Why is This the Best Engine Oil for Your Older Mercedes Benz

[@ralphthornhill6663]

I appreciate Kent for sharing his years of knowledge for diy'ers.

[@cino4919]

I've been using the LiquiMoly 10w40 Super Leichtlauf ( blue canister ) for a long time in my old Benz's. Engine runs noticably more silent. After 6000mi / 1000km oil change intervals the oil still looks quite clean. I would definitely recommend this brand. Here in Europe it costs about the same as any other premium brand oil.

[@anassnouri6129]

The fully synthetic one right

[@cino4919]

​@@anassnouri6129 I don't know if it is fully synthetic, but it meets Mercedes specifications 229.1. Works for me, use them in my W126 M103 engine.

[@anassnouri6129]

Yea that’s the light blue one it’s fully synthetic, I swear when I put it with one botttle and a half of ceratec engine sounds like brand new and it accelerates better and so effortlessly, I swear it’s not a placebo effect, been working on these cars for Years

[@roveradventures]

M103 someone was running Castrol 5w30 in the motor. Swapped to the oil shown in the video. Oil pressure light stopped coming on, maintaining 1-1.2 bar at hot idle temps Lifters are much quieter and the engine runs smoother. Will consider using liqui moly in my M113 AMG engine. They make tons of neat products from what I've researched! One even glows in UV light to detect hard to find oil leaks :)

[@r.weaver3769]

I am right there with you, Kent, I use Liqui-Moly Molygen in mine. Oil analysis shows engine wear has reduced since using it over the M***L 1 oil, but I also started going by the testing labs recommended oil change interval for my engine based on my analysis, which is less than Mercedes. Instead of 10k we are doing 6k. I hope to get another 10 years outa the old girl.

[@gerardjurgens2670]

I like these videos of the old mercedes and I just happened to need engine oil for my 2005 Kia Besta 2.7 diesel. I live in Chile but I am also from Holland like the mecanic in of this channel so I understand his sense of humor! I just ordered a 4 liter can of this oil and I am happy to know it slows down wear! It was one of the more affordable choices when it comes t engine oil so I saved money too like Zeeuws Meisjelll Geen cent te veel hoor!!! ☺️☺️🇳🇱🇨🇱🇺🇸

[@damianu6514]

Learned a lot from you Kent. You should do more videos on valve ticking, its a pretty common issue on the v8's.

[@bernardschlaphoff4266]

The MoS2 anti-wear works great, reduced noise and general smoother drive with the MoS2 oil. Also getting a reduction in fuel usage.

[@silkroad3210]

. How about liqui moly Mos2 oil additives? Can we use it on 2014 Vito 122 cdi v6 engine as well?

[@estefanofanhani]

in brazil there is an additive roccol asos is practically pure molybdenum disulfide. It is simply the best thing there is.

[@zoltantakacs866]

Somewhen I shall try it. (unfortunately here in Hungary it has approx. 2x higher price than other usual reputable oils of the 10W-40 category) But we love our old cars...

[@daveh2612]

Thanks for the great video, Kent! I have been using LiquiMoly in M113 engines as well since they are also very sensitive to poor oil maintenance and develop valvetrain noise as a result. It makes a huge difference! I love that R107 with the red over tan and euro headlights. Beautiful car!

[@JohnsJohnson-ns5xm]

What weight for your m113?

[@SuperMAZ007]

I agree with Kent 100%. Chain ware is to do bad engine oil(lack of oil or poor maintenance of the engine). Liqui Moly I have used in other vehicles(none MB) and despite it maybe a pit spicy on price(depending where you live in the world). It is worth the money and saves your new rebuild or old engine from a lot of problems.

[@Airman..]

Liqui moly and fuchs oils are top tiers and I have been using them for years and I convinced many people to follow along

[@bretnickerson8555]

Hi kent, your channel has been incredibaly helpfull for my w123 and w126 .

[@budweiser93]

Back in the late 1970s Atlantic Richfield (Arco) sold an oil called Arco Graphite. Came out of the bottle black like that.

[@loboestepario-cl]

In WW2 the germans used MoS2 and water to lubricate tanks engines in Africa, due to allies actions to cut oil suply. MoS2 adheres firmly to metal with mechanical pressure.

[@waltpartymiller6802]

Knew that you used it, but didn't know why. Good explanation. We used to buy tubes of Molybdenum Disulfide to squeeze into the transaxles of VW Type 2 transporters & buses. It would quiet them down.

