I think the difference between the "severely hydrocracked" synthetic oils is marginal.

Also, to confuse things even further, oil companies use different branding in different countries depending on the local market rules.

IIRC in Germany, it's not permitted to advertise a hydrocracked oil as synthetic - it has to be the real deal.

I'm always on the lookout for informative articles about lubricants and I've just come upon this one. It's a motor cyclist orientated site but the info is equally relevant to us car people. Hope it's informative.

We're all different. I had a Civic to help with a house move (trick rear seats). Swapped for a new Panda Easy. Honda, never again. Mind you, probably won't own a used Panda again. My 63 plate Panda TA 4x4 needed £2k of work at 4 years old so that was that gone. Replaced with a 67 plate Panda Lounge I see locally still. My current 2016 TA 4x4 will go the way of the first. Faultless it isn't. Gutted really.

That is the best article about synthetic oil types I have seen yet. Thankyou.
