Is Motul just a fad? Or is it chemically superior?
 

Society today is plagued with buzz words and trends. Things that say "Organic" fly off the shelves regardless of their actual ingredients. All of a sudden "gluten" comes seemingly out of nowhere and now half the worlds population is allergic to it. Crossfit, apparently just a competition to see who's the best at working out, is covered night and day by ESPN.
So my question is; Is Motul chemically superior to Mobil 1 or any other Full Synthetic? What about Amsoil or the other "race" oils? Or are we all just the protein powder meatheads dropping barbells at the gym?

Please calculate your responses. I'm not looking for "I know it's better because some guy I know who races cars uses it" or "Everyone on the Subaru forums uses it so it's gotta be good". Real data. Oil analysis.

Well its definitely not fad if you were a long time Subaru driver like some of us on here, people have been super into Motul for the gearbox and rear end at least since I first got my WRX back in late 2005 and it still just as popular.

So that's at least 9 years that I know of personally. I've seen posts dating back 14 years on NASIOC talking about Motul fluids.

Real data, oil analysis? I can't provide those. Only my in-car feels after using different brands. I wouldn't say they are way in above superior to everything else on the market. I'm mind of the mind that certain formulations work better in certain set-ups, for whatever reason. Motul Gear 300 works excellent in the twins' manual gearbox and diff. I've driven one with Amsoil in the box, and it was definitely better than stock, and pretty on par with Motul 300. I tend to use Motul in my motorcycle too, because of good experiences with it. On the contrary, I haven't always had the best of experience with Redline, for whatever reason. So for that, I stick with Amsoil/Motul for my vehicle fluids. My Camaro was Mobil1 for engine oil and Amsoil for gears, because that worked well there. I don't have any numbers or anything, just how the car felt with different fluids.

Its currently the "in" oil... it'll change in a few years again. it was Royal Purple and then Redline and then AMSOIL and now everyone is jerking it to motul. They do make some really good brake fluid and I plan to use their gear oil in my transmission but thats because it just happens to meet my needs for now. Royal Purple went in my mustang diffs because it had friction modifier in it already and was cheaper than buying everything seperate.

Motul is the real deal... It has tested higher then any other "conventional oil blends" IE: no snake oil additives.

here is the article and list of all oils at the bottom. http://540ratblog.wordpress.com/

Does anyone know if the Montul gear lube eliminates or reduces the rear end chatter associated when accelerating from stop on sharp left or right turns?

Yes. I used to get chatter on stock fluid, and it's eliminated once I put in Motul Gear 300LS.

I've never tried the regular Gear 300 in the rear diff, but I heard it might still chatter. Gear 300LS is what you should use.

Thanks. Ordered the regular Montul 300. If this does not eliminate chatter, will try the LS.

We used Blackstone Used Oil Analysis on multiple vehicle platforms over the past 8 years to validate our findings and experiences. We'll stick to Motul because it works for our application. Everybody has their own preferences for different reasons.

Why would a Torsen diff need oil with a limited slip additive/friction modifier?

Torsen T2 differentials are all gear driven.

Differentials that use it are usually Clutch type limited slip.


I changed the transmission and differential oil in my FRS a week after I bought it. The motul gear 300 did make a difference for cold driving. I never had any complaints when the transmission was at operating temp

I never had the chattering problem but I only had the factory oil in for a week.

My diff would grumble on the first turn after sitting overnight then made no noise, but after running the Motul I don't get the "first turn grumble" and more.

Motul in my trans fixed the 1st to 2nd grind that I had, especially when cold.

Interesting read!

^ These are just a few. The 300 will be fine in the rear diff, but the 300LS might be better.

Too bad that "test" has zero relevance to how an oil performs inside of an engine.

Motul is no fad though.

Founded in 1899 in New York, the Swan & Finch company started its activity in the sector of high quality lubricants. As from 1920, it turns to the international markets by exporting some of its portfolio brands like Aerul, Textul, Motul

There are some uoa's on 300V in the long uoa thread on this forum, but your questions cannot be answered by a few random $30 uoa's. These types of uoa's are very limited in scope and should not be used to judge oils. Motul, Mobil1, and Amsoil all use the finest base stocks and additives available and they all make oils that are certified by the API as well as making race oils.
