Cars in Europe and the Rest of the World have had 10,000 mile oil changes for near 50 years, and yet cars in the US with 3,000 mile oil changes don't last any longer than they do in Europe.https://www.acea.auto/figure/average-age-of-eu-vehicle-fleet-by-country/https://www.bts.gov/content/average-age-automobiles-and-trucks-operation-united-statesWhy is that?
>>28960033because you guys use cucked engines that generate less than 200 hp and are less than 1.5L
>>28960033Everyone with half a brain does 10,000 km or 7k mile changes. The cars that snap chains at 100,000 km got 30,000km oil changes.There are new cars with 40,000km intervals because cars lasting longer than the warranty period are bad for their democracy or something.
>>28960033>yet cars in the US with 3,000 mile oil changes don't last any longer than they do in Europe.Because few ever do 3K oil changes. Hell, I'd be willing to bet that most never do any oil changes at all and only add when it's a problem. Or any other work for that matter. Boomers will trade their cars in when the warranty is up at 3 years and poors tend to only keep a car less than 2 years or they wreck it while drunk whichever comes first (the wreck).
>>28960033>Cars in Europe and the Rest of the World have had 10,000 mile oil changes for near 50 yearsWhy do you lie?
>>28960033It's them tipping the car after every journey.
I changed my shitbox engine's oil every 58k but I leave the oil filter on for 2 changes. I put on a fumoto valve and just slide the pan under and flip valve, so I don't use tools. Usually use pennzoil because I like cold flow.Have done this for 300k. It's over 400k now.
>>28960033euros never install mechanical oil pressure guages and see the viscoscity dropping off
>>28960096>euros never install mechanical oil pressure guages and see the viscoscity dropping offThat still doesn't explain how cars in the US don't last any longer than they do in Europe.
>>28960096I truck loses oil pressure at the 10k interval mark. Not totally obviously but it goes from above range to mid range on the gauge. Always wondered what that was about.I do 7k and 2 changes per filter now.
Few Americans actually do this. It's because we want engines to last and an oil change takes 10-15 minutes. Saving up for a new car takes hundreds of thousands of hours of work N/A - 5k milesTurbo - 3k milesFilter change every time.This is why I can bounce off redline doing donuts in cars with 300k miles.
>>28960148>hundreds of thousandsOr thousands.

>>28960156Because only American nerds on the internet are saying it. Everyone around me thinks 10-20k on a turbo is just fine.
>>28960033Why are Europoors so obsessed with what Americans do?
>>28960033I change my oil evey 6 months.And by "I" I mean I pay the extremely large dealership I bought my vehicle from to hire professional staff to change ALL needed oils, fluids, etc. when they perform my vehicle check-up for me as they upgrade any parts or solve any technical issues.It costs about $60.
>>28960033>cars in the US with 3,000 mile oil changes don't last any longer than they do in Europe.euro shit literally shits the bed at 60,000 miles lmoa
>>28960221>euro shit literally shits the bed at 60,000 milesAre you literally stupid? OP is saying cars of the same make and model in the US don't last any longer than they do in Europe, even when 3 times as many oil changes over its lifetime
>>28960220It's built into the car purchase/ lease and you know that.For me? I get a 5L of Castrol synthblend and a Bosch or K&N filter. It's about $45 in my Hiroshima sled.
>>28960046You still have to change the filter every 3k miles. Don’t be a Jew with your engine.
>>28960033americans cant afford new cars, so they think extra maintenance will counteract the abuse from niggers who lease and rent the cars they buy second hand
>>28960233I wouldn't go toa dealership but that was the conversation.I think change interval is more important than oil quality. I get mildly good stuff and change it often.
>>28960187euros get their cum supplies from usDon't want them to starve now do ya?
>>28960266I'll stay with my Castrol EDGElord, thanks. But, good for you.
>>28960033Completely depends on the engine, but of course you are too retarded to understand that
>>28960107its the same oil you fuckers are just running it longer because you dont give a shit about your turd peugot.
>>28960033I do it every 5.5k because that's where Blackstone Labs was the happiest with wear metals, and so far it's running like new at 232k despite being an engine people on this Estonian fly fishing forum would tell you should have lunched itself 3 times over by now.
>>28960315küll see laiali lendab.
>>28960033I do every other birthday and an occasional Christmas. Cheaper to just buy another engine instead of so much oil.
