FULLY SYNTHETIC ENGINE OIL 5W40 5LITRES £10.00 ASDA

veralumveralum

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

    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?
    xigent
    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

    from memory (its down in the shed) its SL/CF ACEA B3 B4

    It looks good for the price, has it got any VW numbers ? eg 505.01 or 507.00 cheers - Stuart.

    Just bought a couple from Stevenage. No VW numbers though, just what veralum said.

    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

    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.
