meets the dexos1™ specification and you will be fine. Most can find good deals on oil at their local Walmart.

    • 87 down as low as $5.14 here... winning!
    • Progress... sort of.   Intake is disassembled, spider is out, fuel lines removed. Used a torch on the stripped screw with the lower intake off, much easier when I've got the intake sitting on my workbench, I made it talk. Walked right out with a pair of vice grips once it was nice and toasty hot.   New parts are piling up on my service cart waiting to be installed. Distributor, temperature sensor, new gaskets, fuel line kit, themostat, water neck.   My new pickle is I don't want to spend $600 on a replacement spider. I'm not sure IT is bad. I'm probably splitting hairs. Or it's $300 to send mine away and another 3 weeks of the truck just sitting. I have half a mind to assemble everything with the old spider to see if I can get away with just replacing the fuel pressure regulator to be safe. The obvious issue was the gushing high pressure fuel line which will be replaced. Getting to the spider really isn't that hard, and now I know what I'm doing , swapping it would be a breeze should it absolutely need one. Stupid, or smart?   The part that gives me pause is replacing the distributor. Well, it's already out. And I didn't mark it, whoopsie! Engine was at TDC when I removed it, I know that, so upon correct reinstall the metal tip on the rotor should point to the TDC mark on the distributor because that's where it was pointing on the old distributor. Worst case I'm a tooth off and have to re-stab it.   But then, what? I assume the truck will start. It doesn't appear the timing can be set. Here's the problem: These distributors can't be rotated but a degree or two, by design. What I read is Cam ****** needs to be -2 to +2 degrees, ideally at 0 (and checked/set above 1000 rpm). There should be enough wiggle to get that properly set, but checking the reported value is another potential issue. My Actron 9185 scanner says it supports enhanced GM PIDs and Cam ****** is one of them but it's unclear that I'll be able to correctly see it over OBD 1.5. I can see why people end up junking these things with life left in them. They're an absolute nightmare with tweener-year diagnostics/electronics and unobtanium parts.   Fingers crossed it starts and idles nicely. There can be hope, right? I'ma buy a lottery ticket the same day just in case.   Next steps..DO IT. I have not installed an intake before so I've been reading and watching a lot. Some say NO RTV except on china walls, some say DO RTV on water ports but not fuel/air intake. 1/4 or 3/8 bead on China walls? I think my strategy will be, obviously, RTV china walls with overlap on the gasket corners. Chapstick-style RTV the water ports. Leave intake ports dry. The only set of intake gaskets I could find locally are Edelbrock performance gaskets (uh...for an asthmatic 190hp V6? LOL) so we'll see how they do.   #NoToolLeftBehind. It took an hour, but my recovery mission for my deep 10mm socket was successful. It had rolled down the bellhousing and wedged itself between what I think are the fuel lines? I couldn't see it at all, but with a junk antenna I had laying around, I blindly went poking/sweeping for it, heard it clink, raised the truck, and caught a sliver glimpse of chrome with a flashlight way up there in Narnia. I had pushed it farther along the lines holding it captive, but within access of severely improvised tools, poking and cursing at it to finally knock it free to where I could get a fingertip on it to bring it home.    Not much to see.
