They don't actually go out of their way to publicise that fact to the general public, do they?
Perhaps if they did, people would see it as the overpriced / overhyped product that it is.
BTW - if it sticks to metal, like they claim, how do you change it?

Thats right - if you search for it in google - iam sure you'll find the reports of the court case concerning magnetic - when castrol tried passing it off as a synthetic. Another oil company was not pleased (I think mobile) - and sued for false advertising/ false claims. Suprisingly the courts decided in Castrols favour - even though techies agreed it was not a synthetic in the true sense of the word. It is 'synthetically engineered' - marketing speech for mineral oil - with a additve mixed in.

Comma do four different types of engine oils.
They do plain mineral (blue bottles), syntheticaly fortified (yellow bottles), semi synthetic and synthetic oils. What the difference between the first three is I could not say for sure, i.e. how much synthetic does an oil need before its semi-synthetic?

I use Halfords own brand - 5w40 in my zx td thats done 105000 miles- you can sometimes get this on offer - 2 for £30 (5l). This is rebranded - I thnink it's Esso or Texaco synthetic. - Similar to Comma.
Runs fine - no need to top up, no leaks.
Comma and millers oils are good quality oils. Castrol slx II is good - but very expensive

Thank you all for your useful hints on this topic. I did not suspect that the word 'Magnatec' lead to complete new insights (for me at least) into the way customers are mislead by famous firms. It is now clear to me why I didn't find any information about the consistency on the bottle. Next time I go for the cheaper brands and look at the API-specification!

I tried an experiment changing the oil in my xantia td using first mineral then synthetic then repeated again & I found that I was getting about 3mpg more using the fully synthetic which over 6k miles was self financing & I beleive that the fully synthetic made for smoother running & at 196k I don't want to encourage any engine problems

I tried the same, going from mineral, to semi-synth to fully synth. I couldn't see the blindest bit of difference between the three on fuel economy and I keep the figures meticulously always have done. I've got fuel economy figures for over 50k miles on Xantias and I know what makes a difference and what doesn't. The biggest difference in fuel economy I've had was keeping tyres at the correct pressure, second came driving at 70mph (instead of 80) and third comes taking off the catalyst. Oil had no noticable effect neither has the fuel brand.

Hi Guys,
there is someone on the DSeries-L list that used to manage a Taxi company back in the 80's in the USA. He said a lot of engines were killed from 'black death' back then. However anyone that paid the small amount extra for Castrol GTX(2) never had problems.
25years on and I'm still running plain old boring Castrol GTX in my old CX's and DS's. It's been good enough for the last 30+years, so why would that suddenly be no good ???
As for our modern stuff, modern oils for modern times. My CX GTi Turbo is old technology, I run a 15-50 semi synthetic in it. I figure the immense cost of synthetic oil for it is wasted. After all it will have used mineral oils for the last 100,000miles. However for the same cost I can afford to change it's oil twice as often (I change it about every 6000kms). The Xantia and BX's I use the same oil in. Here in Australia it doesn't get very cold, so getting the thin 05/40 or 10/40 oils is pointless.
I've never had an engine wear out, or engine failure in a Citroen. Just keep fresh high quality oil in them, and don't overheat them and they'll last a llllllllloooooooooonnnnnnnnngggggggg time.
