Oil change by mileage? Or by oil life %?

5k miles with Mobil 1 0W20. Likely overkill, there's typically 20-30% left but it's an easy interval to remember... helps me rotate the tires on schedule and it's cheap insurance.

I would happily sell any of my vehicles to someone I cared about.  None of them have been poorly maintained and certainly none have been maintained less than manufacturer recommendations.  But the main reason I say this is that I am very easy on a car.  I don’t drive it hard, I pay attention to things like pot holes, I keep it clean (especially by not eating in my car), I fix anything that goes wrong immediately and have never had a problem.  I say this not to be defensive but to say that buying a used car has more to do with how a car has been treated (respected) more than maintaining it at a level that exceeds manufacturer recommendations.

 

My daughter and a brother in law are so hard on everything they own that I’d never buy anything used from them.

Understood. Hopefully you will understand this with as much ease.

 

From the outside and from a stranger I have absolutely no way of telling the difference.

Understood. That’s why I’d probably never buy used unless it was from someone a had knowledge of how the car was treated.  Of course, as you indicated, 20K and 2 years may work best.  It would still be under warranty and you could still put an extended warranty on it.

3k or a little after no question about it here. Been that way since i started working on cars. Besides I can't follow what man says on a bottle, book, or tv.

If you can't trust man how can you trust man made things? Words by SnowCamo...

A few of these oil companies market the 5k plus oil changes because it gives time for the"detergent" to "clean" the engine. Ok. Uh no... Not buying it. Never will. Doesn't make sense. Why? Do you put lotion and soap on at the same time? Then why would anyone assume doing the same for an engine is ok?

Absolutely agree with you.
I’ve seen someone mix Purrell and Hand lotion and actually wasn’t bad, lol

Results of all my collected data on Pepper. Those records show I change at:

 

1.) 5,000 miles

2) 122.43 hours (between the 167 and 83 hours of Wintersun) 

3) 184.62 gallons (pretty close to the 200 gallon mark DYIER2)

4.) 33 percent OLM

 

I average

27.1 mpg

40.83 mph 

 

I could then change at 45% OLM, 100 hours using 150 gallons at an average OCI of 4083 miles. Changing on gallons would compensate for temperatures and loads effect on the oil. Last UOA's suggested my 5,000 was stretching the limits a bit for my driving style anyway. 

 

Winter to summer 3750 miles to 4500 miles OCI based on seasonal mpg and 150 gallons.

Well...I had my first one at 2200 miles because it was getting darker at an exponentially faster rate than on a vehicle that is "broke in" and will do the second at 5K and every 5K from there on out. Tire rotations too (I did not rotate at the 2200 mile oil change) every oil change. Now, just gonna throw this out there but I get a pretty good look at the oil (color or abnormalities) every time I empty my catch can...just sayin, it's just another check point and since I use a clear glass container, it would also let me see any shiny particles if God forbid it ever started to grenade. No, this doesn't replace a UOA but it sure can't hurt. This is just 100 miles on oil that has a tick more than 1500 on it.

Understandable comment. However, go to the vehicle build section and check out Grumpy Bears 2015 Silverado 2WD thread. Long thread but all the details on changes are there and mileage data that is extensive.

You'll pick the flag up when your done I suspect.

Oil color doesn’t necessarily mean anything. Oil can be very, very dark (black even) and still be effective so diagnosing oil by color is never going to be an exact science.  Some additives in designed into the oil  can cause it to darken quickly.

How do you drive? Baby it or with authority? Properly "breaking in" (seating piston rings) is driven with authority. Just asking.

I change at 5000 mile intervals, oil and filter and set air pressures. When I see the truck rolling up to the next 5k number on the odometer, I know it's time to buy oil and filter. Every 10k I rotate tires. Every 20k, I pull a gallon of trans fluid and replace with a fresh gallon. Change the trans filter every 50k. Diff got changed at 60k.

      2027 GMC Sierra: Official Discussion

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.

      Disconnecting Battery

      By davester · Posted

      If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.

      Disconnecting Battery

      By davester · Posted

      It's just useful to disconnect the battery to prevent odd shorting out when unplugging/plugging stuff together.  I also  touch the two cable ends together (after disonnecting) to drain the small amount of stored battery energy in various modules.   I believe the main system where you need to be more concerned with, so you need to do the above and then wait some time, iss when you are working on the air bag system, to prevent inadvertent firing of the air bags.   The in-cab switches are just that, plain switches, it's generally not a problem to swap them in/out.  For my '12, I'll get an error message on the dash if I power up the truck w them unplugged, but that's it (power up= turn the ignition on).   The ITBC located above the spare tire is a computer that manages the trailer brake system.  That is probably more important to have the battery disconnected.  It does have to be programmed to the truck, either before or after it's installed, for it to work.  For my '12, I had a very hard time reinstalling the main connector to it (IDK if yours is the same or not), it turned out the silicon seal was jamming up, preventing it from going on all the way.  I finally got it fully installed by lubing the seal with a bit of dielectric grease, then it slid on and latched in place easily.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      JR ! I just got the truck back from the Dealership today . The technician did a cold remote start on the truck this morning and it made the noise . It was determined that it was a starter issue and replaced it under warranty . Of course   it did not make the sound after a new starter was put in because the truck was not cold . We will we see what happens tomorrow morning when I start the truck cold  . Keep tuned !   Oh I found a video on YouTube of a cold start and it did the same thing your truck and mine do , I will see if I can find it and post it up
