HIGH MILEAGE Motor Oil - Is It Actually DIFFERENT?

How much of what's on the label is marketing versus science? We analyzed a bottle of conventional 5W-30 Pennzoil, High Mileage 5W-30 Pennzoil, and Pennzoil Platinum 5W-30 Synthetic to find the differences. Watch as Certified Lubrication Specialist, Lake Speed Jr, reveals the findings. The results are quite interesting...

Who is the ​⁠ @themotoroilgeek ? I'm a Society of Tribologists and Lubrication Engineers Certified Lubrication Specialist and Oil Monitoring Analyst (I've maintained both of those for over a decade). I also worked for Joe Gibbs Racing for 12 years as their lubricant specialist. During that time, we worked with Wix Filters (one of our sponsors) to test and develop filters for our race engines. We also worked with Lubrizol and Chevron-Phillips Chemical to test and develop oils for our race cars. Following that, I was the head of R&D for Driven Racing Oil. During that time, I formulated and tested over 50 products. We also worked with Cummins, Comp Cams, Oak Ridge National Labs and General Motors on various R&D products. Those efforts are recorded in peer reviewed white papers published by SAE International and ACS Sustainable Chemistry journals.

I graduated in 1984 with a degree in Chemistry. I absolutely love stuff like this. Thanks for taking the time to produce these vids.

A lot of this went over my head, maybe a chart at the very end to see the differences back to back on the three oils might have been helpful

[toddervin]

I started using Pennzoil Platinum full synthetic platinum after watching Project Farm videos on the best oils. This confirms his findings.

I started watching these videos yesterday. I've learned more about oils in the last 2 days than I learned in the last 15 years. I love these videos

[ryszardbyczyk]

In the transportation business, mainly as a mechanic, for almost 46 years, and I never thought I would find motor oil so interesting. Thanks for another great video!

[naruttaanime]

So happy you teach us to learn chemistry without being afraid. I actually learned a lot. I wish all the science teachers could warch and learn too.

Good advice here, very thorough breakdown! I was very young in 1963 but I remember my dad got a tutorial from the local Ford dealer as he was handed the keys to the baby blue Country Squire. Quick first oil change, vary highway speeds, don't race rpms especially when cold, 'baby' it from a stop. (trans care was mentioned too) After 3, 000 miles he could relax but still change every 3 to 3, 500 miles. The engine was a 260 v8 I remember from the cool front fender logo. Great car that served for many years until Pennsylvania road salt finally ate the body and wood grain.

I'm an average gear head and have tried to watch/listen to other reports on the subject, almost fell asleep a few times. You my friend, I could listen to you for hours on how to tie shoe laces, great video, been using Platinum 5w30 in everything for a long time. Thanx for quantifying my choice.

[bobirving]

Wow, thanks Lake Speed Jr!!!
That was better than a college class and the info kept coming, firing on every cylinder!
I appreciate you hammering the point about “don’t need high TBN!”

[Duchydog]

Great job again Lake! Really appreciate your professionalism and passion to educate the masses on lubrication. Many thanks!

[btw]

I’m only 5 minutes in and already love your TBN/SP opinion. First I’ve heard someone explain it like that instead of poo-pooing the new oils.

Pennzoils new SP /GF-6 rated synthetic blend & full synthetic engine oils are best overall "off the shelf" oils you can buy today. Period. There use of GTL base stock is cleaner & more pure than refined mineral oil base stocks in all OTHER premium oils such as Mobil1, Castrol Edge etc. I've used Pennzoil Platinum / Ultra Platinum in my newer GTDI Ecoboost F150 trucks w/ excellent results. Used oil analysis by Blackstone Labs showed low wear metals present always/overall outstanding engine cond @ 168k mis on my '18 F150 Lariat FX4. Thus im running Pennzoil Platinum in my '22 F150 XLT Tremor w/ OEM Motorcraft filters. -NY

*_I noticed my 97 Honda Civic rear main seal dosent leak as much ever since I switched from cheap conventional 5w-30 oil to fully synthetic high mileage penzoil 5w-30. I can say it actually works!_*

[brandonupchurch]

The Pennzoil platinum may also contain ashless anti oxidants and organic friction modifiers that may not show up on any type of elemental analysis, consider another big part of Dexos1 Generation 3 was lowering the ash threshold from 1.0% to 0.9%. Also having less moly in the the full syn may be that the blends are using a dinuclear type of moly while the full syn is use a trinuclear variety which is more effective in a lower concentration.

Thank you, people don't realize how lubricants make such a longevity difference. Even important in the days of hand cranked bulk dispensers into tin capped glass bottles.

[robertos]

Looking forward to your observations after running the Synthetic in your Porsche. Always interesting videos, THANKS!

[michaelcinaz]

I can tell you from experience, these are all very good quality oils. The first 75, 000 miles, almost every single oil change was Pennzoil 5W-30 conventional. After that I started using Pennzoil 5W-30 high mileage oil. Normally use a Bosch premium oil filter or other premium filter. I’ve never tried the fully synthetic. I change my oil every 4000 - 5000 miles. I have a 2007 Toyota Tacoma 4.0 V6 with 145, 000 miles that I bought brand new, and it still runs like brand new. It’s very easy changing the oil myself.

Great Video I work for SHELL and the site I'm based out of is the largest ALPHA OLEFIN Producer in the world so some amount of what we produce ends up in Motor Oils. I also worked at the GTL Plant in Qutar and it was a very impressive place. The size of the Rotating Equipment is quite impressive especially in the Oxygen Unit, since the front end of the conversion requires tremendous amounts of oxygen. Looking forward to more videos.

[.Slomaro]

Started running penzoil thanks to project farm oil video from many years ago. Was impressed how it was just a few points behind AMS oil.

[stray]

I pretty much have no clue what you were talking about through this entire video. But what it did make me realize is that oil is complicated and that I need to stick to whatever oil the manufacturer recommends and change it often.
