I forgot to mention also that he cut the filter open and saw no glitter at all in there. Yep, I'l give him a call shortly. Fingers crossed! -
It's not ideal, by any means, but I think many of the horror stories are because of people not understanding what it is, what it does, what their VSS that they need to modify looks like and whether the Jaycar unit is applicable. In principle, it is relatively easy to build a device to take in an AC variable (peak) voltage variable frequency signal (which is what you get from most Nissan speed senders) and just spit out a constant (peak) voltage variable frequency AC signal at a different (modified) frequency. -
Find out how much lead is in that additive. Lead is normally a no-no, but seeing as it is an "additive" they might be able to get away with relatively low levels in their product, that could then turn up at the ppm level in the bulk oil.

Ok thanks for that info. I’ll have another poke around when I have time and update you guys -
So, I wish I'd done an oil analysis before changing my turbos because my analysis shows elevated (53 ppm) levels of lead. I don't have an analysis before this, so there is no trend. I'll do another change and analysis in 5k to establish a trend but I'm curious about whether this is just a sign of a steady decline? I have no knocks and oil pressure seems ok. Is this something my engine can recover from or is it on borrowed time? My mechanic did add some additive for stem seals in the last oil change which would be in this analysis. I'm not sure if that would affect anything. Also, the oil in this analysis is the first oil change I did with the car so I have no idea how long it had been since the previous one. I was given a service history but I don't fully trust these. I know we don't have heaps of info and I'm kinda freaking out a bit, maybe prematurely.
