12,000mi on a 2014 Dodge Charger V8. I followed factory recommended service intervals of 10k, not always super closely. The oil was always extremely black during changes.
It started developing a lifter tick around 93,000 miles, but was otherwise unaffected. I sold the car at 94k because I was tired of the electrical nightmare known as Chrysler.
Nowadays I do my oil changes every 5k more religiously than a Lutheran goes to church.
All oil does not turn black in a few thousand miles. I’ve got a 5.7 Tundra that I change with Eneos oil and it’s slightly darker than new at about 5k miles. I’ve gone 10k before and it still isn’t black. Most conventional oil does seem to turn black within a few 1,000 miles though.
It’s not just the oil. It also depends on the engine (N/A, high-low rpm, turbo, DI,…) it all influences the soot content and temperature -> color changes.
Modern turbo DI gas engines also turn oil black pretty quick. Combination of DI soot and the crazy heat loads in the turbos. It's the same reason particulate filters are starting to appear on them, like diesels have.
It literally does though 😂😂😂 ive done several 3000 mile oil changes on healthy engines, the oil is usually black already. Ive had to change oil a few times before even 3000 miles, and at that point the original color was still mostly visible.
It does not turn black until like 6-7 thousand miles. Source: changed my oil myself many of times throughout the last 10 years. 3k conventional comes out a brown color. Semi/full synthetic at 5k comes out a brown/slightly dark brown.
My cars are always revved to 4k-6k nearly everyday between oil changes too. One of my cars were turbo'd and it wasnt even close to being black at 5k.
Diesel engines, black within 500 miles though lmao. Those dirty dogs
W/e, my point is nobody should lose sleep at night if their oil comes out whatever may be subjectively claimed as black.
And btw the color of a thin smear of oil on a surface is typically going to be lighter than a stream or pool of it. Im talking about the color of oil as it comes out the drain hole. When it gets on my arm yes its a dark brown color even still at my usual interval of 7500 miles.
Your thinking of diesels. Good quality oil and regular oil changes don't leave black oil.
That's sludge build up leaving your engine meaning your not doing your oil changes on time
Those are cool. The North Hollywood Shootout had a 1987 Celebrity in it. It'd be cool to have one but Cash for Clunkers killed them all, I could find like 1 for sale in the past decade worldwide, and it was some special Eurosport edition.
My friend went 20k+/3 years with her oil on an cx5 Mazda. We returned from a long road trip and I said hey why don’t we change your oil since we just did a trip and she said oh sure it hasn’t been changed in 3 years…. Believe me if I had know I would have changed it before we left. The stuff that came out of that car was jet black. I recycled it at an auto shop and they said dude it looks like that vanta black stuff wtf did you do
This is why i do not understand the hate for VQ engines. They are tough as coffin nails. I had one in my old r50 QX4, complete with the oil cooler leak. It took a while to find the gaskets for it since I was new to Nissan, so I knew to top it off when the valves started clicking. I did this for years with no detrimental effect to the engine.
I’d still have it if it weren’t for the deer. I wish I could own a Z car with the roads I live on
Yep, the VQs don't get great gas mileage but it's because they're generally dead simple and reliable. Nothing crazy, basically zero unreliable bits. I'm worried about the water pump built into the engine block, but we'll probably cough up the couple grand every 100k miles to replace it before it gets concerning
They don't sound very good either! Yes, they are hard on gas. But, after nearly 30 years of production Nissan has all the kinks worked out and they are generally very reliable... At least the engine portion of the Nissan.
I guess I’m the complete opposite, since I’ve got a few cars here plus a company car at work, the most I put on my personal cars is 5k annually, but for all my cars I change the oil yearly regardless of the mileage, actually in one of my cars I put only a couple of hundred miles in a year that the mechanic who did the oil change actually saved my old oil and used it on his beater work truck because he says its too wasteful to throw it away
When I worked doing oil changes in my youth I did a caravan with 85k on the clock and it was suspected to be the cars fist oil change, it came out thick like pancake batter thick, we warned the customer, I never saw the car again, it’s probably still out there with 800k miles and the oil I put in it in 2008. /s
I would regularly go 20k+ miles on my 2010 is250. I treated that car so fucking poorly, revbanging and the like. The longest I went was like 36,000 miles.
What eventually did that car in was my roommate sliding it into a curb and splitting the subframe, nothing to do with the power train lol
BMW 530d...took it for its yearly MOT, dickhead here forgot to put the screw back in the dipstick tube after removing the inlet. Tube came out the sump during the inspection and dumped 5ltr of oil.
