ok so after scouring the various subaru threads and listening to the pros and cons of running this stuff I'm gona try some in my gearbox

Despite Redline's own information saying that it's not suitable for synchro boxes I see a lot of people are still using it and by all accounts it's performing well including Mike who's had it in his RS box for 3 years no problems.

So enough research, enough reading I'm gona try some and I'll let you know how it goes

Only problem is this shit's gold so I can only buy a few bottles at a time lol and that's even thru the BNT BC5 account

If you take the part number written on the bottle and change it from -1 to -4 you'll get a 4 quart bottle that is cheaper IIRc

Ill be interested to see what kind of improvement you get

sure I'll let you know how I go

The whole 'not suitable for synchromesh" thing may be the type of fluid used, it might react with yellow metals, I.e. Would slowly dissolve your synchros into pulp over time. The kind of time period where you would notice no harm in the first year or two, long enough then go around spouting on the internet that it's all g.

I'd advise you check why they say it's not good for synchros.

Sorry to be a downer, but physics is physics

It is a great syncro bandaid until you replace the box though.

i did so much research my eyes were going blurry lol but I did come across this post on NASIOC from a Redline rep which gave me some confidence that the 'synchro effect' could be a myth and they are unlikely to be affected. Combine that with the many accounts of people running shockproof for extended periods of time in their boxes with no problems (boxes with pumps and filters not recommended) and I'm game to give it a go!

sounds good to me!

Cool, if it's safe on the yellow metals, then mint! No problems.

My experience has been fine so far. I've had it in the c56 in our fx gt for about 3 years and it noticeably improved the syncro action on 2nd and 3rd. I've seen no side effects yet. I also have it in the RA which had virtually no syncro action at all in 3rd and now is just a bit notchy. It does look like Jif and I wouldn't be surprised if it has that effect on the syncros but it does seem to be a good short to medium term solution. Although if you're planning to rebuild the box later I'm not sure I'd want to be the one cleaning out all that green gunk.

that's a great bit of real world info right there and it lines up with the experience of others running it.

Agreed it is gunky shit even when it comes out of the bottle!

[DCVR]

found a bit more info...

[Leufkax]

The internet says many things. Also it doesn't actually get cheaper for a 4 quart bottle which is why most places just sell it by the quart.

So back to the soundproofing.......I'm very happy with the result so far. My efforts have defo reduced the drone and airbourne noise getting into the cabin.

There are more improvements to be had but so far so good

Here's to no more bleeding ears!
