Penrite 15w/60 engine oil woes !
Discussion
I decided to use Penrite engine oil as it was recommended on here,,,,
Total waste of £60 + and oil filter.
Put the stuff in and I have noisy cam followers, tried running it for about 300 miles and it was still making noise so removed the oil, put Castrol Magnatec 10w/40 semi synth and a new filter In and instantly quieter,,,
Thoughts chaps please ?

Not really, oil pressure was generally higher on the gauge at tickover with the Penrite but about the same when raising the revs but didn't seem to use any oil at all.
I had my engine re built by Dom at Powers and he said it would make more noise on the Penrite,, mainly when shutting off and using engine braking I could hear the followers clattering away ( he was right ) as usual !!
Viscosity is the culprit I'm guessing ?

Exactly Carsy,, why did I think otherwise! I've always had a bit of clatter and just liked the idea of the zinc but the 15/60 was not the one for my engine. You live and learn and I should just listen to Dom, he's the expert !
Happily it's quietened down almost from the moment I fired it up after putting the recommended oil back in.

I would always take the advice of a specialist like TVR power over a DIY mechanic on here to be honest. Although as we have seen on Phers forums the specialist isn't the most reliable. I know there are quite afew excellent sports cars service centres out there which TVR owners use to great effect, Although TVR power, str8six cambs and nottingham, X-works service , vtrack road are the main dare l say it dependable service centres? Total waste of £60 + and oil filter.

So would I and normally do but for some stupid reason I thought the Penrite may well be extra protection.
An expensive way to find out Doms the Don all along.
My engines now out of warranty and so I was just trying to look after the thing but I won't be doing that again!
It was my decision after all and the Penrite is probably fine in other engines but it's worth noting it does not work in my 4.6.

When was your engine built then if it's out of warranty? I thought it was around the same time as ours (completed December 2014) but obviously not? An expensive way to find out Doms the Don all along.

2012, before the 5 year warranty came in but now I've put it back on the oil Dom recommends and I'm going over to see him soon enough, this is actually the first oil service I've done as Powers would normally do it so I might talk about an extended warranty which Dom has mentioned before.
Is it a trait of my 885 cam or is there something not quite right as I've had a little cam follower noise ever since it was re built,, someone said its a trait of that cam but I'm not convinced, any clatter to me means out of tolerance and wearing unduly,,, I've just driven the car and it's now very quiet but I can hear at least one follower still complaining when de accelerating at about 1700 -1400 revs,, it's a very slight noise but it's there and always has been,
Other than that the engine is smooth and fast and there's no cam noise at all at higher revs, just that slight rattle as I'm coming down the revs,,, !
It's why I tried the Penrite but that clearly exasperated the situation. It's the same follower or cam area that makes the noise whatever oil it's on!

As far as unwanted noises go (like tapping) are concerned, I have to say mine is quiet as a mouse on Penrite 15w/60 
It actually reduced my engine noise when I first switched to it a few years back, so I'm doubly
A hot 15w/60 will be a lot thinner than a cold 10w/40, so if it makes unwanted tapping noises on hot 15w/60 by rights it would also tap on cold 10w/40
So I'm now totally three times confused
This is all very odd

Yeah, put a straight grade 50 in it; will be perfect for a classic. Make it castor based for maximum effect (and minimum life).
The clue here is in the first number. 15 (or 20) anything is too slow to flow and build pressure from start up on anything with decent tolerances (just because the engine was designed eons ago doesn't mean it was made with Victorian clearances) Putting aside zinc levels, which is another can of worms, I've long since settled on 5w50 as being the perfect multigrade for the RV8 (if a 0w/50 existed, I would use it)... trouble is, it's not so available. 10w/60 is and works, but can be a tad clattery for a moment or two while pressures build.

These statements from the OP seem to be especially relevant here...
I think there is more at play here, and the OP's own two statements above may be giving us a clue

I've been using Penrite 15w/60 for years now with no ill effects or tapping sounds, and I'm not sure who's debating the benefits of zinc as it been a proven anti-wear compound added to engine oil since the 1930'sI think there is more at play here, and the OP's own two statements above may be giving us a clue

Now that's exactly what I've been thinking,, and that's exactly what I experience on 10/40 The clue here is in the first number. 15 (or 20) anything is too slow to flow and build pressure from start up on anything with decent tolerances (just because the engine was designed eons ago doesn't mean it was made with Victorian clearances) Putting aside zinc levels, which is another can of worms, I've long since settled on 5w50 as being the perfect multigrade for the RV8 (if a 0w/50 existed, I would use it)... trouble is, it's not so available. 10w/60 is and works, but can be a tad clattery for a moment or two while pressures build.
The 15/60 and it's the 15 as you point out which seemed to cause my problem. It was hardly knocking like an old Pinto but it clearly Made a consistent clatter at the given revs,,
Dave you sound like you know what your talking about so imagine how this thick pillocks thinking
It doesn't make much sense but it was a bit of a relief to fire it up when back on 10/40 and the noise pretty much disappear immediately,,, the Penrite looked lovely and came back out like new so I'm disappointed but it's just what it is.
Alls well that ends well I say

I've done 13,000 miles on this cam and it's always had the same intermittent follower sound but very rarely is it anything ther than a very slight tapping and Only lasts a second or two, and it's not any louder than it ever was,, it just simply didn't like the Penrite oil at a given revs and gave a constant clatter until it was either higher or below around 1500 revs,, it was silent on Penrite on tickover nd the bottom end seemed very smooth, other than that bleed down when shutting off abruptly I liked the stuff,, I don't get it either Dave but Pupp seems on the money, the 15 caused my engine problems maybe ?
The engine builder told me so before I used the stuff so that's
Anything over idle is going to give you a genuine 50psi of oil pressure.
After that oil pressure is managed by the oil pressure relief valve so will be maintained at a consistent 50psi no matter how fast the engine is spinning,
The only other influencer of pressure being the temperature of the oil, s the oil gets hotter it gets thinner and if the oil gets too thin the hydraulic followers will spill oil at a rate faster than it can be replenished.
At which point the follower may well tap.
The Penrite 15w/60 is heavier than a 10w/40 you were using, so logic dictates it will stay thicker for longer and will actually be less likely to promote a follower related tap.
What the OP is saying is, he put a heavier oil in the tapping became worse, now consider the facts IE... when the Penrite 15w/60 is hot it will be a lot thinner than a cold 10w/40 so the engine would just as easily tap on cold 10w/40 oil.
Well, looking at the OP's previous statements maybe it does... a bit
