Cheers

or sonic 20/50 in the yellow plastic can this oil has 1500ppm of ZDDP added
youtube ZDDP to get up to speed jambo

or champion N9YC plugs

ask at your locall shammy leather motorfactors, you could save a packet on postage

Yeah we run Comma Sonic in the van cos we're too tight to pay for CTV.

cheers, i like the fast reply's

i have BP7ES in stock would they be ok ? also have a couple cans of valvolione 20W-5O VR1 would that be ok ? i have this as i have a couple of old minis but never played with turbo's before !

many thanks chaps

I'd use BPR7ES as I think the plain old BP's can muller the amplifier module.

Also I believe some people on here swear by the Valoline VR1 so go for it!

I doubt very much that Comma oil has adequate ZDDP content for the A series since it has an API SL rating.

You need to be looking for either a specific 'aftermarket' oil like the Millers, Penrite, Or valvoline brands without the API specification, but the right levels of ZDP, or an API SF or lower specification, and to date, I only found one, which is the Duckhams Q

2000ppm apparently colin

Yes, I saw that,but I am not convinced its still enough

Since the specification API SF is obsolite, what does this say about API SL which is for 2004 or later. Why is the SF specification 'obsolite' and SH or SJ too, if the SL is suitable?

Also consider why there is a different specification. Which parts of the make up of the finished product are different to justify a different specification.

Like I said, Duckhams Q is an SF specification for vehicles up to 1988. From this point onwards the ZDDP levels dropped sharply since the introduction of unleaded fuels, cat converters and lambda sensors, which is probibly why the SF and earlier specifications are 'obsolite'. From this point onwards oils were never really as good as they should be for the Mini engine with reduced heavy metals of the ZDDP. I mean, why should oil manufacturers keep the ZDDP levels up in their mainstream products just because the Mini and metro is the only cars still in production with an in sump transmission and flat tappet cam followers? Environmental focus was the main aim for reduction of heavy metals in both the oil and the fuel.

Take that a little further and consider that manufactures consider 10 years the end life of a vehicle, so any vehicles in mainstreme production in 1988 would't see much effect with the reduction of ZDDP in oils over the next 10 years, and since 99% of all cars manufactured were overhead cam separate transmission engined, there was no real need to keep the ZDDP levels high, and those that did need it, would only really start to suffer near the end of life, which wouldn't matter anyway. which is where we are all at

There might be 2000ppm, in the SL specification, but what was it in the SF specification?

The 2000ppm in the Coma 20W50 might infact be higher than would normally be the case since the only engines to use 20W50 ate in sump clutch and transmission engines of motorcycles and Minis, with few others not really worth mentioning

What I suppose I am trying to say in a long winded way, is, there may be 2000ppm in this oil, but what is the actual ppm that should be in the oil that was deemed to be the minimum for flat tappet and insump transmissions? and its not 2000ppm

If you are happy to use cheep shit oil in a £4K+ Insanely stressed engine and gearbox, then im ok with that, but for me, I use the best I can, to give them help to survive longer. Same can be said for fuel.

The way I see it with the low mileage is ctv is only about £40 per year?

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

Aye, true

cheers

you don't see Duckhams about much these days ?

jambo

You can use other oils and add ZDDP to them. Price for the additive is around £10 to treat a gallon and bring it to SF levels of ZDDP. http://www.zddplus.com/

Good FAQ section...

Unipart 20w50 is rated at API SF/CC according the the label on the can - which means engines built to a 1961 spec up to '88.
Marketed as suitable for older petrol & diesel engines, available from all Unipart outlets.

Metric is for people who can't do fractions.

this is mine . so 10,000 ppm to 25,000 ppm ? seems a tad high !

Diesel oils have a far higher ZDDP content as you have found, but for one reason. The higher levels of detergents tend to counteract the ZDDP, hence why they put more in to achieve the desired protection. well thats what I read.

Its the higher levels of detergents in diesel oils that worries me.

Motorbike oils look like a good bet
