Pennzoil makes the same synchromesh, whatever poison you choose, add a bit (maybe 10 or 15 percent) lucas oil stablizer All 3 of my manuals shift like butter - my old squarebody had a muncie 4spd I used the lucas straight up in that one
@@sarahknight4996, I hadn't heard of it either but there's a guy with a 650HP FK8 who uses an mix of the Lucas stabilizer, Torco RTF Tranny fluid and small small amount of Liqui Moly Ceratec. Swears by it. I guess it's a thing in super high HP applications from my research
2006 Honda Si coupe with 130,000 miles. Transmission (6-speed MT) started getting hard to shift, Amsoil Synthetic synchromesh 5wt-30 straightened it out. Now I'm considering Red Line or what this other post-kellismith- said about Lucas Oil Stabilizer at10-15%. Trouble with Amsoil is they act as if your order is not important to them- canceled my order for no reason I could ascertain. Just changed clutch master & slave cylinders & was thinking to do another transmission fluid change. Anyway, thanks for the video JT.
So, I was completely uneducated, and also, I’m wondering why everyone runs the FRICTION MODIFIED version of the GM (GL-4) 75w-80 Synchromesh MTF? It was designed for a transaxle that had a limited slip diff (LSD), which required friction modifiers/LSD additive. This means that it would be *more* SLIPPERY. Correct me if I’m wrong a bit, but don’t most manual gearboxes require a fair to big amount of friction, to be able to have the synchronizers grab/line up? Having more slipping/slippier gear oil/MTF would just cause it to grind, or you would risk or be near grinding sometimes, causing excessively notchy/“scratchy” feeling shifts? Now, I know that all the other ‘Synchromesh’ formulas out there are all supposed to be rated for GL-4 level protection, but even though the Penzoil Synchromesh is thicker than the Valvoline and other competitors I believe, doesn’t the label on the bottle clearly specify that it’s only good for up to **GL-3** specifications..? That would mean that it would shear and break down more easily with greater power level (GL-4+) type handling… Interesting how people are misleading others by saying that Pennzoil Synchromesh is almost the “exact” product as GM’s Synchromesh (supposedly the most common or “best” Synchromesh formula on the market). Of course, I think Amsoil, STP Driven, and BG Synchro Shift’s Synchromesh MTF formulas are much, much better than the lower priced ones. I’ve tried other generic GL-4 gear oils/MTF’s, ranging from 70W, all the way up to 80w-90, I believe; and this didn’t necessarily always help with the shifting issues (ex: fluid was either too thin for overly hot conditions, like racing and tracking; fluid was too cold for overly cold conditions, like deep winter storms/blizzards and near freezing or under freezing/negative temps).
tried it. very slick. had trouble getting into 1st. had to double clutch. put Honda MTF back in but feels so notchy after 5k miles of city driving. going to try MTL next.
i’m planning to do a clutch/flywheel replacement on my 2019 Honda Civic Si. Right now it’s stock and it’s slipping, i believe stock 10th gen si comes with Exedy Stage 1 clutch, planning to do Stage 2 Action Clutch with Chromoly Flywheel, i live in Cleveland Ohio where it has all 4 seasons. Which MTF should i go with? I do a little spirited driving when on the highway and curvy roads but it’s my daily, honestly i don’t mind the notchiness so i know Honda MTF is okay but is there any MTF you recommend? good for snow and summer driving? thanks
No civic si stock clutch pedal is stage 0 it feels like your pressing a gas pedal on stock clutch I have a stage 1 and it’s a 6 puck with springs and my tires chirp almost every time
I've driven 600 miles with Redline MTL so far, I'm liking how it feels in 40 degree weather and even 80 degree weather. It's very smooth and much better than GM Synchromesh FM and Honda MTF. I will make an update video at 3000 miles to see if I like Amsoil more or Redline.
@@jtworksoncars6341 so how’s the redline mtl going on your car now mate? I’m also thinking in these 3 gear oil. Which one you recommend for a Honda FD2.

ks, never heard the one about Lucas Oil Stabilizer before, how'd you puzzle that one out?

Thank you! I'm having this same issue on my 2005 Honda CR-V in the wintertime which has a 5 speed manual gearbox. I'm going to give this one a try!

how did it go?
@@Coco-qz7fn As suggested by another person, mixed Amsoil 5wt-30 gear lube with 10% Lucas oil stabilizer & the transmission shifts like a new one.

Yep, very accurate these fluids
Any update on this?
what about MT-LV ?
@@jayd1008 Never used it. I recommend MTL.
@jtworksoncars6341 too thick for my application ..I may mix the two
What about torco mtf?
tried it. very slick. had trouble getting into 1st. had to double clutch. put Honda MTF back in but feels so notchy after 5k miles of city driving. going to try MTL next.
the way you keep shoving ACDelco away any time you talk about it😂😆😆
I definitely did not like it at all. It felt great at first, but it quickly went back to grinding 2nd.
I have a 91 acura integra what oil should I get ?
Honda MTF should be used unless you have shifting issues with it. Redline works the best for me.
WHATS THE VISCOSITY OF THE HONDA OEM MTF?
About 6.9 to 7.5 cSt. It depends on if you're using Honda MTF or MTF II.

If you transmission grinds when shifting at 8000 rpm this ain’t going to fix the problem
Torco sells one too wonder how goos that one is
it's GL-5. had trouble getting into 1st. i'd go with the Redline MTL.
Amsoil here.

@@shenray337 Redline works the best for my car. If you're not having issues with Honda MTF, stick to it.
