(Dunno why the rotation, sorry)
Back in the Yook for the summer break and saw this stuff in Halfords, a UK consumer-level car accessories chain.
Now I like old thick oil, and I don't discount the alleged downside of newer specs with lower zinc levels. (I use SJ routinely and would use SG).
However, I'm unclear what the advantage might be in going as retro as SE, apart from price. I thought this might be priced as a niche product, but it was only 18 quid for 5L IIRC. Quite surprising.
Any educated guesses?
Academic at the moment but might get relevent if I move back to the UK and can find and afford an old car or motorcycle.
