Mark,
Thanks, that was interesting reading. I assume you've got a GU 4.2; not a GQ? The GQ I owned used 2 Z115s, but the GU is the one which has the Z416 and Z503.
I might try the oil you're using too; see what happens. As a rule I've got a "thing" against Castrol though, so my mind will be set against it from the start.
Cheers
Roachie

Interesting reading, I noticed on the Penrite web site that they recommend using HPR lite oil 15/40w. My question, why use 20/60w ???

Being in Cairns I classed myself as living in a warm to hot climate and the manual recommended either 20W 40 or 20W 50. I couldn't actually find the 15W 40 Penrite anyway but if I did would have stuck to what I was already using (RX super).
Anyway, I figured 20W 60 would better suit the supposed requirements than 15W 40 for where I live. I was wrong but overheating only occurred in extreme circumstances so I doubt any damage occurred during the time I used it.
Cheers, Mark.

Mark - ? - You used the wrong grade of oil for the vehicle - it ran hotter - and then you blamed the manufacturer who reccomends a MUCH lighter grade of oil for that vehicle in the 1st place???

You've thrown the proverbial baby out with the bath water here.

Penrite is rapidly gaining excellent recognition for its lubricants globally - thats not open to debate or opinion - its actually a documented fact.

I didn't mean to blame the manufacturer for having a bad oil, I also think Penrite are good, that's why I tried them. I was merely trying to show how selecting a heavier oil can be all there is to having your engine run hot and not some of the more in depth mechanical things that people often look at first rather than last.
I have no doubt that using the 15W 40 Penrite oil would have given me no problems whatsoever, same as Castrol. I did the change as I thought in my climate 15 W 40 was too light but as I said, I was wrong.
Cheers, Mark.

I'll just chuck one more thing in here. According to my manual, running 15W 40 is borderline, hence the decision to try a change.

I know what you mean, I used to like to try the limits on oils, especially on older motors or when driving up north in summer (ex truckie) - going up a grade etc, but honestly unless the donk is using oil I stick to the recomendation. Penrite has a great safety margin at higher temperatures.

Im also a great supporter of any Australion owned and operated companies especially when their product is so much better.
Penrite is Australian.
Cheers

Yeah mate that's the other reason why I tried Penrite, the Aussie connection. I'm all for that too. Next time I'm in the shop I'll see if I can find the 15W 40 version.
I gotta say I'm a bit surprised it wasn't there?
Cheers, Mark.
