How To Buy The Right Engine Oil

When buying engine oil for your car, there are a lot of things you need to know. What weight is right? What does 5w40 mean? Is your oil an approved oil? What are oil specs? Thanks to Liquimoly for coming by to talk oils.

Thanks to Steffen from Liquimoly for coming by and chatting engine oil :)

[@macdude3585]

HumbleMechanic what about if you have let's say a built engine for praformance aftermarket pistons,ect,turbo.

[@HumbleMechanic]

I think the right oils become even more important

[@A.Dude.]

Consider the fact that you lubricate all components like bearings, crank and cam ones (which basically are the most important). Your pistons are the least important in regards to engine lubrication. Stick with approved oil, trust me on this one!

[@patw52pb1]

+A Dude Most engine bearings are hydrostatically/hydrodynamically pressure lubricated and pistons are boundary layer/film strength splash/mist lubricated and oil for for both are equally important. Lubrication is only one function of motor oil in an engine, whether stock or all out high performance.

[@larryevans4959]

PAO is not "raw petrol" as he states at 6:33 To break it down in basic chemistry... Group 1-3 is long-chain simple hydrocarbons. Just a string of single-bonded carbon with hydrogen filling most of the the open bonds. The longer the carbon chain, the "heavier" the molecule, which is more viscous, less volatile, and more stable (for reference, Butane is a 4 carbon chain, Octane is an 8 carbon chain, whereas motor oil is around a 25-30 carbon chain). The more carbon-hydrogen bonds are filled in the molecule, the more "saturated" the molecule, which makes it more stable for a given weight. Group 1 is distilled from a solvent base, and has the lowest saturation Group 2 is distilled in the presence of hydrogen, filling most of the open hydrogen bonds, and creating more saturated molecules Group 3 is "hydro-cracked", where heavier hydrocarbons treated with hydrogen under heat and pressure are "cracked" to become "lighter"/shorter chain hydrocarbons with almost all the hydrogen bonds filled Group 4, or Poly Alpha Olefin (PAO), is also a long chain hydrocarbon. But, at one end of the molecule (in the "Alpha" position) is double-bonded carbon. This slippery synthetic molecule containing double bonded carbon is, by nature, more stable and less volatile than even a fully-saturated simple hydrocarbon. Group 5 is a catch-all for everything else (silanes, alkylated benzenes, esters, etc.).

[@svenschwingel8632]

Actually, molecules in a PAO base stock do not have C=C double bonds. C=C double bonds (or Pi electron systems) are highly reactive by nature so you would not want them in an engine oil. PAO molecules are synthesized as polymers from alpha-olefines which are defined by having a single C=C double bond on the first (so-called alpha position) carbon atom of the chain. During the polymerization, the C=C bonds are being broken and used to form long-chained base stock molecules, ideally with a high grade of isomerization as well (which is necessary for a high viscosity index). Also, HC or PAO does not state anything about the base stock's actual quality. Both processes can produce comparable results depending on the way the process is handled and which catalyst is used. There are poor HC base stocks which are inferior to even mid-quality PAO base stocks, but high quality HC base stocks can compete with even a good PAO in every aspect. The only thing that really sets PAO apart is that you can good quality and a base stock with high selectivity with a relatively easy effort, compared to HC. Sadly, you will never know how good or bad your engine oil's base stock actually is if you have an unused oil because no one will tell you about the base stock's viscosity index (VI). The only VI you will ever see is the one printed in the product data sheet - and this one is for the engine oil itself (which contains additional viscosity index improvers, especially if you run a higher viscosity range like 0W-40, 5W-50 or 10W-60).

[@tomasnokechtesledger1786]

The german guy is weak at oils and is pushing a Group III as the best base there is. It´s not better that group IV (PAO)...

[@kiannafuqua7926]

lol

[@amazoidal]

That "Catch-All" Group 5 is used in turbine engines. Huge PAO content.

