    My Blitz FLD meter has 2 individual digital LED readouts, the gauge is connected via OBD & external sensor for the oil pressure. I have mine set to read both oil temp & oil pressure but I could switch from pressure to engine coolant to see what the difference is between the 2 temps although I'm pretty confident the engine coolant is always lower & always well within check of about 90C if memory serves me correctly. I could also log the info to be certain but sure the cooling system is pretty much rock solid.

    @ZZT86 Apologies for the thread necro, but you seem to have done some legwork on the oils for e85. I've just recently switched to full time (and daily driven) e85 in Melbourne - what do you recommend? I am currently using Penrite 10 Tenths Racing 5 fully synth 5W30, changing every 6 or 7k. I drive it fairly hard and track it whenever I get the chance (sadly only been 4 or 5 times a year but looking like I can start doing more).

    I'd be grateful for your opinion!

    Bloody oath ! What I have found (which makes sense) is that a good tune & driving habits will give you oil longevity, fuel dilution will kill your oil. For E85 I highly rec the latest oil spec which is SN/GF5, 5W30 for hard or track is good, perhaps even a 40 weight depending on how hard you drive. Personally I use TGMO - Toyota Genuine 0W20 which has been the subject of some great & interesting discussion on BITOG - this oil is supposedly amazing ! I do not track or consistently drive my car hard though.

    I suspect the Ten Tenths oil is specced lower because of the high Zinc content which isn't a bad thing, you would have to confirm with Penrite on the oils credentials when it comes to the use of the juice or do UOA testing With plenty hard driving & track use I would dump it more often like every 5K kms max. I have heard & read that Ten Tenths is a mighty good oil for the track with great recovery from heat stress. Get an oil pressure & temp gauge if you haven't already aswell as a good oil cooler.

    @ZZT86 Thanks for the reply mate! RE the bolts on yeah, I'm going to chuck a catch can on next, then a decent oil cooler. From my research it appears that the Penrite 10 Tenths Racing 5 5W30 I use is very good for track use on e85, but not suitable for street use on e85 - simply because if using it you need to be dropping the oil every 1,000km or less. So I'm going to switch to Penrite ENVIRO+ Penrite Oil | ENVIRO+ GF-5 5W-30 (FULL SYN.)
    It's e85 safe and should allow me to have oil change intervals of around 4-5k while still driving hard. I'll probably do a couple of UOAs on it and post it here for some thoughts.

    ^^ I suspect what you meant was that as a daily the oil would self destruct from not enough heat in the oil whereas on the track it would get more than hot enough to burn unwanted fuel dilution & water if any hence it lasting longer. The SN classification is the latest & best to deal with ethanol & water dilution. It also helps to make sure the engine isn't running too rich to start with.

    The GF5 is fine, a fairly lightish 30 weight oil, monitor oil temps & pressures when driving hard, especially for extended periods.

    Here's a couple of ONLINE manuals I stumbled on recently and I find them useful for the plain language used and things I have not found in some other manuals.

    Toyota 2017 86 Repair Manual
    https://demos.starbase7.net/t3Portal..._rm_index.html




    For Collision repairs/ bodywork
    https://demos.starbase7.net/t3Portal..._cr_index.html
    -----------------------------------------------------------------------------------------------------------------

    One thing I found that puzzled me is it is stated under "Engine / Hybrid system" / FA20 lubrication / Oil & Filter / Replacement ( then scroll down to 6.ADD ENGINE OIL ) you will see

    Standard Capacity:
    ITEM CAPACITY
    Drain and refill with oil filter change 5.4 liters (5.7 US qts, 4.8 Imp. qts)
    Drain and refill without oil filter change 5.2 liters (5.5 US qts, 4.6 Imp. qts)
    Dry fill 6.3 liters (6.7 US qts, 5.5 Imp. qts)

    So I read it as if a dry fill needs 6.3 liters, there is 6.3 minus 5.4 = 0.9 liters of oil left behind when you do a change with filter. The penny finally dropped that there is 0.9 liters of dry i.e. air space DOH !
