How Oil Pressure Works - EricTheCarGuy

[@robeaumont82]

It's taken me months to find a proper understandable explanation of how oil pressure works and this guy did just that! Top work.

[@risctakr]

I have worked on cars, trucks and motorcycles for years. Not as a mechanic, but because I owned it, or helping a friend. I am by no measure a mechanic. I just wanted to say I really appreciate your videos, because I have learned why things do or are the way they are, not just how you replace it. You have taught me how to replace it, what it does, why it does, and how it affects the whole system. Thank you very much for sharing your knowledge.

[@christophermcgovern5036]

It’s nice for someone to show real appreciation for what these people do on KZbin

[@della6143]

Thanks Christopher I listen to the video about ten times now going over it slowly ..really enjoyed the learnings and understanding more about how oil pressure is generated

[@doraspigelmire9063]

I have been a car guy for 40 plus years and you make the most sense of anyone I have listened to.

[@BetterOff735]

Thanks Eric for your experience and time you put in to make these videos. Its helping me to learn enough to do my own repairs. I'm an Artist/ Entertainer...and I am NOT a mechanic. But in just the past few months, I have learned to replace a water pump, remove my air intake and replace spark plugs ( I have a Mazda Tribute 3.0) Now, I am looking at replacing the Valve Cover Gaskets because I have an oil leak, and have seen some oil on the engine, on bottom of oil pan AND in the Spark plug wells. All these challenges have given me a new found "growing" confidence that "I CAN do it"... Thanks to people like you who teach and help with videos. Thanks Bud! Steve

[@ahmedhamoda2995]

i just respect you man, i've learnt a lot from you, i don't know how to say it right, just thank you thank you very much for everything, a very useful and very much helpful information

[@pgrens]

Excellent, Eric. One of the things I like best about your videos is that you do your best to cover the basic concepts instead of always diving straight into the minutia of details specific to certain cars or manufacturers. Next beer's on me!

[@TheCeki1982]

Eric is cool and explains things on a relaxed way.

[@snappytom1013]

Hey Eric. I have an anomaly that appears to be unique. I have a 2001 Jeep Grand Cherokee WJ Laredo. 4.0 liter 6 with 182k. I tested the oil pressure with a gauge tester. Cold it went to 50 psi falling to 9 psi as it warmed over therapy minutes. I have replaced the sending unit, oil pump with stock milling pump, and went to 20w 40 full synthetic. When warm it will still drop to about 10 psi at idle unless I run the AC to raise the idle. But if I shut it down for even two minutes when warm, the pump will loose prime and I need to give it a quick rev and it comes back up to 40-50 psi while driving. Engine is tight and otherwise runs great. No rod knock or lifter tic. And the previous owner had new pump installed in November.

[@WiPri0371]

@snappytom1013. My 4L I6 Jeep Wrangler developed something like that but not quite that bad. Engine oil just wasn't lasting for 3k miles. I had to change it much sooner. I couldn't figure it out at first. Until I paid attention to design. They had designed the thing with the exhaust wrapping around the oil pan on 3 sides, all within 2 inches of the pan itself. The oil never stood a chance. There was no heat shielding to combat it. (There was also no support at the collector connection of exhaust pipe, but that's a story of idiocy for another time). I toyed with the idea of an oil cooler, but ruled out out. I don't remember why (I haven't had/seen the thing for at least 10 years now. Got rid of it). What I did do was wrap the exhaust pipe near the pan. It helped, but was ultimately a bandaid. Wrapping doesn't last. It ended up finally costing me a lifter. I parked it and drove my truck until I could fix it. But my mom beat me to the punch. She paid no attention to her gauges and let the car overheat from water loss till the engine was severely damaged. I let her drive mine reluctantly but not without sternly saying she needed to get hers fixed fast cause mine was vulnerable. Two months later, I'm picking her up again from the side of the road where mine died. She no closer to getting hers fixed and there were no options left. She took a taxi to work. I pulled the valve cover off mine. Looked like freaking glitter everywhere. I wasn't mad. I passed that point in a hurry. I was done with it by then. Sold it.

