i use the mobil stuff, not because of any media, or being told otherwise. Just becuase it does the job, and cant see why i should change. Its not an highly tuned engine that needs exact components.
Its a 12 year old 8v golf gti, with 125k on the clock. lol
I'm not saying Mobil oils are bad, and they clearly do the job, particularly in your instance.
But you sort of hit the nail on the head - yours isn't a highly tuned engine. Maybe you should take a trip to a race circuit on a mid-week test or Friday-practice day, ideally when the BTCC or BSB are there.
Have a mooch round the back of the paddock garages, ask a few mechanics, and look for what oils they actually put in the engines. You will
not see Mobil, but you will see a large majority of either Castrol or Fuchs Titan in cars, and Castrol, Motul, Fuchs Silkolene or Rock oils in bikes. Maybe that would give you food for thought.
All I am trying to say is that Mobil are
not as good as they would have you believe - and this is simply down to the inferior basestocks which Mobil, along with virually all the American orginated oils use. And as I said, the European Union have made it illegal for the basestocks which the yanks use to be classed as 'synthetic'. A true dictonary (and encyclopaedic) definition of 'synthetic' simply means 'man-made' - so digging up some million year old dinosoar mineral oil, then refining it and re-refining it is NOT man-made - yet this is what a Group3 basestock is, and is exactly what the yanks use as 'synthetic'. A true, geniune synthetic has to be man-made - in laboratories, with boffins wearing white coats, geeky goggles and kinky rubber gloves - and these
true synthetics are either Group4 basestocks (called Polyalphaoelefins - PAOs), or Group5 basestocks (called Esters, and also include Ester derivatives, such as di-esters, tri-esters, etc).
At the end of the day, it is true that 'you pays your money, and you makes your choice' - but sadly, marketing does seriously skew the myth from the facts, and furthermore, Mobil oils are generally way overpriced compared to genuinely similar oils. Oh, and by purchasing Mobil oils, you are actually proping up the US economy, when I think we need to be looking after companies much closer to home!
