0W is by far the best for stopping cold start wear and cutting cold engine fuel consumption.

Preferable for anyone currently using 5W30 with noticeable extra smoothness on those colder mornings.

Not a particularly great fuel economy oil. Nobbled by the fact that it's A3/B3/B4.

Can still get this in Lidl for half the price. 15W40 is good down to -25C so ok for cold starts.

Can I use on my Astra MK4 1.6 2003? Usually I buy 10W / 40 ACEA A3 and my Haynes suggests 5W / 40, 10W / 40 or 15W / 40 to ACEA A3 or higher.

I would not use a 15W oil in a modern engine myself. ( Most would recommend a 5W nowadays for better cold protection or 10W minimum)

IMO, I would only use 0W oil if i knew that it was a very modern engine with no oil leaks and it does'nt burn oil, or your may lose more.

You can, but its a little thin. Ideal for complex engines which the GM unit in your astra is not.

Not sure if i am with you on this.
A3 = High performance and/or extended drain.
B3 = High performance and or extended drain.
B4 = Suitable for direct inject engines.

How are these in anyway bad? This is great oil at a hot price and ideal for anyone running a half decent car e.g VAG group. Older engines / less sophisticated engines spec higher viscosity oils because they are not engineered particularly well (i have seen GM piston rings you could drive a bus through). The last thing you want is very thin oil seeping its way around places it should'nt.

If in doubt (or you don't know what you are talking about) stick to the OEM spec.

P.S That Lidl oil is nasty ass gunk that i would not even put in a lawnmower. Oil is CHEAP, parts are NOT.

I spent all my working life in the oil industry & spent the last half designing engine oils for a living. So yes, I do know how to do the comparison.
Just because something is cheap doesn't means it isn't fit for purpose. I long ago came to the conclusion that most top tier synthetic oils are massively over-specified relative to the function that they are required to carry out (which usually entails 10,000 miles of moderate driving).
15W40, outside of the US, is still probably the commonest grade of oil sold today and is quite happy being pumped around even the most modern engine.

The ACEA A3, B3 & B4 oil specifications require you to meet a 3.5 minimum HTHS viscosity spec. This puts a limit on how thin the oil can be at 100C. As a consequence, such oils aren't fantastic on fuel economy (hence my comment). If they were ACEA A1/B1 oils, they would be much better on fuel economy.

The Lidl oil is A3/B3/B4. I checked. Hardly 'bad ass gunk'!

And trusting OEM specs? If only you had seen what I have seen, you would not say that with such authority!

joe90, in a full oil change using 4L, would this give you any for topping up?

if not, defeats the purpose to top up with "cheaper" oil

Depends. My car has a full oil charge volume of 3.2 litres so in my case, yes, 4 litres would give my some to top up with. If you have a bigger engine, then probably no.
A 15W40 tends to be less volatile than a lighter oil (0Wxx, 5Wxx, 10Wxx) so under normal circumstances you should not need to top it up so much.

I would say it because i would not want to invalidate my warranty, nor disagree with the manufactuer of the car on the say so of some one who has spent there entire working life (your not 16 by any chance?) on an internet forum. You obviously know a little something but just out of intrest what would your advice be - to ignore the OEM spec?, or as i said follow it.

Castrol are buggers for there 4l cans. Dependant on engine size, my old bmw 640 had an 8 litre sump -.- The most expensive thing about servicing it was often the oil!

Strange, using 5W30 I never ever needed to top up,
Its the first 5W part that specifies how thick it is at cold.
the 30 refers to how thick it is hot.

So it is 0W30, 5W30, 10W 40, 15W 40 and 20W40 in that order for cold start wear from low to high.

A car manufacturer willl recommend what their oil sponsor wants.
It's why Mobil 1 got negative press, spnsors saw to that.

Obviously any car that uses xW/40 cannot use xW/30.

LadyEleanor

Obviously any car that uses x/40 cannot use x/30.



It's not obvious to me. The engine doesn't know and doesn't really care what oil it's circulating. Wear is so controlled these days by additives, that it's not really a issue anymore. I use a 0W20 is my car and there are no wear metals in the used oil to speak of.

This is only classed as synthetic as it has some in it (they won a court case in the USA), go for a real synthetic oil for this price...

Your thinking of magnatec, Edge is fully synthetic.

Fully synthetic and quality like this usually means oil changes can be doubled.

Read up on it.

0w20 would mean the engine is incredibly engineered.

xw40 means it needs thicker oil to because the engineering is less sophisticated. Using a thinner xw30 there would be a small possibility of metal on metal as the engine turns.

Formulated and blended the 0W20 myself from scratch as a fuel economy oil. The oil carries no formal specs but I get it for free and it gives me 60 mpg so I'm happy.
Engine is by Daihatsu and the oil is my own personal take on Daihatsu's 0W20 factory fill oil. It's typical Japanese engineering but nothing fancy.
Ran the oil out to 15,000 miles (way above the recommended 9000 oil drain!) and it was fine; no oxidation, no wear metals, just a bit of fuel dilution but that's par for the course.
Oil is like blood. The thinner it is, the less energy you need to pump it around your body. Also less system pressure means less likelihood you'll develop a leak!
However, if I had to pay for my oil, I'd go for the Lidl 15W40 everytime.

price is £37.99 now. Hot vote for the previous price