[@Kman7607]

Just amazing explanation. I appreciate how you explain things but manage to not make me feel dumb in the process. This is a talent that not everyone has and it makes watching your videos very enjoyable. Keep up the great work!

[@Peter-od7op]

Hi great vdo is there a pressure relief valve on car engines. I work on plans and they have a ball under spring pressure to adjust oil pressure.

[@solutionrecruiter7130]

[@viper_guy]

Finally! Thanks for a fantastic explanation. I am having a motor rebuilt right now and I can actually understand what the mechanic has told me. Keep up this great channel.

[@dneitzke]

hey Eric, once again I give you a THANK YOU! , One of the great things I like about you is that your not afraid to say,that "your not sure about that" which in my book speaks volumes of your credibility, Way too many" know it all's" loaded on the net. been working on cars awhile now and completely lost track of the oil pressure scenario. And yes I am guilty of replacing a oil pump on a engine with wasted main bearings. Here is a trick, if you barley here a knock and you suspect a rod bearing, pull the vehicle perpendicular to a curb, drop it in gear with a warmed up engine and give her some throttle if a rod. or engine bearing is in suspect, it will definintely make it's presence audibly known. slightly risky,but if present,ya got big problems anyway. Stay the course, and be well !

[@ImaginosStudios]

A quick tip.. if you have a gauge instead of a light, like Eric said low readings will indicate wear, however high readings can be a sign you need to change the oil as it it tends to thicken over its life, thick oil will make higher pressure, but overall will be less flow. Which means some of the more distant parts wont get lubricated.

[@festushengombe6576]

Thanks Eric I just installed a new oil pump in my 95 ram 1500 and was disappointed to see the oil pressure was between 30 and 40, but your explanation says it all. You're the best 👍BTW I have over 212,500 miles on it.

[@Igivegoodhair]

Knowledgeable and presented well- good job! Thanks Eric!

[@rotimisoboyejo6747]

Eric. I like the way you break everything down to the basics. I've learnt a lot from this video. You've saved me a lot on this. Thanks

[@searchingthesound8488]

Got a '94 302 just lost all pressure today, dash gauge been actin funny for months, with good oil. My mechanic told me it was the main bearings. Used your video to learn a lil bit b4 diving into a new motor. Thanks. You totally backed him.

[@sethyukna]

This video is 14 years old. I just watched it, and it blew my mind. I had absolutely no idea why oil pressure was important, nor why it worked. I now understand....42 years later. Amazing.

[@noxious89123]

+1. When elevating a fluid, gravity is the resistance. Some cars have an oil pressure relief valve, sometimes controlled by a spring, which will open and release some of the pressure if it get's too high. If this valve fails, it will let the oil straight through without any resistance, and thus you lose oil pressure.

[@galsan76]

Excellent ways of explanation and very understanding using a very professional language and skills. Thank you so much for all of this hard work for the community in helping out with our mechanical needs and troubles. Greatly appreciate your kindness and love hearing you educating us. Sincerely Eddie

[@dabarboza51]

Eric is pretty much correct!!! You can have a massive pump pumping out hundreds of gallons per minute...or more!! But if there's almost no resistance, if there is nothing to put pressure against it, then there is little pressure!! A pump is used to create flow... Any restriction creates pressure. Yes, you need a pump to create volume and resistance to create pressure

[@paulwalker2267]

pretty much correct ? Da Barboza

[@paulc2787]

Thanks Eric...You're my hero of the month. This video makes perfect sense. It's not the oil pump. It's the oil in the system that creates pressure. Glad I didn't listen to my mechanic, he said I needed a new oil pump ($1400). I had him replace my 2005 Tahoe with high mileage oil and the pressure is back to normal 30 to 40 psi.

