Learned something new

Truck gets an oil change whenever I feel like it/have time usually between 18,000 and 25,000 miles. Typically uses 1-2 quarts over that time. Gets a full oil analysis at every oil change, oil is still good at every change; soot, fuel/antifreeze contaminant, flash point, oil grade, heavy metals and trace metals all within specs and no changes. Currently setting at 355k miles, expect it to last another 300k easily.

 

Nice. I use oil analysis for drain intervals as well. I got away from it for several years but started again in the last couple years.

 

Sure, pure speculation because I haven't bothered to have oil analysis done on any. Kinda like how I say that unless you have a moisture meter, you'll never know the actual MC of wood.

That said, aside from that old sea and snow citgo oil, I don't have any oil that is older than 3 years old, and I only have a couple of 3 oz Stihl grey oil left that came with my ms170 I won at Denny's. Those work fine as I've been using them especially after this oil thread.

 

I'll defer to that expert, who's job is actually oil. I'm not an oil hoarder though and that old sea and snow oil will get used in an older oil injected sled, outboard, or premix for something like that. Not air cooled power tools though.

 

Last I checked an oil analysis was almost as expensive as the oil change so I’ll personally just continue to change at 4-5000 miles with a good filter.

 

The coyote tuner / expert I follow says to simply change the oil every 8k with full synthetic and there's not much to worry about. I'll stick to that like I have. Just changed my oil on my truck a couple of weeks ago. I'll be good until next summer/ fall at the rate I put miles on the truck.

 

It can be depending on the cost of the oil but if you can extend your interval double or tripple, is works out in your favor. Plus it can show problems you weren't aware of like our hrv making oil. If you are someone trading in something every 100,000 miles to avoid known issues or because you have to have new all the time, then you might as well run walmart supertech and filters.

 

Oil sample kit from caterpillar is $9 each last time I bought them. Includes the mailer for it as well.

I change my oil every 10Kish miles. The truck reminds me. After two years, it’s still not using any oil now at 20,000 miles.

2023 F150 5.0 Coyote FlexFuel. Got it specifically for the flex fuel feature.

 

I’m not sure how many are aware of the multiple levels that exist in the STLE certification realm. I’m pretty sure by the answers, banter, and opinions offered here not many know. That said, condition of lubricant, condition of machinery the lubricant is being used in, condition of new lubricant, condition of lubrication program, and finally correct lubricant sampling just to name a few. I honestly don’t care about debating anyone about oil, it’s almost as stupid as debating someone that a Stihl is better than a Husky. I do care about debates being carried out without merit, which we refer those as being opinions.

 

I got my exposure due to the US Army training on their AOAP. Used the caterpillar fluid testing program and their training as well.

not saying I’m the definitive expert, but I’m not the Joe blow off the street either.

that at least has taught me enough to stay away from the Bob the oil guy website and with $10, can get a fancy cup of coffee.

 

STLE recognizes neither the minimal U.S. Army AOAP program or Bob is the oil guy standards. For reference, I was in the Army, there is a reason there is a single sample acquisition standard, and yeah the internets…

 

Tell me more though, I’m intrigued to say the least.

 

Your the definitive expert …

your right.

 

Funny how this has snowballed. Op asked if oil can go bad. I posted the testing vids showing that it does with explanations of why. This by a certified tribologist, who is also a certified oil analyst, one of only 300 people in the world to hold both, yet the debate rages on. If that guy isn't expert enough for the naysayers then so be it. Lol.

 

Oh no I’m by far not an expert, but you reading the internet and you being aware of the AOAP program doesn’t make you one either. I will wager that I have been to 1 more STLE school than you have been to.

 

Yep. The oil change reminder is really nice in these and easy to use. You will be better off changing the oil at 8k since it's a coyote. Mostly for the chain guides I believe . Sure, if you never tow and it's 2wd, maybe the 10k would be fine, but 8k is a good figure. When you tow, the reminder will adjust to have you change the oil earlier.

 

Absolutely, but after a while opinions are backed up by results.

 

like I said, my training has been enough to keep me OFF the Bob the oil guy website ..

And WITH a $10 bill will get me a fancy cup of coffee.

why are you attacking me?

so long as my ASE oil weight and API meets the manufacturer specifications, I’m happy. Design programs with way more funds than my abilities have made those determinations that I don’t really need to shade tree the requirements.

 

I don't doubt oil can go bad, but over yet to experience it so far. I also don't push it to get to that point.

Yes, Grandpa's old tin can of snowmobile oil from the 60's or early 70's is still full. I won't even think about cracking that crap open because oil has gotten so much better over the decades.

Edit, there's also the issue of Internet shills, which will sell out their titles and their notoriety to make money. You always have to question the source and their motives. Just like some dealers saying the oil changes should be done at 5k, or less, when the vehicle is designed to go longer intervals.

 

When challenged, you deflect.

FHC, this is where I apologize before I get banded. Many of you know me, I’m all about saws, fraternity, and especially passing a good time, this isn’t me, but when I see bs I call it.

I’m not attacking you, I’m attacking your uneducated opinion presented as some kind of fact. When I or my company pays for a school or certification program, it means there is at least some basis of merit.

Good day sir.
