They're usually incredibly conservative and based on a lot of guesswork from engine data rather than actual sampling of the oil.
Ryder Gray
Drops 10% per week because you put a fram filter on it.
Leo Watson
I can tell this is going to be a full thread about when is best to change your oil lmao. I've never seen one of those monitors and don't know how they would work, maybe it runs off of oil pressure + viscosity somehow. I change my oil every 3000kms or 3 months which is a bit much, but your monitor seems to be working well enough.
Matthew Anderson
Are you driving it hard or in a lot of stop and go traffic? The computer takes that into account when deciding how much oil life you have left.
I'd still get a Blackstone oil analysis and go by what they say though. My car doesn't have an oil life monitor but they said 5k on Castrol edge high mileage with a Wix XP filter, so that's what I'm gonna do.
Landon Ramirez
I redline it maybe once a day and I'm in a bit of stop and go traffic, but I'm also not very hard on the car because I still manage to get 27mpg which is above what the car is rated for. The car is warmed up the entire day, but I stop and start the car probably 20-30x a day.
Joseph Garcia
>3000kms
Nigga are you crazy? Modern synthetic blend oil is good up to 5 times that.
Elijah Lewis
idk if I can trust mine. I do it every 5k which doesn't say much since the car only has 18k miles on it currently. Using full synthetic. I could probably do 10k and quit being an idiot.
Jordan Anderson
I am concerned for my mercedes I do it by the intervals but it's close to 10,000mi but I put redline in should I change it?
Nicholas Rodriguez
Because of amazing german engineering, my car doesn't have a dipstick. The onboard instruments on my BMW are actually pretty accurate according to the mechanics.
Jayden Russell
Only some newer cars use sensors that actually analyze the oil. Otherwise it's literally just a timer.
Ryder Davis
I just use cheap shit I buy in 5gal buckets for ~70. Even with the amount of times I change the oil it only costs about $2000 throughout the life of the vehicle. I do own multiple vehicle so a few of them reach 3 months before the 3000km.
Blake Mitchell
>fram filter Holy shit how did it last 2400 miles?
Zachary Gutierrez
>stops and starts car 20-30x a day Unless it has that auto stop start bullshit why would you do this??
Easton Harris
because I'm delivering pizza and people take like 5 minutes to come to the fucking door every time I leave my car idling, or it simply isn't an option because I have to go too far on foot and someone will steal my accord

Please change that thing. It's for your own good.
Charles Cooper
FRAM Ultra is a god tier filter with a metal mesh inside and excellent filter rate along with one of the best cold start oil pressures. It's not the same as the orange cans of death.
Charles Russell
Get a second key made and lock the door when you're out.
Sebastian Flores
It's still worse to have the car idling for 10min ruining the engines cylinder walls and shit, idling is not good for a car. Nevermind the waste of gas.
Things like starters are cheap and are covered under warranty.
Adam Evans
If it's got a separate remote fob you could put the fob on a carabiner so you can leave the key inside with it running and quickly disconnect the remote when getting out.
Jackson Jackson
BULL FUCKING SHIT ! Idling your car 10 minutes IS better than restarting the car , the fuel consumption is nothing
Jaxson Martin
How about you just do it the old fashioned communist way and look at your oil and see if its dirty or not? There are so many automated and set in stone rules and gauges, but in my opinion my family, theyre really not that useful unless you dont really know what youre doing automotive wise
Hope you enjoy this info Veeky Forums, because when someone else makes this same thread 3 days from now, im not gonna answer it. Im not answering any of your dumbass beginner questions over and over lol
Jeremiah Cox
My oil looks like #6 after 500 miles. Do I change my oil every 500 miles?
Jaxon Gonzalez
I was told in another thread that engine starts when the car is at operating temp put very little wear on the engine--it's the cold starts that do it. You guys disagree?
Isaac Ramirez
Yes. That's right. When you warm start the engine the parts are still coated with a layer of oil as well.
Christopher Hall
thats where you fuck up, by measuring oil changes by miles instead of the quality or clarity of the oil being used. A vehicle may need an oil change maybe once a year, maybe even longer. Another vehicle may need an oil change once a month. It all depends on how quickly your oil becomes dirty, NOT by how many miles youve run the oil.
Zachary Howard
The thing is oil goes black from heat. My oil will go black after 1 tank of gas if I beat on it.
Do you think the oil in this video should be changed because it's full of contaminants from being in a flask for 5 minutes?
Parker Cruz
....or you can not change your oil and have a fucked engine. You seem to be leaning towards that. I mean, burnt oil is effective right? Fuckin Veeky Forumstards
Bentley Baker
Yeah. I'll change my synthetic oil every tank of gas then.
Jesus fuck.
Dominic Miller

Your shitty honda's engine oil is looking that burnt after a tank of gas, and youre trying this hard to keep yourself from changing your oil?
Yall are so fuckin dumb, im outta here. no more Veeky Forums for me
Brayden Myers
My k24 accord made it 6-8k miles before the "oil life" hit 10%. It may well be your stop/starts; cold starts and short driving intervals that dont raise your engine to operating temp will shorten the lifespan of your oil. Do you get the fancy new nanny tracking advert toppers for your pizza delivery?
Zachary Martinez
Because it's a waste of money? The engine has 40k miles on it, the previous owner changed oil every 3k and I have the documentation.
Redlining the engine a few times a day for 2 days will turn the oil black.
I guess I'll get oil analysis done at some point.
The coolant temperature (I have an addon HUD) is almost always at the same temperature when I get in the car so it should be at temp.
I don't have any topper or even a uniform.