[@snapautomotive80]

Thank you Eric I have tried over and over again to replace the oil pump due to the low pressure gauge of the engine oil and now I have benefited from this information. Thank you

[@allianceofsteel]

Also in my experience I've found that type of oil can seriously change your oil pressure readings. I tried out royal purple synthetic oil and my oil pressure dropped to half what it is normally, the engine also made noise like it was low on oil, so I parked and swapped out for my usual Rotella T oil and wix filter, back up to 50psi around 60 before warm up, huddles around 45 all the time. Excellent explanation in the video. The engine in question is a 360 Dodge 1977 motorhome, so I have to be careful which oil I put in it. I've read that certain newer oils won't protect your older engines and eat the camshafts out of them in just thousands of miles.

[@HighestRank]

Synthetic oil requires a different filter material. See pureoil.com

[@lowkeygneiss7432]

Yes! That's what Eric the car guy said also

[@stack9866]

Eric, you really are an awesome teacher! Love your videos, man.

[@lloydammoguy3829]

Yeah, I thought that if you put a bigger oil pump on the motor I would have greater volume and thus, higher oil pressure. You are the first person who has made sense on oil pressure. Thanks.

[@Plasma216]

Thank-you Eric the car guy from Yukon, Canada, doing a 2006 volvo s60 2.5t , and you helped me learn, respect.., low oil pressure and trouble shooted.... it was the cam seal, oil pump seal and the oil intake was clogged, used sea foam... and changed such, volvos suck..., respect

[@kessiahyoung2365]

Eric, you are a natural teacher. I love your videos!

[@tacoswamper]

Dude, these videos are so interesting and informative. Thank you

[@nullall3607]

In physics terminology: P=F/A (I.e. Pressure is force divided by area) So technically the pump creates force that based on the various clearances (which shows up as the A= area in the formula) ends up bringing different pressure levels based on level of wear in the engine parts/ clearances. Of course a worn pump makes less force which does result in loss of pressure as well. So obviously you can have perfect clearances like in a brand new engine but a failing or worn oil pump and still have low pressure.

[@robbielangley8523]

This was a very informative video! My 2002 4.3 S10 (181,000 miles) has been having issues with low oil pressure (especially at idle) and was wondering if a new pump would have resolved it. Now I realize it might be due to engine wear (luckily the engine is not knocking or making noises). May have to go to higher viscosity oil to counteract the loss of pressure.

[@HighestRank]

Or it might really just be the pump.

[@paulfoo7397]

[@fastestmanon3legs454]

Yessir....It's called "restriction".... restriction gives you pressure... Your example with the water hose, you forgot to mention-the *volume will still remain the same* when you put your finger on the end. The amount of water coming out won't change-only the pressure will...great vid 👍🏼

[@tsimms561]

[@tedspens]

I feel enlightened! I'm among those who A) thought low pressure = bad pump, and B) thought the oil was simply pumped to the top of the engine and drizzled down through the inner parts. Thanks for clearing this up... it all makes sense now.

[@guitarguyjoefry]

You were the first guy I ever looked up on KZbin and you're sill the first go to guy every time. I wish you the best life can offer. Thanks for all the help. I just replaced the thermostat and on my test drive the oil pressure gauge was on the higher side. It was a quart low so I added too much but the gauge looked more normal just past the halfway mark. By the time I got home the gauge was all the way to the right High mark? I've had low pressure and had to add oil before but never had high pressure and had to add oil before. I've had this old 94 Ford pickup since it was one year old. It's been a great truck 265,000 miles still strong. Merry Christmas!

[@Cpt935]

There are some wrong information in this video. The example with the garden hose seems to be true but it is not. if you reduce the area of the hose, according to the Bernoulli principle, the speed of the liquid will increase. The pressure will stay at 1 atm since the water is let into the air. The same principle is used at pelton turbines. The lubricating film on the bearings is a hydrodynamic lubricating film. What is true though is that this will only work with parts which are not too much worn.

[@brentbradley6711]

No it creates more pressure in the hose

[@graham7513]

The fluid dynamic principle at play here is called the Venturi Effect, just fwiw...

