Is this Oil ok for my rebuilt Performance Engine

Hi All
So the engine was run in on the Dyno and the oil was replaced after the Dyno tuning with a cheaper quality fully synthetic oil, have done about 1000 k's on this oil and want to now replace it with a good quality Oil.
Any way currently tuned at 18psi boost and pushing 366Kw on E85 Fuel.

I currently have 5L of Castrol EDGE 0W-40 A3/B4 Titanium FST.

so want to know if this will be ok specially with E85?? and a new performance engine??

 

Too thin for our climate ........

Suggest you use 10W-40 now that you have a new motor

 

Use whatever engine oil your engine builder told you to use.

 

10w/40 with regular changes on E85

I like to use 15w/50 with E85.

 

Unless your builder does things differently to the majority of VGs it's unlikely there's any reason to go 0W in Australia. 40 or 50 hot is usually the go, depends a bit on clearances but if it's driven in anger and doesn't have a big oil cooler probably 50.

0W oils cop some extra limits on zdpe and stuff so wouldn't run them if not necessary.

 

Wouldnt go 0w40, far too thin. I run Penrite 15w50 in my dedicated E85 zed.

 

Thanks

Thanks for the advise, picked up some Penrite 10W40.
Will change it out regularly, more than likely on a time bases as it rarely gets driven these days.
