HSM Posted April 6, 2017 Report Share Posted April 6, 2017 Valvoline VR1 Racing 20w50 ZDDP content 1448 ppm. ( about £30 per 5 litre ), would recommend frequent oil changes to maintain performance. Harvey S.Maitland Quote Link to post Share on other sites
stillp Posted April 6, 2017 Report Share Posted April 6, 2017 Reply today from Halfords, stating that "the attached Safety Data Sheet which holds all the information regarding the product". However it only gives the zinc content as <1%, so not much help. I pointed out that the SDS didn't answer my question, their reply was that that was all they know! Now to try Comma Oils.

Pete Pete I think the Halfords Classic is produced by Comma, (comma 20/50 classic) same oil same price. Paul Quote Link to post Share on other sites
stillp Posted April 6, 2017 Report Share Posted April 6, 2017 I think so too Paul. The SDS confirms that the Halfords oil is manufactured by Comma, but doesn't state whether their oil is identical. Pete Quote Link to post Share on other sites
MostEasterlySteve Posted April 6, 2017 Report Share Posted April 6, 2017 The Halfords stuff is made by Comma, who also make the same stuff for Wilkinsons (which always charges £15 and the tin is the nicest of the three!). Zinc content is 0.7pc (700ppm). As an earlier post stated there was a thread a while back and it was mysteriously completely removed...does anyone know why? I didn't imagine there would be intrusive censorship on this forum but apparently I was wrong but I can't imagine what was said in the thread that could have caused its removal. Morris Golden Film is 700ppm. Castrol Classic is approx 800ppm (recently uprated to API SF from SE). The Comma/Halfords/Wilkos stuff is API SE, as is Carlube Classic 20W/50. Duckhams Q had been API SF for years before its withdrawal. Given that you can pay the same or only slightly more for higher spec oils with higher zinc content I don't know why anyone would use the Halfords stuff. Quote Link to post Share on other sites
oldtuckunder Posted April 6, 2017 Report Share Posted April 6, 2017 t I don't know why anyone would use the Halfords stuff. Lawnmower doesn't mind it mind you its grateful for any attention! Got some old 98 octane fuel last weekend and marmalised the mole hills! Alan Quote Link to post Share on other sites
peejay4A Posted April 7, 2017 Report Share Posted April 7, 2017 £15 for 5 litres of Comma vs >£30 for Valvoline is hardly slightly more. Quote Link to post Share on other sites
iain Posted April 7, 2017 Report Share Posted April 7, 2017 This debate always intrigues me. The engine components which need ZDDP are hard to get at when you have made a mess of them... the time and trouble/labour and parts charges to repair will be significant, so why skimp on your oil? Am I missing something? Iain Quote Link to post Share on other sites
RogerH Posted April 7, 2017 Report Share Posted April 7, 2017 Hi Folks, back in the 50's & 60's what did TRiumph recommend for the engines and what was the ZDDP level then. This discussion about ZDDP is very good but how relevant compared to what was the original standard.? Roger Quote Link to post Share on other sites
iain Posted April 7, 2017 Report Share Posted April 7, 2017 (edited) Hi Roger I was thinking the same when I wrote the above.... Summer Grades were as follows from the Workshop manual Tr2/3 Shell X-100 30 Essolube 30 Duckhams NOL "Thirty" Mobiloil A Castrol XL Energol SAE 30 So there's a research project for someone Iain Edited April 7, 2017 by iain Quote Link to post Share on other sites
Motorsport Mickey Posted April 7, 2017 Report Share Posted April 7, 2017 Well to balance every bodies views and "square the circle" why not use Classic Heritage 20w50 mineral oil which has ZDDP at 1300 ppm and only costs £15.50 plus VAT... There the costs are the same as Halfords whilst the ZDDP are up where recommended plus it's not a synthetic and so unlikely to help your bores to glaze, and I don't have to research 5 different oils no longer available to find ZDDP content which may not be even mentioned. Can we now get on and moan about the International weekend costs...that's what we do. Mick Richards Quote Link to post Share on other sites

That's a bit like going to the Doctors today with something serious, and he says yes we can treat that easily with today's drugs, but according to my 1960's medical reference its usually fatal and the only thing I can do is give you some pain killers. Things advance and improve, and for those of you who believe that because something was the best in 1960 it still must be, will you please take the discussion off line and continue via post and the letter pages of TR Action Alan Quote Link to post Share on other sites

Peter Cobbold Posted April 7, 2017 Report Share Posted April 7, 2017 ZDDP goes back decades - its 1940s technology - and has not been bettered by modern antiscuff agents. Its demise is not because a better antiscuff has been discovered, it's because it kills catalytic convertors. Diesel oils still use ZDDP. Peter Quote Link to post Share on other sites
Waldi Posted April 7, 2017 Report Share Posted April 7, 2017 I looked at a datasheet from Valvoline VR1Racing 20W50, and it claimed a zink/phosphor content, but no ZDDP level? It was only valid for USA/Canada. Some otther suppliers list the Zn level in the data sheet but not the ZDDP level ( which then should be higher I guess). Other fora discuss Zn-levels in oil, not ZDDP. Confusing. If it is so important, why is it not clearly indicated on rhe datasheet? Waldi Quote Link to post Share on other sites

Waldi Because we suspect that firms aren't too happy that you find out that their oil is formulated with low ZDDP and therefore won't use it, or it at least reduces their sales because owners have to "self medicate" with ZDDP additive to get the protection required. Half of the firms won't have given any consideration to specially formulate to suit older cars, especially if costs them a cent more. They just like to jump on bandwagons and pick up the cash, so they don't make it easy to find out info. Micky Quote Link to post Share on other sites
