Apr 1, 2003 10:40 AM | | Margura mineral oil vs Shimano mineral oil , whats the difference between the two? can they be interchanged? I have some hs-33 margura blood (mineral oil) left and i need to bleed my shimano XT disc . Can i use the magura fluid or do i need to use the shimano fluid. |

Apr 1, 2003 11:39 AM | | Mineral oil is mineral oil. Save a boatload of money and buy some generic at Wal-Mart. Works great. I'm using it in my new XTR's with no problems. A lot of bike shops use generic mineral oil also. |

Apr 1, 2003 12:37 PM | | That was my feeling as well,
thanks |

Apr 1, 2003 12:41 PM | | You obviously do not care about your personal safety or your bike. The crap at wally world is not the same, sometimes it will be thicker, that is very bad especially for disc brakes. The lines are smaller diameter, and do not flow fluid as fast......in other words your pads will not work as quickly as you might want them too. Use what is recommended by the manufacturer, and if a bike shop is not they are not an authorized dealer. And why on earth would you have already bled your new XTR's and put sh1tty generic fluid in them?????

| Agree... | JimC.
Apr 1, 2003 12:51 PM | | the wrong viscostiy = cr@ppy brakes. and yes, WTF didja bleed brand new brakes? I'm confused, unless you also resoled your new riding shoes at the same time.

| Agree... | bikerbike
Apr 1, 2003 3:57 PM | | My guess is he had to cut the hoses down and thus having to re-bleed.
So is magura blood the same as shimano oil? |
| Nope, Magura Blood is NOT the same as Shimano | JimC.
Apr 1, 2003 4:04 PM | | I'd stick to the Mfrs. spec or risk poor performance and problems. Jim MCM #11 |

Apr 1, 2003 5:37 PM | | It will void any and all warranties you had, Darrell may have saved some money but he will never get a warranty from Shimano, pity he is willing to spend that much money on a VERY sweet set of brakes but unwilling to spend money on some fluid that he will have to use once every two years or so. |
| It wasn't to save some money... | Darrell
Apr 1, 2003 11:09 PM | | First, I didn't use the generic mineral oil, my bike shop did and I was there.
Second, The Shimano warranty does not say that this will void it (http://bike.shimano.com/services/warranty.asp). Although the way their warranty is worded, they could get out of anything if they wanted to. For example, your warranty can be voided if you use the product for competition. They'll stand behind the brakes and if they don't, my bike shop will.
Third, It was used to bleed the rear brake due to needing to shorten the hose length.
Fourth, It's worked great for a couple hundred miles of technical riding so far. Both brakes are working fine and they both modulate equally well.
Anyhow, if you have any doubts, buy the Shimano stuff. |

Well:) ...the XTR disc brakes are sold as separate items. You have the caliper/rotor and the levers/hoses/cables/fluid set. To my knowledge they don't sell a completely bled set similar to other manufacturers. |

Apr 1, 2003 4:54 PM | | very unfortunately that stuff Magura and Shimano is using is NOT the same, and more unfortunately it is very expensive to boot. They have to pay for that advertising after all.... :-(
However, the fluid is mixed just right with the correct viscosity in cold weather and hot climates alike. It has antifoaming properties, just the right amount of lubrication, and maybe even oxidation prohibitors for the alloy parts inside the brake.
Furthermore it is tested not to abuse the delicate seals.
Of course it comes out of a 55 gallon drum and gets refilled into little bitty bottles with a nice little profit. But besides throwing any warranty out of the window, you risk your life, when trying to save a few bucks. So go with the correct stuff, no doubt.

Apr 1, 2003 8:02 PM | | I'd be using fork oil.
It contains viscosity modifiers (to keep the viscosity reasonably consistent with changing temperature), frictional modifiers (slippery stuff), anti-foaming agents, is available almost anywhere in a variety of viscosities and is a whole lot cheaper.
Anything else becomes a battle between you and your wallet.
I've found (in suspension) standard hydraulic oil changes viscosity too much with temperature. ATF would be the fluid of choice but it may be too thick (between 7.5 and 10wt) for a good lever feel.
I take most seal warnings as scaremongering. There are very few fluids that'll eat your seals (DOT fluid is one).

Apr 1, 2003 9:23 PM | | If you are worried about a warranty, which if you just bought the system you should be, then I'd be using what they want you to use....that being said if you bought them you can do as you please. I'd always used 5wt Finish Line fork oil..... but now Magura has their Blue Blood which is better in Magura brakes....it really does work better. I've never used Shimano brakes so I can't say much about them.....but I'd bet that Finish Line would work in them as well. |

Apr 2, 2003 12:47 AM | | It's interesting how paranoid people are about warranty stuff.
I think the only warranty claims I've had were regarding ball bearing derailleur pulleys which seized (3 months dry riding) and gloves which literally fell apart.
Remember a warranty is for "defects in materials and workmanship". The time period a warranty is offered for doesn't actually matter, if it's really a screwup it'll die early otherwise it'll last for a long time.
I also think the majority of warranty claims worldwide (in all industries) are caused by idiot users and mechanics. The last shop I worked for had a whole bin of warranty stuff. I think I salvadged 3/4 of it simply by knowing how it worked.
Often the warranty claims that reps allow are to satisfy long term customers and not because the product was faulty.

| Oh very true | Pat T.®
Apr 2, 2003 4:27 AM | | Only reason I brought it up is because if the caliper say was sent in to be checked, and it did not have the right fluid inside....you get the idea. Like Darrel said the warranty is worded so that they can get out of it. But this is like beating a dead horse wiht a dead horse, I just want people to know that "IF" they are worried about it it could void it. |

Apr 2, 2003 5:01 AM | | I can't really agree with the "The time period a warranty is offered for doesn't actually matter, if it's really a screwup it'll die early otherwise it'll last for a long time."
I found a fault with my rear Magura Marta lever after about 6 months when I switched to blue blood. The lever had no braking point when applied very slowly. The other fault I discovered after a years use during the winter. It turned out that early Marta brakes came with an incorrect durometer hardness for the piston quad seals. They took excellent care of me in both cases. |

Apr 2, 2003 4:48 PM | | By time period I was meaning some manufacturers "limited lifetime warranty" versus others "one year warranty".
The difference in consumer protection is nothing. If your Marta's only had a 6 month warranty I'm sure your seals would have been taken care of a year down the track.
