Use 0w-20 oil.Bearings explode.
i love this new trend of blaming poor engineering on oil viscosity
>>289389220w-40 doesn't have this problem.
>>28938922Explain why the "metal shavings" all of a sudden became a thing right as we switched to water oil.
people rarely talk about oil contamination.using dirt funnels, or going to lube monkey places that have 55 gallon oil drums sitting for months with their cap offor better yet using pic related. the worst funnel made by man. they are impossible to clean. every single segment in that shit traps dirt.
>>28938968Oil filters are a thing. You would have to dump handfuls if dirt/sand into the engine to cause the sort of damage were seeing in modern engines. Even then it would only cause cam bearing failure. Most engines are dying from bottom end bearing failure. Oil is being contaminated by the shitty tuning of modern engines that dump raw gas into the oil. It still happens in Hondas even after their "software fixes".
>>28938968I just don't use a funnel and spill half a quart over the engine bay for rust prevention
>>28938922This, Honda uses 20 weight since 2003 and it's fine, then whack ass, bailed out, too big to fail Chevy switches to 20 weight and the fucking engine explodes because they can't make anything right so they blame the oil.
>>28938922But cars in the US specify a lighter weight oil compared to the same car in the EU and that's because companies are cheating CAFE tests to bring up their corporate efficiency score
>>28939008It's the cars anon, they're fucking junk my shitbox Honda from 20 years ago is running the same 0W-20 in cars now and I don't worry about it blowing up because the engine was made correctly
>>28938919>car recommends 0w20>just use 5w30It truly is that easy.
>>28938968You know you can just clean these right
>>28939314Agreed, PUP 5-30 on Amazon costs like $5/quart. I use it for all of my vehicles regardless of manufacturer's suggestion. 08 MDX, 2011 F150 6.2L, 2014 F150 5.0, 2012 LS3 Vette, 2013 R56 Mini, etc.But still, a shitty engine is a shitty engine. Good oil won't save it. L87 AFM will die. Kia will spin bearings. Hemi cams will be wiped like a Hillary email server.
I don't care how good your (reported) tolerances are, I'm not going to run piss-oil to assuage those efficiency claims.Film strength is film strength, engines have parasitic loss. Seized bottom ends are infinite resistance.Even the RC166 err'd on the side of caution with 10/30 60 years ago and they only used a single ring on the pistons to reduce frictional losses.
>>28939388You are way overestimating how high strung an average vehicle is, anon... you can beat the shit out of 0W-20 to like 270F before is begins to thin out (still not recommended to use it on track) but your average car or truck will never do that, yet people act like 0W-20 is this thing that turns into water because you slammed on the gas and the engine went to rev limiter while passing someone in daily use... it's fine, it's the oil 99% of people need because it cold starts beautifully without damaging the engine (that's where the wear is) and it's super slick at 220 degrees when you are fully warm.
>>28938968surely nothing a dousing of brakleen can't fix
>>28939346>>28939401they are very difficult to properly, and fully clean.if you cant shave a rag down the funnel, its not clean.
>>28939309lol yeah and i drive drunk every night and never gotten into a crash. other people crash but i'm drinking the same alcohol everyone else drinks so that's definitely not what's causing it
This the oil thread? What's the general consensus on 0w-16 or whatever the fuck Toyota is putting in their cars now. My lancer's engine exploded and I was eyeing them because CVT's can go to hell
10w30 minimum>but muh car calls for 5w-you drive an appliance fucktard.20-25 psi hot idle while not pegging the pressure releif valve is your goal.
>>28939398Kek niggas be driving cars on ceramic brake pads and all seasons, while acting like their gonna push 20 weight oil to the limit on the way to work.
>>28939398this, my civicbox takes 0-20 and i regularly sit in 4th gear near redline going 90mph on the highway.i send my oil for analysis once a year, its in tip top shape. they say there is some minor wear but its been like that for the past 5 years. its as expected.
>>28938919I use 5W40 as Renault intended
>I know more than mechanical engineers, oil nerds, and analytical laboratories>I cannot be wrong, my grandfather who's been on pension for the last 30 years told me thinner oil is bad!
>>28938919>doesnt ID engineits a toyota isnt it
>>28939507Lol reverse searched and it is a gay 3.4 tundra, which no oil can save because it's a gay turbocharged pickup truck that needs to be ridiculed
>>28939511Kek pottery
>>28939472I have a mechanical oil pressure guage and know more than you.
>>28939472>mechanical engineers designed the engine and oiling system for maximum reliability and longevity instead of meeting beancounter demands and government regulations.
