    I've used LMA in the RX7 and find that it lasts at least half a season without even having to bleed the brakes. Of course, my car's fairly light too, but at about 2150 lbs without driver I don't think olive oil would work for me. Also, the Extra Virgin olive oil is probably more expensive than LMA.

        I've also been using Elf Frelub 650 for the past year and it's the best I've found so far. Before the Elf, I was using Motul RBF 600 but for my car the Elf works better and it's cheaper.

          New (to me) rumour: I just heard that Motul has a new 660 (650?) degree fluid... should be priced about 33% more than RBF600...

          I wouldn't consider that a quote.

            True, but lower wet boiling point. I have yet to cook the 600, so I won't be switching anytime soon (espcially at higher cost ... it's about 50% more as far as I can see).

                I think Chris bought his through Northern Performance (Pete Mills). I will confirm this shortly with the price.

                  Dave, Elf isn't the easiest stuff to find. Pete Mills @ Northern Motorsports sold me on the Elf and I've found it to be the least compressible of all the fluids I've run. I actually noticed a pedal feel change just driving on the street. That alone sold me on the switch. The slightly shorter pedal travel really helps with the heal-toe in the GT.

                  Price is less than $25 give or take for a 1L container.

                    The RBF660 is available and carries a revised price. I have been using it since July but quite honestly I never had fluid issues with the RBF600, so the 660 is like extra insurance.

                    Most Quebec racers have been upgrading to it because it is available.

                      Last season I put in the 600 in the spring and never touched the fluid for the entire season. Saw no reason to - must've had 30 events on it. Even towards the end of the season peddle feel stayed the same. Think I'll try the 660 next - I like over-kill.

                        Actually, the Frelub 650 is about $15.00 per L.

                        I have to admit, I am a convert from Motul. I had been using the ATE recently with pretty good results, but always felt the Motul was better. I just did not need the Motul the last couple of years, as the ATE had done its job.

                        I have not been able to get a good enough brake pad into my car for the last 2 track days I attended. I had only gotten HP+s in the car, and a track day just puts too much heat in the fluid, from not enough pad. Hawk has been out of the Blues for my car for a bit, but they are here now, so they will go in for the next track day.

                        So, for the last day I was at TMP, I did a fluid flush with Motul RBF600. 3-4 laps and the pedal was going away pretty seriously. Never hit the floor, but was close. I assumed that it was simply the pads going off, and suffered. I would back off, and let the brakes come back. The pedal never really returned to its correct height and feel, even after a week on the street. Barely acceptable for a lapping day, not even close for competition.

                        For my next track day, at Dunnville (a track that is harder on brakes), I figured a fluid flush would be in order, to see if I could get the pedal back. Since we had the Frelub 650 in stock, I switched to it. Much better pedal instantly, and its performance on the track was much better.

                        Even at Dunnville, the pedal never went away, and the fade could be attributed to a lack of a race brake pad. I drove away from the track with a rock hard pedal, and no increase in travel as compared to the drive in.

                        Yes we sell the Elf, so my opinion may be biased, but the RBF600 just was not up to the task. I would expect that the RBF660 will be an improvement. But, the Elf is cheaper, from what I have heard.

                        Lastly, there is another race fluid from Elf, called the HTX, which is $23.00 per 0.5L. Not as good as Castrol SRF, but a step above any other fluid, from what I have seen.

                          I suppose every car is different, as well as braking style, but this seems really unusual. I have never heard of anyone being able to cook RBF600, unless there was some sort of problem. I have certainly never had any issues, and I do what Miles does ... flush in the spring, and forget it for the season. I have a few bottles of SRF, so maybe I'll give that a try, just for the hell of it

                            Really? I have seen it done a few times over the years, each time with not enough brake pad. I believe that one should run a race pad on the race track. When you over-tax the braking system when you don't, the fluid is the part that gives up.

                            Usually a novice will not be the one to put very good fluid in their car. So, by the time someone is experienced enough to change the fluid, they also change the pads.

                              Good point ... crappy pads will overheat, tranferring the heat to the fluid, which I guess cooks it. I guess I haven't seen too many newbs using RBF then

                                ive ran year old RBF fluid on some PRB Ceramics this season.

                                DDT i would get fade but firm pedal after 5 laps, shannonville i had no problems..

                                then again, as always, i dont brake much.