>>28960228
>>28960146>>28960055qrd on leaving the filter?New meta heard it else where as well
>>28960632I just buy a premium filter that's rated for 24k miles or whatever dumb shit and run it for 16k. When I first change the oil I mark the filter with a sharpie to know it's been used for one change already.I did this in a k24 accord, with the reasoning that many oem including Honda were now recommending oil filter change every other change on their NA shitboxes, with much shittier filters
America has a strong car culture, Europe does not. America has (comparatively) lax safety and emissions laws once the car leaves the lot, Europe very much does not. You can reregister and drive any car practically forever in America, in Europe cars that are too old get banned from cities and eventually banned from registration. So it's pretty obvious why the American stereotype changes his oil every 3 weeks, he has a vested interest in keeping his car running so he doesn't have to buy a new one if he doesn't have to or want to, meanwhile in Europe it doesn't matter since chances are it will be failed and scrapped for failing safety or whatever, and even if it doesn't it is guaranteed to be forcibly retired by the government 10 maybe 15 years after it rolls off the assembly line.
>>28960033>amerikkka>obsessed with oil changesNigha were allergic to oil changes, you ask some Stacy with worn out brake pads when the last oil change was done, and she cant tell you because we let any retard have a car.
>>28960107America has rust and the average person drives more in a month than the average Euro does in a year. So why would a vehicle that gets abused more and maintained less last longer?
>>28960033>Why are AmericansEven though oil blinds are heavily regulated in the US people still stress over brand. There's an entire fucking forum over here just for it. To answer your question most boomers still recommend 3-4000 miles because they lived during a time when fuel was dirty and oil blinds sucked. Hell some of them still think Pennzoil will grenade you engine because of some fuck up decades ago. Plus motor oil is cheap over here because we have our own oil fields.Most rational people recommend 6000 miles with cheap API certified synthetic blinds. Or just to follow the cars owners manual.
>>28961086This, I keep telling oil autists, the best oil is clean oil.
>>28961086>>28961166every time>i ONLY use AMSOIL PAO ESTER FULL 100% CERTIFIED SYNTHETIC 10w-30 NO friction MODIFIERS every 3000 miles and my car has been purring like a kitten for the past 30 years>oh i just get whatever's on sale at walmart or whatever and do it once a year. dad also did the same thing before i was even born before giving the keys to me.if you truly want a forever car worthy of becoming a family heirloom, you would prime the engine with oil on cold starts with an accusump.
>>28961234That's a lot of money when I can just park the car over a heating pad that is plugged into a timer and I can leave with 70C oil every morning.
I went 7.2k at the last change and that's when my shittastar lost a roller/lifter. Lesson learned. I'm being a cheapass and hoping a couple rounds of 2 and then 3k restore and protect at least gives me some more time before the teardown. No stumbling or logged misfires knock on wood.Change your oil dude.
>>28960212This is how you end up with a sump of group II 5w30 in your car asking for 0w20 on the oil cap, a tip of the fedora and off you go
I switched to 5-20 to get that extra little mpg back and it feels wrong.
>>28961254You should be using 0w20 for mpgs even if the oil cap says 5w20. There's no engine that won't prefer 0w20 over 5w20. Your cap just says 5w20 because common availability at the time. First number being lower is straight up better for all short trip and cold start scenarios, so every day. Probably makes +0.1mpg difference.If you want real results run your tires 10-15% higher psi than the door sticker. If you need 32psi run 36psi.
>>28961273>If you want real results run your tires 10-15% higher psi than the door sticker. If you need 32psi run 36psi.Yeah and wear out your tires and suspension quicker. Just look for some lower rolling resistance tires, "EV tires" being an example. If you're fucking with tire pressures and oil weights for MPG gains you need to revaluate your life.
>>28961242the accusump pre-pressurises the oil system, not warms it up. it ensures the bearing surfacrs are actually riding on a film of oil and not touching each other, which is why cold starts make up at least 75% of engine wear.
>>28961279Most modern vehicles the stock pressure has you driving on the sidewalls for comfort and noise reasons. If you only go a few psi higher it's likely you'll gain better tire wear.
>>28961281I've never seen an engine that did not have the oil pressure bypass fully open on cold starts. Forcing lubrication through the passages is fine and dandy but 0C oil is still dumping 2/3rds of its flow straight back into the sump. At 60-70C it flows like water, won't have flow restriction and will be on the valvetrain before the engine has fully self started.
>>28961286True, my Honda is at 32psi and shes happy to see me with the way those front tires are bulging, I even rubbed the sidewall lettering off flinging around corners.
>>28961380>I've never seen an engine that did not have the oil pressure bypass fully open on cold startswut. you don't want the bypass to be open while it's building pressure. The bypass should only open if there's too much pressure.The cold oil from the accusump is still protecting the engine in those critical few seconds that the pressure is building up during cranking, where the oil would otherwise have been drained from all the bearing surfaces without the accusump. That's where the majority of wear is occurring, in just those couple of seconds. The oil can flow faster if it's already warm but it's still not on the bearings prior to turning the engine over.I'm not quite sure why you think cold oil will go straight back to the sump and not the valvetrain but warm oil will; the passages leading from the crank to the valvetrain provide the path of least resistance compared to it trying to escape out the crank journals.
