I have heard a few mentions recently about Swepco gearbox oil and was wondering if anyone has any info about its use in Honda gearboxes. It seems very popular in the Porsche world, but I don't know if it is a great choice for an ITR Torsen LSD. Stuff that seems to be popular is the 201:

The website for most products is vague - was there something about the performance of the fluids that did you not like?
With a little research I have been able to find pretty good info about almost every fluid, oil, gear oil, etc out there.

It is hard to quantify or know for sure performance of the fluids. But I ran them and didn't have any problem for half a season.
Then to save some money and recommendation of people, I switched to Mobil 1 for the second half and managed to spun a rod bearing. Probably not because of the oil, but I don't know for sure.
After that I moved to Honda and used strictly redline until I see so many posts about people using Mobil 1 and switch to Mobil 1 again cause it is cheaper.
Managed to blow the K20A after 4 race weekend. No mis-shift. Is it co-incident? I like to think so. But the price of Redline suddenly doesn't look expensive anymore.
Been using redline oil for my 2nd session. I did blew one motor, but it is because of my mis shift. The other motor is 12 race weekend old and still going strong. Dynoed at 215 whp at Buttonwillow the last race. Which is similar with the dyno number on day 1.

Information in the net is a double edged sword. Lots of good info, but there are so many bad info, second hand info or bad data. The key is to filter them out.
IMHO, if a company expect us to do the leg work doing this kind of research, they are not worth my money.

This is very true - I like to use this forum:

Lots of high-tech, low-bs info

Thats one way to look at it, but I have had a hard time finding info from manufacturers
Maybe they do not want to publish the info? But its fairly easily obtained from fluid tests - I have been using castrol synthetics (the 'euro formula') and motul in the trans and brake system and had no problems
I'll be using motul in the engine when I get around to rebuilding it.

The gearbox for the Robinson helicopters use Swepco, even after we surveyed all available aviation grade synthetic and non-synthetic oils. The Robinson gearbox has teletemp stickon temperature labels that show the bearing housing temperatures reach upwards of 220 to 260 degrees. To date, there have been no gearbox/bearing failures on the Robinson R22 or R44 helicopters.

Are you using Castrol SRF in the brakes? Where do you buy it, and how much do you pay?

Motul 600 in the brakes - I love it. Flush it once a year and forget about it.

Not sure that I can answer your question to the "T", but here goes:
I've run Swepco in both Honda and Porsche transmissions and it made a world of difference in both gearboxes. Shifts were smoother, grinds disappeared. Both tranny's were LSD equipped but were aftermarket helical & not clutch type like the offerings from Honda, so this may be a point to consider.
From the Porsche forums that I frequent, I've been told this about Redline gearbox synthetic from Porshce autox'ers whose opinions I trust- it is stuffed full of sulphur compounds that will cake the gearbox components with repeated exposure to high heat. It was enough to get me to consider the tear down, clean up and make the switch to Swepco in both cars. FWIW, I've been happier since.

Great that is exactly the type of answer I was looking for. My dyno tuner swears by it as well.

Sounds like I can't lose trying out this Swepco 201 stuff. It is going in the tranny today! (I've got a ton more ponies now in the R and I was thinking I might need a little more fluid insurance. Mobil 15W-50 is in the oil pan and cooler) Thanks.