[@tedtedness184]

NO, huge POE group 5 content. PAO in a turbine oil would varnish up and degrade. PAO cant take the heat like a POE.

[@CarsSimplified]

[@HumbleMechanic]

[@oliknow]

I like my Liqui Moly for years and years now, probably since when this video went online. Here in Germany it is widely available and considered the "good" oil to put in last after a flush. The oil, the additives (used with care and caution) and the overall perception makes me feel good using these products. Others might be just as good but I think LM is quite transparent about what they do AND they actually get back to you when you have a question as an end user. Quite good

[@viterete8]

Great video and explanation, Liqui Moly is the best. Greetings from Ecuador.

[@markday6524]

Thanks Charles another good and informative video.

[@mikeh6876]

I own a 1991 Ford Explorer which I purchased new. The recommended oil at the time was 20W-50 and I have used it ever since. Every engine rebuild manual says that synthetics will not work in my 4.0L engine. Despite that, I have tried both blends and pure synthetics - 5W30, 0W40, etc. Both turn black and drop my oil pressure. When I go back to the 20W-50 my oil pressure returns to normal and the oil becomes clean. One mechanic told me that the synthetic was blowing by the rings and that was what was causing the black. So, I guess the moral of the story is that many older engines, at least mine, will not tolerate synthetics. Love the channel - thanks for the great info.

Good video guys. I love it when the train spotting chemical engineers commenting, start to pull apart wayward remarks etc. The API grades and SAE oil viscosity recommendations by your vehicle manufacturer's is about all we need to be critical about when selecting oil but always from the perspective of the temperature range that we expect to operate the engine at. What I am curious to learn though, is whether there are any inherent disadvantages when using oils with very large viscosity ranges such as 0W-50 and 10W-60.

When you need engine oil, go the website of your preferred brand and use their Oil Checker to get a quote for the right oil you need. Most of the oil checkers ask for the car registration. Others go off make, model and year but its very easy to find the right oil. By the way, if its a 5w30 application, I always use VW504.00/507.00 spec oil because 504.00/507.00 is for both petrols and diesels and has a superior additive package.

I have a 2001 E320 wagon with 385k (city) miles on it and other than oil changes (0w40 Mobil 1 for me), I have not had to do any repairs to the engine itself. I have changed MAF's and crank position sensors once each, and because of the dual spark plugs per cylinder MB's plug interval is every 150k miles! Same goes for the 722.6 transmission, one of the best automatics. If the early 2000s Mercedes' didn't have the rust issue, they would be considered the last bulletproof benz.

very good to see a representative from one of the manufacturers coming out to share some of the secrets to motor oil.

Steffen said that current group 3 oils are outperforming group 4. with group 4 being pretty much the highest refined petroleum oil you can buy, I wander about this. I believe it is possible that the GTL group 3 may be close to group 4 but I'm curious as to how any group 3 base stocks will outperform a group 4.

[@FirstOnRaceDayCapri2904]

Modern Grp. III GTL base stocks are indeed really good.

[@hyperlogos]

The question is not whether they are really good. The question is whether they are better than PAO base stock

[@tiktianchan1913]

I think the point the Liqui Moly guy was making was that group 3 stocks see more development, and due to this are higher performing. With regard to this, I think this is an entirely possible. There are plenty of initially inferior designs that have gone further and faster due to lower initial costs or initial ease of production.

When it comes to thinner oils some people would say that the viscosities recommended are based of CAFE standards.

Also an engine may be designed to operate at its best with that specific viscosity too.

Liquid Moly has that 0W20 oil, clearly labeled for the new Volvo spec, and quite frankly is the easiest to find of the few oils that do meet it. I advise being careful as it is so easy to get the wrong oil; in fact, there are two Vovlo specs out there now, one for the new gen, and one for the previous 5/6 cylinder engines. Thanks Stefan.

I wish they made a group 5 like Redline and Motul.

