I have a diesel Fabia, my brother has a petrol Micra and my Mum has a petrol 406. The Castrol website recommends 5W-30 or 10W-40 for the Fabia, 0W-30 or 10W-40 for the Micra and 0W-30 or 10W-40 for the 406. I bought 20l of semi synthetic Chevron Supreme Diesel 10W-40 from Costco for £35. Can we use it in all our cars?

No. Just don't do it. Google as to why.

That oil will be fine for those cars, as long as the oil change intervals don't exceed 10 to 12k.

It's a Fabia SDI so it's not a PD engine.

Not really. Diesel engines run much higher compression ratios than petrol engines and they run a lot hotter, so the oil is formulated to deal with this. Plus they produce a lot more dirt in terms of combustion by-products. Diesel-rated oils typically have more detergents in them to deal with this. It's not unheard of for diesel oils to clean a petrol engine so well that it loses compression. Diesel-rated oils also have an anti-foaming agent in them which is unique to diesel engines, and not needed in petrol engines.

See what specs the cars require, SL etc. for petrols - can't remember what the diesel ones are.

If the oil meets or exceeds the specs the cars need, then yes you can use them. I'd be most concerned about the Fabia needing a certain spec.

It's 5W-40 to 20W-50 according to my Haynes manual. It's on the standard service interval based on distance and time so doesn't require Skoda 503 00.

So I guess the Chevron Supreme Diesel 10W-40 is fine for the Fabia but not for our other cars?

The oil in your link is rated SL/CF, SL is a good spec for petrol engines and CF is a good spec for diesels, so it quite a good oil suitable for both petrol and diesels.

They're the viscosities - you need the API specs. They should be in the owner's manuals.

Yes, these modern very low viscosity oils are only required on long service intervals, to stop the oil turning into glue and to give slightly better economy.
You're best using a decent 10/40 oil and changing it more often.

Yep, there'll be a 200 litre drum of 10/40 in a corner of most garages.

You could probably use it and it would probably work, but don't you think if manufacturers specify a particular type of oil it might be for a reason?

Chances are the wrong type will accelerate engine wear or do some kind of damage.

Why take the risk?

ETA: There's a reason there's a million page Opie Oils thread on here!

The Castrol website is wrong and always over specifies the oil for the car. Look up a '99 Renault Clio 1.4 which the manufacturer specs 15W40 mineral for and see what Castrol say!

In short you can't use that oil really, but if you drop it out every 6k miles and the cars aren't that valuable then you're probably OK. I'd still use the proper stuff.

In my opinion you'll be absolutely fine with using the oil you've got in all of your cars.

Certain engines do need different oils really (VAG PD's, Ford Zetec's etc) but your average few year old shopping/commuter car it really makes no odds IMO so long as it's roughly the right grade. As said, most garages will be using the same oil for anything they service anyway, and my attitude is that fresh oil is always going to be better than oil that's been in there for 10k miles or whatever (things like running-in oil excluded, of course).

The 156 and the Golf both use 10/40 which makes life easier.

i think people need to be more specific than 'no google it', that gives the impression you know something important we don't. I found this topic whilst googling this chevron oil. I am about to use it in a large cummins diesel engine which requires an API CD oil as it's turbo charged. This well priced oil is CF, so well above a CD rating. It is good for big engines as well as small ones and is sold by some people as a substitute to shell rimula x 15w-40, which is much more expensive.

so if you know something for a fact which we don't, please tell