[@studplayrico]

I started to use Liqui Moly 10w40 on my 1997 Lexus LX450 and the engine ( in line 6) runs very smooth. The engine has over 196,000 miles.

[@thaddeauscaldwell7101]

Thank you Kent for this great video. I had been researching for what type of oil to run in my three Mercedes, Porsche, etc . It's good that the oil quietens the engine and seals leaks , etc. too

[@Mercedessource]

Glad to help

[@19jacobob93]

I will support your claims! I haven't used this oil but I have used Liqui Moly's MoS2 additive for years. It goes into my 1992 W140 with an M104 and my E36 with an M43. I have even started adding it to my girlfriend's 2019 Hyundai with a GDI engine, as these have a Molybdenum Disulphide coating on the piston skirts that is prone to wearing off and causing accelerated wear. I feel by adding it to the oil their is a constant supply. I always notice a more refined running engine (smoother and quieter) to anything I add it to, and also reduced oil and fuel consumption in older, high mileage vehicles.

[@ejsgarage]

I have been using Liqui Moly for my Porsche and VW

[@henrimaciel2404]

You are very strong men all my respect

[@avivscrewvalla]

I used 15W-40 MOS2 engine oil following Kent's recommendation and noticed quieter and smoother operation in my OM617 motor following completion of my Auto-RX engine oil treatment. I expect better fuel economy and will report back if so. I can't claim that it has reduced any oil burning or leaks just yet but will keep an eye on it.

[@MrRjnr]

Any update? I just acquired a 1980 300SD with 156,000 miles; wondering which oil to begin using

[@Keeferlgb]

Following....I just acquired a 1979 300SD as well. Is this oil good for both gas and diesel engines with more than 150,000 miles?

[@juanitamckenzie4226]

I should add that I've had my Benz for 2 yrs and according to AAA insurance guy the meter has read that mileage since 2012.

[@aomar9449]

Tons of great advice for someone new to older Merc's, thanks for sharing

[@pete538]

own a 99c44 with the m113. has over 200k. bought it around 118k. oil burn has gotten a little worse over the miles (1qt every 500-1000 miles depending on driving habits). I've always ran 5or 10w30 mobile synthetic. when I got it @118kmiles the oil burn was about 1q evey 1k miles. love this engine and car

[@Sonolaleggendadeimotori]

Hy, dall'ITALIA, canale molto bello. Lo sto guardando nei dettagli e filmati. Magnifico vedere queste Mercedes e poi i tuoi racconti molto belli da seguire. Bravo Mi sono iscritto al canale

[@javantgarde]

My 1997 C280 with the M104 Inline 6 with 190k miles was burning a quart every 2000, I switched to a high mileage version of Mobile 1 full synthetic 5w-30 and it stopped burning completely. Might give LM a try if it helps with timing chain wear since I haven't had any problems there yet. 👍🏼

[@ulrichskaarsgard7848]

Yes Liqui Moly is the best.

[@mattszurko2831]

Kent, firstly I love ALL your videos!!! I will start using this oil in my W123 going forward. Do you recommend this oil for modern Mercedes? I have a 2013 W212 that I want to last as long as my W123. I've been using the recommended Mobile oil (changing at 4-5k mile intervals, NEVER the 10K recommend in the book) but, have never been a fan of mobil oil.

[@MrTheHillfolk]

They got their butts handed to themselves back in the 80s when they started using it in aircraft. Something about the lead in the fuel getting in the oil from normal blowby and coating the insides with this shiny goo all over. Replacing an aircraft engine isnt cheap, about 7-8yrs ago dad had a little 65hp rebuilt and it was like 14k,and that's a peashooter 4 cylinder,sit down for 6 and 8 cylinder pricing.

[@DannyColdhill]

Agrees! Use it in my racecar with absolute no issues.👍👍

[@CheezyDee]

I wonder how well this would work for older American engines with flat tappet cams, can't run regular oil in them either due to the lack of zinc additives.

[@jimmycarter9099]

Thank you for your videos I appreciate you I have a 300e just a toy I love the car and learn a lot about it my Mercades mechanic. Become good friend s he put a Transmisson in for like 1300 dollars I enjoy driving the car , thanks for your service tips happy new year to you and family.

[@freddyhollingsworth5945]

We have a 2,500 unit U-Pull here. 7 out of 10 vehicles that come in, not crashed, simply come in only because they were ran dry on engine oil, usually 15,000-25,000 miles since the last oil change per the sticker on the windshield. No one cares about engine oil or checks it anymore.

