Synthetics reveal leaks, not cause them

[@MacRobbSimpson]

Yes, exactly. It makes leaks worse; I'm not sure if it's just due to being synthetic, or simply a thinner base stock(the 5W vs 15W part). I will say in my experience, with 7.3 IDIs... If you've got a typical older engine with weeping seals - a few drops here and there, not enough to worry about - on 15W40... do NOT use 5W40 synthetic! It's going to start leaking massively. On the other hand, if you've resealed the motor... go ahead! It'll be fine.

[@gilbertodiaz-castro626]

After working for over 40 years on all types of vehicles and support equipment (generators and air compressors) I've learned that synthetic oil use has caused leaks to start on equipment but it is not because the oil damages any component or seals; the reason these leaks start is that synthetic oils have a higher detergent content and they clean up all the dried up gunk between the seals and the shafts. these deposits are built up over years of use and they get caked on to the seals, once the synthetic oil cleans this mess up the hardened seals are not able to keep the oil in the assemblies. So the answer is NO, synthetic oil does not cause leaks, worn seals/shafts do.

High quality synthetic oil has anti-sludge additives that can sometimes open old paths that were closed by dried sludge causing a leak. But this means that the seal was probably bad and due for replacement.

I was taught the synthetic has a smaller molecular structure and that is what would cause the leak. If I also add in what Vlado T said and think about gaskets and seals being made stronger now. That really makes sense why leaks would've happened in the past and dot now

My experience as a mechanic: Typically, in a well maintained, or newer, or low miles/hours, or engine that started using synthetic oil early in its life, won't leak at all. Older engines, or ones with high mileage and have never used synthetic almost always leak when switching to it. Synthetic oil itself doesn't cause leaks, it simply exposes already bad seals that the conventional oil couldn't sleep through. Once you change the seals, the leaks stop. Great video as always! I especially liked the T4 and T6 comparison, thank you

Syntetic oil is not the primary cause of leaks. It just wash away slug from the seals and if seal are already old and lost its elasticity or damaged - it will leak.

when I switched to synthetic oil on my 1963 KMZ (Dnepr) K750M, it did start to leak oil around the alternator, but not because the oil eat or destroyed the seal, but because it worked so well with its anti sludge properties, that the old gunked up oil around the old seal (just one big o-ring) was removes, but after replacing that seal, my engine works like a charm :P (the old seal was dry and had no elasticity left)

With that being said, my personal 86 F250 6.9 Diesel always used a qt of oil every 500-750 miles. Oil changes done religiously at 3K. When I switched to the exact synthetic you used in this video, the truck would use 1 qt of oil every 250-300 miles. Never leaked any. After 3K miles , and 10 qts of oil added , I switched back to conventional oil and it went back to the same 1 qt every 500-750 miles. I did not notice any MPG improvement or changes in power when using the synthetic . Truck had 200K at that time. Keep up with the great videos !!

I am far from a professional, however work in the automotive industry. I like the video. The general consistence on synthetic oils is they do not cause leaks.

This added to the fact that synthetic oils are designed to flow better results in existing small leaks to become more obvious.

That is not entirely true. Seal polymers change volume depending on the chemicals that are exposed to. Synthetic oil tend to swell seals less than mineral oil. For this reason some suppliers add "seal swellers" to the oil so the problem is completely gone. This is an issue that was relevant 30 years ago. Modern seals tend to behave better with synthetic oils.

[@Slazlo-Brovnik]

@@fragglefknrock7568 Sorry - but ... no. The question is not if a car of this and that age is considered "antique" or not, this is just a word. The question is why exactly synthetic oil might be a problem. And that is the case because of some seal-materials used in older cars. These seals can be damaged by synthetic oil. I could go a bit more in the details here but unfortunately I do not know the english technical terms for the materials etc. in question (I am German). Basically the design features in question have been in use prior WWII and maybe a bit after that. More or less those seals (and some other design aspects such as the absence of an oil-filter) are not in use anymore since the early 60s. Of course stuff changed from 80s -90s to today, but for the question at hand that does not matter - the important change was done way before that. So again: Regarding the question "How old must an engine be, so that synthetic oil may be harmful to it" the answer is: It must be build prior ca. 1965. Okay, there is ONE possible issue with that statement, and that is: I am talking about European engines. It may be that in the US those older designs where used longer. But I doubt that. And even if: Not into the 80s. And BTW: Project Farms test just kinda supports my statement, don't you think?

