i use Amsoil for all fluids.

 

I use Motul RBF600. Wish we could get Amsoil DOT4 up here in Canada, I`d love to give it a try

I believe the Super Blue is pretty good as well.

 

yeah i use amsoil for everything but brakes right now. i think im gonna stick with the super blue for ow just because it would be a pain to do a complete changeover/flush as oppose to a refresh right now.

the other thing i have to think about is oil...the last analysis i did on the amsoil 10w30 came back a little thinner than i would have liked. but thats a whole nother discussion.

 

Are you using the regular 10W30 Synthetic? I would recommend going to the 10W40 high zinc.

 

Have you tried ordering from the vendors on here?

 

Yes. It can't be imported into Canada for some retarded reason. -.-

 

I use motul 5w40, redline mt85, diaqueen lsd, super blue. The super blue is mainly cause I haven't made them overheat yet and they last much longer than the motul variant. I do a full flush every season switching between type200 and super blue.

In the winters I switch engine oil to amsoil 0w30. Sucks doing many oil changes in the cold.

 

yea currently on the regular 10w30 (AMO?). analysis came back nice except for reading closer to a 20w. I had done a ton of tuning pulls, as well as the sample sat in the container for ~3 weeks before sending it so i had expecting some fuel dilution, but it seems it wasnt that. i thought i only saw the zrod in 10w30 on the site? i had been planning to up to the 10w40 this season anyway, since i only have one change of 30w left.

good to know you havent boiled super blue

 

IMO you should try super blue first. Don't go for the higher temp much more expensive fluids until you manage to boil super blue. It just lasts so much longer and is so much cheaper than motul (which is the next step). The problem with the uber grade brake fluids is they tend to pick up moisture easier and that reduces their lifespan in the system.

One thing to mention though....super blue stains your reservoir and brake system with that blue dye they use. If you're OCD and don't want the permanent blue stain on the components use ATE type200. Its the same thing....just without the blue dye.

Nevermind...

 

yeah i ran rbf600 in a previous car.it was definitely pricey, and went bad on the shelf very fast.

didt know you could get the ate without the dye. i dont mind the blue tho lol. reminds me what fluid it is

 

Now while I'm sure I use my brakes a bit harder than most of you guys do, I would never wait until after I boiled fluid before I decided to upgrade brake fluid. When ive boiled the brake fluid my pedal has slammed to the floor with no brakes at all for that first pump, why wait for that to happen? If you're lucky you may just get a soft pedal and have to come in and bleed the brakes before it happens all over again. I run SRF the entire season without needing to bleed them even once (although I do right before the Runoffs just because) I had to bleed super blue after every session, that goes for the Motul as well. Brakes are nothing to be cheap about. 1 quart at the the beginning of each driving event/racing season and you are good to go. A side benefit is your pedal feels more stiff and is easier to modulate. If you are never going to be maxing your cars braking system, ignore everthing I just said. And no, I don't have an SRF sponsorship

 

im open to any and all data points, as i have no actual first hand knowledge on track use of anything discussed in this thread.

that being said...i would be amazed if i boiled super blue in my first one or two hpde's personally.

the dry boiling point is ~60F less than srf, but the srf blows it out of the water (bad pun) in wet boiling point. so i think that would explain the lack of needing to bleed it.

my tentative plan is to revisit fluid choice in june at the same time i will be doing ss lines. the way the schedule is, i am hoping for 2-3 hpde's in april/may and then theres nothing in the region until almost august. will give me time to hopefully adjust any weaknesses i find.

 

Last time I boiled brake fluid I realized my pedal was getting too squishy and came into the pits, at which point I couldn't stop my car and had to use the hand brake . But warning signs will definitely be there. For something like fun track days as long as you're aware you are unlikely to completely loose braking all of a sudden. In competition though I can see it happening.

I have been in my friend's car though when he boiled his fluid and lost all braking power. Pretty scary. He just used as much engine braking as possible, cranked the wheel and hoped for the best. Turned out ok cause we're both still alive. You only need to boil fluid once to be very aware of the warning signs.

 

Youre right, you should be fine your first few events. I was more talking to the others reading this post and for you in the future. Great to see more Evos getting out to road courses!
