You got any info which shows it's not? Happy to learn more... The article posted on the RP site suggests that it doesn't but does it indirectly... but all the other wisdom on the internet (and yes i know the net isn't the best for info) suggests it has plenty of esters in it...

I've just shot an email to RP themselves for an answer... Will let you know of their response...

Guys I swear I lost hp and tq with Royal Purple 5W30 with this engine. and from what I have heard the 350Z HR guys have quoted the same. This stuff works wonders for the old VQ and it is what i ran in my G35C, but not in the Z, never again. It was my first mistake I made with this car. redline FTW!!
