Hi guys,
I have a flex tune on my GTR and have been running e60 (as per ethanol sensor) and and it's down to less than e5 as I've used 98 on the last fill.
My catch can breathes to the atmosphere and have noticed since using ethanol that a small mist of vapour escape the catch can (it basically feeds off the 2 cam covers and vents underneath the car, no filter).
So I called my tuner and he said it's totally normal as ethanol attracts moisture. I then have my mate who races a GTR suggest I only use 98 as he has heard horror stories of race engines that have sat there for 8mths then cracked open and needs a complete overhaul.
My question is am I just being paranoid and do I need to take this on board? If so, oil change followed by emptying the catch can and then 98 only.
I start the car every 2 weeks when I can...I also wonder if moisture has entered the engine or oil? Then again, the catch can is just doing it's job by way of removing the crap moisture.
I'm keen to hear other ppls thoughts, ideas and hopefully some first hand experience
My GTR absolutely luvs ethanol!!!