[@johnnyohness]

Just discovered your channel. It is first-class in every way. About 18 months ago I bought a project truck 94 F250 with7.3 IDI engine. I bought it because it ran so strong. First I changed all the fluids not knowing what kind of oil was used in it before. From the time I owned it until I got the time to start working on it, I noticed it didn't have a leak of anything. First I changed the oil and went to a synthetic. Since then I have spent $$$ on body and paint. Though not many miles were put on the truck I noticed a small leak in time out of the rear seal. I put a quality stop leak additive in it but it has not stopped the leak. After seeing this video and reading the comments I now understand how the new oil may have created the leak. I've also noticed a small seeping of the valve cover gaskets that wasn't there before. I will have the repairs done because I can't stand any leaks in any of my cars. Now, I'm wondering to avoid any new leaks after the repairs should I go back to conventional oil? I don't want to create any new leaks that are not there now? Your opinion would be greatly appreciated. PS there is no wonder why your channel is doing so well. Your stats are off the hook. Your hard work has really paid off. Good for you.

Another great! I have to agree with some of the comments in regards to leaks. I feel it doesn't hurt any seals. It will clean better, arguably, and cause some more weeping around old seals and gaskets. I believe the molecular structure is smaller as well. Like air vs helium in a balloon, the helium leaks quicker thru the permeable rubber vs the straight air, right. I have also been told that after a while the leaks will slow because the synthetic oil will condition the seals and gaskets. However I have never witnessed this to be accurate because if I have a leak it drives me nut and I have to repair it. Wow that tractor is sweet! What a work horse!

With any research, this is a myth; the reverse is actually true, as older synthetic oils were made on different processes, that resulted in a more corrosive oil. But newer production processes have been refined to produce far less corrosive synthetic oils. If anything, a few rounds of modern synthetic oil in an old engine can reveal previously existing leaks that a few larger particles out of the refined oil had previously clogged.

Just wanted to share my experience switching to synthetic oils. I own two motorcycles each of which are nearly 40 years old. I'm sure they've both been using conventional oil their whole lives. When I got them I switched to synthetic. In fact, I use Shell Rotella T6 because it meets the JASO-MA specification. I've never had issues with either bikes consuming oil, or leaking. I also use synthetic oil on both of my cars. No issues there either. And I'm willing to bet both of my cars spent most of their lives on conventional oil before I purchased them as well. Heck, I even use synthetic oil in my lawn mower, and it's never given me issues either. Synthetic oil does not cause issues. Skipping oil changes causes issues. I will always use synthetic oil in all my motors.

I have not had any issues with synthetic oil either heck i didn't change the oil for 5 years ran up 100,000 miles.

Always go synthetic it makes a huge difference. I even use synthetic in my commercial lawn mowers and snowblowers, it’s amazing how much longer the oil stays a light amber color. When I would use conventional sae 30 it would turn black in 1 day or less. Also much easier cold starts when the temps are low in spring and fall on the larger engines on the zero turns. Used to kill batteries cranking in the morning start at least once a week on something, now never.

[@upnorthviking823]

It lasts longer thats it.if you change your oil often there is no need for it.you can change the oil on 12k km intervals with syntetic.

[@Lincolnator721]

While synthetic oil won't create a leak, it will find one. That being said, additives can help with leaks. A temporary solution for minor leaks.

[@r.j.bedore9884]

Synthetic oil causing leaks is a myth. Conventional oil tends to have far fewer detergents and dispersants than synthetic oil, and it also tends to contain more impurities. This means that conventional oil will be both more susceptible to sludge buildup and less capable of removing said sludge and keeping it suspended in the oil to be removed by the filter. Conventional oil is also more volatile than synthetic oil of the same viscosity, which means that as the conventional oil is heated the "lighter" components of the oil are boiled away leaving behind a thicker oil. This happens to some degree with synthetic oil as well, but as you could see from the oil pour test it has a much greater impact on the conventional oil's viscosity. This thickening phenomenon is one of the reasons why they have you change your oil at regular intervals, and why your vehicle's owner's manual says to change it more often if you put your vehicle through more heavy duty use cases, like towing or racing, since your engine will run hotter for longer in those uses. Synthetic oil's resistance to this thermal breakdown is one of the reasons you can go longer between oil changes when using synthetic oil. Putting all of this together, an engine running conventional oil will have more sludge buildup and the oil will get thicker the longer it is in the engine. These two things work together to mask any marginal oil seals that are on their way out and would otherwise be leaking. Once you make the switch to synthetic oil the extra detergents help clean the sludge out and the "thinner" synthetic oil will begin to seep out through the areas that were previously plugged with sludge, exposing the bad seals. If the engine had been somewhat neglected before the switch to synthetic and hadn't been getting oil changes on time, or if it was operated in particularly wet environments (water in the oil is one of the sources of sludge), then the amount of leaking after the switch can be significant. If, however, the vehicle was well maintained with on time oil changes at the appropriate intervals for your use case, then the engine likely won't exhibit any leaks when switching from conventional oil to synthetic oil.

