I dont understand, why do people fork out extra for Castrol, Shell, Comma etc.
Wilko's own brand or Asda's own brand will be just as good, minus a few cleaning agents the competition might give.
It all must come from the same refinery, unless ASDA has its very own oil refinery for its oil. The expensive brands just add things to it, but your basic bog standard 10w40 will be exactly the same raw oil as any other brand.
Why pay more?

Because, a) This bit is wrong, a large part of the oil is the base stock quality and selection, and b) those extra's you refer to are called add-packs, and whilst they may only make up a few percent of the oil's makeup, they're very important in terms of performance.

What performance? All oil needs to do is lubricate and prevent overheating. Has a car ever failed on a life long diet of Asda own brand oil? I'd love to see evidence of this. Not a troll thread at all, funny that the only idiots claiming troll are the ones with zero argument on the subject

You should get that looked at.

What performance? Oh only all the anti foaming, visosity modifying, EP, anti-wear, oxidation/acid formation prevention and friction reducing additives....

But still, if there's no difference, you won't mind running your car on Asda's finest sunflower oil to prove your point will you?

Seriously, don't bother. Look at his history to see how he likes to talk nonsense.

ALL oil sold has to meet quality regulations in the UK.
Calling it frying oil is just ridiculous with no scientific proof that its any worse than any other brand.

Your back must be putting you in a bad mood.
Seriously if you have no evidence to show the differences in oil, just shut up thanks

It's the terrible seats in my 04 Astra G. Really buggers it up.

The differences in oil? Well, the olive variety isn't the best when trying to utilise something that needs it to be really hot. Like a good old Yorkshire pud. You need an oil with a good smoking point. I think sunflower or veg is good for this.

If you check the bottle, you'll find that a lot of those specifications that the cheap oils 'have to meet' actually is worded more like:
'Performance level of an API SN/CF, ACEA A3/B3/B4, VW 502.00, 505.00, MB 229.3'

etc, etc.

It won't say it's actually certified to VW502.00 or Mercs regs, etc, because chances are it isn't. Buy a decent oil and it will say it's certified by Merc or VW, and it'll be on the manufacturers list for the certificate for it too.
5w-40 tells you very little, the grades are so wide one manufacturers 10w30 is the same as someone elses 5w-40, and it tells you nothing about how stable it is, or how it's going shear down or age in use, even the API/ACEA gradings won't guarantee what basestock has been used, whether it's cheap ste with masses of shearable viscosity modified added or whether it's top quality Type V's which meet the multigrade requirement through basestock quality alone.

Still, report back on what that sunflower oil goes like.

Guess that's why you're looking for an estate car with a nice big budget of £1000. I'm sure you will get something brilliant for that money. Though dont expect it to have been run on Castrol GTX

Interesting thanks, didn't know that.
Though anything certified by Mercedes is probably a bad thing

Why would that be an issue?

According to you, they are all the same?

I suspect the Wilkos stuff, in a basic petrol engine will be fine, change it once a year or every 10,000 and the engine will last as long as the car.

The main things are warming an engine up, a degree of mechanical sympathy and clean oil on a fairly regular basis, whether its Mobil One or Discount shop own brand isnt really going to make that much difference on say 1 1.6 Focus, on an M5 it may make a difference but it probably wont be what finishes the car off, usually rust, accident, random unrelated failure like a cam belt or just being knackered.

Engines generally dont fail based on grade/quality of oil changed to schedule.

I say that with a few caveats, turbos usually need some kind of synthetic and spending more isnt going to do any harm but spending less might do, it might be the difference between an engine doing 250k and 300k, i.e. largely academic for most cars.

Unless you buy something older with flat tappets and then wonder why the cam lobes have dissolved.

Oil of Ulay's what you need, I mean, if it's called oil, it must be ok? Or does it work out as too expensive? Plus, they probably only do it in one viscosity. Hmmm. Er, fish oil, that's cheap. Or why not just use engine oil that's been drained out of someone else's car? Probably get that for nowt? No point in spending anything if you don't need to, right? It's not like an engine is difficult or expensive to fix if it goes bang, so why worry? Plus, once you've put oil in it once, why would you consider the need to replace it? It's just more oil......might as well leave the original in.

Anyway, I've decided you're probably right.