You have no evidence at all that 0w-20 caused this. Tundra owners have tried all the oil viscosities within reason and there are blown engine examples for every viscosity they tried. It's a shit engine design that's the culprit.here's the reddit thread pertaining to OPs pichttps://www.reddit.com/r/Justrolledintotheshop/comments/16jgqck/my_2022_tundra/
>>28938968I always keep my funnels in plastic bags.
>Everyone calls Toyota's drivetrains outdated>they update them>they ACK extremely early
>>28939769It's almost like they actually suck at it
>>28939780Obviously, it's built in America.
>>28939472>trust da engineers goy!>why do you need a transmission dipstick? it's a lifetime fluid?!>why do you need a physical hand brake? it's cheaper for an electric switch?
>>28938919Plain bearings are fucking bullshit anyways, all engines should be using needle bearings by now, but companies will jew us for as long as possible.
>>28939780So is the L87. When was the last time a UZ or 2GR let anyone down at 30,000 miles?
What are the chances all of the smaller components are manufactured in china?
>>28938978Based real mechanic. No really, this is actually good practice. Worked on a mine and the most reliable and heaviest of duty trucks were just dripping oil over the blocks for this reason (not AN oil leak)
>>28939679OP is a faggot.I hate reddit recyclers
>>28938919>Use 0w-20 oil.should have used UwU-20 instead.
>>28939314>>28939382The issue is a lot of 5W-30 oils you'll find on the shelf are a lot thinner than 5w30 oils from 10 years ago. Mobile1 for example: their 5W30 is as thin as some 0w20's.I believe they're doing this to trick people into putting in a 0w-20 in their engine.>>28939472Engineers make products at the lowest possible cost.So yes, I do know better than them.Modern engineers are retarded.I know because I work with a bunch of them.
>>28939841Failed your studies, eh?
>>28939841>get 5W-20 synthetic >send it to Blackstoner labs>it's 0W-20It's really not a big deal, oil has come such a long way, that I trust 0W-20 in a 30 weight car over an old ass jug of 30 weight.
>>28939841SAE J300 is a standard that determines viscosity rating. ASTM D5293 and D4684 are the tests used to determine the W rating. Unless your oil analysis lab ran those tests (they didn't BTW), then you would have NO idea what the W rating is
>>28939382All synthetic oil for gas engines. Local auot parts shoos carry nothing else. Oil labeled as for diesel engines still dinosaur juice (and cheaper). Would use except diesel oil doesn't have the correct additives to deal with gasoline blow-by. Diesel engines place greater demands on crank bearings, so logically it should be better (all assuming the same viscosity numbers). Right?
>>28938968If it's trapped then what's the problem
>>28939809This guy gets it
>>28938919Use 25w-60 oil.Leaks get plugged up.
>>28939841Realistically, if you get it tested and it doesn't show any signs of accelerated wear, does the viscosity actually matter?
>>28939908>25W-60Jesus christ nigga, an F40PH train runs 20W-40
>>28939911yea twin towers anon well my SHITBOX runs ONLY the FINEST SHITBOX OIL
>>2893991125w50 keeps my fucked up motor alive
>>28939911S54 motors use 10w-60
>>28939908>>28939946Based Aussie nutters
>>28939844No, I'm the only assembly mechanic they can bunch designs off of to save their ass from making something that doesn't work.I've even made 3d models for them.>>28939853You can fudge viscous tests.See redline 5w20 that's as thick as their 5W30 >>28939910Nope, I've tested like 12 oils in various thickness.Wear results are basically all the same
>>28939990>fudge testsThey could but it's so regulated they would be out of business so fast. The big guys don't fuck around with that.When you talk about RedLine 20 grade beiing like a 30, they're talking about something called HTHSV. That's really the important spec. HTHSV varies a lot within grades, I think HTHSV is what you're always referring to
>>28939994Nah dawg, Raw new oil viscosity tests.Redline 5w20 is hella thick
>>28938919Chevy recommends 0W-40 Mobil 1 Supercar for Corvettes so that's what I put.
>>28940063Makes sense for a car that may see track use in its life, the faggot ass boomers cruising in their automatic corvette could still get away with 0W-20 and not hurt it, but it just goes to show the type of car and the usage dictates the grade of oil that should be used, but if you're not doing extreme use and you car isn't high strung, 0W-20 is what you should be using.
>>28940072>the faggot ass boomers cruising in their automatic corvette could still get away with 0W-20 and not hurt itYeah, no. I drive it hard and live in a hot state to begin with so the heavier oil is needed. I get wanting to baby it but it's designed to want to open up and the boomers that don't give them Italian tune-ups every so often and let them rip are lame. It's good advertising too.
