I was wondering what is better: changing your oil by time (ex. every 3 months) or by mileage (ex. every 3000 miles).

 

Also, for those who run synthetic oil, what do you change your oil at?

im perty old school so i go by the 3K miles, or if 3months happens first then ill swap it out then. Also oil color and smell will tell you allot. When i didnt run a speedometer or odometer in my old pick-up i just went by oil color/smell. When it got dark i swapped or when it smelled "burnt" or gassy i swapped it out.

But if you really want to know what the perfect frequency is take a few lube samples. Ask around to see who will sell you the bottle( around here it would be an HD truck shop, like Freightliner KW or Peterbuilt). Then you just fill that little guy up with oil as you drain it (not the first or last bit of oil that drains) you send it in to the address on the bottle and in a few weeks time they tell you more about your oil than you wanted to know (this also works for transmissions, diffs and cooling systems). From that your able to tell if your loosing head gaskets, timing sets, bearings or running the oil too long or not long enough. Last time i ran one i just swiped a sample bottle from my dad (hes a diesel tech and keeps em around) but i think they are around $20.

      2026/2027 Suburban — confirming AS3 bench delete with standard MagRide/Adaptive

      By newdude · Posted

      Here's the 2026 order guide - Vehicle Order Guide   RPO code "AS3"?  Not seeing it.  What is it supposed to be?  I see AS3 used a long time ago as some sort of seat option, but its not applicable to the current Suburban.    I see RPO code "AZ3" which is 1st row 40/20/40 split bench.  That is only on LS trim, which LS can't option any of the trick suspension.     2nd row bench power fold RPO code is "ATT".  So your dealer should be able to sort their locator to find matching builds by searching the combo of ATT and Z95 combined to find a 2nd row power fold with MagRide.     You can do the 2nd row power bench AND have MagRide, or Mag with Air on Z71, RST and High Country.     Here's a Z71 with 2nd row power bench and the Z71 Off Road Package which adds the Adaptive Air and MagRide - 2026 Suburban | Details | Vehicle Locator   Here's an RST with 2nd row power bench and the RST Capability Package, and RST Capability adds the Adaptive Air with Magride - 2026 Suburban | Details | Vehicle Locator   I can't find a High Country, but you can do it on there.  Requires the 6.2, and the Sun and Tow pack which allows you to then option the 2nd row power fold.  Black interior only.  High Country comes standard with MagRide and you can order the air if you get the High Country Deluxe, but Deluxe will take you to captain 2nd row.       You can do it at GMC on the AT4 and the regular Denali (not Ultimate) as well.

      Looking at ordering a '26 WT because I want a std cab, std bed

      By newdude · Posted

      So.  Get this.  On the Chevy regular cab, you can get the factory remote start at the dealer from the accessories catalog.  BUT.  GMC, you can't.   Now...get this...GMC 2 door, you CAN get the power seat.     Go.  Figure.   Anywho.  are you trying to order?  Or locate?  Ordering for 2 door 1/2 tons has been stopped as of April or May?  So you won't be able to order.  You'll have to shop on the ground units or in transit units.     Ordering was stopped because the new trucks are coming.

      Tonneau cover that does not leak water

      By cherryred21duramax · Posted

      Thank you.  I really appreciate the well wishes.  I'm an engineer in the telecom industry, I know hardly anything about marketing.  Over the years I did some videos for nonprofits and web sites for small businesses and the seed was planted.  Agree with over-buying, I started shooting on an iPhone before I got my first DSLR and tripod.   I'm looking at trucks with potentially 150,000+ miles to keep the cost of entry low while focusing on the client experience and equipment.  Good wireless mics for interviews, the right lenses & lighting to look professional.  But I don't want to be late or break down, the stress of emptying a trailer & securing a rental truck right before a gig would negate any savings from buying a junker.  So anything that leaks water, has extensive rust, or generally unreliable I'd like to avoid.   Does GM/Chevy overbuild these trucks for upfitting?  I talked to a local upfitter, they sometimes tie lights & other 12V into existing circuits, which I always thought was bad.  Which is why I enjoyed the AUX upfit switches on previous trucks (odd they mostly come with off-road or work truck packages).

      i guess it might be depending on the type of driving. my 2.7 has 120k miles, changed the plugs at 70k and it runs as good as new. i have not used any injector cleaner

      GM's are stainless and have a fairly robust powder coating, although, still not worth $850 in my opinion. They will hold up a lot better than their cheaper steel aftermarket counterparts.   What I like about the GM step bars is dealers will often equip their dealer stock with them. Lots of margin. Which means a lot of people end up buying them because they're already on the truck, even if they don't like them. So it's pretty easy to find brand new takeoffs with hardware on Marketplace and Craigslist for about $250.   That's what I did for my crew cab. I wanted ZR2 rock rails for the look, but with the ability to bolt up GM's assist step package. From GM it's about a $2500 accessory all in. The old folks in my life can't get in the truck without steps. I found the whole package on marketplace for $180.
