You've still got locks garage nearby then? Though until you fix the mpg issue its probabbly pretty pointless anyway.

I've deleted that station now

Yep locks garage is still there.

according to the google!!!

OK, that's an ugly link :(
But that's the Comma oil I use in the Duchess.

Yoink!!! :)

Hmm

Seems the XS 10w40 has more Zinc calcium and Phosphorus than the motorsport stuff..

However being a full synthetic its VI is better..

I still use 20/50 mineral oil, although it’s getting harder to find unless I buy online, synthetic wasn’t around when these engines were designed,, so for now I’ll stick with it..

V8 Developments reckon it's the zinc content that keeps the camshaft in good order so that's what I'm focussing on when choosing oil for our new engine.

Zinc is very important for old flat tappet engines from everything I've read. If a genuine lubrication engineer wants to step in I'd love to hear more.
Yes, the Comma 5w50 is lower in Zinc than some other grades at 900ppm vs 1200ppm which is the highest I've found so far. But I went with the higher viscosity and compromised a bit on the Zinc, because it's still much higher in Zinc than oils designed to the latest manufacturer specs (which don't seem to have any at all).

Who's right? Who can tell?!! See you in 50,000 miles :D
(I hope!)

Been a while ... time for oil again!
My use has been very irregular in the last times, and I made the mistake (!) of having the P38 out of commission a couple of years with the old oil in. Thus when I had the last oil change (270K km) it did not come out nice, was very darkish and with several "blobs" or "clots" ... which I assumed it was gunk on it for the years it stayed there. Ugh ....
I put then the Comma X-Flow 10W-40 and promised me to replace it at no more than 5K km, to try to clean it up a little.
As expected, I am now hitting 280K km and had not touched it :-(

What would you guys suggest? Go again for a lesser oil and this time go for a earlier replacement, or bite the bullet and go for a proper thing? I am tempted to go for a higher grade (50 or 60), as hotter temps are coming into play and I use the beast mostly for longer, higher speed trips, and obviously the towing.
But besides the readily available 10W-60 or 15W-50, I was looking at something like the "Motul Classic" which claims it has among the highest quantity of ZDDP additive, which I gather is a welcome plus for our venerable powerplants ....
The Motul Classic on 15W-50 does not seem to hold the same viscosity at higher temps like the 8100 10W-60 for example, but the ZDDP additive should be a valuable contribution. I am wondering if a 15W isn't too much for winter, though, which here is not so bad as years ago, but cold nevertheless ...

A friend has also suggested I try a product called Pro-Tec Nano Engine Protect ... which I might try, shouldn't hurt!

Ideas? Suggestions?

I think this is the same product. The VW site calls it snake oil. Personally I wouldn’t use it.

V8 Developments told me to use a 10w40 oil that has Zinc in it to prolong the life of the camshaft. I’m sure it was Valvolene they recommended.

I have just had my engine completely rebuilt by V8 Developments. I've now done 1,000 miles & the dipstick indicates that I will need to top up soon. Just yesterday I exchanged emails with V8 Developments inquiring about oil & they told me to do an oil change now followed by an oil & filter change every 5,000 miles subsequently. The oil they recommend is Valvoline VR1 Racing 20w-50.

Well, I solved the riddle .... passed by one of my "dealers" today to talk about, and I came home with 6lt of Mobil 1 5W-50 for 64 euro ... will see how it goes with this one :-)

@Harv, no I do not think is the same thing, I do remember the "magic of the nano rebuilder potion" from some years ago and dismiss it as you did.
This is just a anti-friction anti-wear additive. It costs a few euro, so I guess does not hurt to try it ...

You’re right, it’s a different product. I’d still be leery. If you use it, let us know how it goes.