>>28961415Very few engines have cycloidal variable volume and speed pumps. Most when 30F cold oil would be trying to push 140PSI if the bypass didn't exist. Look at your own oil pressure sensor on a cold start. You should see it idle pegged to some fraction of the max psi rating of the engine until the oil has warmed up. What it means is significantly less flow to the unpressurized, gravity drained parts of the engine up top. An area which already gets the bare minimum.Anyways i think we stopped talking about accusumps and oil temperature flow effects so I'll leave it here.
>>28961455ahh right, I see what you're getting at. You need to plumb the accusump after the oil pump, not before. Else what you described probably happens.
>>28961273tfw 37/45 stock psi
>>28960033>and yet cars in the US with 3,000 mile oil changesNo one is doing 3,000 mile oil changesMost people don't even do 5,000Almost every brand new car will tell you 10,000 for synthetic.It's your choice if you want to treat your car like shit over one of the cheapest and easiest maintenance tasks that actually make a huge difference to the overall life of the car.Another garbage euroshit thread obsessed with the US and making lies.
>>28960033Average Euro drives 30-40% less than the average American. Regardless of maintenence, miles/km add up.Oil changes are cheap for most passenger vehicles. 5qt of good synthetic and a filter are $30 and 15-30 minutes of your time. Even people skipping filter changes baffles me just from the ease and cost. 5k with modern synthetic is a good baseline for maintaining lubricity, sheer and the additive package whether thats anti friction or detergents to prevent sludge. Take a sample of fresh oil, 5k miles and 10k miles and send them off for testing. At 10k miles you will see a sharp dropoff of additives and trace materials like copper, lead, aluminum and silicone. The average cost of paying someone to just replace a VVT actuator pays for a lot of oil changes.
>>28962320>Average Euro drives 30-40% less than the average American. Regardless of maintenence, miles/km add up.That means that the US should have even higher intervals than Europe.In the US more miles are driven on the highway, which produces less stress on the engine than driving in the city, which is more common in Europe.
>>28961455It's case dependant. Some engines are designed that way, some flow straight to the cylinder head galley from the cooler, which goes immediately to the valvetrain.The Pentastar is a pretty good example of a more modern and good oil flow design. Most of the time the oil cooler has barely drained out half its volume by next morning's startup and the head galley is mostly full.Accusump anon is right and you are right too. It's case dependant but a pressurizer always eliminates dry start. We could call the "more modern" design a "usually always a half wet start"
>>28962618Yeah except that isn't how oil works.Euros drive less, less often, and shorter distances. More short trips less hot running. Very bad for the oil.Oil with 15k km on it that is 2 years old is going to be worse than a fresh out the bottle non synthetic from 1996.The interesting metric to look at is vehicle age and engine problems. If the euros generally get the same amount of engine problems in the same 10 year vehicle life, would that not be proof that age of oil and use condition is what matters, not distance driven?
>>28960898American with a passport here. This post is retarded on so many levels I don't even know where to begin. Try actually visiting europe and I mean europe not "eurodisney and the louvre' for once. The most coveted cars in america are from europe. Every major automotive sporting event that matters takes place in europe, and is won by europeans. If you want to do anything in europe other than smoke pot in the red light district of amsterdam or travel between paris and london you need a car. Sure if you're a rich hippie student you can spend the whole damm summer taking a bus between santiago de compostela and your drug dealer's place in kreuzberg but normal functional adults drive because that's how you get around in real lifeHaving a strong car culture means appreciating nice cars and having standards, both of which are more of a thing in europe than in america. America is basically sub saharan africa when it comes to car culture. Anyone with a pulse can get a license, driving standards are abysmal, you can engage in mass slaughter and your insurance takes care of it and you can just keep that up for years and years with zero consequences because America is a failed state. All they sell in america is pickup trucks and SUVsAmerican car culture is "strong" the way cancer is strong, please just fuck off with your horrible takes
>>28962813Everything you said is a bunch of garbage and we can all tell.
>>28962901You raise some interesting points, but may I remind you that No U?
>>28960033It's a boomer thing from 50s-60s that stayed in national headcanon.New cars just tell you when to do an oil change.
I just do mine every year. Each car only drives 4-8k miles a year anyway.
>>28962926Mine comes on when it thinks its driven the oil life equivalent of 6000 miles. Usually by ~8000.By 6000 I can smell how poor the oil has become. Granted I have bad plugs and an exhaust leak problem, runs rich, and in winter the coolant never gets up to design temp.But the car's oil life calculator should know that, hmm? Why does it tell me to keep using oil going bad, hmm?
