First oil change on my truck

I just did the first oil change on my truck at 3k miles. I used Castrol GTX 5W30 dyno oil. I was thinking about putting in 10W30 on account of hot summer here in Florida, but I already had two gallons of 5W30 so I stayed with that.

 

As a precaution, I replaced the oil pan drain plug rubber gasket. I am not sure if it is necessary to change it every time, but it is rather pricey (about $ 1.60 from a GM dealer). I noticed that the oil pan is cast aluminum so I was very careful not to overtighten the drain plug. This is the same set up as my motorcycle which also has a cast aluminum oil pan and it is easy to strip the threads in the pan by overtightening.

 

Installed A/C PF46 oil filter and tightened it by hand only. One thing worth mentioning is that I made a mess becuase the oil comes out of that oil pan fast and I missed the oil drain pan by about 4 inches! :cheers:

 

Do you guys replace the oil pan drain plug gasket at every oil change? Do older models have the same rubber gasket? I never owned a vehicle with a gasket like that.

No. Don't worry too much about overtightening the bolt, the head on that plug will strip faster than you can say 'this bolt head is too d**n soft..'

No,You don't need to replace the gasket at every oil change,Heck I never changed the one on my '99,I had almost 100 grand on it and it never leaked.

You mean on my '04? Oh yea,I do the first oil & filter change on all my trucks around 1,000 miles then every 3,000 miles after that.

Even running Mobil1 I still change it every 3,000 miles.

I am kind of like Rich, gotta take care of that baby.

 

I am running Amsoil 5W 30 and do a complete change every 6 months and a filter only with 1 qt add in between at 3 months. I have to go by time because this is my wife's truck and she will only put about 5,000 miles a year on the truck.

 

I have not doubt the oil will go much much longer. However, in speaking with the head technical engineer at Wix, they say a filter is only good for about 5K to 6K and it is maxed out as far as capacity.

 

I am trying to find out if Wix is making the new EA filters by Amsoil which claim a much higher capacity than std filters. I will let you know if I am able to find out for sure.

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      Possible lifter tick after DOD delete

      By davester · Posted

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
