Hey guys I have to do a bit of a drive tomorrow and was checking my fluids. Question is can I top up my clutch master with this . It's been sitting un open for a few years.
I wouldn't use it, oils do go off after a while, it may look fine, but it's quality may have deteriorated.
After approximately 60 years of association with "things Automotive", I would have to respectfully disagree with the above advice. Unopened(sealed)containers of Mineral oils are extremely unlikely to be "contaminated" in ANY way by the passage of time. Brake Fluids are similarly impervious to such problems UNLESS they are opened(as they have a propensity to absorb moisture/water, over time). A "sealed" container is highly unlikely to have suffered any such contamination.:br:
The keyword is ''clutch fluid''..... The rigours placed on a clutch fluid is only a fraction of that placed on the same fluid when used in a braking system. I use normal, everyday brake fluid in my clutch MC..... but I use high temp Motul in my brake MC The Motul is over 3 times the price of the Castrol fluid, so why waste money on what is not neccessary (plus the Motul is hard to find)
Yep, clutch is so simple, assuming that bottle lid was kept tight and it hasn't absorbed water over the years, good to use.
I agree with the above. It's good Aslong as it's sealed. I've actually tested brake fluid bottle that wasn't used for 3 yrs and who knows how long it was shelved for aswell. Tested perfect. (Brake fluid tester probe type)
It is the same thing as if you would buy same bottle of oil in some small country town's petrol station... Where seering fluid doesn't get used on daily bases...
Thanks guys I ended up using it and drove to the airport and back yesterday with no problems Thanks for all the replies
It is rare for the clutch fluid level to go down enough to need topping up unless there is a leak. The most common places to have a leak: Slave cylinder Master cylinder Hose/line from hard pipe to slave cylinder Leaks never improve, they usually get worse over time. Left unchecked you could find the clutch pedal drops to the floor when day as you push it in.
yeah true but if you have a look at my other thread last week you see the dramas iv had with replacing this and that ect ect hence the drop in fluid.
DOT4 In the clutch slave cylinder if unopened should be OK. I would not use it in the brakes master cylinder because I am fussy about using old brake flued in brakes.
Hi Bob, with the greatest of respect, I would suggest that with ANY such product it would be almost impossible to ascertain the "age" of the product at time of purchase(you could be buying Oils that are "years old" at the time of purchase). P.S. I am also "fussy" about the products I use.:zlove::br:
