Just been in to Tesco today (Congleton) and the 4l own brand oils are reduced to £4 (from £16-£20 a bottle.
There was 5/30 synth and 10/40 semi.
Grab it whilst it's cheap!!!
The 10/40 says A3/B4, will this be okay in my v70 petrol? usually use 10/40 anyway

I always wonder about this stuff. I need to do an oil change on my Escort and Capri but, wondered if this stuff is better than old oil ?

please qualify why you say this, there are specs that oil must meet if you put the letters on the can it must meet that spec, or are you suggesting Tesco would lie about oil spec?
I don't work for Tesco!

I don't work for Tesco! Tesco, sainsburys, asda, morrisons, and any other that you can think of, all sell oil that is nothing like what it claims to be. There is a reason why it's cheap, and that is because it's only good for lubricating your gate hinges. Think about it... If it was any good, it would be competing with Comma or triple QX. I run my own garage, so I'm more than happy when people ignore the warnings and put cheap oil in their engines. More work for me! Another way to look at, would you put the cheapest, nastiest, no name tyres on your car? They pass an mot, so they must be ok right???

if Tesco or any supermarket sold an oil with a specification to any American or European specification and it was gate oil and as you have intimated would give you more work, actually destroyed an engine you would get that oil analysed and if it didn't meet spec then court cases would be common. I.R.T.E. magazine and engine remanufacturing mag detail many stories of oil specification incorrectly filled causing catastrophic failures, oil technology is checkable in a laboratory. if someone uses it and to a correct spec in their vehicle if it failed AA/ RAC would assist and it's a certainty that gutter press and automotive publications would have picked up on the stories. Remember open market supermarket petrol killing lambda sensors due to high silicon content? lots of Vauxhalls but other makers too, not worth them taking that kind of chance.

Remember open market supermarket petrol killing lambda sensors due to high silicon content? lots of Vauxhalls but other makers too, not worth them taking that kind of chance. Nice ramble. Engine wear due to bad oil occurs over time, it doesn't destroy it overnight. So unless your going to analyse and record data at every oil change scince new, good luck proving that it isn't normal wear and tear. You won't find anyone willing to take that case anywhere. Turbo failure is a good example, knackered bearings due to sludging is common. You mention supermarket fuel, go talk to any diesel injection specialist about injector/pump wear from supermarket diesel. It's a nice idea that you could hold the makers of such things accountable, but in reality it doesn't work like that. If you want to save a few pounds by putting cheap oil in your engine, go for it. But don't complain when it costs you 100x that amount further down the road.

The supermarket oil will, without question, meet its claimed specifications. It just will.
However, it is normally reclaimed oil. This means that although it will meet the specifications, that's pretty much all it will do.
As an example, I can cover 100m whilst running. Therefore I am a 100m sprinter. Usain Bolt can also do that. Who would you put your money on to do a better job?
The supermarket oil will be fine for topping up between changes or used in a light use engine. I wouldn't use it in any other way. But then, I won't use Comma or Triple QX either... Or Castrol or Mobil. I'm slightly fussy. 😉

Its like everything else and its perfectly explained above - its not cheap if your engine fails 50,000 before its normal life expectancy - same has cheap tyres yep they might hold air, be made of rubber and be round in shape - has to how long they last and how well they hold the road when you really need them to vs a high quality branded tyre is another thing entirely

And what do you rate?

I shan't weigh in on the whether supermarket oil is better / worse than any other brand, but what I thought I would like to add to this conversation is something I picked up from a book recently. Four Stroke Performance Tuning by A. Graham Bell dedicates about 70 pages to oil specs if you're particularly interested... I skim read it!
In the book he says be careful about the wording of oil approval specs (API and ACEA standards). An oil that says it "holds ACEA A3/B4 approval" is potentially quite different to an oil that says "it's recommended for applications requiring ACEA A3/B4 specification". The latter example does not necessarily meet those standards, its just what that brand suggests you use, it's no guarantee of quality.

I do remember reading a Valvoline spec book in around 2002 of oils specced for 75000 mile oil changes but it was £75 for a gallon or 5L cant remember which. never used it or seen it used but rep said idea is to keep vehicles on road rather than in being serviced, we also did a ball park comparison and materials were similar cost with just savings in labour. not seen or heard of this type of thing since does it exist or did all vehicles using it fail before 75 000 miles?

I worked at Ryder Truck Rental from 93 to 2001 & we had something along those lines. As you say the idea was long stints (can’t remember how long, but long) between oil changes, again as you say, saving on labour & down time for the truck off the road. We only had it for a trail period of about 6 months. Problem we found was, they all burned a bit & all dropped a bit (as 80’s/90’s trucks did) so at something like 5 x the price a litre what you saved on servicing cost you more than lost in top ups

too up at that cost would be prohibitive. leigh environmental refuse trucks had some weird extra filter gubbins that made oil changes at huge mileages if I remember correctly it also had a reservoir which added something I guess like stp or the like that replaced certain additives.

For me my Stag was the convincer as well as the Merc and a Mondeo -Stag : Gained 10PSi at hot idle and kept that between oil changes when using VR1 : Unipart 20W50 could not do that. -MGB : I used to always run cheap 20W50 and despite being on a 10k Ivor Searle engine, the hot idle oil pressure would drop to around 25PSi after a few months of the oil being in the engine. -Mondeo : It strangely was slightly noisier on Triple QX. I never had that problem on Mobil 1 and the engine did 325k on the original engine, bar the head, which had new valves at 210k, due to them burning out -Merc : That ran noisy when hot. I originally thought the mains had gone! With VR1 again, it held better oil pressure right up to the 5,000 mark oil change interval and I did drive that car like a modern (i.e not baby it and have a sea of traffic behind me ). It never went noisy after this either, including when I left it idling in the traffic of the Laon Historique. But there are alot of people here (and possibly on here who will run cheap tyres and oil .).

I always use Mobil Super 3000 (formerly Mobil Synth S) in my wagon but that's probably more out of habit than anything else. I have used Petronas Syntium 3000 as a top up from time to time as ECP frequently have it on sale.

My car is quieter with Miller's nanodrive compared to the vw quantum oil, both the same grade. The Miller's is twice the price though. No idea how you judge the long term effectiveness of oils on your own car.
Anyway, I'm not tempted by cheap oil.

Typical attitude it seems, in many walks of life, is that 'Cheapest is always Best'. . . . . . . yeah, course it is . . . .

I think it depends on what you are intending to do with the vehicle long term. A oil and filter change with any oil that is vaguely on spec is going to be better than running with whatever was cheapest to the garage when it was last serviced 20k ago... Clean oil every 5 or 10k doesn't do any harm.
VR1 is fantastic at holding engines together on a racetrack (or on the road) and is the only oil I've got across that will consistently give Rover V8 engines oil pressure at idle when worn and warm.
