MBCA The Theology of Motor Oil

- Join us for a great Tech Talk video-teleconference (VTC) from Saturday, June 26, 2021. Certified Tribologist Lake Speed Jr. will discuss motor oils in detail to help you determine what motor oil you should be using in your older Mercedes engine. There are a lot of myths about motor oils and Lake will provide the facts and the science upon which it's based. He was forced to learn about oils when he was working for Joe Gibbs Racing, and after losing an oil sponsor they went to an off the shelf oil. Immediately, they started having cam failures when running newly rebuilt engines on the dyno. This prompted them to "design" their own oil, and it provides lessons that Mercedes owners need to know to properly maintain older Mercedes. Of note, Lake's daily driver is a 1983 Mercedes 240D, so he also has a special interest in diesel engine oils. Lake is currently the Vice President of Sales and Marketing for Total Seal Piston Rings.

We'd like to thank Lake for spending the time explaining the ins and outs of motor oil.
Thank you Lake for the outstanding presentation, and thanks to the MBCA Peachtree Section for making arrangements.
Thanks for the feedback. We view this as a real gem on the channel. Please share it to friends and family that you feel would benefit from the information.
Just about to switch out when I saw the old Mercedes on the 3rd minute. 😂😂. A long video. 20 years ago I had read tgat a well blend synthetic can be even better than a fully synthetic. If not mistaken base oil I is solvent extracted with aromatic still above 10%. Base oil II is lightly hydrocracked with aromatic below 2%. Base oil III is highly hydrocracked or even from gas to liquid plant with less than 0.1% aromatic and are >95% parraffinic. Its being said that additives need some aromatic to mix/blend well with the base oil. So is fully synthetic oil are using newer generation of additives which was not avialable 10 to 20 years ago?.
I am getting a old supercharged mercedes E200k which is famous for timing chain and sprocket wear which can happened as low as 60,000 miles. From your last hour of this video looks like it is better for me to use european spec of engine oil usable for both gasoline and diesel engine. Correct?.
Since I am in area a bit north of Singapore, which never drop below 70 deg F for night time to day time max of 98 deg F. I am going to choose semi synthetic 10W 40 SL.
PS. I have once saw a manifest stating US700 per ton for those base oil III. Yet fully synthetic oil (without POA) here is USD40 to USD50 for 4 litres vs just a bit less of USD 30 to 35 for semi synthetic blend. Food for thought. 🤔🤔🤔.
Looks like CASE driven milage mandate was not discussed and the push on using 0w 20 engine also starts hapoening over here after 2016. Before this the same Honda car model is using 5W 30 or 10W 20. Also suspect that this is in parallel to more and more amount of highly hydrocracked base oil III coming into the market.
Not sure how this are tied up to issue of cars in USA having high oil consumption just after 20,000 miles on the road. Regards.
