Anyone use Castrol Edge 5w40 fully synthetic? :)

 

no thats a bit to thin for me! i use a 10w

 

dan.:biggrin:

i will only ever use Millers CFS 10w 40

The opieoils website recommends 5w30, so surely 5w40 isnt too thin.and the viscosity when hot is surely the same as 10w40, as the 40 bit is the same......or am I missing something?. :)

Not the great oil debate again, It's all down to personal preference.

I have opie oils 10w50 ester Fuchs ready to go in mine :wink:

have seen the long winded threads regarding oil.......would just like a simple yes or no as to whether 5w40 fully synthetic is ok :)

i had semi synthetic 5w 40 and when i took to zedworld they replaced with a thicker oil, and she sounds much better.

No, you're spot on with that mate!!

 

As for the 5w30 - that is too thin; Nissan recommended a 10w40 originally so the "40" part is most important. I'd certainly not use a "30" rated oil in a 17+ year old twin turbo engine where engine compartment heat is a major issue!

 

So to answer the original question; yes Castrol Edge 5w40 is just fine for a 300zx.

No worries mate - I've always used a decent 5w40 fully synthetic and it's just fine!!

might have been 5W30... I can't remember... all i know is that it was too thin.
