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

I'm not sure what the h-tech variant is but in these cars you should be running the 8100 series full synthetic.

The 300v is NOT intended for extended drain intervals as they do not include the same additive packages that you find in the 8100 series which is intended for street use.

The Motul lasted through two seasons before I started noticing a drop in smoothness.

I'm not sure how many events you partook in but in road course track events we change out the trans and diffy fluid, even Motul once a season if it needs it or not.

Glad to hear the Motul Gear 300 worked for you.

The 8100 series has worked well for our clients especially those who have done UOAs after 6-8K miles.

Our clients use the 8100 for anywhere from 5-8K miles depending on their driving style is.

We have been alternating 300V 5w30 and Motul 8100 0w20 on our Project BRZ with 3000 mile intervals which includes about 2-3 track weekends during each of those 3000 mile intervals.

That's exactly what I said. The clutch style differentials use a friction modifier in the oil.

There is no need to use the motul with the friction modifier for LSD as the FRS uses a Torsen and has no clutch pack. Using it won't hurt anything but it isn't necessary.

Motul is a fad like wearing underwear is a fad.

Motul has been "in" for many years now. It only appears to be a fad now because this is a relatively new board and there are a lot of first time enthusiasts here. Motul has been good for a while and will continue to be

Also, OP, there are many many oil analysis and data on NASIOC for Motul. 300v is a true race oil and is a big deal in the tracking community around here. (Texas)

H-tech 0W-20 is primarily an Asian/Aussie oil. Compared to Eco-lite 8100 0W-20, it is thinner in all temps and probably has a lower High Temp High Shear.

Being that it is thinner and meets newer API/ILSAC specfications, I presume it is geared more towards better fuel economy over wear protection.

Ever since I did the Motul Gear 300 swap in my transmission and differential, I have noticed a huge improvement in shifting and smoothness with the car. I really wish I would have done this sooner than 18k miles. It is well worth and I believe that Motul does live up to a high quality product. Real road experience has convinced me over the past 2,000 miles.

Majority of driving is daily so I don't know how this contends with the track users, but I am happy with it.

LSD is an umbrella term. Torsen falls under that category. So do clutch style lsds, whatever they're called. Like the ones on old miatas

Gear 300 is good for the tranny especially when you're putting a lot of heat into the system. When oil breaks down, it becomes harder to get into gear. While Gear 300 doesn't have issues with heat, it sometimes feels a little notchy when it is cold. You'll notice there are always some compromise. OEM fill usually feels the best in the cold, but also begins to suffer in high temps.

Gear 300 LS works better for track related use for the additional frictional modifiers. It just feels different. It's not something most people will notice on their everyday drive.

Mike, correct me if I am wrong, but the Gear 300 LS can't be used in the trans because it isn't GL4 rated? Only the Gear 300 NON-LS can be used in the Trans, that's one reason we use the non-LS across the board so that we can put in rear diffy and trans without issue.

I was pretty specific in my post.

Sorry for the miscommunication. Gear 300 LS in the differential only. We use Gear 300 for tranny.