[@EgorKaskader]

So the engine would be in poor condition either way, you simply would learn about it sooner and in less disastrous a fashion then, is that correct?

[@r.j.bedore9884]

@@EgorKaskader More or less, yes. If you switch from conventional to synthetic oil (keeping the same viscosity) and start noticing leaks that weren't there before the switch, then you likely have oil seals that were going bad, but too much sludge had built up in the worn areas to allow much oil to leak out before the extra detergents in the synthetic oil cleaned out the sludge. If this is the case, then the oil seals are likely to need replacement, though sometimes it's the shaft the seal rides on that is worn or scratched and that actually needs to be replaced. Either problem though could have been masked by sludge buildup.

[@MacRobbSimpson]

@@r.j.bedore9884 In my experience, it's not so much sludge buildup as probably the thinner viscosity you 'get' with typical synthetic - going from 15w40 conventional to 5w40 synthetic, for instance. I did try it on a slightly weeping engine(very typical, and something that would work for years this way) and, well, those leaks became *massive*. After losing two quarts in a couple hundred miles, I threw in some Lucas to thicken it up, changed the oil back to conventional at like 3K miles, and the oil leaks dropped back to a 'nominal' level... and I'm pretty sure that engine is still in working shape to this day. (on a freshly-rebuilt engine with new seals, I ran synthetic with no noticable leaks at all)

[@lordsesshoumaru8596]

kinda wrote a huge oxymoron, " synthetic oil causing leaks is a myth...if, however, the vehicle was well maintained..." which is it ? switching to a synthetic oil in an engine that doesn't leak because of sludge build up really doesn't matter, the detergents can clean up a little but are more meant to maintain a clean engine by stopping sludge before it starts, not even the solvents in an engine flush would clean out sludge build up. Perhaps more than synthetic oil but not enough to unclog a leaky seal, under the sludge is varnish that would need walnut blasting to remove.

[@johnstewart7059]

I always like your testing, very impressive and thoughtful. I started using synthetic oils in the late '70s, Mobil 1. That was because of military experience with them in jets. The "leaks" are generally from older motors, that have used conventional oils and there is "sludge" build up. This generally collects in recessed areas of seals. Due to the improved detergent action of syn-oils, and ability to flow freely, the gunk that was actually acting like a plug gets cleaned out and that is the leak source. Mobil had a great series of informative articles that compared natural and syn oils after very high mileage and hard service uses (taxis) and compared cleaning actions. You may be able to find those. Didn't expect tractor to leak, however get an old Ford with 300k on it and try the same test with a normal 3000 mile test, you may see something there Keep up the tests, really enjoyable, like AvE and Big Clive

@@KingAdrock420 I am thinking back a long time ago, cork gaskets and Permatex, and Pennzoil. Lots of build up. Mobil did tests and synthetic oil had superior cleaning and they did not reccomend on high time motors. They even advertised you could run that oil for a year, just replace the filter at recommended intervals and top up the oil. I did that on my Toyota , a 1977 Corolla and drove the snot out of it. I had an oil temp gauge too and it ran cooler, lower friction?

[@johnjohnson6379]

In my experience with synthetic oils,I have found that if an engine has any seeping or slightly leaking gaskets,the use of synthetic will worsen a seepage to a leak and will worsen a slight leak to a real leak.I found this to be true on a 1995 Grand cherokee with a 4.0 6 cyl .101,000 miles and a seeping valve cover gasket(not dripping) and an oil pan that would leave a drip or 2 in the driveway only about once a week.After doing an oil change with synthetic,only a day or 2 later there were multiple heavier drips on the driveway.Much worse than before.So bad after a week that I did another oil change changing back to conventional.So where synthetic oils dont make a nonleaking engine leak oil, it appears to make any seeping or leaking much worse .

[@mwv8408]

