In my tomei i use Castrol SAF-XA 75W160 i think its about $27 a litre. I originally used some motul stuff however my 2way was really noisy and clunk heaps when i got told it would be one of the quieter 2way's. Also alot of my friends who drift all use penrite limslip which ive been told is good for much cheaper

Anyone using redline shockproof heavy?

Have used it in previous cars yes. Its the ultimate in shear load protection...

If you really want the low down on what Redline product for what application, give Tim a ring at WestRacing on 08 94461913. He's full bottle.

On the oil change interval. Well - how long is a piece of string I guess. Depends how hard its driven and what parts are getting loaded the most.

A 6 sec Drag car throws away the oil after one race meet (or more!) even if the oil is untouched.

For me, I'd prob check the diff oil at 5,000km and 10,000km to see how its fairing. If it looks good I'd be happy to leave diff oil in for 20,000 to 30,000km no probs if its a good oil.

A race car probably wouldn't...

Let's face it though,

No one ever did any harm changing their oil a little more often than needed. So if you can afford to change it more often - do it.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
