There have been a few Zeds with broken engines recently, mainly bottom end failures it would seem.
In general the question of oil level is bought up, but not what oil are you using.
So with anyone with a broken zed like to contribute to what oil they are using.
I am using Castrol Edge 5w-30 fully synth, when i told a good friend of mine who is very experienced with Skyline tuning he said instantly, get it out of there, i wont repeat the rest, lol. He explained further with examples and made note to a tuned R32 which he did an oil change to using Edge. By all accounts oil temps were a good few degrees higher immediately after changing, did a few 100 miles and wasnt convinced so swapped it out, i cant remember what he said he used (Motul i think) but did say oil temps were back to previous readings and the Edge he took out seemed to be very thin and contaminated, like a flushing oil.
Not looking to get into a Edge is fine battle as it came recommended to me by Opie and i am sure they know their onions, but i would be curious to members recent failures if they want to contribute.
