Just don't :disappointed: - We had the same sort of ridiculous comments in the Redex thread: http://www.hotukdeals.com/deals/redex-fuel-system-cleaner-petrol-also-lead-replacement-both-250ml-1-tesco-instore-2188855

I've given up trying to advise people on here about oil / petroleum related things now, it's just not worth the hassle. Let these people live in their own little bubble. Funny thing is, I've spent years working in refineries doing a mixture of engineering and chemistry, yet the internet is the only place is stands for nothing.

There was a thread kicking about a while ago and had some rubbish posted in it about supermarket fuel. I pointed out that Tesco fuel is Esso in almost all areas of the UK. I was called a lair and all sorts of bad things, even though you can find the information on the official ExxonMobil website (Esso is just the name of their retail arm).

I'm certainly not going to debate with anyone in this thread, but choosing oil is quite simple for 99% of people: Buy the cheapest one that you can, that has the correct specifications for your vehicle. If you're changing your oil yearly, you'd have to be doing very high milage for any other considerations to matter.

All the talk about 'additives' in these threads is quite cute. The 'additives' that people speak of are of a very, very small quantity and even in our own internal tests, only made a difference under the most extreme situations - most of which you couldn't replicate in a road engine (because it would be dead before then).

It's no exaggeration to say that we manufactured tests to show that an additive was 'better', passed it to the marketing lot who had a field day, and thus many different 'brands' were born. It was all legal and above board, but some of it was very close to the line back in the 80s and 90s - not so much now though.

Having said that, the marketing still works. I recently spoke to a guy that would only buy a certain brand of oil because "it sticks to the metal" and it had "intelligent molecules"....I kid you not. That was marketing that was used when the product came out decades ago, but of course, it's nonsense ("intelligent molecules" LOL!). It just has a bit less drag (the bottom end the spec allows for) and added zinc, molybdenum and phosphorus to make it 'stick' to things. Of course, that's not even suited to all engines.

Aghhh, sorry, I'm going off on one. Marketing annoys me when it comes to oils. The marketing people I used to work with on occasion used to get as much, if not more than me (and bonuses!), even though they didn't know jack about oils.

Edit - okay, wow. I wasn't expecting this sort of response <3. The self proclaimed oil purists on here usually rate anyone down that doesn't recommend a fully synthetic oil with additives of ostrich tears.

Welcome to the 80's. Where everything was claimed to change your life and do unreasonable claims (People often still believed smoking was good for you). There is a reason the governments around the world started to clamp down on it. This isn't whistle blowing - it's telling you how the industry worked in the 80's (and lots of others - cosmetics and cleaning to name two), with absolutely nothing new being relieved. There is nothing I've said which can't be found in many others places on the web, or even in lessons that deal with the history of marketing.
I wasn't part of the marketing machine, but I was certainly aware of it and we were instructed to remember to pass any information that could help that team on to them.
You also had cartels closely related to this activity: see the Phoebus cartel for example. Marketing back then was embedded into every part of the chain. If you didn't do it, your competitors would.

Again - none of it was illegal - it was just the tests that the industry used was so far from reality that they were of little use to the general public....but strictly speaking, they were true.

I'm not looking for thanks - I'm trying to explain how this situation of people believing a few pence of 'additives' can dramatically change the quality of the oil, as most people don't understand what 'additives' are. I'm spending the time writing these posts because I want to save you money.

The single, most important thing you need to be looking at for your oil is the specifications it has. These are there to ensure certain standards are met. Almost everything else is marketing, if it wasn't and it was important to your engine, it would be a specification (otherwise how would you know it was suitable?).

Heck, I still work as a consultant on occasion, so I should probably keep my mouth shut for self-serving interests. It's just so sad to see the lack of scientific knowledge in the UK. It's at an all time low. We have kids graduating that I've interviewed with degrees who can barely explain the most simple of chemical interactions. The general public is worse: Talking about fuel and oil 'additives' in almost every thread with no understanding of what they mean apart from "it's better to have them m8".

The silly thing is, none of this is unverifiable by using Google and / or speaking to chemists (loads of internet forums out there), but people just can't be bothered to go reading for a couple of hours.

I'm always tempted by Triple QX, but wish I had a better idea of the quality of it and who actually makes it... Some of eurocarparts own brand stuff isn't great. I've always paid the extra few quid for a known quantity like Shell.

Bought thanks..
