    Hello Aubrey,

    I've been using Valvoline VR1 20/50 for many years; seems a popular oil on this forum.

        Any 20W/50 oil with a decent level of ZDDP (1100ppm or better). The ZDDP is supposed to provide better protection for the flat sliding tappets (cam buckets). Most modern oils don't have it as it messes up the catalytic converter. There are however plenty of "classic" oils that fit the bill. VR1 was favoured by a few on here and you used to be able to get it for a good price from Euro Car Parts but they no longer stock it but you can still get it from Opie oils ( https://www.opieoils.co.uk/p-73741-v...ngine-oil.aspx ) - but note that they no longer specify the levels of ZDDP on the european version (different from the American version).

        Classic oils do their own brand oil which has 1300ppm of ZDDP : https://www.classic-oils.net/Classic...Heritage-20W50

        There are many others out there from Miller, Penrite, Morris etc..

        Personally I use whatever 20W/50 with a good level of ZDDP I can get get hold of for a good price at the time. The oil in my car has never got near 3000 miles in a year before I change it so not so worried about long life etc. My view is regular changes are as if not more important than a particular premium brand - but that is all it is .... my view.

              I'm with Roger. Valvoline used to specify their ZDDP levels, but when they changed to packaging and also, I believe, the formulation, they stopped showing this information. Nor is it shown on the Eurpoean version data sheet. I and others, have put questions on this to Valvoline without getting any definitive answer. Therefore once my VR1 stocks are used up, I'll be looking for alternatives declaring their ZDDP. Cheaper price will be an added advantage.

              I had toyed with getting a sample tested, but think it was going to cost £50 - 60 so didn't proceed.

              I have used additive products from Powerenhancer in the past with good results. They advise there are alternatives to ZDDP which are non-hazardous. They advise using their AR900 V2 additive in a mineral oil https://www.powerenhancer.co.uk/arch...-modifier.html to provide the anti-wear properties. This will add £21 to an oil change! The jury is still out

                Not sure if Liqui-Moly is widely available in UK


                Liqui MolyTouring High Tech 20W-50 has a ZDDP content of between 1100 and 1200 according to the manufacturer
                Liqui MolyTouring High Tech 15W-40 has a ZDDP content of 1000 according to the manufacturer

                  I’’ve been using VR1, changed every 3,000 miles. As this means at least 3 changes a year I’’m now on my last gallon so I’m glad to know that the specification doesn’t necessarily include the high ZDDP level anymore.

                  I’’ll be watching this thread for advice on future supplies!

                    ADD TO BASKET
                    Penrite Classic Light is an SAE 20W-60 oil and can be used to replace SAE 30 and 20W-50 grades. It has been previously sold in the UK under the name HPR30.

                    Specifically made for engines manufactured between 1950 and 1975 including most classic cars, particularly high performance vehicles such as MG, Jaguar, Triumph and Porsche. Also good for motorcycles of the same vintage. Also suitable for cars running six volt electric systems and motorcycles, where cranking / kick start speeds require an engine to turn over with minimal drag.

                    This broad spectrum multigrade means that starter motor cranking loads are reduced as compared to a monograde oil, while hot oil pressure is improved.

                      Settle down with a glass of something and read through this. 540 RAT – Tech Facts, NOT Myths

                      I won't give you my opinion, but I certainly look at buying oil and additives differently that's for sure!

                      Read it and you will never need to wonder again!!

                        Yes I have read that blog before - I think you may have posted a link before. Makes an interesting read and section 9 does question the validity of ZDDP levels alone in determining wear protection for flat tappets. His testing, if you believe what he says , does rank oils in terms of effectiveness. The only problem is that all the oils listed are ones available in the U.S. and they are not always the same formulations here in the UK & Europe. I made the comment about VR1 as the Valvoline (Europe) product technical data sheet has been reissued & updated several times in the last couple of years since it became "flavour of the month" on the forum. I did contact Valvoline directly about this seeking reassurance about zinc / additive levels and changes in formulation. They wouldn't confirm or deny any changes and replied with the following simple bland statement: (have included my original email and their response, this was the second email I sent as the first did not get a response)


                        Dear Sir,

                        The quality of the VR1 Racing 20W-50 has stayed the same.
                        It is still safe for your car.

                        Kind regards,

                        Dear Sirs,

                        I have just noticed that the packaging for your VR1 Racing 20W 50 mineral motor oil has changed along with the product code - was VE11591 but is now VAL-873432. I have also noted that the Product Information sheet on your website ref: 025/10c no longer refers to ZDDP, earlier versions did. I run an older classic car with "flat tappets". ZDDP is regarded as an essential additive for minimising wear in this type of engine. VR1 is regarded in classic car circles as a good "safe" oil to use. I have looked for a specification showing the level of ZDDP additive. I believe it used to be around 1200 to 1400 ppm in the older product (VE11591) but can find no specification for the latest version (VAL-873432). Please can you either provide this information to me or tell me where I can find it.

                        Thank you

                        Roger --------------------------

                            IIRC the oil expert positively shunned ZDDP additives.......