[@bertsimpsan]

No it isnt

[@jimbuford4147]

Eric, I understand what you are saying but how does the oil pressure interact with the gauge to produce a reading? Thanks

[@jmbpinto73]

+Jim Buford When you have a gauge, it is connected to the outlet of the pump reading the pressure at that point. At idle, pump is working slowly, and pressure must be enough to move the oil around, at higher rpm, the volume of pumped oil should be more than enough to give maximum pressure reads. Most cars have only a red light, it is on when the pressure falls below a certain minimum value. (like when the engine is turned on or off). When that light flashes while driving, turn off immediately, and check the oil level. In case there is oil in the engine call road assistance and don't turn the engine on again.

+José Pinto Thanks Jose. It is clearer now.

[@smiley00341]

Great Job Sir!!!

[@JJ-wp5yn]

low pressure doesnt necessarily mean your engine is worn. pressure is inversely related to oil flow. The higher the pressure; the less flow you will get to your bearings, journals vice-versa. In modern higher reving engines, thinner oils are used to supply more oil to these parts faster.

[@stefankautzky5083]

its not low oil pressure in general, its loss of oil pressure.

[@THERIGGEDONE]

My thoughts exactly

[@darealblair3262]

Glad and relieved to hear the difference of what creates the pressure..

[@chavt66]

I have a 2000 Chevy Suburban with 270k miles and for the last couple of years I've been experiencing oil pressure problems. However, I believe my problems may be due to a sticking oil pressure relief switch/valve. Oil pressure averages about 40 lbs at idle and increases to 60+ when I accelerate. Occasionally, it will drop to 5-10 at idle and 40 when I accelerate. If I rev the engine for a few minutes, the oil pressure will go back to normal. Would using an engine cleaner/ help with the possible sticking switch? If so, is there a particular product you recommend?

[@jasontruman3220]

Try sea foam Flush the oil a couple times

[@fy25song]

hey eric. i have a 2005 crown victoria with 370,000 miles on it. what viscosity of engine should i use ? ford says i should use 5w-20 but i have quiet a bit of miles. should i use a higher viscosity or stick to 5w-20 ?

[@ericryderup1755]

+Saber Uddin Keep using 5w-20 or check if Ford updated their recommendation. He says in another video to use the same as manufacturer recommends.

[@philp8168]

Ford hasn't changed their recommendation when it comes to the viscosity of oil they use. they still use 5w20 motor oil. but being how your engine has so many miles as stated in his video he talks about as the clearance is get bigger you lose oil pressure. ideally if you were to use a thicker viscosity oil you should get your oil pressure better probably not 100%. but if you're not having problems with oil pressure I would just stick with the same viscosity.

[@thomasburns2557]

370,000 miles. On 5w-20. Sounds like your car is doing well. The most important thing your oil does is prevent wear. Everything else it does is secondary. 540rat has a blog where he tests different oils for their ability to prevent wear. Look it up.. Yes adding 20w-50 might make it " sound better" but the engine will then wear quicker.

[@thomasburns2557]

+bep2001 kumar The purpose of oil is to prevent wear. Going to thicker oil is only a deception. May "sound" better but may actually accelerate wear. The real pressure in your car that prevents wear is hydrodynamic pressure. This pressure is in the thousands of pounds per square inch. It is created by motion of the surfaces coated with oil not by your oil pump.

[@philp8168]

Thomas Burns oh your very correct. But ideally putting a thicker oil maybe would increase oil pressure but yes oil pressure is made by the outlet of the pump and your crankshaft journals etc.

[@EricDenny]

great insight here! I've never thought about it like that before. It's a great example of Bernoulli's Principal. But, I wouldn't say the pump has nothing to do with creating pressure. I would say the pump generates flow (volume) that is later regulated into higher pressures by restricting that flow. So, take the water hose and cut the valve off half way at the source and the pressure will slowly drop along with the volume. So a weak enough pump could certainly lower the pressure. I get your point though. The pump is most likely unrelated to low pressure problems. Metal wear is much more likely the issue. Good to know!