OMG! I've not watched this video yet and I will, but I'm going to comment about this FIRST! YES!! OMG YES............................... and worse! And it can cause engine rattles, BUT! that's in engines that have lots of MILES on conventional oils, I had TWO disasters in two different cars in the same time frame, one was a Nissan pickup and one was a Chrysler Lebaron , both with over 100,000 miles on them. Here is what happened. I was into researching motor oil for a popular motorcycle forum and I got caught up in the marking hype of the Synthetic oil and the EXTENDED oil changes, with the regular oil filter interval changes, change the oil once in between oil changes, and top of the oil. Two of my own vehicles. So, I bought the famed Mobil-1 and changed the oil in both vehicles thinking I had did something GREAT! and them came the mid filter oil change and that went well, so the wife and I drive ON! well then came the actual oil changes in both and that went well but the oil looked a LOT darker then I expected, so we drive on. Well, in a couple of thousand miles on the Chrysler and the wife comes and informs me her car SOUNDS AWFUL and is rattling like crazy!!! so I go out and check the oil level, its fine! I start it up and it sounded like it was coming apart, not knocking but but like a couple hands full of boxed end wrenches was left inside each valve cover!!! My thought was the SYNTHETIC OIL did something, and it did. I drained out the oil removed the the oil filter, went to the parts store, bought 5 quarts of conventional motor oil and a new oil filter put it in the car and started it up, IT SOUNDED LIKE IT WAS READY FOR THE JUNK YARD!!!!! I let it set and idle for maybe 20 minutes, and the oil pressure gauge showed NORMAL oil pressure. I decided to take it for a gentle drive and about 30 minutes into the drive it still sounded bad, but it wasn't as bad. Over the next several weeks of normal use it got a little quieter and quieter, in a couple of months the noisy reduced to so slight ticks, to finely near normal. But, during this time the Nissan pickup was only a couple of weeks behind the switch to Synthetic oil, and the EXACT same thing happened to it!, and I did the exact same thing to cure it, I thought I had ruined both engines. Now, to the WHY and to the why the change to synthetic oil on high mileage engines can cause oil leaks. In the early days of motor oils it was believed that the crude oil was from dinosaur remains, will now know now that that's NOT true at oil, but for the purpose here I'll refer to it as Dino oil. The conventional oils is WAY better these days than in the days of old, BUT! they can still leave what I call "Dino Plating" in an engine, not SLUDGE, but a golden varnish color. This plating grows and presses in against seal lips at the shafts and it also plates the internal edges of the gaskets. As the shafts at the seals and the seals wear the plating grows and fills in the space, it also crowds and fills in in between all the moving metal parts inside the engine, more wear, more room for dino plating growth, the dino plating on the gasket edges plates them enough so that they dry out and start to rot. Now, lets say this has been happening for say 180,000 miles and we get the idea to change to a Synthetic oil, this oil doesn't have anything in to produce this dino plating and without that its actually starts to break what plating is in the engine down and cleaning it out. Well, this wonderful running engine and all its parts has formed the PERFECT union with the dino plating sense it conception, now that the rotten gaskets are getting exposed to this new oil and in a far less condition to control oil leakage by themselves!, and the lips of the oil seals that had been crowded with the dino plating and made room for loses their sealing position and starts to leak and the formally crowded metal parts have this NEW found space and they start to rattle. My older brother was a Firestone store manager for 25 years and they STOPPED doing synthetic oil conversions on higher mileage engines do to all the FALL OUT (problems) from doing it, leaks and rattles!!! The dino plating comes from the remaining tars and paraffin's that smoke and burn off and then collect inside the engine, these can't be gotten completely out of the oil via normal refining! However seeing how synthetic oil is molecular-ly dismantled and the crude (I call) oily's are collected, then re-joint into new molecular chains that didn't exist in nature before (making it synthetic) means that 100% of the tars and paraffin's are taken out (actually left out). Will it do this in your engine? how many miles is on it? how much dino plating has the years of conventional oil left in it? its a roll of the dice. So, make your own choice, but for me if its an older engine with considerable miles on it that's running good for its age, I'll let the sleeping dog lie, its already got a happy internal union inside, if its happy I'm happy! Thanks for all your video's

On the flip side of this though, I had a 1969 Ford F100 with about 130k on it. I put synthetic in it and about a week later noticed small drips on my driveway. It was the intake manifold gasket, but I'm guessing the cleaners in synthetic just unplugged an existing flaw in the gasket that was covered by gunk.

@@AZGladiator and honestly I think this is the key here. People notice leaks that would have already been there but the synthetic is cleaning so well with the better additive packages they usually have that it cleans the gunk that was plugging up the leak that was already there. Honestly it’s kind of nice to see what is about to break and what needs to be fixed. If u are trying to get another 6 months out of an old beater with a leaking head than I guess it’s not as nice.

I was a little surprised to see you add that oil additive for compression help, being a self- proclaimed skeptic of products like that, but it made me feel better cuz I do it too. Thanks Todd

I buddy of mine used to spray the bottoms of his 60's - 70's Mopars with fuel oil once a year. He would Park it on cardboard for a few days to let it drip dry and get the stink off. His cars went 10 or more Michigan winters and the bodies looked like new when he sold them.

So the T6 has lower levels of Zinc and Phosphorous. Yet still showed a smaller wear scar on the timkin machine, which replicates flat cam and lifter wear. Just how important is ZDDP?

I have used fluid Film in past, it did it's job, needs yearly reapplication,

I’ve been watching your channel for some time now, and I love all the new equipment. New freezer, new burners for heating the oils, and awesome drone footage.