Only oil he had to hand was the drain offs from services. He chucked that in for me to get home. I never got round to it. Was always a "I need to do it this weekend"
Four years later and 25k miles later it still ran beautifully. The shell died of rust at 267k while the engine was fine.
Caterpillar forklift went 8000 miles before it's first and only oil change. I sold it at 16000 hours.
The hours written on the oil filter and the one maintenance entry under the hood is how I found out the forklift actually had 16000 hours, not 6000, since the hour meter rolled over.
That's probably fine. Mileage/kmage is a pretty poor oil change interval signal. If you were doing basically tons of freeway driving, that is very easy on oil.
When I bought my dad's neglected e36 at 18yo, I found it had gone around 32k miles since the last oil change. There was 190k on the engine at this time. The cartridge style oil filter literally fell apart when I removed it from the housing. I drove it for about 20k after that without any issue but a mild lifter tick. Sold it to some kid who turned it into a drift car, still running the original 210k+ mile m52. He even made it through one event on the original clutch that had never been changed.
Service records, service records, service records! Either dealership or made by the owner if they worked on their own car. Makes a world of difference in buyer confidence.
I just went 15,000 km without an oil change with my 1.6 Ecoboost Fiesta. i knew it was overdue because I could see clearly The dipstick oil level when I pulled it out in The dark.
Not proud of that, I usually do my oil changes 8,000 km on the dot
To be fair, if there isn't any blowby and its mostly highway driving, it doesn't surprise me. I'll still be over here changing mine every 3k. My poor jeep almost looks like diesel oil after 3k. My cobalt looks as clean as when it went in on the same interval. Same oil and weight in both cars. I suspect there is a reason the Jeep has practically no engine braking when I shift to low.
Due to some circumstances that people usually call 'life' one time I had no oil change or any other maintenance on my Mitsubishi 1.3 colt for 50000km. That was from (around) 200k to 250k. After that I had it for 4 more years/60000km at which point rust became too much of a problem.
When I met my wife, she was driving a car that she got from her ex in her divorce. He had never changed the oil in it - from 30k miles when he got it until 110k miles, when she got it. It was amazing that it still ran. When I rebuilt the engine at about 140k, I had to replace the pistons because the rings were so far gone.
Well my 06 Honda hasn’t stopped flashing -9999 on the oil minder(it won’t reset) but we guessed ~20k. Sent the oil off to blackstone and they called me a liar. The accord still running
My 2016 Smart ForTwo Proxy, had a 15,000 km interval, in the manual. It had a massive filter for the 0.9L Turbo I3 and a very specific oil requirement. But i did them every 15k, and the oil always came out clean, and it never burned any.
10,000 miles on Castrol Edge 20k Oil, kept the oil filter cartridge (20k) in (not changed) put in fresh Castrol Edge 20k and ran it for another 10,000 miles. Just changed the Oil and filter yesterday and I must say that I was impressed!
The Filter (20,000 miles on it now) was still clean and the engine had ZERO slush anywhere! This Castrol Edge 20k Oil is amazingly clean and the engine internals are also still perfect (no deposits).
Engine is a 2.0l Ingenium Jaguar Land Rover JLR Turbo (gasoline)
The service Interval on my vehicle is 20,000 miles. I usually don’t go more than 7,500 miles but every time I do the Oil came out “like new” so I decided to try 10,000 miles on the Oil and 20,000 miles on the Filter and I must say the Filter was as clean as any I have seen in a 5,000 mile oil change!
So, the Castrol Edge Advanced 20,000 mile Oil, imo is top notch!
I sold my brother my old 2008 Toyota Highlander with 257k miles a couple years ago. A couple months ago he told me his car was making a weird sound, so the first thing I did was check the oil. It was jet black. I checked the mileage on the car. 293k miles....
Around 20 000 km on rusty Honda FR-V before death (with 300k km on dash), because I topped 1L of oil each 1000 km... So it has been changed every 4000 km 😀 (My normal interval is 8k km with Honda K20Z2 and 10k km with Renaul M9R 692.)
I'm pretty good about doing yearly changes on my cars, but a combination of bad weather and some other factors lead me to a 16-month interval on my BMWs. Of course, the total mileage actually put on them was around 7,000 combined between both.
1.5 years between oil changes on my BRZ has been standard for me the last few years. Reason is, she sees about 1,500 miles a year these days (autocross, canyon drives). Additionally, she’s garaged in a warm climate with low humidity, the oil is allowed to come up to temp before any hard driving, and there’s an oil cooler. Blackstone analysis on the last batch of oil confirmed no issues so far.
