bought from watford yesterday but believed (told) nationwide, looking at the codes on container this is a good spec oil. very good price for a fully synthetic oil.

from wikipedia
The first real synthetic engine oils appeared for aircraft engines in World War II concurrently in Germany and in the United States. The motivation in Germany may be primarily related to resource issues, but also to functional performance requirements. The base oils for aircraft engines in Germany were based on a blend of an adipic acid ester with a poly(ethylene) oil[5] e.g. polymerized olefins/ethylene. Easing engine starts in winter and avoiding soot deposits in the oil radiator were two of the drivers for the U.S. Air Force,[6][7] to adopt polyglycols (polypropylene glycol monobutylether) starting in March 1944.

Advantages

The technical advantages of synthetic motor oils include
Measurably better low and high temperature viscosity performance
Better chemical & shear stability
Decreased evaporative loss
Resistance to oxidation, thermal breakdown and oil sludge problems
Extended drain intervals with the environmental benefit of less oil waste.
Improved fuel economy in certain engine configurations.
Better lubrication on cold starts
Longer engine life

]Disadvantages

The disadvantages of synthetic motor oils include

The lower friction may make them unsuitable for break-in (i.e. the initial run-in period of the vehicle) where friction is desirable to cause wear. Improved engine part machining has made break-in less critical than it once was, though. Many modern cars now come with synthetic oil as a factory fill.
Potential decomposition problems in certain chemical environments (industrial use dominantly)
Potential stress cracking of plastic components like POM (polyoxymethylene) in the presence of PAOs (polyalphaolefins).
Synthetics do not hold lead in suspension as well as mineral oil, thus caution is advised when the engine is run on leaded fuel.[citation needed] As an example, leaded fuel is still commonly used in aviation (avgas).[18]
In July 1996, Consumer Reports published the results of a two year motor oil test involving a fleet of 75 New York taxi cabs and found no noticeable advantage of synthetic oil over regular mineral oil.[19] In their article, they noted that "Big-city cabs don't see many cold start-ups or long periods of high speed driving in extreme heat. But our test results relate to the most common type of severe service stop-and-go city driving." According to their study, synthetic oil is "worth considering for extreme driving conditions: high ambient temperatures and high engine load, or very cold temperatures."

this is in the gold container, they also have semi synthetic for the same price
Synthetic oils are not recommended in automotive rotary engines.[

It's very good you put positives as well a negatives in there. ;) Heat
#2
it gets better

just looked on the container and it say this is a low SAPS oil, low ash oil which generally cost more, although its written in the small print on the back instead of making more of it beats me!

anyone know who makes the ASDA oils?

It’s very difficult to judge the quality of engine oil. Some oil manufacturers know this and take advantage of it. They make various claims impling that their premium price oils are vastly superior to anything that costs less. Armchair experts simply accept this and repeat the mantra - “it’s false economy to use anything other than expensive oil”
The truth however is more complicated than this. Top price oils may be superior but this superiority may be of no real benefit to most cars. For example the ability of an oil to work well at extreme temperatures is impressive, until you realise that most engines will never operate at temperatures even approaching these extremes.
The problem with supermarket oil is different, it may be cheap but is it good enough? For some years Halfords have simply rebranded Millers oils and I know of no one that has had trouble it. If Asda is doing the same but at a more competitive price then this might be a good deal. If however, Asda is selling oil made by an inexperienced company working to a low standard then this might be a false economy.

this is great for starting in cold weather, i have started a merc at minus 30c no probs with synthetic oil in the sump,

Old worn engines won't like it as it is so thin it can get above the oil rings and could take out the cat in the exhaust
#6
from memory (its down in the shed) its SL/CF ACEA B3 B4
#7
It looks good for the price, has it got any VW numbers ? eg 505.01 or 507.00 cheers - Stuart.
#8
Just bought a couple from Stevenage. No VW numbers though, just what veralum said.
#9
Great price. Hot!!

can someone explain what the 5w40 means?

i need it for a clio 03 plate!

cheers

#12
look in your hand book it will say which oil your car takes, first number 5w means how thick oil is when cold, lower is better, second number is how thick when hot.