[@anthonyvitanza1711]

I used to build a lot of race motors and this man knows exactly what are you talkin about because we used to put the bearings on the crankshaft where did gauge underneath it talk it down and see what the gauge read I'm sure he knows what I'm talkin about I like him the only smog mechanic I've ever seen so far

[@NOBOX7]

actually liquids are very compressible, im speaking from an engineering perspective the term for liquid compressibility is Bulk Modulus

[@dwutschke]

True, however the reason that MIL-L-23699 (turbine oil) and more specifically MIL-PRF-5606H (Hydraulic fluid) are used in aviation is because they are not as compressible, on top of their standard characteristics, as other fluids (which is a big deal in a T701D Blackhawk engine turning 69,000 rpm cranking 1800 shaft HP at the 5606H filled gimbal). What Eric is trying to point out is that liquid oils are not nearly as compressible as a gas. We're talking about every day consumers looking for information, not trying to confuse them by tech'ing them to death... I understand people want to show their stripes, but keep it simple and don't ruin the main point.

[@NOBOX7]

Dustin Wutschke bullshit its the fact they stand up to 500 deg temps and it contains anti oxidant and varnish inhibitors , the specifications never mention Compresibility , the reality is non compressible hydrolic fluids are water based bro,,, crazy i know but water is dam near in compressible under even extreme conditions and its the last thing you want in jet engine oil at 500 degF , im not tryn to show any stripes im just speaking facts not bashing Erci he is the shit we all know this im trying to share knowledge brother, your not the first to give me shit and try and dumb down the world even more....

[@impiyakhenyamande4805]

Great explanations, very clear and easy to understand. It's not a thesis but it's reach is awesome

[@BobCaseyHome]

Oh, boy, Pressure!?!?!?! Any pump works by either creating a vacuum or creating pressure. That is how the pump moves the liquid. By constricting the fluid flow, you have the same pressure, but less fluid, so higher fluid flow. The pump is the main ingredient to create the "pressure". What is interesting is how when these parts wear, they allow oil to flow more freely. So it's not about pressure, but rather oil leaks in the components. Great view of the inside of the crank shaft. Thanks Eric!!!

[@BobCaseyHome]

What's great here is that Eric explains how low oil pressure "dummy" light may not mean a bad pump. Great info.

[@JodBronson]

100% CORRECT !!! If the Oil Pump created pressure... Once the Engine is on HIGH RPM... Pressure will build up, then the Hose and other Parts would " BLOW UP " in matter of Hours / Days. Btw... Don't forget Oil Viscosity... In the Summer we use THICKER OIL, in the Winter THINNER OIL, try it, you will see the differences. Older Engines.... Go with THICKER than what the MFR recommended :)))))

[@16thnative]

Very insightful, I never knew it worked like that. I thought it just pumped oil to the top of and around the engine. You really know your stuff!

The Cadillac Northstar (mine is a mint condition 1996 with 115,000) only has an idiot light. I have used synthetic oil since new, and at 110,000 the oil light would flicker followed by a "STOP ENGINE" message displayed on the screen along with a fast chime. I replaced the sending unit, still had the problem, then i went back to regular 10w30, and i have not seen the oil light flicker in 3000. I just drove straight down and back between Florida and New York, and all was great.

[@jamesnewton8164]

That makes sense thank you. I had a oil light flicker on my honda h22a engine so i changed the oil and put 10w30 in it and it went away. The oil was black and i found small crushable black peices in the oil pan. The car sat a long time and suddenly i started it and got that flicker at very low idle. I guess its time to rebuild, the engine must have been beat on previously cause it doesnt have many miles on it. Good vid thank you

Once again, Eric explains it great. Thanks for the info man. Old video, but still worth the watch!

Oil pumps pump oil and without pressure, the oil would not go anywhere. On the other hand, without oil there would be no pressure. Excellent video. Thank you.

I was going to buy an oil pump for my 300 i6. Now that I watched this guy I believe I would have wasted $50 bucks. Thanks Car Guy.