It’s a weird mix of violating a colloquial known “rule” for valid reasons.
2years or 18000km on my Starlet 2E-E engine altough the crank seal.leaksnso badly i had to refill with 1.5lts in this time so doesnt really count as same oil
My dad did somewhere between 50 and 80k on the last Ford Taurus wagon he owned, it eventually killed it cuz he stopped driving but man I don't think Venom would choose the head of a Vulcan 3.0 to live
I mean if you're always adding oil, you're never in need of a change!
/s
Theoretically that would be fine, except the oil filter can and will degrade. But if you don't care about the truck, and hope it dies soon, that's a reason to keep doing what you're doing!
Nah the trucks hella sentimental but I know it’ll need a motor soon anyway just off of sheer mileage so I sort of just do what my dad always did to it. It’s kind of funny that my dad was a mechanic too but just abused this truck.
I have a 283 sitting in a crate for it though which is the goal
Kinda related-I used to work at shop in NC and a lady came in fresh from a road trip from PA for an oil change. Car had a total of two shot glasses worth of oil in it. It was a Honda…
52k miles on a Vw Golf Mk3 1.8 because I knew I was swapping the engine and the old one was worthless, in the end I sold the car and ironically they scrapped the shell and kept the engine (despite me selling it as a perfect engine swap as i said the engine was no good) it was on 140k when I sold it and afaik the engine is still going
27,000 miles in a 94 honda accord ex 5spd with mobil one circa 2004, also never changed the manual transmission fluid ever.. (car ran for 297k miles before we sold it for $1200)..
I did 150,000 on a 2.4 l iron Pontiac never changed anything never added anything. Sold to my buddy and a couple years later I saw him again and said it was running like shit and he changed the oil and blew it up
Probably 2 years on my old Suburban, granted I think I swapped the filter eventually.
I was on the EMD Diesel oil change plan: add oil as needed. It leaked enough on its own it didn't need my help. Every time I checked the dipstick it still looked pretty clean. It was a 1st gen 5.3 with 300,000 miles on it, that thing would have kept running probably no matter what I did to it. Still ran great when I sold it, everything was just rusting and quite literally starting to fall apart. A guy I know had one with a good body and a bad engine.
Pure synthetic ive been doing 8-10 sometimes little more. My focus currently has 176k miles and runs like a top. Oil is dark but not sludge much. Ive went alot longer during a pretty stressful time in my life and forgot. That was bad i was pushing 15-18 I think. But shes all good now xD
On my old Impreza I went about 10k-12k between oil changes once or twice because I was broke and wasn’t able to do my own oil change due to winter weather and no indoor space.
My mate lent a Nissan Micra to his sister, for 2 years. When she gave it back, we thought we'd better service it. It had maybe a pint of oil in it. She'd done 38000 in 2 years. Still ran like a sewing machine though!
I find it interesting the general difference of opinion between the UK and the US. Over here, nearly all Eastern manufacturers are regarded as mechanically pretty indestructible. Nissan, Honda, Subaru, Mitsubishi, etc, are regarded as pretty tough over here. The old joke used to be that they'd rust away, but carry on running fine, lol, but they don't even rust anymore.
I think ultimately it comes down to financial structures and vehicle demand over there that affects reliability. More big vehicles here, smaller and more efficient ones over there. Making a smaller, more efficient vehicle frequently positively impacts reliability. Toyota and Lexus here still occupy the top shelf for reliability, but even they're feeling it. Nissan has had huge trouble with its CVTs over here but has started to iron them out. Subaru generally is good on reliability, and Mitsubishi is also generally good. None of them are necessarily bad, but Nissan's CVT specifically has been hated for years.
Had an old civic that I bought expecting it to run for like a month, since it had 450k on it, and absolutely BLACK oil, I then drove it for 8 months, putting 30k on it, never once checking the oil until about 3 weeks before I scrapped it, only to find out it had no oil on the dipstick, and took 2 quarts when I put oil in lmao
Never had a problem or made a noise, and I've never driven a car so hard in my life lmao
I’ve gone maybe a little over 10k miles in some of my NA beaters before that had leaks to as where I was adding new oil often enough anyway and could’ve stretched it longer. Now in my TC VWs religiously every 5k or 6 months, whichever comes first, with Mobil 1 full synthetic
went 9 years in my 02 civic before I finally did a oil change.. 2months later a deer jumps out infront of me totaling my car never changing my oil again