You won't need fully synthetic oil for that car mate.

good deal!

Thios offer may also extend to branded products as I saw this posted on an MX-5 forum a few datys ago:

Was back there (huge ASDA in Swindon) today and took note of what's on offer:
All Mobil, all 5 litres
1 - 0W40 synthetic - £16
1 - 5W30 synthetic - £11
Super S - 10W40 - £11
Super FE - 5W30 - £16
Super M - 15W40 - £11
The 1liter bottles are also half normal price.

I have a new MX-5, so am going to try & get some Mobil Super FE - 5W30 - £16. Halfords sell the same stuff for £11 more
#17
same prices in wigan store too,i got the mobil as didnt want to risk the asda

It easier if you Google it but as a guidline the W= weight it is the viscosity of the oil at different tempretures 5W is is thinner than 40W.

By the way, if anyone is doing an oil change, or even if you arent, I reccomend putting some Extralube ZX1 in.tThis can be bought at halfords and it isnt a gimick either. My dad has been using it for the last 15 years and it really is amazing stuff. Early on this year I was selling a honda 125 motorcycle and it had been running pretty rough since I bought it, and I had to compensate by setting the carb to tick over high so it wouldnt stall on cold idle.

Anyway the day I was selling it I thought I might as well chuck abit of this zx1 in and see if it helps. And by god it did, it was like a completely different machine, ticked over just fine at normal speed and it was a cold day. I wish i had put it in when the bike was mine lol. Ive put drops of it on bike wheel bearings and the wheels just spin forever. Im gonna put some in fabia once my oil level is low. It can be quite expensive, I think it 17 quid in halfords at the minute but it is worth every penny.

@thabiz
Could you explain how putting something in your oil would help with your fuel/air mixture?

Mobil stuff at same price in ASDA, cribbs causway Bristol
ASDA brand reduced to £10
#24
went to ASDA Basingstoke and Mobil brand still have normaln price 22-25 per 5L bottle. Must be store specific then or my ASDA dont wanna loose money :D they tried to charge more for the ketchup anyway haha.was 1.07 and i came up 1.46 but i've asked and they had to correct it :)

" Ive put drops of it on bike wheel bearings and the wheels just spin forever"

you should patent it! free energy
#26
In the end the Mobil Super FE - 5W30 from Asda in MK was £22

You misunderstood, what I was saying was that without zx1 I had to set the carb to a high tickover as it would stall when cold, engine not ticking over smooth. But when i added the zx1 it was smooth so therefore I could set the carb to a normal slow tickover.

" Ive put drops of it on bike wheel bearings and the wheels just spin forever"

yep wish I could lol.

Anyway trust me that zx1 stuff is no joke. Try it.
#28
I'll rephrase my question.

Could you explain how putting something in your oil would help with your engine tickover when cold?
#29
XP1 is just ZDDP, it won't even have any effect on anything until the engine is over ~50˚c.
It is also bad for newer car's emission controls, hence low SAPS oils being specified like that in the OP.
#30
Been to Asda today and this offer was NOT on for the 5w40 but was on for the 10w40

5w/40 was £18 for 5 litres so im guessing this offer has expired.

I put some in the fuel tank and some with the oil. Obviously it resulted in better lubrication for the piston as my bike ran sweet (both from cold and when warm) like it had never done in the year that i had owned it. If you dont want to believe me then fine.

It works, ive seen the proof of that many times.

The W has nothing to do with 'weight'. It designates the cold or 'winter' viscosity of oil.

Asda Thurmaston only had semi-synth 5w40 when I was there over the weekend :(
#34
Still available, cheers OP. Picked up 2 in Steveange branch today, had about 5 left.
