Bargain. Double that here.Just bought some.
Tesco own brand fully synthetic 5w30 4L reduced from £20 to £10 with a club card. Meets most manufacturers specs.
Serious bargain I thought!
Tbh I doubt it even then. Pretty much any modern oil will do. Cheap oil changed frequently has to be better than expensive oil stretched out to 20000 miles.Fully synthetic means nothing with modern oils.
As for manufacturer's specs, every manufacturer has several specs.
You really need to know what spec your engine needs, as putting in the wrong spec although not likely to cause any short term issues, can cause long term issues.
That's about the size of it.Tbh I doubt it even then. Pretty much any modern oil will do. Cheap oil changed frequently has to be better than expensive oil stretched out to 20000 miles.
I'm sure you'll believe what you want, but I wouldn't personally use the wrong oils with a VW PD engine, or anything with a wet belt, regardless of how often you change the oil.Tbh I doubt it even then.

MTF = Manual Transmission FluidI know someone who is a PhD in chemistry and works for one of the big international oil companies. When asked what engine oil he uses, his standard reply is "Whatever big-name brand is on special offer".
The one area where I have found a difference in oil performance is manual gear boxes, where the oil is not just a lubricant but plays a role in the operation of the synchro and there's a term "MTF" (motion transfer fluid?) is in use. Rover and Land Rover have long specified a gear box fluid called MTF94 and Honda have their own MTF. My own experience is that where MTF's are quoted, the gear change can be significantly affected (adversely) if some other fluid is used.
There was a legal case in the US some years ago when a ruling was made that the word "synthetic", when applied to lubricants, has no technical meaning and is merely a marketing term.
That's interesting, as I have been experiencing a slight difficulty in shifting gears in my van after driving for about an hour. Thought It might be a warn linkage issue..........................

Huge list of oils compatible with that engine.I'm sure you'll believe what you want, but I wouldn't personally use the wrong oils with a VW PD engine, or anything with a wet belt, regardless of how often you change the oil.
Last time we spoke to our oil supplier about rationalising oils, they had over 15 5w30 oils available to meet specific manufacturers specs, very few of which could be interchanged. It's all about what additives the manufacturers spec, not the viscosity.

I have seen several vw's/fords/etc with wrecked engines.
All due to running the wrong oil.
Most of them were regularly serviced by fleet type places.
Not to mention dpf problems..
I'm pretty sure that stuff sold by places like Tesco would meet the specifications printed on the bottle but some cars need a lot more than just "5/30 fully synthetic"
Obviously if you know your particular car is perfectly happy on generic 5/30 then chuck cheap generic 5/30 in it but unless you're sure, do a bit of model specific research first
Some older cars may even do better on the cheaper stuff with frequent changes.
But if you run something like a modern vw I would go by the book.
You might get away with changing cheap oil every 2000 miles as it might be enough to flush out the crud that builds up.
But even if you like spending your free time changing it and running the risk of stripping a sump plug more often..
Even if you buy the oil at 50p a litre I can't believe it works out cheaper than buying the correct stuff and running a 30k+ longlife service interval?
Not to mention all the trips to the supermarket to fetch it plus the environmental cost of producing the new stuff and disposing of the old stuff along with all the extra gloves used to change it!
But the Tesco oil C3 meets the VW spec?