[@oby-1607]

Why would you say not to use this oil till over 100,000 miles? Wouldn't it be better to use this right away to prevent the wear evident at 100,000 miles and get longer life out of the chains and the cams?

[@yolsclassics6347]

I run Mobil 1 European Formula 0w40 for my 1999 CLK430 w 150k and just started putting LubeGard Oil Treatment in it. I have seen this Liquimoly around and have been tempted to try it. I run very aggressive oil changes on her ( every 3500 - 4000 miles ). Does not burn oil. But I love tryinf new products. Let me know what you think Kent! LOVE your videos!

[@mustir7667]

Would this oil be recommend for a om601 with 100k miles?

[@V13teampain]

Would you recommend this on a w201 2.0 E 4 straight cylinder. It has no leaks and not burning but it has 428k km on it :).

[@squid667]

This was a very nice and informative video. Would this oil also be good for our car? We have a 1979 W123 with a 230 M115 engine. It has driven 192.000 miles but it has very little blowby. And the timing chain has 2 degrees of stretch. Until now she has mostly run 10-40 mineral oil. I have only owned a W123 for 3 months and are a bit green when it comes to these cars. We had a number of them in the family when I grew up in the 90s but that is a frighteningly long time ago.

[@luuuuuudoooooo]

Hi Kent, great info! Do you have similar tips for gearbox oil/ axle oil by any chance?

[@wingman427]

Interesting to see significant . the wear on the cam shaft. My understanding is that oil additives have changed or dramatically reduced because of catalytic converters. Does the V8 engine you showed have a flat tappet or a roller cam?

[@kino9371]

I used 7 liters of Liqui Moly 10w40 MoS2 for my automatic 250D last month. Should I need use MoS2 anti friction too? I couldn't find SAE version of this oil in my country.

[@NLatkovic]

Help - have 82 240D daily driver in Palm Springs - 105F in summer. 230K+. I always ran 10w-50 Rotella or DelVac. Took it to the local dealer for the mileage badge and decided to have the oil changed. They changed it to Mercedes Diesel Synthetic 5W-40. My regular guy changed back to 20W-50 regular oil. Do I go Mercedes Syn Diesel or Rotella regular 10w-50? Liquid Moly Diesel?

[@juanitamckenzie4226]

Should I switch to this oil for my 1990 300 SEL M. Benz ? Not exactly sure about mileage due to broken speedometer cable, which reads over 170,000. My car does make a rather loud tappen sound. I love my Benz, it needs much more TCL that I can give it right now but I do do my best.

[@Mercedessource]

You definitely then have high mileage. Yes I would switch. Report back if it helps with the noise. If it is a lifter the noise may go away.

[@MrSuperAndrey]

Is this oil good for old Mercedes engines that have low miles? I have a w124 200E from 1991 (M102 engine) with around 80.000 miles and I ordered this oil.. But I'm not sure if it's going to harm the engine :(

Please sir which oil for my w203 mercedes year 2004

[@jfysjoel]

Hi Kent I am living in a tropical country in Asia. I have a M102 200E which seems to be burning oil. I am currently on Mobil 1 5w50 full synth oil. Does full synth/ semi synth/ mineral oil affect the rate of oil burn for these older Mercedes? I notice that the liquimoly oil you are recommended here is a fully synthetic oil. What are your thoughts on this?

[@Mercedessource]

This oil is not a full synthetic. It is a blend. Oil burn depends on a lot of factors. Have you done a compression test? Could be piston ring wear. Your M102 engine may need new valve guide seals ( a common problem due to age). Oil type may or may not help. I am not a fan of Mobil 1 for 1995 and older engines.

[@jfysjoel]

@@Mercedessource Thanks for your reply Kent! I am planning to do a compression test, have suspected that it could be piston ring wear. the latter item might be an expensive job so I am considering "cheaper" fixes first. let me check out the valve guide seals! I have had the car for almost a year now. for the first 6 months of ownership using mobil 1, there was no oil consumption. only after the first 6 months did I notice that I have to top up 0.5 quarts of engine oil every 1000km (600 miles). Hence, I was thinking that the detergents in this full synth oil might be "cleaning out the cylinders too much" is there a particular reason for why you are not a fan of mobil1?

I would not recommend 10/30 in an old Mercedes V8 with over 100K. At cold startup 10/30 and 10/40 are going to behave pretty much the same. It is running the engine hot for long periods where you need the extra viscosity to protect your 560 engine.
