Google ULX110 oil
That might help
Its not an additive but an oil with a good concentration of zinc.
You have to get it right as too much can have just as bad an effect as too little?
Any one else using a ZDDP additive in there oil. i have alreadt spoken to the penrite engineer about the choice of oil for my aplication and the recommendation is to use the HPR 30, i have run this oil for years without issues, when i stripped the old engine that come in the car it had major failure of the cam followers, these were CB light weight lifters running on a engle FK 87 cam, i do not want a repeat of this problem.
Thanks.

CASTROL GAVE Me these specs for GTX Zinc 850ppm P 750ppm
and Magnatic Zinc 850ppm and Phosp 800 ppm
anyone know what percentage these are??
I also notice that Penrite classic has the old classification of SG/CD
so, maybe any oil with that classification should do the job
that is if any are still available..? I also notice they say to change the oil at every 3000miles or 5000klms..

Thanks for that, thats what i wanted to hear, some one who has actually used a aditive, Lee, you need to look at oil that has a higher zddp content, 850PPM is a bit low, the penrite oil range has a content between 1200PPM and 1600PPM. gracey how much do you use and the quantity of oil in your engine. thanks.

thats shit, you need at least 1300 ppm (a safe margin) or more for flat tappet old technology engines Lee.
Try Job Gibs DT50 aircooled oil, should be hitting Aussie stockists soon. Its the most highly developed with the most R & D of any vw/porsche air cooled oil in existence as I understand.
BP oil (Brad Penn) is another good one.
Penrite is ok for older engine design with 1100 ppm for the standard synthetic HPR range of oils, their classic/vintage oil probably have more.
ACE 30 has 1000? ppm but formulated with higher anti oxidizer additives to reduce break down from oxidation of the other oil additives from higher temps.
end of the day a person makes his/hers own decision to which oil they use. 😁

Penrite GAS Premium has 0.129% Zinc. I think this is about 1290PPM. I have always use Penrite GAS for my LPG Holden, my motorbike, the Beetle and the Kombi.

I add 1 bottle of zddp to 5L of Castrol Edge 25w-50.
My motor only takes a bit over 2.5L as I run a Pobjoy anti surge sump and no external oil cooler.

I haven't seen anyone recommend using a synthetic oil for a VW engine which still needs to be changed at 3000miles or 5000klms
unless its modified... with proper crankcase ventilation etc..
even Penrite say still change the oil at 3000 miles 5000 klms in VW engines with their classic car oils..

The Kombi now gets HPR10 for the Subaru engine.
Sounds good Pete

Yeah Penrite is probably the best off the self available everywhere oil, but for much better specialized oil like Brad Penn, Joe Gibs, ACE 30 etc... are required.

Hi
I have just ordered some ZDDP MAXX from the USA
interesting reading as they say NOT to over do it..
to balance it out... still trying to sort out how much I'll need... in 5 litres of GTX oil..

You will have to be carefull as to much zinc is just is bad as not enough, i have worked out for my application that half a bottle of additive to six liters penrite HPR30 is about right, the oil has 1217PPM of zinc already and i feel a full bottle would be to much, i have tried to find out from the manufacturer's of the additives what PPM you would have if you put a full bottle of there additive into five liters of oil with no zinc and to date no one has given me a answer, the oil you use already is low on zinc so more that half the bottle might be advisable.
Lucas do a straight 30 with zinc I think they sell it as a flat tappet break in oil for v8's it might be worth a look.as for my beast I've been using Ace 30 no complaints,as for penrite I know a guy who went from Ace30 to the penrite and for no extra chage he got another 25 degrees oil temp👎

Yes, they say that too much is just as bad as not enough and give ppm figures to work on.
Castrol GTX has 850ppm so they told Me about a few months ago..
the person who wrote the info on ZDDP Maxx on ebay can't spell and the details are a bit confusing... along with no actual details of how big the bottles are???
I'm presuming they are 2 US ounces.. which sounds very small
anyway will see when they arrive..

I find the oil temp increase a little hard to follow as ace oil is nothing special, even the zinc content is below what is recommended for a flat tappet cam engine, if that is the issue i will get a oil temp in my car of 75 degrees if i change to ace oil ,thats funny, i will have to remove the oil cooler.

I didn't post about the oil temp increase for anyother reason than to put it out there as I thought it may be of some intrest to some.The lucas oil I mentioned that for the same reason.I'm happy to try and add to the discussions here that may help people build a reliable shit hot VW streeter that dosent cost the earth,which I assume you may be intrested in?You driving your bug to warrick?
I have read a couple of oil tests and the most difference i have seen in a controlled test was about three degrees, as i stated i find this difference unbelievable. both the oils are a mineral oil and would have similar ability to transfere the heat. there would be some other issue causing the temp increase to that degree, as i currently run penrite in all of our cars and have tried many different oils over the years, i have never had any thing like the temp increase of 25 degrees happen to me, i would be a warwick the only problem is i am working over seas offshore at the moment.
after reading this thread it got me thinking about the oil I am using so I did some research into a few brands of oil to see what their zddp (zinc) content was
I currently use Castrol Edge Sport 25W-50
Castrol Edge Sport 25W-50 - mineral oil (not synthetic) - $50 5L (supercheap)
*SEE MY OTHER POST LATER IN THREAD***
All Brad Penn oils (weight of oil doesn't matter) - 20W-50 $127 + delivery (12x 1 quart bottles)
zinc: 0.15% (1500ppm)
phos: 0.14%
🤘Royal Purple - at $95 for 5L on special at supercheap I didn't bother
ACE30 - QP Lubes website is under construction so I couldn't find the info from the horses mouth
I know that the historic formula vee crowd is running the brad penn oil in their engines; in terms of cost the Penn oil isn't that much more expensive because if your using the other oils and then an additive it wouldn't come out that much cheaper IMHO
What am I going to do now? Probably buy a case of Brad Penn in 15W40 or 20W50; but with that said I'm still happy using the oil I've got and would also happily use Penrite HPR30 as I used to before I had the motor rebuilt
With all the above said a Castrol Tech had written a piece about zinc in oil etc and he commented that for the anti-wear properties of the zinc to be properly activated the oil needed to reach a temp of at least 80 degrees Celsius so no matter what if your engine is running too cool it will wear quicker
I have a print out from the penrite site and the HPR 30 is listed with a zinc content of 1217PPM, the highest in the penrite range is the running in oil at 1600PPM.

here is one I just got off the website again; using the website not google - Sept 2012 up to date the zinc content is actually less than the other data sheet
Ive been using Penrite in the bus and ACE30 in the bug. Not really sure which i like the best yet. I haven't been using ACE for that long as i always used Penrite 30 non syn before i was put onto ACE. I'd be ineterested in trying that DT150

I've had customers comment on the improved engine quietness and oil life when they have switched from Penrite to ACE, similarly Castrol to ACE. I've been using ACE for around 5 years now, even pulled down a few engines that have been on it, one of which exclusively used ACE and bearing, cam and lifter condition has been superb. I don't like Penrite as I believe it to be excessively thick for it's rated viscosity which IMO impedes piston and bearing cooling.
