Hi,
has anyone experienced going from regular clutch fluid which has caused problems to a better clutch fluid like Motul 600 and clutch problems getting in gear etc went away?

I used RBF600, no gear issues but my slave died in about 4 years and 5k miles... not sure it was related though.

you need to confirm the components (seals) of hydraulic system is compatible with the fluid.

I have used Valvoline synthetic DOT3 fluid in my new McLeod hydraulics for several years now without issue.

valvoline synthetic DOT 3/4 gets recommended a lot for its decent boiling point but superior lubricity. i think Tilton specifically calls for this fluid to be used with their hydraulics.

i've used RBF600 with no issues though.

I’ve made the switch and never seen a difference on day to day and drag style applications. I HATE that the common fluids all destroy paint. I recently learned that DOT 5 is silicone based and paint safe. For that alone Id switch…

Doesnt the 5.0 silicon cause problems with the seals?
2nd night out with 600 fluid and shifts nice

Don't' believe so... I was told by a "racer" that is is spongy compared to the standard race spec stuff. IE it can compress quite a bit more. But for a drag and drive style application, I don't think it matters a whole lot.

Nope happened again with 3rd to 4th shift felt strange ended up in 6th. Wot to only 4500 in 3rd.

The (temporary) improvement probably had more to do with having fresh fluid and having bled the system than which fluid was used.

If I had to guess, I'd say you have a leak somewhere where air is getting into the system. Could be the slave (likely), the master (less likely) or the lines. If the lines were leaking you probably have visible signs of wetness along the lines.

Hi,
not using fluid though

Yes it’s a related issue. High temp fluids are much harder on seals and will shorten the life dramatically. Stick with the Valvoline dot3/4 mentioned here. If you’re having a temp issue, work on shielding the line rather than a high temp fluid.

Hi, i suggest you should check and confirm the components

I've used Wilwood EXP 600 brake fluid in my clutch systems exclusively for a decade and a half and nothing has ever leaked, never had a seal go bad in the system of two different cars. I also use it as a brake fluid, same experience.
