Add engine oil!!!

I dropped quite a bit more oil life percentage during the 9 day stay than I did during the 19 hour drive, due to much more frequent key on/off cycles.

We returned back home 2 weeks ago after about 2,600 miles total. I'll have to get the current oil life percentage tomorrow, but I know for certain that I left our area with 45%.

You're right, that is a long drive, but by driving straight through there and back, we essentially had 2 more full days in the area for our vacation which was great, other than sitting around in a hotel room out on the road with nothing to do except sleep.

I should also mention that we departed on a Friday evening at 6:00 PM after I was up all day since morning, which wasn't ideal. The return trip was a lot better by waking up at 4:00 AM and hitting the road 5:00 AM after being fully refreshed after a full night's rest.

I took a 1,150 mile road trip earlier this month, driving 19 hours straight only turning the motor off for fuel ups, rest stops, and a 2 hour nap. Oil life indicator only lost 1% during that whole time from 45% to 44%.

But did you actually check the oil? That would be more telling.

Full before and after on the stick. About 56,000 miles on the truck.

Current percentage is 33%. So at nearly 3,000 miles of driving the oil life remaining percentage only dropped 2%. I'd also wager it was less than 2% as it was likely at 35% for awhile before we left on our round trip road trip.

I just noticed - today's oil life percentage was 32%. And I started this thread at 45%, in which it only decreased by 2% to 43% after a 2,600-2,700 mile trip. But now it's at 32%. So it seems if you drive the truck continually, it will drop slower than if you take short trips around town. It's definitely not based on time alone or mileage alone. I wonder what the actual formula is?

That kind of makes sense. The algorithm used must take into account long trips, short trips, stop and go, etc. etc. So yeah, that makes sense to me. Wouldn't it be nice if they had an actual sensor monitoring the oil quality? Contaminants, etc etc.... That would be so cool and probably save a ton of oil if the computer knew exactly how your oil is doing. Not an algorithm, a true test of the oil. Now that would be very cool!!! But that might put a few oil companies out of business with less demand for their products....And we can't have that can we....lol

Now that would be complicated. A Blackstone Laboratory in every engine, conducting an oil analysis every 0.826 seconds!

Bklabs doesn't even use FTIR and that technology is what you need to do exactly what you boys are thinking about. Its possible but IR, near IR, or Ramen sensors are not durable enough/cheap enough to stand the heat yet. Trust me I worked on it for 30 years.

GM Dr's Don Smolenski and Shirely Schwartz developed a bunch of different models for GM and after testing Chemical Reactor model, Volume effects, Average oil life, Chemical Kinetics, Oil Film Surface Area vs # of Combustion events, Severity of Service models....... They settled on Severity of Service ( DSC generated OXIDATION temp curves) adjusted for Volume and Combustion events model. That backed up by Engine Servicing model so its on a end stage timer to save their bacon if the mathematical algorthim goes too far. Direct sensing of temps has been added in recent years to tighten up the mathmatical model. THE BOTTOM LINE IS WE HAVE A GOOD GUESS with these models but its not direct sensing.

So I had an idea concerning oil monitoring. Why is that so much of a stretch for technology these days? We have cars that drive themselves...Seems to me the money and technology for something like that is way higher than an oil monitoring sensor. I mean why not? If you could get say 15 or even 20k miles out of your oil with a sensor knowing when it's going bad or has too much iron or whatever else in it....wouldn't that save a ton of money and oil usage? Why isn't that possible in the days we are living in. Hell I have a phone that knows exactly what I'm saying and knows exactly where I am at all times. The technology has to be there...and I think it would be super cool if our vehicles would tell us that.

"They" want to create machines with no oil at all, so, they don't care about that.

And that is a very valid point!

Hey customboss, what if the oil flowed through a tiny tube so a sensor could figure how thick it was. Would that be ‘nuf info to cross reference remaining life?

It’s been done manually. Amsoil oils has advertised extended for decades. I’ve seen them used in hundreds of vehicles and equipment. We’ve had remote filters we could pull oil out for testing. My brother went 50K miles on Amsoil in his 95 Big Daddy dodge truck. My 94 Z-28 Camaro had 5 oil changes in 130K miles. I can give more examples you get the idea. Here’s the rub. Engines have changed. If you’re constantly cruising the highway you can go father with oil than in town driving. As far as automobiles sensors that’s already done. It’s assuming you’re using the correct clean oil and senses your driving tells you when to change. As much experience I’ve had with extended and with no issues I don’t do it anymore. Not to that extreme. Definitely not with transmissions. Oil is cheap engines aren’t. Follow the extreme service schedule. You’ll be covered. I think you know that and you’re spit balling. It just isn’t worth it for most people.