>Conventional oil lasts 5000km >Semi synthetic lasts 7000-8000 km >Synthetic lasts 10-15k km That depends on: 1. engine 2. profile of use 3. ambient temperature 4. age of engine
Aiden Martinez
Anyone who goes by the colour of their oil as an indicator of its condition should be forced to drive a twizy for the rest of their lives.
Diesels especially will darken the oil after about 300 miles, petrol in about 1000 miles. I would be much more concerned if my oil was still golden when it was changed since it would be holding fuck all in suspension.
Joseph Murphy
It's just a timer it goes off after 5k, 10k or whatever is the recommendation to change
Jeremiah Long
>Does anyone actually follow their oil life monitor? They do seem to have logic behind them beyond the claims by some people they are just timers. Mine supposedly uses many factors including temperature, how hard the engine was run, the load on the engine. and the type of driving such as stop/start, city, and highway mileages.
I did notice the percentage dropped a lot more than usual after I attended an Veeky Forums meet with lots of hooning. The percentage drop off also matched the visual oil changes too. Normally, the oil would not have changed that much in color. But it was quite noticeably darker after the meet. Therefore, I have some confidence that the oil life monitor in my car works as it coincided with the visual changes in the oil.
Zachary Nelson
My car has an oil life monitor yet no fuel monitor.
What did they mean by this?
Adam Gutierrez
Honda uses FRAM filters
Charles Stewart
I burn 1 quart every 1000 miles, so I'm replacing the entire volume of oil once in between my changes. I could probably go forever and just screw on a new filter every now ant then
Jaxon Jenkins
Did you reset the computer clock? I changed my oil last month and I got the 15% oil life light on this saturday despite my oil being physically fine because I didn't reset the oil clock
Ethan Johnson
You still want to change the oil because as it drains out, any sludgey sediment that has settled to the bottom of the oil pan will come out.
Nicholas Nguyen
At least the car is still warm, so it could be worse.
Ian Gonzalez
it probably goes by a 3000 mile change
there is nothing there monitoring the quality of your oil
Camden Rogers
More like 7k intervals. OP is just an idiot and is constantly shutting off and starting his car dozens of times a day without getting it to proper operating temperatures
What can you expect from a Pizza delivery boy?
Christopher Ross
oil dipstick is broken. the metal piece is stuck in the tube.
I don't want to remove the tube out completely, I have to unloose parts to get to it. If I cut 2 inches off of the top, would it do any harm ?

Ian Watson
>It's still worse to have the car idling for 10min ruining the engines cylinder walls and shit, idling is not good for a car.
That's primarily a diesel problem and it's called wet stacking.
You see it more with pump controlled injectors or any scenario where the injectors are firing too rich.
>Redlining the engine a few times a day for 2 days will turn the oil black.

I'm driving up mountains all day in 104'F heat, the car is parked no longer than 15 minutes at a time. It's definitely at operating temperature.
Isaac Rivera
>I'm driving up mountains all day in 104'F heat
Then your oil minder is probably right, and you should change your oil soon.
Just switch to the cheapest dino juice you can find and change it once a month if that's your normal driving routine.
Oliver Ramirez
>constantly shutting off and starting his car dozens of times a day Doing that a lot means the oil is also diluted not just by the fuel, but also by the combustion byproduct vapors that get absorbed. While fuel and water is evaporated by the hot oil, some of those combustion byproducts take a lot longer to drive off.
OP here, changed my oil with $19 motomaster synthetic
Camden Hill
Also i was completely wrong, the last oil change was 8k km ago so the oil minder is right.
Cameron Rivera
>he wants his car to think for him

Luis Nelson
>OP here, changed my oil with $19 motomaster synthetic Your local walmart may also have competitively-priced full synthetic oils in 5-quart jugs. The famous name-brand oils all have good additive packages. Mobil1, Pennzoil Platinum, Valvoline, and Quaker State full synthetic are approx $24 for 5 quarts at my walmart as of last week.
Justin Clark
Motomaster stuff is made by shell and basically pennzoil platinum
Joshua James
But without the pennzoil additive package.
Jackson Hall
No, the comp in my e46 m3 starts at "25000km" left, which is extremely optimistic. I usually change oil and filter every 8k.
Liam Russell
My full synthetic oil gets dark too fast for your color chart to be usable. It's a new car so engine wear can't be the issue. And I've used the different full synthetic oils of mobil1, valvoline, quaker state, and pennzoil. All of them seem to get to your #6 at 1000 miles when I look at the oil on the dipstick. You need to qualify your color chart I think. Such as how thick is is the oil sample in a rectangular examination tube and not a round test tube. And the intensity and distance of the light source needs to be specified as incandescent and LED lights yield different results when reflecting or being shined through from the other side.
As it is, your chart has me changing oil probably between the range of 800 to 1000 miles for a new engine using full synthetic oil and running on top tier arco detergent gasoline.
Robert Wilson
Mine seems to go off like clockwork at 10k miles, But No i don't follow it. I keep track of my mileage
Daniel Watson
I just put in some new semi-synth oil every 10,000km.
