Please note that this is 4Litres ............ most oil is sold as 5Litres ... don't get confused!

If you have a small 3 cylinder engine it will be OK ..... any larger engine and you will be buying another container in addition to!

You are confusing people with you 3 cilinder engine example. I have a 1.5 4 cilinder engine, wich takes 3.7 litres on a change. How about that!!

You may have a point there.

BUT, are you including a filter change? - as the filter can hold 0.8 litre ... you 'may' actually need 3.7 + 0.8 if you do the job properly? Just a thought.

Every 3 cylinder engine would be OK with this.

More cylinders may be OK too ...... check your handbook first is what I'm saying I suppose.

Most top fuels only supply 4 litres. It is still a ace price.

Indeed it is a great price .... if you want the drag effect of Magnatec on your engine - I like my engines free revving.

By top fuels, I assume you mean expensive fuels? Then they supply just 4 litres ..... I refuse to be an advocate of this type of con on a money saving site

I have voted HOT though ... if you have a small engine and don't mind it not free revving this is a bargain!

If you have to buy 2 however, I would suggest one of the FUCH's Oils which come in 5 litres for around £22.

You are wrong again . I did my oil change this week, filter included of course. Filter for this engine capacity, mine 1.5 are small, in mine went 0,15 l maxFilters that take 0,8 oil are found in vans and cars with over 2.4 liter engine . Of course, one should check before buying .

I find that the mineral content upsets the balance of the junipers when mixed with Gin

This is a great deal, magnatec normally comes in 4l containers and whilst I've seen it cheaper, this is still about £10 off normal price. Heat OP.

I bought it because it sat next to a one litre container of the same oil @ £7.00 in our local Wilkinsons (last one though!). I believe the MRP for 4 litres is £34.00.

Link please

How does magnatec stop free revving??!

I couldn't find a 4L option on the website.
Is this an instore only deal?

Magnatec prides itself on 'clinging' to the surface - it is its major selling point ......... I'm an Engineer so will try to avoid technicalities, but this 'clingyness' produces drag - drag stops movement - movement is an expression of free-revving.

I'm confused that you cannot use Google and/or eBay?

this is not really fully synthetic.

Ester !!!! that's the magic ingredient here in Magnatec,, ( although not that much of it ) ,, infact if you look at oils that have Ester in them they are the higher end oils on the market and cost ££££££ !!!

look at is, as a film oil of protecting your metal to metal parts , not drag , but ultimate lubrication and protection and longevity

After all its what jet engines use , and all commercial air craft use as their oil,
Also F1 cars, Motogp , etc,,,

Ester based oils are the ultimate in oil protection,

As an engineer you should understand the viscosity rating. This will be no different than any other 5w30 rated oil. Free revving, lol.

Whats this guy on about above, I have a Vectra C 2.2i Direct and a Espace 3.0 DCi both of my cars can be filled up to just under max on 4 litres from empty, and thats with or without an oil change!!

Check your dipstick it will tell you the max amount in litres, usually 3.5 in the vast majority of cars..

how does this oil compare to asda's own brand fully synthetic , think it retails for £20 ,5l

This is why I tried to make it simple .......

Viscosity is the flow of the oil (say through your funnel) - NOTHING to do with how the molecules adhere to metal surfaces.

3.5 on your 2.2 litre engine - WITH a new filter?

My Honda 2.2 takes over 6 litres .... but, it is a superior engine - maybe that's where I'm getting confused?

Sounds like your Honda is wasting oil...

I have two cars - one take 8 litres and the other 8.5 litres so depends!!!

+++++
Great price & find @blind

£4.34 cheaper than the cheapest in the uk [costco] so worth picking up a few for the average "3 car" family oil changes over the coming year :-)

I've never found an oil filter that took 0.8 litres on a car, more like 0.3 litres max.

I don't know why Honda's 2.2 diesel takes 5.9 litres, it seems like overkill to me.

As for this oil creating drag it would be that minimal that you wouldn't notice it especially in a normal car plus there is oil at the top end as soon as you start it up reducing engine wear. I don't know how well this works but that's castrol's marketing blurb.

I find that using cheaper oil and changing it frequently is better than using more expensive oil and leaving it in for longer.

Also, in my experience I've found people who claim to be engineers are normally pen pushers who like to make themselves sound clever but have no hands on experience at all.

The deal is a good deal and if I see some in my local wilkos I'll get some as my car only takes 3.5 litres with a filter change. It's a 1.6 4 cylinder so this oil would be good for most smaller engines.

All right I've read enough bull now thank you. Not got time to right it all out myself but read here if you want to know what to look for in a good oil upmpg.com/tec…ty/ and here pqiamerica.com/Lab…htm . As you can see there is a bit more to oil other than just getting the correct grade. If you are a anorak/petrol head then you might want one of these also britishv8.org/Art…htm . Now just get the best oil you can for your car and change it at the right time, as the price between a correct/good oil and a bad one is peanuts in motoring terms and can save you a lot further down the line.

OH, dear .........

Just back in and noticed this is a very old specification oil. ACEA A/B meaning you would be best avoiding if your vehicle has a catalytic converter/diesel particle filter and you quite like keeping it running (ideal for some pre 1992 makes though). Look for oils with ACEA C3 or better (Castrol Edge for example). Use something like this if you are not sure of your oil requirements and then shop around for the best price stores.ebay.co.uk/opi…ils

oil posts are a bullsh!tters paradise

I use magnatec, have a 1600 vtec engine, oil change with a filter is 3.9ltrs and I've never once had a problem with free revving, my engine revs to 9200 rpm, no bother what so ever, just because your an engineer doesn't mean your a mechanic, strongly think you should read up before running your mouth off.

Some of the misinformation here are truly shocking. My car is 1.8 and uses 2.7L of oil. And what the hell is drag effect? In tribology I have heard of viscosity, film strength and adhesion but not drag effect. 5w-30 is 5w-30 you can't have higher drag at the same viscosity.

No I'm not a mechanic, I was a while when doing my 5 year apprenticeship though then I left the Mechanics to their grease and moved into Design.

Of course, your engine will still rev to whatever you want - just not as freely as with modern quality true synthetic oils.

Most folk just need to use the correct oil and a good quality filter. There is no need to bring free revving into the post but if you are into getting the last ounce of performance from your engine then this would be a step in the right direction paceproducts.co.uk/pub…D=3

I had found one here that is suitable for cars fitted with dpf, delivered for a few quid more. 5 litres too.
hotukdeals.com/dea…867

The one i ordered has been delivered and all is fine.

It makes me smile when folk spend time trying to save £10 on a tub of oil that will be in the engine for about 6 months on average yet they don't give much thought to the £70 odd quid they put in the fuel tank that will carry them around for about 400 miles (sometimes just doing short/needless trips).

this is ford spec oil. a1 is fuel economy oil so slightly thinner then other 5w30s

what i have never understood and castrol is they charge mega bucks for there oil but its still only 5w30 a1. this isnt long life or extended drain. most fully synthetics these days are a5. this is the same spec as normal semi synthetics that are alot cheaper
