Shell Helix HX7 oil specs

[Darkcat]

I'm trying to figure out the ZDDP content of Shell Helix HX7 10w40 oil, but cant find a spec sheet anywhere that details its vitals...

Can anyone point me towards a spec sheet that does??

[Garett]

Is it available on the opie oils website? They usually have the tech info on there.

[mmm-five]

The OpieOils tech sheet (which is just a copy of Shell's tech sheet doesn't mention it.

However the MSDS (safety data sheet) also doesn't list it, which usually means that ingredient in not in that formulation.

The Ultra range has ZDDP listed though - at 0.1 to 1.5% concentrations.

No, they only link to the same one i can get from shell themselves:

No real tech data on it...

Interesting... thats a VERY wide range, its not recommended to run any more than about 2000ppm (0.2%) otherwise it can eat away your cam lobes VERY quickly, at 1.5% that's 15000ppm!!!!!

Hmmmm, seems even Shell don't know whats in it...

Luckily I'm only using it as a flushing oil for a few hundred miles, i'll throw some ZDDPlus in to be sure.

Its a API SM

means its a lower zinc ZPPD oil

SL is high zinc, SM onwards they slashed it

API SL is what your looking for.

That's only a stated maximum permissible, chances are they'll use significantly less than that.

I thought zddp was there to prevent wear?

[cirian75]

Yup

API SL spec is the last of the high zddp oils, API SM spec onwards it dropped radically to low zddp


also

A1 is fuel economy oil and not as good at protection unless the engine was designed to use it

A5 is 50/50 economy vs protection

A3 is the highest protection

so API SL A3 is the best spec for protection.

API SL A5 is nice balance

I'd never touch a A1

It is, BUT too much can have a VERY negative effect.
Its like we all need salt to live. but too much will kill you.

Manufacturers rarely give out the ZDDP contents of oils (some American ones do, but ZDDP is the be all and end all as far as many Americans are concerned).

Yes, the ZDDP content is reduced in SM spec oils, but what car is it in? Does it need a high ZDDP level? High ZDDP isn't always a good idea.

Hi Tim
Its a Ferrari Mondial QV.

Ordered some gearbox oil for it from Opie yesterday evening actually :-)

[opieoilman]

Hi

Thanks for the order.

With the Mondial, it doesn't need a reduced ZDDP oil, so an SL would be the standard choice, but going for the right SM oil will be okay as well. Although SM has a reduced ZDDP content, it is reduced not removed and even a reduced level will give protection.

Cheers

I've bought quite a lot of oil etc from Opie over the years but they aren't that competitive on price these days and they dont honour their price match claim. Despite their excuses not every one that's cheaper is selling old stock or trading from their garden shed.

OK thats fair, whats your opinion on ZDDPlus additive?
As a flushing oil i was going to throw in the Shell HX7 with some of that to be sure (which i have both of ) and run for a few hundred miles to flush the system before buying some decent oil for it.

Well not everyone can be competitive on everything can they? The gearbox oil i ordered was VERY well priced, plus a 15% discount offer, AND excellent advice - a certainly cant complain at all.

No but why advertise a price match and not honour it ?. I'm buying synthetic oils etc for 3 cars and a bike every year, Id prefer to have it delivered in one parcel but not if it costs 50% more.

I see what you mean but life's not that easy.....

If you have tried selling online (NOT through amazon/ebay), you'd understand.

What's wrong with buying through ebay ?.