[@tarquineous]

It is group 3, with [maybe] a splash of group 4 in it, like he said. Amsoil and Blue Diamond are group 4 and meet european specs, so I don't know why he said group 4 does not meet the specs.

At the end of the video I was still confused about oil. The thing I got from this is. Oil protects my engine and stick with the recommended oil the manufacturer specifies.

[@PalladianPD]

Just watched and read a ton about oil weight ant 4 minutes in it's already more info that I got from the last 2 hours.

I use 20 - 50 diesel engine lubrication oil in all my engines ( i own old machines )

Hi Charles Love your KZbin channel. You provide tons of great info to the general public. I have a question for you. I have a 2005 Subaru Forester that had the blown head gasket issue that Subaru’s are known to have. I had the dealership do the engine repair and a bunch of other stuff also. I was told by the dealership that one of reasons my heads blew is because I run Mobil 1 fully synthetic oil in the car. That if I wanted the engine to not blow the head gaskets again that I should only run organic oils in the car and not run synthetic oil. My thoughts on this is a much better synthetic oil will be in the long run a better oil for the engine. What are your thoughts about what the dealership stated and do you believe it to be true on why Subaru engines were known to be blowing head gaskets and burning/consuming more than normal amounts between oil services.

[@thedreadedgman]

Oil would not blow your head-gasket; a number of Subaru engine designs (particularly the 2.5l variants) are known to blow head-gaskets more then other makes... but Oil shouldn't be a problem, obviously you want to run an appropriate viscosity for your climate...

Great video. liqui moly had the perfect chance to give us a discount code but we didn't get one :/

[@VolksTrieb]

love liqui moly. Drive it in all cars ;) Nice vid, keep it up ;)

[@HumbleMechanic]

+Lord_Vader thank you!

[@abeibrahim5846]

Love the overview - I wonder if you can have a similar video for Liqui Moli additives. MORE IMPORTANT, can you please tell me, and like Oil Saver for the engine, does Liqui Moli has Coolant Saver for the radiator to rejuvenate and seal water pump gaskets?

[@garythompson2517]

Motul in the trans and Amsoil for the engine. Works great

[@RobertLeBlancPhoto]

Why is the first value called "Winter" when it's the viscosity measurement at 40C, which is over 100F? That ambient temp sounds like Summer to me. Winter is usually more like 0C or 32F.

[@kepguy89]

Thanks gents for an informative discussion.I'm curious on what the shelf life is on the Liqui-Moly is? You know, in case I run into a sale price and want to stock up. Is it the same for most other synthetic motor oil as well?Best Wishes to HM Charles on the new ERA.

[@aaronngongoma8137]

Just got my first MK3 2.8 VR6. With 245k km on it. Confused as hell as to what viscosity oil to run with. Thanks for the beautiful info on this video. But what I gathered is follow what the book says for the most part. But in in saying that I know 20W50 is what is recommended, but you guys don't seem keen on it at all. Any advice on what to run in my AAA motor? Just did a oil change today with 15w40. But wanna do another one quite soon if need be. Cheers

[@user-we23r23r]

Hi! Thank you for the video. I have a question. Which one is better between genuine manufacture oil(castrol professional oe for vw, audi, etc) and aftermarket approved engine oils(after market castrol fully synthetic oil, liquinoly, etc)??? I asked the part manager at the dealership, but they said too general answer like, 'professional oe is for dealerships, and after market oils are approved by vw'... what do you think about the quality of engine oil between dealer oil and after market?

[@bradlandon1128]

5W30 moble one 💯💯💯💯

[@johnskunk609]

Thanks for all the info in a manner that it could be understood. I'm still not sure if I should use Mobile 1 5w 30 extended performance 15000 miles for my 2014 VW TDI Jetta Sportswagen. I'm continuing the search by would like your feed back. Thanks for the videos.

[@HumbleMechanic]

As long as it meets that 507.00 spec I think you’re good mobile 1 makes great stuff. I think Amsoil is the go to for most hardcore diesel folks.
